Re: Network configuration problem

The original issue may be some things to do with NAT. The laptop issue now is no default gateway.

I removed the Remote Access/VPN Server role from the server and am now able
to access the internet. I can ping the router, 4.2.2.1, and yahoo.com from
the server.

I can also ping the server's local address (192.168.16.2) from the laptop
(192.168.16.11). I cannot ping the server's external nic address
(192.168.0.2) from the laptop, nor can I ping the router (192.168.0.1) from
the laptop.

I cannot ping the laptop (192.168.16.11) from the server.

Nor can I get to the internet from my laptop. Note: I have not added joined
them to the domain.
