Newbie NAT question

[Jonathan]

Hi all,

I've installed pfil and ipfilter on a Solaris 8 machine (2.1.4 and 4.1.3 respectively) and I'm using the following NAT rules (defined in /etc/opt/ipf/ipnat.conf):

map sppp0 192.168.0.0/24 -> 0/32 proxy port ftp ftp/tcp
map sppp0 192.168.0.0/24 -> 032 portmap tcp/udp 10000:40000
map sppp0 192.168.0.0/24 -> 0/32

Snooping sppp0 shows that packets from the private address space reach the PPP interface but do not seem to be translated.

/etc/opt/pfil/iu.ap is:

hme -1 0 pfil

IP forwarding is turned on.

Is there anything that I might have missed? I'm sure that it's something obvious but I'm completely unable to work out what's happening here.

<x-tad-bigger>/opt/ipf/bin/ipmon -t yields nothing.
/sbin/ipnat -l shows that my NAT rules are in place.</x-tad-bigger>
