Configuring SMTP behind F5 - role of SNAT

Hi Brad

Thanks for your response. I had a snat list so removed it and tried adding a snat pool list, but I am getting an error stating one of the SNAT addresses is being used by a pool member. Why would this be giving me an error? My pool members are all on our internal network - hence the desire to SNAT them to an external address.

I would prefer not to wildcard as this LTM is being used for HTTP LB as well as SMTP LB and all the pool members and VSes are on the same internal network.
