Hi, I've been looking at the L2TP server support in FreeBSD. So far, I've found the following: sl2tps mpd + some patch - L2TP patch documented in German l2tpd - marked as broken Given that the mpd patch was not in ports, and was only documented in German, and that l2tpd was marked broken, I though I would try sl2tps. However, when trying to connect from l2tpd on Linux, the FreeBSD box logs the following and rejects the attempt: "processing failed on mandatory AVP" After a few attempts, the sl2tps process stops responding to any L2TP packets. Even killing the process and starting it again doesn't help - I have to completely reboot the FreeBSD box, which suggests there is a fault in the kernel code. Can someone please advise the preferred way of running a stable L2TP server on FreeBSD? Which version of FreeBSD and which daemon? We are aiming to terminate 100+ concurrent tunnels from a variety of client devices.
