Greetings all

I was just woundering one thing while configuring a new PAT setup in
our FWSM. You have the option of using an IP range, a single IP or the
IP of the "external" interface as GLOBAL address for the PAT.
I've searched some of the guides regarding this subject but haven't
really seen any recommendation when to use the different methods other
than the possible shortage of ports when using single IP and large
number of computers.

Does anyone have any experience in using the different methods and have
any recommendations? Is there a disadvantage when using GLOBAL
interface instead of GLOBAL IP for example?

Regards
Fredrik Hofreb
