Re: [Openvpn-users] --redirect-gateway makes DHCP-ip default gw [SOLVED]

I am having problems with 2.0 server (1.6/2.0 p2p work fine) between W2K and Linux. Tunnel gets set up successfully (ping, smb works), but the w2k routing table looks strange to me. The tunnel entries are: 1 1 1

The routing table above looks correct. Windows does not support true Point-to-Point tunnels as the TAP driver is currently implemented, therefor OpenVPN emulates this by using a /30 ( subnet.

I'm lost here. When doing p2p (with 1.6 or 2.0) I get .4.0, .4.2 and .4.255 in the routing table. Where can I read up on this? I should probably do some googling on routing, 'cause I still don't quite get it.

When you are assigned IP address, .5 is your gateway. .1 is OpenVPN's IP address yes, but not on the /30 subnet that has been assigned to you.

I tried out --redirect-gateway, but that added as the default gw, which obviously did't work.

That's what it should do.

Bloody silly me. I could not ping, so I never bothered to look beyond the firewall. It was blocking outbound traffic from .4.0. Everything works now. You've helped me a great deal (I've spent the weekend looking into this :-))

Thank you very very much!
