I followed the instructions here (http://todayguesswhat.blogspot.ca/2011/03/quick-simple-vpn-setup-guide-using.html) to set up a TCP connection to OpenVPN on my Tomato router. Used TCP because the place I usually surf at seems to have the other ports blocked.

My Vista laptop is able to connect to the router but I don't appear to be getting an IP address. I'm able to access my router's admin page, but I can't see the network at home. When I browse to Whatsmyip I see my home IP.

Here are the results of route print -4 when I'm just connect to the library and when I've fired up the VP connection as well:

Thanks for any advice. I looked at one of the answers but I'm not sure if it applied to me as it said that 10...* was the vpn connection, but I appear to have 10...* when I connect just to the library.

In the tomato VPN Server -> Advanced! Check "Push LAN to clients" option.

just looked and there isn't that option under the advanced tab –  Ian Oct 20 '12 at 8:17
    
In that case you will have to add it manually in you're server.cong with: push "route local_subnet mask" You can do this in the "Custom Configuration" or just ssh into the router and do it in the shell –  Mikec Oct 22 '12 at 11:19
    
thanks. Still new to some of the terminology. How do I determine what my local subnet is in Tomato? Thanks. –  Ian Oct 24 '12 at 0:41
    
If the router's ip is 192.168.1.1 I would say its 192.168.1.0 netmask beign 255.255.255.0 But you should have a menu that shows tomato's routing table. –  Mikec Oct 25 '12 at 14:13
