[Fork] Asuswrt-Merlin 374.43 LTS releases (Archive)

ColinTaylor · Oct 9, 2020

@guss That looks essentially the same as mine so I can't see why it would have stopped working in the way you describe.

Can you remember the version number that worked before you updated?

EDIT: Just seen you updated post. So you were on 374.43_44E5j9527. I'd assumed you were trying to access devices on your LAN by IP address not name therefore whether the DNS server address is valid shouldn't matter.

Could you post the output of iptables-save please?

guss · Oct 10, 2020

You are right. The DNS shouldn't matter.

Here is the output from iptables-save:

Disabling JFFS scripts in the GUI is certainly an option, but it’s overkill. Entware can be removed by:

Eject the USB from the GUI to stop any installed services that may be running from Entware.

Delete the Entware line from /jffs/scripts/post-mount or just delete the /jffs/scripts/post-mount script if nothing else is using it. Same for unmount and services-stop scripts.

rm /tmp/opt

Plug the USB back in and remove the /tmp/mnt/<usbname>/entware directory.

There may be better prescribed ways to get rid of Entware, but this is what I’d do.

EDIT: added 3rd bullet to remove link

Ok, thanks. Will try that.

You know the answer to my question regarding flashing from Merlin to Freshtomato?!
Anyone else try Freshtomato!?

Thanks

I tested some more and still can't find the problem. If I disable "Push LAN to clients" I can't even ping the router itself via 192.168.1.1. If it's enabled this does work, so "Push LAN to clients" does something.

I had a look at the server config and it looks well for me:

I guess my next step is setting up a OpenVPN server on my raspberry pi and check if this works.

Edit: I installed PiVPN on my raspberry and it works fine. So my guess is now, that the OpenVPN is broken in the last firmware for the Asus RT-N66U. Now I use the Pi for redirect traffic with the benefit of a Pi-hole.
Only for work I need a connection without redirection. The Asus works with a TAP interface. With it I can connect to my LAN. But with my preferred way TUN it's not possible. I have now limited the TAP OpenVPN on my Asus for my work ip only and deactivated the second OpenVPN on the Asus. So I'm fine for now.

Thanks for the update. Your iptables output looks fine so I don't know what the problem is. Maybe some sort of bug in the routing table on the router. Anyway, unless you want to debug this any further it looks like you have a workaround.

guss · Oct 10, 2020

Thanks ColinTaylor and yes, for me the matter is settled for the time being. But if the problem occurs with other people and I can somehow help to fix it, I'm happy to help.

Hello everybody

I have an Asus RT-N66U with Firmware:374.43_44EAj9527.

On it I use two OpenVPN servers for many years without a problem. One does direct clients to redirect Internet traffic and one does not.

Since the latest update I have the problem that the option "Push LAN to clients" seems not longer to work. I can connect to the RT-N66U without any problem but I can't connect or ping any devices in my LAN. Normally I only connect to my Ubuntu desktop where a vnc server runs. But I can't connect to my Raspberry Pi either. Only the LAN ip of the RT-N66U itself does respond.

There is no firewall running on the Raspberry Pi and I didn't change the ufw settings on the Ubuntu client:
Anywhere ALLOW IN 192.168.1.0/24
Anywhere ALLOW IN 10.8.0.0/24
Anywhere ALLOW IN 10.8.1.0/24

Does anyone have the same problem?

Can I add something via the custom configuration to fix my problem or has anyone another suggestion for me?

Many thanks in advance
Guss

I've been having the same issue on recent versions. I can't ping any devices on my LAN either; this used to work fine...
I think it may have something to do with changes on the OpenVPN side, because using the latest OpenVPN Connect iOS client (official) I cannot get it to work at all. However, I was able to get it to work using Passepartout.
Additionally, I disabled the Direct clients to redirect Internet traffic and Push LAN to clients options and instead am manually pushing the following:

Code:

push 'redirect-gateway def1'
push 'route 192.168.2.0 255.255.255.0'

guss · Oct 12, 2020

Thanks ngc5195. For me that doesn't work either. I experimented with custom code and manually push my LAN before and just tested your suggestion again. But I can't connect to my LAN.

