RE: [FW1] why not a bridge?



Soem thoughts.... have never seen the sun firewall.... a bridge in its
purest sense,works at the ethernet address level, just a glorified repeater
with some knowledge as to what segment a MAC address is on.

This makes the segements and the bridge vulnerable to broadcast storms for
one thing. This reduces usable bandwidth. One would also assume DOS
potential.

Now a firewall that acts as a bridge could probably handle that... dunno...

I think it is more that as the focus on TCP/IP over the past 10 years has
increased, the use of other protocols and more importantly, non routable
protocols such as dlc and netbios/netbeui usage has decreased to the extent
there is not a big market.
Sorta VHS vs Beta, the market and the marketers chose the winner.

Subject: [FW1] why not a bridge?



Can anyone explain why Sun is the only company that seems to produce a
firewall that runs as a bridge?  I can't see why this isn't a more common
practise.
