GRE keep alive, connection drops once a week.
-
Does anybody know of a way to enable keep alive on GRE. My GRE connections turn off about once a week for unknown reasons, and I have to restart the IPsec service to get them to turn back on.
I am connecting to Verizon, thru a IPsec transport , they have Cisco equipment on the other side. they say I am showing carrier transition errors. On that note I unaware of any GRE diagnostic tools.
I did have to increase net.link.gre.max_nesting in the system tunables to make the connection work in the first place.
any ideas would be appreciated.
thank you.

Under diagnostics, and PFinfo I noticed some packets are getting blocked, not sure what to do with that info, or if it is relevant.
