Title: Re: [Openvpn-users] Problem with multiple push "route..."

Hi Erich,

 

yes, I tested the interfaces (tun and eth) on both sides of the tunnel.

If I only push one route (doesn't matter which one), the tunnel stays up and everything is fine.

How can I push two routes in one push statement? I didn't find it in the docs.

 

Unfortunately, I have to use TCP to be able to use the vpn in an enviroment, where I only have a http proxy to connect with the outside world :(

But I'm thinkting about another openvpn instance which serves the same but with UDP for normal connect, where I'm not used to use a proxy.

Setting the redirect-gateway of cource is one solution but it has to work without that, too.

 

Thanks for your help.

 

Regards,

Thomas

You checked the tun and the physical interface on both sides I guess.

If you test with a single push, does it happen with either of the two
routes?

Have you tried to add both routes to a single push?

Unless you have specific needs to use TCP I would suggest to stick with
UDP, less hassle.

Checking my own, comparable, setup I see that I actually push
redirect-gateway, which runs in your case.

cheers
