ipredator.se and OpenVPN client connects, but no internet

dyce1980

Occasional Visitor
I feel like a straight up noob after running around in circles for the past few hours trying to get this to work. I think I have read every single forum post on the topic and yet I'm still not any farther. Here's the issue:

I have an Asus RT-N66U with the latest Merlin build (says 270.25, but I flashed the 25b).

I want to set up a VPN connection as a client connecting to ipredator.se in the router. After some initial issues with the settings, I have figured out what to enter where and the router is connecting. Here's the log:

The only problem is that with the VPN connected, I cannot access the internet using any of my devices, neither wired nor wireless. I have tried everything I can think of: firewall on/off, playing with the NAT settings, restarting devices, etc., but nothing seems to work. Is there some setting I'm missing or anything in my log that points to an error? Sorry if the answer is obvious but many many people seem to have this issue but I haven't been able to find a definitive answer anywhere.
 
The tunnel seems to be connecting just fine. Test it out from the router's ssh prompt:

Code:
traceroute 8.8.8.8

See if it goes through the VPN provider's network, or through your ISP.

If that works, try again from your PC.
 
Hey Merlin, thanks for replying! As an aside just wanted to note that I really like the other added features and the stability your build brings. My connection seems snappier since I've had it flashed, so thanks for that!

Now to the problem at hand...

Did as you said, here's the result from the router:

Doing the same from a client PC simply times out. So the router is definitely connected properly and passing data to the VPN, just not internally to my LAN. I am still stumped.

Make sure you did flash 25b - the symptoms you report are similar to those that happened in build 25. If you run "uname -a" over SSH, it should give you a March 3rd date.
 
This is what I got:
Linux RT-N66U 2.6.22.19 #1 Sun Mar 3 13:47:06 EST 2013 mips GNU/Linux

Should I try reflashing?

And are there any NAT-related, DHCP-related, or otherwise setting-related aspects I should be considering?

I'm not very familiar with the use of the OpenVPN client to connect to a tunnel provider, sorry. I only did a basic test here using a free account to troubleshoot the routing issue from build 25.

Everything that needs configuring should be on the OpenVPN client page. Just make sure you did keep NAT and Firewall enabled.

Reflashing rarely resolves anything - if it's running without crashing, then it's flashed correctly.

As a troubleshooting aid, you can try this. Run this through SSH:

Code:
iptables -A FORWARD -j logaccept

Now try again a traceroute from your PC. Afterward, check the system log:

Code:
tail /tmp/syslog.log

Do you see any ACCEPT log entries? If yes, then it means the firewall is preventing you from routing through your tunnel for some reason. I'll need those log entry to have a better idea.
 
"iptables -A FORWARD -j logaccept" as one command did not do anything - the screen just flashed and there was nothing in the box below...
 
"iptables -A FORWARD -j logaccept" as one command did not do anything - the screen just flashed and there was nothing in the box below...

That's normal.

What it did is insert a new firewall rule that will log all packets that are usually rejected by the FORWARD chain. The rule will remain in place until you restart the router, or its firewall. We want to see if the FORWARD chain is dropping your traffic, and if so what is the actual traffic that gets dropped.
 
Ok, well I tried running another tracert and it once again went through 30 hops with 1 connection to asusnetwork.net and 29 time outs.

The log looks normal, with OpenVPN STATISTICS, and then this:

[pw.openvpn.ipredator.se] Inactivity timeout (--ping-restart), restarting
Mar 4 19:55:30 openvpn[6373]: SIGUSR1[soft,ping-restart] received, process restarting

Mar 4 19:55:32 openvpn[6373]: UDPv4 link remote: [AF_INET]93.182.163.130:1194

Not sure if that's anything of interest...

But no ACCEPT entries to be seen.

But no ACCEPT entries to be seen.

Then it means the issue is elsewhere, and not with the router's firewall.

Try disabling any firewall/security software running on your computer to ensure it's not responsible for preventing access to the VPN. Also, try setting the Accept DNS Configuration to "Exclusive", and restart your tunnel. Make sure your PC is using your router's DNS and not a manually configured DNS.

At this point, I suspect it's more a configuration issue than a firmware bug. Someone else using the same tunnel provider as you might have more suggestions.

It's all Greek to me so not sure if DROPIN means anything important.

I have tried disabling both router-side and client-side firewalls and AV software to no avail. Also tried changing the DNS Config setting, also no change. So I'm stumped. I'm going to try using the client software and see if I can at least connect that way. But if you have any other good ideas, I'm all ears.

P.S. In the meantime I'm going to find another VPN service that I can use as Client 2 for testing purposes.

I see your tunnel is set on tun0, which is wrong. The firmware should use tun11 for a client VPN.

If you entered any custom config entry for your OpenVPN client then remove anything that sets the tunnel interface name, and let the firmware manage that bit automatically. That way it will use the tun11 interface name that it's supposed to.
 
EUREKA! That was it! After removing "dev tun0" from the custom config, all clients are now connecting over the VPN! Thank you Merlin for saving the day and for this incredible CFW!

Any chance you could post all the options, custom config & certs you used? I can't even get mine to connect AT ALL
