F5 LTM outbound internet

Hi All

 

We have to route specific traffic from host in private LAN to Internet. This is requirement are use for outgoing email from MX server in private LAN. We can not use IP node from default gateway pools as a outgoing IP,and have to use MX public IP.

 

What are the simplest way to achieve this ? do we have to do SNAT with VS, or just do the VS and use MX public IP as a pool ? IRule ?, or else.. ?

 

Please kindly suggest.
