I'm not an expert but I just got done servicing a BCM50. There is no serial port on the BCM50, so where would you hook up a modem? You would have to use a dial-in remote access server like in the old days. Then you could connect the remote access server to the BCM50 by Ethernet.

The thing to do instead is to use a VPN or open a port on th router.
