Cannot reach tunnel endpoint
![[us]](/s/countries/us.gif) Shadow Hawkins on Saturday, 08 October 2011 18:46:01
I cannot reach the remote endpoint of my tunnel. On Saturday at 12:00 by the Tunnel Statistics graphs, there was an odd spike in latency, packets/s, and octets/s. Now the tunnel seems to be dead: as far as I can tell, it gets set up correctly and simply won't accept traffic.

Same problem and behavior here as well with my tunnel(T72929). It was working fine last night, now it reports that it is connected but not passing traffic.

Thanks for reporting, all should work fine again.

This issue appears to have reoccurred as of an hour ago. I do not have physical access to the end-point machine at this time, but the tunnel statistics graphs appear similar to the first occurrence.

This issue seems to have occurred once again. Was the previous occurrence silently resolved, or did it eventually resolve itself?

You will really have to describe what exact problem is occurring and provide details of that problem along with the information requested.
