Important
When you create a remote site network that uses the Internet
Protocol security (IPsec) tunneling protocol, the Microsoft
Firewall service modifies the IPsec filters on the computer, when
restarting the Firewall service. This process can take up to
several minutes, depending on the number of subnets included in the
address ranges for the network. To minimize the effect, we
recommend that you define IP address ranges that are aligned in
subnet boundaries.
If you stop or restart the IPsec PolicyAgent service, all
dynamic IPsec configuration information is lost, including ISA
Server VPN site-to-site IPsec configuration settings, and VPN
clients are disconnected. To restore settings, start the
PolicyAgent service or restart the Firewall service.
A remote site network cannot share the same IP addresses as one
of your other networks.
