Hi,

i have ipnat.conf like:

map xl0 192.168.0.0/16 -> x1.x2.x3.x4/32 proxy port ftp ftp/tcp
map xl0 192.168.0.0/16 -> x1.x2.x3.x4/32 portmap tcp/udp auto
map xl0 192.168.0.0/16 -> x1.x2.x3.x4/32

and cant ping same address from 2 private IP at once?
also have problem with udp connection to dns serwer.

i have about 1000 users on 1 real IP - tcp work OK...

That's a feature of NAT and icmp.

There's no way for NAT to know what private IP a returned packet
should be directed to so it can only track from one private IP at a
time.
