Got two units, set up almost identical, one with authenticate, the other won't. Here's the setup on the ARC: eth:1, 12.x.x.x internet connection, specified gateway 12.x.x.1 eth:2, 10.10.1.29 local network connection Radius server IP: 10.10.1.22 When I do a "mon rad" on this ARC, the source-Ip is always the 12.x.x.x address, instead of 10.10.1.29. On a different chassis, the radius packets originate from 10.10.1.29 and works fine. Suggestions? Did I miss something in the config? shouldn't it always originate from the eth:2 when the requested address is on the same subnet as the eth:2 connection? - Joel
