Every lokal IP should be routet via lo0 (loopback) just do an "route add 127.0.0.1 10.0.1.112" on your server. this is done automaticly for the first ip but not for any alias IP. here are some lines out of my rc.conf (FreeBSD 2.2.7) set up the primary IP Adresses -----------8<--------------------------------------- network_interfaces="vx0 lo0" # List of network interfaces (lo0 is loopback). ifconfig_vx0="inet 193.159.181.123 netmask 255.255.255.128" ifconfig_lo0="inet 127.0.0.1" # default loopback device configuration. -----------8<--------------------------------------- set up as many aliases as you need -----------8<--------------------------------------- ifconfig_vx0_alias0="inet 193.159.181.108 netmask 255.255.255.128" ifconfig_vx0_alias1="inet 193.159.181.107 netmask 255.255.255.128" -----------8<--------------------------------------- later on set up routes you need be careful not to use a "." in routenames. -----------8<--------------------------------------- defaultrouter="193.159.181.126" # Set to default gateway (or NO). static_routes="mail2_harz_de ns2_harz_de" # Set to static route list (or leave empty). route_mail2_harz_de="193.159.181.107 127.0.0.1" route_ns2_harz_de="193.159.181.108 127.0.0.1" -----------8<--------------------------------------- Hope it helps matthias -- \\ // N N EEE TTT Matthias Meyser, Meyser@harz.de \\ // eee NN N E T Gesellschaft fuer Informations- und \X/ e e N N N EE T Kommunikationssysteme mbH // \\ e ee N NN E T 38678 Clausthal-Zellerfeld, Burgstaetter Strasse 6 // \\ eeee N N EEE T Telefon: +49-5323-94018 Fax: +49-5323-94011 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
