>From my experience and after reading various posts on the comcast forum,
you can actually use your own modem with a comcast static IP, but it still
have to be an smc model on their approved list. A tech once mentioned that
those models support radius. A different model _might_ give you more
bridging options, where you can disable dhcp and Nat and enable DMZ. You'll
never be able to do a l2 or l3 VPN; afaik that mode only forwards TCP and
UDP, so no GRE. Openvpn, maybe.
But it's always a hate or miss situation since they'll download new
firmware to your modem and you have to reach someone who is not reading
from a script and also is willing to do this.
