#define quoting(David Tichbourne) // Every so often my firewall machine seems to // behave like an arp proxy, which I don't want. arp proxy ? // On my firewall console I get messages // like: // // // .... /kernel: arp: 192.168.0.1 moved from 08:00:07:a6:f7:74 to // 00:00:b4:87:00:98 // // later things seem to "reset" back to // // ..... /kernel: arp: 192.168.0.1 moved from 00:00:b4:87:00:98 to // 08:00:07:a6:f7:74 You probably have another machine on the same IP. Double check every machine. Do you have an ether address list of every machine ? // this also happens to my second machine 192.168.0.3 machine as well // (different ethernet addresses of course) // // 192.168.0.1 and 0.3 are behind my firewall and when arp reconfigures // their ethernet addresses // they obviously can see the outside world through the firewall. Why ? Does your firewall filter by mac address ??? Jonny -- Joao Carlos Mendes Luis M.Sc.
