cisco 837

Hey guys,

Can someone help me with a quick cisco 837 problem i'm having with my 837?

My isp has given me an 8 ip block, the network.

I've assigned to the 837 router and ethernet port using the the 'ip unnumbered' command to allow the dialer interface to "borrow" the IP address of the ethernet already configured on the router.

I've got my PC on the network with the IP: I can telnet to the router from across the net. But I can't seem to ping my pc or connect to it.

I guess I may be required to implement an access list, or add some static routes that allow traffic from the internet to my PC?

this is quite odd, as the PC itself has internet connectivity and I can surf the web etc.

Can someone please advise me.

I've pasted my configuration below:

Any help appreciated, thanks in advance.

i've discovered the 'stateful firewall' setting on my VPN client was causing the problem.
