Julian: There isn't much that I can *think* to add. If knowing which
LAN cards I use will help, they're the usu stuf, a dc (forget which chip)
and a Realtek. I admit these aren't superstars, but I just slapped NAT
box together from what was a simple workstation. The IPFW firewall script
is the unmodified 'open' config, that is:
00050 99654 49243070 divert 8668 ip from any to any via dc0
00100 112 26392 allow ip from any to any via lo0
00200 0 0 deny ip from any to 127.0.0.0/8
00300 0 0 deny ip from 127.0.0.0/8 to any
65000 195218 98282299 allow ip from any to any
65535 0 0 allow ip from any to any
Again, I can even live w/ some overhead due to sub-optimal hware.
I only write bec the FBSD NAT speed is less than 30% of XP standalone
speed ! Later....Jet
