Hi Benny, My Linux NAT is just configured as below : echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE But when doing a "netstat-nat -N" on this linux NAT I saw two lines in the translation table that had same source addresses/ports and differents destination addresses/ports and they had same Mapped public address/port. For a Symmetric NAT the mapped addresses/ports should be differents ? Thanks for your explanations.