The most noticeable change between the firmware you previously had and the current one is the change to OpenVPN 2.4.9. In light of @ngc5195's post I'm wondering whether there's a compatibility issue on the client side rather than the router. Can you have a look in the client's log and see if there are any clues there?

guss · Oct 12, 2020

I started testing with Windows 10 64bit OpenVPN client in version 2.4.x. I don't remember the exact version and at some point installed the newest available client (OpenVPN-2.5-rc2-I601-2-amd64.msi). The same problem occurred on my Android (v8.1) phone running LineageOS 15.1 with OpenVPN for Android 0.7.21. Both clients worked perfectly before. So to be honest, I don't think this is a client issue.

But nevertheless I post you the logs.

UPDATE:

@guss @ngc5195 I've just dug out my old RT-N66U and installed V44EA on it. I've configured it as identical as I can determine to guss' setup based on the information posted (although some of the port numbers appear to have been changed in the later posts). I had no problem at all pinging a Windows PC connected to it once I had disabled the Windows Firewall. I'm using the latest version of standard free Android client.

So at the moment I'm at a loss as to why you're having this problem. All I can suggest is that you a) backup your current router settings, b) do a factory reset, and c) do a minimal setup just enough to test the VPN configuration. If it still doesn't work then you can always restore your settings from the backup file.

I can't see anything wrong there but perhaps somebody else can.

Thanks for that. Alas I can't see anything wrong with that either. If you have the time could you post the output of the following (obviously when it's in the "non-working" configuration). But I'm clutching at straws here.

Code:

route -n
cat /proc/sys/net/ipv4/ip_forward
cat /proc/sys/net/ipv4/conf/*/forwarding
cat /proc/sys/net/ipv4/conf/*/rp_filter
ip rule show

I did it twice, once with "Push LAN to clients Yes" and once with "No" and this custom configuration:

Code:

route 192.168.1.0 255.255.255.0
push 'route 192.168.1.0 255.255.255.0'

Direct clients to redirect Internet traffic in both cases "No"

The output is identical:

route -n

Code:

Edit: Oh, I see just now you edited your post. Thank you very much for your time ColinTaylor. It's good to know it's working for you with the same router model. So the problem has to be something else in my case. If I find the solution I will post it.

Edit2: I did a factory reset and somehow bricked my router. It doesn't boot anymore, I can't connect in any way. The poor thing is dead. I have no idea what happened.

Just register to say thank you to John
My router had been running laggy and buggy ever since they stop updating asuswrt-merlin for ac66u
After a firmware restoration and clean install of your latest release, it's running buttery smooth now

What is the main differences with ipv6 setup on John's fork versus ipv6 on merlin

What type of IPv6 connection do you have, native or static?

Native

I don't have IPv6 myself but this is what I see in the GUI:

I have an RT-N66U running this latest version (V44EA) in AP mode. I remember setting the IP to 192.168.101.2 (router on 101.1), and the primary router shows the N66U at this address. Everything works fine, except ... I can no longer access the admin page at the assigned IP address.

I've tried:

Connecting both via http and https
Connecting directly via LAN port
Disconnecting WAN cable, setting PC manual IP to 192.168.0.3 assuming N66U at 192.168.0.1
Same as above with 192.168.1.3 to 192.168.1.1

What's strange is I could swear I remember accessing the admin page after putting it into AP mode when first setting it up a few weeks ago. I know I can just reset the router to regain access, but obviously I'm trying to avoid that given everything is working - plus this has me wondering if this is a bug or by design.

Is there a way to access the admin page while in AP mode? A default IP address it takes if it isn't assigned one?

@djphilosophy Download the ASUS Device Discovery utility and see if that can find it.

Thanks for the reply. It finds it at 192.168.101.2 as well. If I click configure there it attempts to load the webpage, which gives the error "refused to connect" (same as before - should have mentioned that).

Worth adding that I've attempted access on both Linux and now Windows (after running the Device Discovery app just now), so it's not an OS/firewall issue.

Edit: Also tried unplugging the WAN cable, rebooting and running Device Discovery again. Same IP, still no access.
