hi all, I've searched the list for clues but havent' found a resolution for the following: 1. On a testing network, with seven identically configured routers, four connect and three dont. They are all the same make / model. 2. They're all using different usernames and passwords, and the NAS is reporting that RADIUS is rejecting three of them but the other four are OK. 3. The box _is_ multihomed; saw the FAQ and i've set bind and port to the one address I want and also have recompiled with --with-udpfromto 4. I'm seeing fewer errors than I was, but the sites still aren't connecting. 5. When I connect from another site using ntradping to the same FreeRADIUS all seven usernames / passwords work and I get Access-Accept. 6. At the not workign sites, the routers (Draytek) report that the ADSL is in sync, sending an Access-Request, then nine seconds later they drop the PPP session. auth-detail reports the Access-Request properly AFAIK. reply-detail reports the Access-Accept properly. In the radius.log I get Wed Aug 8 18:17:35 2007 : Error: rlm_sql (sql) in sql_accounting: stop packet with zero session length.

FR is using MySQL if that makes a difference. I'm not that concerned about the redback/***** failures as they are keepalives from the NAS, which is 3rd party (I have no access). Thanks in advance for any pointers anyone can give, and very sorry if my searching of the list missed a solution posted previously!! Andy
