Server unable to access internet however internally everything is fine

Server sits behind linksys router/firewall.
configured as DC, VPN (i know but I'm poor), file, dns, dhcp, wins
server.
Up until last night everything was working great. I installed last
nights patches from microsoft, this morning problem. I am looking to
see if I can uninstall patches, not looking promising.
Like I said internally everything is fine. Externally I can't even
ping an external ip address: either by ip or url

However I have NO problems doing anything with systems that are on the
same network as the server. Now I have my DHCP providing external DNS
secondary to the server.

No firewall installed other than the linksys

I'm really lost here. I don't even know where to start looking

Update I can Remote Desktop in from outside, and the system will
respond to VPN requests. However, I still cannot get this thing to
finish an outgoing request

Thanks in Advance

Enable VPN in DC may have a name resolution or connectivity issue. Posting the results of ipconfig /all and routing table here may help. Or check this troubleshooting page,

We have some issues here.

1. Is this server multihomed computer? What do you enable two NICs?
2. I don't see PPTP IP for the VPN?
3. If this is multihomed computer, you should not setup the same IP range in these two NICs. If you need to two NICs to connect to two networks, you need to setup different IP addresses.
4. you should not setup DNS to use 127.0.0.1 or ISP DNS.
