Virtual Private Networking Using SSL Connections

ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
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
includes the following addresses: 10.0.0.5–10.0.0.20 and the FQDN ftp.company.com,
which resolves to 10.0.1.3.
Assuming that no conflicting user or group policies have been configured, if a user would
attempt to access:
an FTP server at 10.0.0.1, the user would be blocked by Policy 1.
an FTP server at 10.0.1.5, the user would be blocked by Policy 2.
an FTP server at 10.0.0.10, the user would be granted access by Policy 3. The IP
address range 10.0.0.5–10.0.0.20 is more specific than the IP address range that is
defined in Policy 1.
an FTP server at ftp.company.com, the user would be granted access by Policy 3. A
single host name is more specific than the IP address range that is configured in Policy 2
Note: The user would not be able to access ftp.company.com using its IP
address 10.0.1.3. The VPN firewall’s policy engine does not perform
reverse DNS lookups.
