OpenVPN problem

Hi!

I have problem using OpenVPN.

The vpn works when using wireless connection but with eth0(wired) interface it does not.
When using eth0 it is possible successfully ping hosts trough vpn and thats all.
eth0 does not use router.

Help appreciated!

route output:
wlan0

Re: OpenVPN problem

What host are you trying to connect to via the VPN?

EDIT: and what's the output of `ip a s`?

Re: OpenVPN problem

All looks correct, except you have 2 default gateways when using wlan0 but you say that works so that's a whole other issue

I can't see any problems -- perhaps some kind of firewalling? Do you have rules in your iptables OUTPUT chain? `iptables -nvL OUTPUT` to check. Failing that, perhaps some kind of firewall on the other end? Especially considering some traffic works (icmp and dns) but not others it definitely sounds firewall related.

Re: OpenVPN problem

Funny that with wlan0 everything works fine but with eth0 no.

For iptables I have no rules for OUTPUT.
