Connecting to a PIX 501 Firewall though a Linksys Wireless Router
Posted on 2007-03-27
I'm setting up a wirelss connection in a coffee shop and am using a linksys wireless router in conjuction with a Cisco PIX 501 Firewall. I have been given a static IP address from my ISP. This address ends in .82 and is assigned to the linksys router. I then use the standard internal IP scheme (DHCP) for handing out IP's to any wireless users that may want to connect to the internet. (192.168.2.100 - 200 range). The outside adapter on the PIX is set to 192.168.2.2 and then the inside adapter is translated to 192.168.1.1. I then have 2 Point of sale computers connected directly to the PIX setup on the 192.168.1.1 schema (but with their own assign ip addresses). These 2 computers are behind the PIX Firewall for obvious security reasons. The only problem is I'm trying to connect to these internal Point of sale computers via a VPN connection. In my VPN client software I can't make a direct call to the internal IP address of either of these computers because it's a generic internal IP scheme. I try to connect to the IP Assigned address of .82 but that just tells the VPN software to try and negociate with the Linksys instead of the PIX. How do I tell the Linksys to handle this VPN request? Do I need to setup port forwarding or NAT or DMZ or something? I had this working a year ago and don't remember having this problem. If anyone has any ideas how I can setup the Linksys to handle this VPN connection and push it through to the PIX I would really appreciate any suggestions. Thanks!
