FreeBSD onepafw1 4.6-STABLE FreeBSD 4.6-STABLE #2: Thu Jun 27 16:12:37 CEST 2002     fabien@onepafw1:/usr/obj/usr/src/sys/FW  i386
>Description:
When using masqueradinig with ipnat, 2 boxes from the private network
can't access the same destination "at the same time". Same problem with
3 firewalls (all 4.6-STABLE, ethernet interfaces fxp, xl or tl). The
configuration was changed to ipfw + natd, no more problem.

>How-To-Repeat:
Simple configuration for ipnat:
map fxp0 192.168.0.0/16 -> 123.123.123.123/32 proxy port ftp ftp/tcp
map fxp0 192.168.0.0/16 -> 123.123.123.123/32 portmap tcp/udp 10000:65000
map fxp0 192.168.0.0/16 -> 123.123.123.123/32
and for ipf:
pass in from any to any
pass out from any to any

Log on 2 machines on the internal network, ping the same external IP at
the same time: 1 is blocked. Stop the ping working, the other will then
start working.

>Fix:
none (well, use ipfw + natd :P)
