        Two things:
 a) You need to use ipfwadm/ipchains to enable forwarding (you can  set up
    a packet filtering firewhile while you are at ti ;-)
 b) # turn on forwarding for 2.1 kernels
if [ -e /proc/sys/net/ipv4/ip_forward ]; then
    echo "1" > /proc/sys/net/ipv4/ip_forward
fi

        manoj
ps:      How to check if ipmasq has indeed been built into the kernel.
- ------------------------------------------------------------------------------
# check to see if kernel has masquerade built in
if [ ! -e /proc/net/ip_forward -a ! -e /proc/sys/net/ipv4/ip_forward ]; then
    echo "IP Forwarding has not been enabled in the kernel."
    exit 1
fi

if [ ! -e /proc/net/ip_masquerade ]; then
    echo "IP Masquerade has not been enabled in the kernel."
    exit 1
fi
