OK, I understand what's happening, I think, but I need to change it.

I was running my client IPX-only and connecting to a BM VPN, no problem,
but I couldn't login remotely.

Reinstalled my client as IP and IPX, now I can login.

But my local machine is now very slow whenever I'm on the VPN (not
logged into the remote server, just logged into my usual local server.)

What's up and how do I fix it?
