I'm new to the PA 2050.
I'm trying to determine the best way of forwarding multiple incoming services on multiple external addresses to multiple internal servers. My PA 2050 is set up in L3 configuration. I have NAT policy rules for all my external->internal address pairs.
My delimma: I have several internal SMTP/FTP/WEB servers behind my 2050, listening on several external addresses. It appears I can NAT each service as a separate NAT policy rule, OR, I can leave the 1 to 1 NAT rule and create a security policy for incoming traffic from "untrust" -> "trust", "any" source address, and select the destination server and application/service to forward the traffic on to. Or can I? Is one more efficient and/or flexible than the other?
Yes, both are viable solutions. It would be more efficient to have the single NAT rule and configure the app/service int the Security rule.
