Hi, Is anyone aware of problems with auto proxy arp feature in Linux, regarding ip conflicts? This is a machine with several eth's, on two of them - eth0 (internal LAN) and eth1 (router with crossover cable) - I have proxy arp enabled. eth0 is further divided into eth0 (192.168.220.0/24) and eth0:1 (192.168.120.0/24). What seems to be happening is that all the new windows (2K Pro|XP) machines booting with addresses 192.168.120.x are getting ip conflicts. The same problem seems to be keeping me from using DHCP. If I echo 0 > /proc/sys/net/ipv4/conf/eth0/proxy_arp, then boot the machines or disable/enable the interfaces and then echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp it will work, but this *can't* be the solution. RH 7.2 with kernel 2.4.17. TIA, nuno - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
