871 Router and Internet

I just bought a Cisco 871 Router for my home network and I configured it so when I run an ipconfig /all command on my PC it receives an IP address via DHCP from my router and the DNS addresses on my PC are that of my ISP (Comcast). My router's WAN interface is set to receive it's IP address via DHCP from the ISP. However...I cannot access any website from my PC. I'm seeing a local IP and a non-local DNS address. What am I doing wrong here??? I have attached a log/text file that has the following commands:

sh run

sh ip arp

sh ip route


Re: 871 Router and Internet

Hi John

I would insist for a change in the static route defined in your router.

ip route dhcp

Instead of the above statement can you try to point it towards to any of the gateway ip available in service provider network.

You need to check out the same with your SP and get the info..

Re: 871 Router and Internet

I tried that...they wouldn't give me that info. Should I try to point the static route out Fa4???

Nevermind, I just read your config.


Re: 871 Router and Internet

Lots going on here so maybe I missed it.

You access list Comcast_Internet prevents most traffic from returning. In particular you do not allow return traffic from a web server.

Now since you allow GRE and ESP you may have a tunnel I didn't see.

... missed the INSPECT the first time through so that looks ok
