Tt is capable of passing my public IP into the freebsd box and then when I reboot, since the modem keeps my connection alive I dont change IPs as often...This works very well...but, however, this has caused a new twist: My modem appears to be at IP 192.168.0.1 My freebsd box has 2 NICs in it: WAN = DHCP (connected to the 4100 modem) LAN = 10.0.0.1 When the freebsd box boots, it asks for a DHCP address and the modem hands it a public one...207.227.122.7 for example. This works well...with one exception: Each so many seconds or so, my dmesg is filled with tons of these: arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 arplookup: unable to enter address for 192.168.0.1 Now I certainly know why, but cant seem to solve this. If I try to add an alias IP on the WAN NIC (after DHCP) this works but seems to kill off dhclient so once it gets a public IP it never asks/updates again. I am looking for a solution either in a NIC or route command... I could tell the modem to hand me a private IP but I would prefer to have the freebsd box use a public. Help? -JD
