Ima, ima, nachin. Izcepeno e ama ima.
Proxy-arp se naricha i bih kazal che e edin osobenno opasen nachin.
Imal sym sluchaj administrator da wkljuchwa pc s dwe karti i s dwete
karti w edin i syshti lan, da si puska proxy-arp i da si sloji default
route prez ednata karta.
Administratora nishto ne razbira che e stanalo, no seshtajte se kakwa
mazaliq nastawa.
Izbqgwajte proxy-arp!
Moga da kaja bridging rox - pentiumche na 100 prawi 100 mbps bridging
bez da se zamisli. goworim za 10-na procenta cpu za bridging. Naposledyk
moje i bridge-natiq trafik da se prekarwa prez iptables, taka che nishto
ne gubi chowek :)
Ako li pyk e nujno da se rutira poradi nqkakwa prichina. Routirajte bez
proxy-arp. A ako li pyk kazwate che imate nqkakwi problemi s windowski
mashini koito e zadyljitelno da se wijdat bih wi preporychal da
razgledate WINS.
