Add an IPv4 or IPv6 SSL VPN Policy
You can define and apply user, group, and global policies to predefined network resource
objects, IP addresses, address ranges, or all IP addresses, and to different SSL VPN
services. A specific hierarchy is invoked over which policies take precedence. The VPN
firewall policy hierarchy is defined as follows:
User policies take precedence over group policies.
Group policies take precedence over global policies.
If two or more user, group, or global policies are configured, the
most specific
policy takes
precedence.
For example, a policy that is configured for a single IP address takes precedence over a
policy that is configured for a range of addresses. And a policy that applies to a range of IP
addresses takes precedence over a policy that is applied to all IP addresses. If two or more
IP address ranges are configured, the smallest address range takes precedence. Host
names are treated the same as individual IP addresses.
Network resources are prioritized just like other address ranges. However, the prioritization is
based on the individual address or address range, not the entire network resource.
For example, assume the following global policy configuration:
Policy 1. A Deny rule has been configured to block all services to the IP address range
10.0.0.0–10.0.0.255.
Policy 2. A Deny rule has been configured to block FTP access to 10.0.1.2–10.0.1.10.
Policy 3. A Permit rule has been configured to allow FTP access to the predefined
network resource with the name FTP Servers. The FTP Servers network resource

Assuming that no conflicting user or group policies have been configured, if a user attempted
to access FTP servers at the following addresses, the actions listed would occur:
10.0.0.1. The user would be blocked by Policy 1.
10.0.1.5. The user would be blocked by Policy 2.
