I was curious about this, too. It looks like the _only_ options are to let it pick the IP on the egress interface automatically, or source everything from lo0. Seems strange that it's not more flexible. This is the only thing I could find, although it won't help if there's no IP on the loopback interface: http://www.juniper.net/techpubs/software/junos/junos85/swconfig85-system-basics/id-10937192.html - Mark -- Mark Kamichoff [EMAIL PROTECTED] http://prolixium.com/ Rensselaer Polytechnic Institute, Class of 2004
