I thinkt hat depends on the cable bridge. if they work like my ISDN,
then you end up with this :

Cable -> Bridge -> NAT -> computer -> MASQ -> LAN

In which case it's not really a bridge but a router. This can make
life difficult with some protocols (in my case, IPSEC and CIPE) that
rely on exact point-to-point connections. (and which actually *ASK*
the IF for it's IP address, so it can talk to the other side)

Now, if the bridge acts as a true bridge :

Cale -> Bridge -> computer -> MASQ -> LAN

Then no, there's really nothing to be gained by getting an internal
cable modem.

Oh, and if anyone ahs a Linux compatible Internal ISDN Modem, please
give me a yell. While the router is nice, I'd like to use CIPE and a
few other thigns that don't like a double MASQ/NAT layer as shown in
the first example.
