Cisco PIX 501 - Setup

[cooldude17]

Hi Guys,

I'm in a bit of a pickle here. Our sys admin was sacked a few days ago, it turns out that he did not configure our Cisco Pix 501. I have been tasked with getting the firewall up and configured correctly. I'm planning on going on a Cisco training course but there are no more available for a few months.
I have tried looking thought the documentation and help on Cisco's site but seem to be confusing myself even more.
What I want is to allow http, SMTP and POP3 traffic in and out and block any unsolicited requests.

Does anyone know of a website that would "talk" me through setting this up or even have a list of commands to enter.

I have an ADSL connection with a Static IP address (No-Nat)

I would be extremely grateful for any help provided.

Thanks in advance

Charles

What I want is to plug the router into the "outside" and connect the NT server to the "inside" and be able to access the internet, SMTP and POP3 from the NT server. The configuration that I've manged to complete so far is below...

Before you go to far I would take a look at the realease notes from Cisco about the latest code. You can upgrade after you config the fw, but you may find that some of what you are trying to accomplish in addition to what you have listed will not be supported by 6.1. A good example is that if your users or a contractor needs to create a client-to-site IPSEC tunnel.

Not sure what the inside IPA is for the server providing the services, but the command...

static (inside,outside) tcp x.x.x.x http 192.84.7.101 http netmask 255.255.255.255 0 0

will allow port forwarding from you outside interface(x.x.x.x) to your inside server. You will also need to add an access-list to allow the traffic to pass such as...

access-list 101 permit tcp any host x.x.x.x eq http

you can also look at

hope that this help!
