Forwarding port with pix501 from outside ip

by st0neganesa . Updated 18 years, 7 months ago

Ok, I have a VPN and am able to connect to our outside computers via PCAnywhere through the internal IP’s. Now, I want to be able to connect from a computer outside our VPN. We are using a Cisco Pix501(192.168.3.1), actiontec GT701(xxx.xxx.xxx.158) for DSL modem. I have tried forwarding the port from the dsl modem to the internal ip of the computer, this unfortunately didnt work. I tried to form a static between the DSL modem and the computer (192.168.3.202) using this command:

Static(inside,outside) TCP xxx.xxx.xxx.158 5631 192.168.3.202 5631 netmask 255.255.255.255 0 0
and
Access-list acl_out permit TCP any host xxx.xxx.xxx.158 eq 5631.
Also using commands replacing TCP and 5631 with UDP 5632.

Now, none of this is working, I am wondering where I am going wrong in my train of thought. Would I need to forward ports from dsl modem to pix, then pix to computer? Am I just not getting something correct? Should I be able to simply forward ports from the dsl modem to the computer’s internal IP? Or is this just completely impossible?
It’s been about 4 months since I’ve dicked around with this network and its equipment, and any computer for that matter.

Any help as to what needs to be done, either specific or reasonably vague would be excellent!
