Hi!
My situation is following:
I have 2 routers, for connection to internet each router establish pptp connection. Then one router connect by pptp to second router. first router configured with pptp-server interface, secont router configured with pptp-client interface. all works fine, but internet provider force drop internet vpn connection time-to-time. internet connection on all routers automaticaly established, pptp interfaces for routing between two routers in running state but routing not work before i manually reset them.
Defines the time period (in seconds) after which the router is starting to send keepalive packets every second. If no traffic and no keepalive responses has came for that period of time (i.e. 2 * keepalive-timeout), not responding client is proclaimed disconnected
