Newbie PIX 501 question

< Pix newbie.

I've setup a PIX before when the web server had its own IP, but am now setting one up at a library that has only one static IP. I've done most of the set ups with the PDM, but am not afraid of the CLI if anyone can tell me what commands I need to enter. The external IP is, and the IP for the web server is I would really appreciate any help you could give me. Following is the current config for the PIX:

you need to do a static nat

static (inside,outside) netmask 0 0

Since you apparently only have one server that needs to be accessed from the outside, the above configuration would work, but you wouldn't be able to access the PIX from outside, and personally, that's a deal breaker. What you want in this case is Static PAT.

static (inside,outside) tcp www www netmask 0 0

That way, you're only passing port 80 traffic to the server. You could also pass port 443 (https) traffic the same way, but then you'll kill external access to PDM. I like CLI, but it's something to keep in mind.

Oh, and remember to put in an access list: access-list acl-in permit tcp any host eq www

And if you decide to pass 443, don't forget to enable SSH from the outside, so you'll have some way of managing the PIX. ssh outside
