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.
