I wonder if there is a way, to do smth like that: fot requests like: arp who-has 192.168.1.13 tell 192.168.4.31 arp who-has 192.168.1.122 tell 192.168.1.31 always answer 192.168.x,x ? i mean I'd have one machine which would have all the MAC's <> IS's like ( arp -s IP M:A:C ) And i'd like to give that 'data' to users, which wouldn't be fake (spoofed). or maybe who has 192.168.0.x tell router1 who has 192.168.2.x tell router2 and so on.. P.S. If i can do smth like that then: 1) Is it possible to do on bridge? 2) Is it possible to make on simple router -- Best regards,Hugle
