Operator Posted February 8, 2007 Share Posted February 8, 2007 not sure why you would put the router behind the pc. basically I've done this kind of thing before. my design was inet----router --- switch --Linux box(running proxy server,sniffing tools)---switch---pcs (reason i had a switch in front of the Linux box was to allow an alternate path {link between the 2 switches} so that in the event of the Linux box going down {not likely :D } a quick gw change of the other pc's would fix the issue) if you don't have a second switch i would just do this (could also have the router in between the inet and Linux box) inet-----Linux box(with all appropriate routes etc, sniffing tools etc)----switch----pcs if all your interested in capturing is web traffic then just have Linux box sitting on the same segment as the other pcs but set the other pcs to use it as a proxy server. If you have the luxury of a switch/router that allows port mirroring then it becomes even easier :D Quote Link to comment Share on other sites More sharing options...
Guest ABC Posted February 8, 2007 Share Posted February 8, 2007 the in the middle PC could also be a good hardware firewall :) Quote Link to comment Share on other sites More sharing options...
a5an0 Posted February 9, 2007 Share Posted February 9, 2007 look up "IPTABLES forwarding". Also you will need two or three (DMZ anyone?) NICs. Quote Link to comment Share on other sites More sharing options...
