I updated my box to 4.008 a couple days ago and now PPTP is broken. I'm using RADIUS authentication with Microsoft IAS. Below is a log of one of the connection attempts. There appears to be some sort of DNS problem and then an authentiaction failure. When I look at the log on the IAS server, however, I never even see an attempt to authenticate. Everything worked before the update. Any ideas?
