I normally setup my PIX and ASAs when the ISP has issued a range of public IPs, e.g. 5, 8 or 13.
One of these is normally bound to the outside interface and another set aside for smtp email.
The problem I have is that one of my clients are in a serviced office and they only allow ONE public IP.
I'm having difficulty getting my default config to work with just a single outside IP.
The "static" command is returning an error like below.
ERROR: Static PAT using the interface requires the use of the 'interface' keyword instead of the interface IP address.
The line I'm attempting to load is something like the below.
static (inside,outside) tcp OUTSIDE-IP smtp SBS smtp netmask 255.255.255.255
The error returned suggests that I use just the "interface" keyword instead of the IP or name.
Will this work ?
