Changing IPSec policy order
WatchGuard handles policies in the order listed, from top to bottom, on the IPSec
configuration dialog box. Initially, the policies are listed in the order created. You
must manually reorder the policies from more specific to less specific to ensure that
sensitive connections are routed along the higher-security tunnels. In general,
WatchGuard recommends the following policy order:
• Host to host
• Host to network
• Network to host
• Network to network
Policies must be set to the same order at both ends of the tunnel. For more
information about IPSec policy order, see the
Network Security Handbook
.
From the
IPSec Configuration
dialog box:
• To move a policy up in the list, click the policy. Click
Move Up

• To move a policy down in the list, click the policy. Click
Move Down

Configuring services for branch office VPN with IPSec
Users on the remote Firebox are technically outside the trusted network; you must
therefore configure the Firebox to allow traffic through the VPN connection. A quick
method is to create a host alias corresponding to the VPN remote networks and hosts.
Then, use either the host alias or individually enter the remote VPN networks and
hosts when configuring the following service properties:
Incoming
• Enabled and Allowed
• From: Remote VPN network, hosts, or host alias
• To: trusted or selected hosts
Outgoing
• Enabled and Allowed
• From: trusted network or selected hosts
• To: Remote VPN network, hosts, or host alias
For more information, see “Defining service properties” on page 49, and “Adding a
host alias” on page 86.
