I just installed a second 1721 router at a remote site and it connects to HQ
via IPSec VPN. Works Great when I have a laptop there on site and its
actively communicating back to the HQ Subnet. There is only one device
there at the remote location and its just a web server of sorts, so it only
talks when its spoken to.
My problem is that since the remote site is on DSL, the VPN drops here and
there. Since the only device at the remote location does not talk unless
spoken to, it never tries to bring up the VPN connection.
Is there a way to make the router keep the VPN connection up even if there
is no traffic destined to the remote network?
The DSL Service is a Dynamic IP, so I can have HQ bring up the connection to
the remote. I was hoping for some keep-alive that I can set up in the
router to ping the HQ subnet every once in a while.
