1. Add this line into /etc/sysctl.conf

   net.ipv4.ip_forward = 1

  this is the same as  ">>  echo "1"  > /proc/sys/net/ipv4/ip_forward" but you woudn't lose
  settings on reboot.

2. Add this strings into your ipchains script or into ipchains rules

   EXTERNAL_INTERFACE="eth0"               # Internet connected interface
   LOCAL_INTERFACE="eth1"                # Internal LAN interface 1
   LOCALNET="192.168.2.0/24"             # Whatever private range you use 1

   # set masquerade timeout to 10 hours for tcp connections
   ipchains -M -S 36000 0 0
   # Don't forward fragments. Assemble before forwarding.
   ipchains -A output -f -i $LOCAL_INTERFACE_1 -j DENY
   # Masquerade internal traffic.
   # All internal traffic is masqueraded externally.
   ipchains -A forward -i $EXTERNAL_INTERFACE -s $LOCALNET -j MASQ

But if you don't want to masqarade all you internal traffic, but need to replicate
only few ports you may use xinet.d daemon.
