hi ya richard...
is your ipmasq gateway to the outside world the same as your firewall ??
- if you know ipchains better than iptables, you can run ipchains
on 2.4 kernels by installing "ipchains" modules in the 2.4 kernels
insmod ipchains
ipchains -L
- several dozen config tools .... mostly for ipchains.. some for
iptables..

- the infamous 3-line ( simplest ) masquerade

# add this to the example for 2.4 kernels for testing
insmod ipchains
#
ipchains -P forward DENY
ipchains -A forward -i ppp0 -j MASQ
echo 1 > /proc/sys/net/ipv4/ip_forward
- change ppp0 to eth0...
- see it allows your inside machines out..
- next step...
- egress filtering
- ingress filtering
- port forwarding, natting
- .... lots of work to keep one occupied for a month
