Hi,

I got my FreeBSD box set up as a NAT gateway. I got it working partialy; 
icmp pinging from inside to the internet works. But as soon as I try to 
make a tcp connection (loading a webpage or so) it just sits still!

The external interface is fxp0
The internal interface is gif3 (this is  a ipip tunnel)

ipnat.conf is:

map fxp0 10.0.1.0/24 -> 0.0.0.0/32 portmap tcp/udp 1025:65000
map fxp0 10.0.1.0/24 -> 0.0.0.0/32


I find it very odd, because pings travel and are natted without 
problems. What can be wrong?

Thanks in advanced,

Frank de Bot!
