Without getting too much into the specifics of the setup, has anyone
had this issue?
I have a routed Site-to-site VPN link between 2 2003 servers using
RRAS, i use PPTP for the tunneling protocol. there is no NAT involved
as both routers have public addresses. the virtual interfaces on the
routers are set to DHCP. i have set the demand dial interfaces to
"persistent" connection etc... this works fine, the Demand dial
connections will dial each other and i can pass traffic across this
VPN no problem. Now, i am not being ironic by telling you guys that
something actually works on a help group, i do actually have a
problem. if the link is open for a period greater than 12 hours all
communication ceases, disconnect and then re-dail the connection, and
it functions again. why? that is my question.
