I'm having the same issue with my production environment using only PPTP for
the tunnels. Odd thing is that when the tunnel goes down - both ISA's and the
clients behind them can still get out on the internet yet both ISA's report
that the other's endpoint is unreachable and event log reports that there's no
answer.
I have both RRAS demand dial interfaces set to persistant.
I passed the problem off as a DHCP issue because at the times the tunnel would
go down I would see event logs on my dhcp servers talking about DHCP db cleanup
taking place. I changed both tunnel endpoints to use a static IP but the
problem still occured...*shurg*

Hi Glenn,
Does the tunnel reconnect if a client behind the ISA Server makes a request?
Thanks!

Am I missing something here, I must be, I have 2 ISA servers that I have setup
for a test environment, currently I am working with VPN tunnels, both PPTP and
L2TP, my problem is this, after establishing a tunnel, either PPTP or L2TP
after short period of time the tunnel disconnects and no mater what I do I can
not reestablish the link. Both of these ISA servers were built as standalone
integrated web cache, firewall and proxy. I did install the Certificate service
on one of the ISA servers, keeping in mind this is only to evaluate the ISA
platform. My remote ISA server that ran Remote VPN wizard and read the config
file also requested and installed a Cert from the Cert server? There must be a
way to build either a PPTP or L2TP tunnel and have it enabled and always
connected. What am I missing here?
Thank you
Glenn
