First off: I have looked all over for a solution to this, but couldn't find anything.
How can I make OpenVPN's subnet accessible to my LAN?
I have an openSUSE 12.1 box that is my NAT router. The internet is on eth0 and my LAN (10.0.0.0/24) is on eth1. OpenVPN creates the tun0 device, which I also added manually to the network interfaces list in YaST, so to be able to assign it to the firewall's internal zone. OpenVPN's subnet is 10.0.1.0/24.
I have checked "Enable IP Forwarding" in YaST's "Network Settings" and I am using "Masquerade Networks in YaST's SuSEFirewall settings.
/etc/sysconfig/SuSEfirewall2 I have set
The "Network Settings"' routing table is currently empty.
At this point I can reach 10.0.0.0/24 and the rest of the world from my VPN's 10.0.1.0/24, since OpenVPN's
push "redirect-gateway def1 bypass-dhcp".
What I want now is to be able to reach VPN-connected machines (10.0.1.0/24) from my LAN (10.0.0.0/24). How do I do this the right way in openSuSE?
