should web ui work? For me clicking anything apart from import config does not do anything, also version etc is not even filled
this is how it looks for me

The WebUI is still experimental, however the basics should work...

Can you try the following command

    WebUI page ('wg_manager.asp') mounted as 'user?.asp'

site2site is what i want to try so i will still try to get this working and see how fast want is if i'm able to to get it to work.

maybe this

is an issue?


also

Strange, if the WebUI wasn't there to be be unmounted, not sure why the WebUI apparently appears to be already mounted? :confused:

Can you issue these two commands
Code:
df

ls -lah /tmp/var/wwwext | grep -TE "user[1-9]+.*";grep -TH . /tmp/var/wwwext/*.title;grep -THE "user[1-9]\." /tmp/menuTree.js | sort
and post the results

This simply means you are using the firmware's WireGuard modules (compiled 2021/01/24), and do not want to override the firmware modules by 3rd-party compiled modules such as @ZebMcKayhan's compiled on 2022/06/27

Indeed a bug... :oops:

While you are struggling with the gui:
https://github.com/ZebMcKayhan/WireguardManager/blob/main/README.md#site-2-site

setting up site-2-site from wgm command line is as easy as:
Code:
E:Option ==> site2site Home Cabin lan=192.168.111.0/24

That is:
Code:
E:Option ==> site2site <SiteAName> <SiteBName> lan=<SiteBLanIp>

Good luck!

Ooh, and by the way: please report back wheither you could keep flowcache enabled.

@ZebMcKayhan thank you, honestly i'm still very beginner with writeguard, starting to understand what even is peer and what ip to assign the interface etc.
Until now it seemed to me, that WG does not consider one peer server and other client, but after I run command you postat it ended with
Code:
[✔] Config Home import as wg22 Site-to-Site (FORCED as 'server') success
, but actually in this case it should be client ...

@Martineau no change after
Code:
uf dev
, and reboot
then I did run
Code:
E:Option ==> www refreshX

        WebUI page 'user1.asp' ('wg_manager.asp') unmounted
        WebUI page ('wg_manager.asp') mounted as 'user1.asp'
        [✔] Restarted service_httpd for WebUI
no change in web ui, but at least no self contradicting errors :)

uf dev output:
1659207294988.png



I did try firefox, as I think it is only remaining non chromium browser, but same, this is in console
1659207495321.png


I guess it should be plus empty string or no plus at all?

No worries! Not too long ago I was there too. Since Wireguard is niether client nor server but actually capable of both a peer is simply what to call it instead.
Usually there is no need of controlling the ips of the peer itself and thats specially true for site2site setup as in the end it will be lan2lan and you never need to care about the peer ip's. The only important thing is that your 2 lan ip must not overlap. I.e both cannot be 192.168.50.x.

Whenever you feel ready, try to enter the command in wgm and see what happens. You won't break anything and whatever peers that are created are easaly removed if they did not turn out correctly.

I will be here helping you out all the way if needed.
 
hmm, I did copied the config that was generated by wire guard manager on asus router to the "server" (server = other side) I did run
Code:
wg setconf wg0 Home.conf
but I got
Code:
Line unrecognized: `Address=10.9.8.1/32'
Configuration parsing error
Regarding IPs, one side is 192.168.50., other 192.168.51. and third one is 192.168.52.x .... anyway third one does not come into play now, i meant 10.9.8.1/32 - IP of the wireguard interface, but I guess i do not need to care about it on asus side and on my side, I can go with 192.168.200.1

... oh, there is something called wg-quick, let's see ... I copied all 6 files that were generated by WGM on asus into /etc/wireguard/ on the other peer and then run
Code:
wg-quick up Home
result
Code:
...
[#] ip -4 route add 192.168.51.0/24 dev Home
RTNETLINK answers: File exists
[#] ip link delete dev Home
I guess it should be ip -4 route add 192.168.50.0/24 dev Home as 51 is the other side lan range

this is how i dir run site2site command
Code:
site2site Home Cabin lan=192.168.51.0/24
, reading https://github.com/ZebMcKayhan/WireguardManager/blob/main/README.md#site-2-site looks like it is correct, maybe when WGM is saying
Import Home.conf on remote site using 'import Home type=device' it is true if remote is another wgm, but I sould actually do
Code:
wg-quick up Cabin
, again, it is explained in your article :)
If SiteB does not consist of an Asus HND router the Cabin.conf should be suitable for running with wg-quick but you might need to make device specific modifications to it to make it work.
Code:
[#] iptables -I INPUT -p udp --dport %p -j ACCEPT; iptables -I INPUT -i OCI -j ACCEPT; iptables -I FORWARD -i OCI -j ACCEPT
iptables v1.8.4 (nf_tables): Port "%p" does not resolve to anything.

Maybe it makes more sense to start (again) on the non-Asus side.

# WireGuard (%p - ListenPort; %wan - WAN interface; %lan - LAN subnet; %net - IPv4 Tunnel subnet ONLY recognised by Martineau's WireGuard Manager/wg-quick2)
so maybe i should i should look into wg-quick2? ... https://www.snbforums.com/threads/session-manager-discussion-2nd-thread.75129/page-34#post-744506 :D

Ooh, 3 sites.... dunno if wgm is capable of this (@Martineau?).

But ok, good to start with 2 sites maybee.

Soo your other 2 sites are not running asus routers? What are you trying to run it on?

If SiteB does not consist of an Asus HND router the Cabin.conf should be suitable for running with wg-quick but you might need to make device specific modifications to it to make it work.

I would assume you should execute:
Code:
wg-quick up Cabin
on the remote site to import the peer. But dont know if wg-quick sets up firewall as needed, but you will find out.
 
