I never got this to work. Instead, I use the recipe found in ipchains on

3.1 Rusty's Three-Line Guide To Masquerading

This assumes that your external interface is called `ppp0'. Use ifconfig
to find out, and adjust to taste.

    # ipchains -P forward DENY
    # ipchains -A forward -i ppp0 -j MASQ
    # echo 1 > /proc/sys/net/ipv4/ip_forward
