NAT and GRE

santonic — Wed, 28 Mar 2012 13:04:48 GMT

Hello.

I have to do NAT for GRE protocol and as i've read here in knowledgebase that can only be done with static NAT without specifiying ports. However the customer also has other services on same public IP address, like SMTP and DNS.

Would this work?

Rule1 - Public_address -> ports 53TCP/UDP -> NAT -> private_server1

Rule2 - Public_address -> port 25TCP -> NAT -> private_server2

Rule3 - Public_address -> NAT -> private_server3 (for VPN GW without specifying port)

Will DNS requests go to server1, mails to server2 and everything else including GRE to server3?
