PPPoE to Cable switch, lost inbound access

Good afternoon all,

Here's the short of my problem. On SBS 2003, we switched from DSL to a cable modem connection. Server has two nics, it provides DHCP for clients and firewall/nat funcitons.

We re-configured the server using the connect to the internet wizard. Once that was finished, the server and client computers could access the internet, however, we cannot access the Remote Web Workplace or use remote desktop from the outside(WAN).

Now for the finer points(This is all done from outside(WAN) the network). I have tried multiple re-configurations, including disabling the firewall, however, I have almost a 100% packet loss to the server. Here's the wild part: I am pinging the server with the -t option, whenever I re-configure for a brief second or so while it is configuring the firewall I get 4-5 packets through, then wham, it's gone again. If I do start gettings ping requests back, I can connect to the desktop, etc, but then it stops.

I've tried looking at the bindings, the settings in MMC, etc. It just seems SLOW, like a process is taking up a lot of time on it. The activity is low on the WAN connection, there are no hung/unusual processes, everything is identical as before the simple re-configuration from PPPoE to Direct Broadband Connection

Anyone have some ideas?
 
I should have noted that even though I cannot ping it from the WAN side, the clients still have full internet access.

Thanks again,
Justin
 
One more weird thing....I get ping replies whenever there is an outbound connection (server/workstation is browsing an external website), though it is slow, the ping replies are the 30-50ms range. I could/did make a very slow choppy remote desktop connection....

Any ideas????
Thanks,
Justin
