Kevin; I use a 56k dialup modem. It doesn''t matter if you use a dailup modem or Broadband as that interface is defined to Linux and Shorewall in the normal way. You must not add it to the bridge as all data passing through the bridge bypasses the ip stack therefore Shorewall/netfilter will not see it and you will not have a firewall just a bridge. You can attach a workstation or hub to the switch. Steven. On Thursday 14 August 2003 19:28, Kevin Smith wrote:> Sorry, just continuing my thought... > > So you basically need 1 nic per work station?
