How do I add extra IP addresses to my WAN side interface on my ASA 5505

Unanswered Question
Sep 21st, 2007

I have 8 IP addreses from my ISP. I want to use two of them on my new ASA 5505. I have configured one of the interfaces with our primary IP address but want to add a second. How do I set up the ASA 5505 to use more than one IP address on the same WAN Interface?

I have this problem too.

you use them with nat. and then if you need to allow inbound access to one of those addresses, you need to create an inbound acl.

Thanks. Now,,,, how do I "use them with nat"? Could you please elaborate? I'm new to the 5505.

And,,, could you please explain how I "create an (appropriate) inbound acl"?

As you can see from the links I provided, there are plenty of people doing that already. I see no need to reinvent the wheel - or hold people's hands as the case may be. Maybe I incorrectly assumed that as an "IT Manager" you had the motivation to read the actual documentation. I guess I was wrong.
