Hello, this is my first mail to a mailinglist so please be patient. I am running three debian radius-servers using freeradius 2.1.12 with about 40 clients for service and wlan authentication. Everything runs fine but there is one client which always causes errors in the log and i would like to ask if somebody had a similar problem and any suggestions for a solution. The servers make no accounting. I get the following error message in the logs: Error: rlm_radutmp: NAS xxx port 0 unknown packet type 16777216) or Error: rlm_radutmp: NAS xxx port 0 unknown packet type 33554432) The Client Configuration is: client xxxx { ipaddr = xxx.xxx.xxx.xxx secret=xxx nas=other netmask = xx } The Client-Network uses pGina for Windows-Radius-Authentication.