For now I had deleted --dport part from PostUp and PostDown lines in the conf file and it at least created the interface on the "Cabin".

Actually siteC is asus router, until now I was running it as openVPN, and we do not need to care for that site for now, siteB "Cabin" is linux machine.

%p is not valid for wg-quick. I suggest you manually edit Cabin.conf and replace %p with the Cabin incooming wireguard port number (should be stated in Cabin.conf ListenPort?)

Do you think no adding dport to iptables can have this effect?
I think i'm missing some kind of routing/forwarding on the linux machine side
I had the same problem with openVpn, but usually it magically fixed itself or i fixed it messing around not know what i'm doing




Regarding your Flow Cache question:
Code:
[✔] Flow Cache is ENABLED
Code:
Speedtest result for WAN

Bandwidth - Download: 912.48 Mbps (data used: 1.1 GB ) - Upload: 789.12 Mbps (data used: 980.2 MB )
Quality - Latency: 2.18 ms (0.12 ms jitter) - Packet Loss: 0.0%
I tried two other servers and it is pretty much the same, hard to say if it is wire guard issue.

maybe i bit worse on the upload then usual, but livable with :)

No... as long as the peers are connected you should be fine. Altough without it Home can probably not initiate the connection but it is enough one side can but ofcourse redundancy if both sides are capable.

Sounds like it.

On the Cabin side, what's the output of
Code:
ip rule
ip route
iptables -nvL FORWARD -t filter

and mask any public ip before postings.

Hmm... this is no router right? This is a device on a network?

Probably IP forwarding is not enabled on the device... try to google too find how to enable it... too tired now, continue tomorrow...
 
yes, it is oracle linux

you are right
Code:
cat /proc/sys/net/ipv4/ip_forward
, but 100% i did set it to 1
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
cat /proc/sys/net/ipv4/ip_forward

I can ping asus router from device behind other side gateway
I can ping devices behind asus router from device behind other side gateway

I can ping devices behind other side gateway from device behind asus router


So weird, that:
1. with open openVPN lately i was never able to ping devices behind other side gateway (openVPN server)
2. ipv4 forwarding got disabled - well mainly this is confusing to me, I'm still new to linux
3. it works with flow cache enabled and even wan speeds are not bad

Also I noticed that with wireguard first 2 "pings" to the device take 100ms and then normal 15ms, while with openVPN it is 15ms all the time.


Thanks for your help.

Great!

Altough I must say I dont really understand why this is working on Cabin side devices, as this is not a router. It would not be normal for packages to appear to this ip for unknown (Home) destinations. Unknown destinations would appear in the router forward zone and since this network is unknown for the router it would follow default route, which means out WAN. Altough I'm not that into all mysteries of ipv4 routing, perhaps some kind of auto-discovery takes place.

Also I noticed that with wireguard first 2 "pings" to the device take 100ms and then normal 15ms, while with openVPN it is 15ms all the time.
This could be a consequence of this auto-discovery(?). Don't know why OpenVPN would be any different unless it uses MAQUARADE on Cabin side so the devices thinks all remote packages comes from Cabin local ip. But that solution should be avoided in my opinion, but might prove nessisary in the end for full access to the clients behind the peer as some devices (like Windows) could be reluctant to accept packages from other networks.

A better solution is if you can access your Cabin router (192.168.51.1?) and tell it to route packages to 192.168.50.0/24 via 192.168.51.2

That would hopefully take care of your ping times.

Speedtest result for WAN Bandwidth - Download: 912.48 Mbps (data used: 1.1 GB ) - Upload: 789.12 Mbps (data used: 980.2 MB ) Quality - Latency: 2.18 ms (0.12 ms jitter) - Packet Loss: 0.0%
What would be more interesting is your speed performance over the Wireguard tunnel. See if you could setup Iperf3 on each side and run a speed test.

Also, check your syslog for kernel error messages (blog mCast...)

Maybee site2site gets away with keeping fc enabled since there are no NAT taking place for packages going over the Wireguard tunnel. Fingers crossed!

other then that I still can't ping stuff behind other side gateway from asus router itself, but site2site all good from both sides

A better solution is if you can access your Cabin router (192.168.51.1?) and tell it to route packages to 192.168.50.0/24 via 192.168.51.2
I forgot to worte that, that is already setup as route

Iperf I may try later today, no promises (i don't have any fast enough wired linux or even windows device at home :( )

I was still not able to get avahi-reflector or whatever other way to get mdns working. I now consider mDNS over site2site VPN nice to have as I was not able to get it working with openVPN also.

Same as reported here:

could be fc interfering. If it seems to affect things you might need to disable fc. If not you could filter them out using I.e Scribe addon.

other then that I still can't ping stuff behind other side gateway from asus router itself, but site2site all good from both sides
Probably because router is using wg21 ip as source. If you ping using br0 ip as source it would probably work. You could also add on Cabin router route 10.9.8.0/24 via 192.168.51.2 (site2site peer ips, which could be a good idea anyway)

I was still not able to get avahi-reflector or whatever other way to get mdns working. I now consider mDNS over site2site VPN nice to have as I was not able to get it working with openVPN also.
I cannot help much with this as Im not (have never) used any of this, but rock-on! And please report back your findings!

Probably CPU limit on the other peer, this is 4 streams

10 streams 30 seconds
I think CPU on other is really the limit here (for WG not for iPerf stream generating as it is on some routers)

Well, doesnt look like there are issues with flow cache. How are the syslog messages? Once now and then or flooding it?

Let me know when you want to add the 3rd peer, or try it yourself and report back your findings!
