The usual advice is *not* to connect two firewalls in parallel, lest traffic that should not can get throught the other. You could keep the other firewall as a spare that can be quickly applied if your current one fails. (I use an known clean CD image in a similar fashion). Sold state switches are pretty reliable these days but I can not get one in a box for the middle of an ethernet cable, so you would have to make one---the components are cheap but breadboard and scopes are not. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
