Hi I have my FIREWALL BOX with address 4.3.2.1 (eth0) and local address 192.168.10.0/24. Now I have SNAT: iptables -t nat -A POSTROUTING -s 192.168.10.0/24 -o eth1 -j SNAT --to 4.3.2.1 I would like to make SNAT with i.e two external address. iptables -t nat -A POSTROUTING -s 192.168.10.0/28 -o eth1 -j SNAT --to 4.3.2.1 iptables -t nat -A POSTROUTING -s 192.168.10.128/28 -o eth1 -j SNAT --to 4.3.2.2. It is good solution? Should I make alias for eth0 with address 4.3.2.2? Thanks for help and sorry for my English. Best regards T.
