I'm running IPNAT + ARP patch on 2.0.36 to readdress an internal network to the internet.
telnet works, but using an X11 / NFS server on the "internet" side, I am occuring lock ups of the client apps: X11 freezes, NFS clients freeze.. (note: the internet and internal machines are HPs runnning HPUX 10.20, only the ipnat router is linux).
excerpt of my config:
arp -i eth1 -Ds 132.168.x.y eth1 pub
# ip address translation
/root/ipnatadm -O -i -b -S18.104.22.168/32 -M132.168.x.y/32
Please, if you have any clue, mail-me at mailto:Michel.Christaller@cea.fr
I will post in this list any interesting answer...
