Hey guys. I am in need of some help. I have a VPN tunnel that is up and running. Periodically / Randomly I get disconnected and when I look at SYSLOG, this is what I find.

What I am attempting to determine is if this is a problem on my end or the other end.

"LCP terminated by peer" would indicate to me that I was disconnected on their end. Is that true? If so, what would cause this. The tunnel has been up and running for a few days now and this just happened.


Any information you could give me would be greatly appreciated.


Thanks,


-G

Yes.

A lot of things. Excessive packet loss, maximum connect time reached...

17999.9 minutes does not look random, so I guess you reached the maximum
connect time. If you want the VPN to be reopened automatically, consider
adding "persist" to the corresponding pppd options file.
