VPN to Cisco Drop out was created by baileyphil
Hi Guys was wondering if somebody could help me please, i have a Vigor 2860 router setup with a VPN to a datacenter cisco router, the VPN seems to drop out after 20ish mins then reconnect, not sure what is going on.

Ive put the syslog from the router below, any help appreciated, the first line is were the VPN reconnects and we gain access, we lost connection at the bottom of this post.
