Using a PIX 501 firewall through a Linksys BEFSR41 router.
Posted on 2005-04-15
I have a Verizon DSL connection. I am trying to connect my Cisco PIX firewall through the router back to a Cisco 3000 series concentrator. I also have a Cisco IP Phone attached to the firewall. I know the firewall is establishing a tunnel because the IP phone is up and can talk to the Call Manager server.
When I connect a laptop to the firewall and try to log in it hangs after I enter my credentials and just sits there where it says it is loading my personal settings. After a while it will go to the desktop but the login scripts to not run and I am not able to access any anything on the remote network or the internet. If have an exemption in the firewall for the MAC address of the phone.
If I hook up the firewall directly into the DSL modem and turn pppoe authentication on in the firewall both the laptop and phone work with no problems. This leads me to beleive that the problem is in the Linksys router, however I can't find any obvious settings in the router that would cause this.
Does anyone know of a setting in the router or the PIX that I can change to fix the problem and allow the laptop to connect?
