I've got a Mac dialing into a windows VPN and all works fine but it disconnects randomly. I setup a cronjob to load an URL as detailed here to check for a connection. If there's none, it restarts the connection. I keep track of how often it does this and its way too common. The script checks for a connection (and thus makes activity) every 5 mins so there shouldnt be a timeout.

Here's what my logs say

Feb  4 04:45:06 macnerd pppd[1708]: Terminating on signal 15.
Feb  4 04:45:06 macnerd pppd[1708]: MPPE disabled

The VPN Server is Windows based and it doesnt disconnect my XP clients. Here's the "pattern" of droppage.

Feb 4 04:45:06 macnerd pppd[1708]: Connect time 165.0 minutes.
Feb 4 06:10:06 macnerd pppd[2246]: Connect time 80.0 minutes.
Feb 4 07:35:09 macnerd pppd[2497]: Connect time 80.0 minutes.
Feb 4 08:47:55 macnerd pppd[2747]: Connect time 67.8 minutes.


Oh, also, sometimes when I connect 2 machines on the network, the Mac drops its connection:
64 bytes from 10.0.0.100: icmp_seq=14 ttl=128 time=11.226 ms
ping: sendto: No buffer space available

Any insight would be super, thanks!
