Hi, I have 2 freeradius server: 1 as proxy server, 1 as authentication server. Everything is working fine (Auth. for WPA2, MSCHAPv2 ) until I implement the postproxy function: Then the authentication process did not finished. Putting the vlanid etc into radreply on the authentication radius, everything is working also. Is there something wrong in my config? Version: freeradius/lucid uptodate 2.1.8+dfsg-1ubuntu1 /etc/freeradius/sites-enabled/default: .... post-proxy { post_proxy_log #attr_rewrite attr_filter.post-proxy eap # Post-Proxy-Type Fail { # detail # } /etc/freeradius/attrs: tu-dortmund.de Tunnel-Private-Group-ID :=8, Fall-Through = Yes DEFAULT Tunnel-Type := VLAN, Tunnel-Medium-Type := IEEE-802 Regards hans -- Hans Bornemann IT & Medien Centrum - TU Dortmund Tel. 0049 231 7552132
