We have this setup on a SonicWall firewall, but I can't for the life of me figure out how to do it on a new Cisco 5520. Here is what I want to do
External_IP1:25 --> InternalMailGW_IP:25 External_IP1:80 --> InternalWeb_IP:80
The ACLs are fine, it's just the NATing that I can't figure out.
Is there anyway to do this? I know it's probably not advised, but we have a limited number of external IPs and I don't want to go through the hassle of requesting more at this time.
