I'm trying to run a pptp link to secure the wireless traffic between my FreeBSD server/firewall and a win98 machine. I'm using 2 D-Link 520. The D-Link in the FreeBSD server is running in Host-AP mode. The wireless link itself works fine. The problem is that whenever I download a file to the win98 machine the pptp connection randomly freezes after a few megabytes and I get the message below in /var/log/messages. The number is always around 4000. After this I have to reconnect to continue. I have tried 40 and 128 bit encryption with the same result.

Does this mean that mppc got fed an old packet? /kernel: ng_mppc_decompress: insane jump 4089: (1690-1697) & 0xfff On a related issue, there is a new l2tp netgraph module. Is there any work in progress to, for example, extend mpd to be able to act as a l2tp server? -- Mikael Hubsch Email: Mikael.Hubsch@tfstech.com TFS Technology AB Phone: +46-8-7259730 Box 10020 Fax: +46-8-6494970 S-121 26 STOCKHOLM, SWEDEN To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
