I have been seen this weird message for two days now. I setup PPTP and IPSec (ikev1) with freeradius + mysql. In both cases I see Access-Acccept and in Accounting-Request I see these two message: WARNING: Empty preacct section. Using default return values. WARNING: Empty accounting section. Using default return values. I have no clue where it's wrong. PPTP can connect but IPSec connection would just keep sending Accounting-Request and never connects (it looks like connection depends on this step). The obvious consequence of this is that there is no accounting info in the DB (due to above warning). I did have success when configuring both separately before. When I combine both together it seems to always cause issue. I am sure it's a configuration issue but I just can't see where the problem is. I saw a post related to this before but it had no resolution other than telling OP that his configuration was wrong. One hint I have is the following log but I don't know what's the cause of it. ignoring request with ID <id>, already processing retransmitting RADIUS message ... #goes on for a while for IPSec, only twice for PPTP RADIUS is not responding Thanks
