Q: PPPOE and Windows NAT issues

I am working on the following setup:

Computer A: Windows 2003 Server SP1
Nic1: IP address 193.168.211.1 Mask: 255.255.255.0
Nic2: IP address 192.168.211.2 Mask: 255.255.255.224

Computer B: Windows 2000 Advanced Server SP4

Nic3: IP address 192.168.211.5 Mask: 255.255.255.224 Default Gateway: 192.168.211.2

Nic1 is connected to DSL modem, Nic2 and Nic3 are connect to Ethernet Hub. I can establish an Internet connection and surf the web on Computer A. However, on Computer B, I cannot establish a connection to the Internet. I can ping both Nic1 and Nic2 from Computer B and can ping Nic3 from Computer A. If I ping an external address from Computer A in resolves and pings properly, if I ping the same domain name from Computer B it resolves but does not ping back. Both machines are configured as domain controllers with AD and DNS installed on each. I have configured DNS forwarders on
Computer A and they seem to be working properly. I think I am missing something in the routing table but I have no idea what. The routing table below is from Computer A. If anyone has an idea it would be appreciated.

A1: I found that since I was using PPPOE to connect to the Internet I needed to setup RRAS with the Route Internal LAN and Demand-Dial option. I then had to add and configure my PPPOE connection under Network Interfaces in RRAS making sure to include to route IP packets on this interface. I then added two static routes in the Static Routes section:

0.0.0.0/0 No Default Gateway and set to the PPPOE interface
192.168.211.0/27 No Default Gateway and set to the PPPOE interface

I also added the PPPOE interface to the NAT/Basic Firewall and configured it
as a public interface.

Computer B is now surfing the web like a champ!
