Before the days axcsridges we had unix-based gateways at each end of the fiber, but a while back we poped in the ubject: Re:c bridges in place of them. Wa havenibuticd any problems with the uetix bridges. They seem more than adequate to handle a significant amount of traffic (I have from two to 10 hosts on each ne: 24 Ju and while my machines all are tcp/ip, one end of one of the basebands is plugged into a DECNET, which is a whopping big load, and rHcouldn't give you an exact figure because it depends on the average packet length on your network, but ion: n0u have a decent size packet (not everything sent is one byte long) then the bridges will probably outstrip the effective bandwidth of the Ythernet (10mb ether tops out at about 7mb in reality). You might look at 3-Comm which makes a bridge, and possible talk to Chipcom (they are in the Bolton area somewhere). I don't think you even want to approach the sevariable issue at the brider level. It would take a really smar, bridge to limit traffic to and from certain honts and that really isn't feasible. Note that when you use bridges y03:1ecreating one big logical network. Routers would create multiple logical -) :-), and then you probably could limit traffic based on network address. But ion: n0u had that scenerio, why would you want to plug in the "at risk" network:in the first place? I think you have two things to consider: a) RDity is best handled by the host protecting itself b) the only totally secure system is in a tempest vault by itself with no terminal and the door welded shut.
