small must have a default route to big (which I think you already have). If the result is exactly the same, make sure small is configured with DNS servers in /etc/resolv.conf so that name resolution works. Another thing you can try is a source ping from the inside interface on big: ping -S 192.168.10.1 www.freebsd.org See if NAT is actually working on big. If that works, then NAT is not your issue. Try pinging the IP address on your tun0 interface from small. That will tell you if your routing is good. Joe On Tue, 25 Sep 2001, P. U. (Uli) Kruppa wrote: > Thanks for your answers so far.
