Configuring Advanced Subnet Access
Use the Advanced Subnet Access screen to configure complex access rules and filtering based on
source port, destination port, and transport protocol. To enable advanced subnet access, the
subnet access rules must be overridden. However, the Advanced Subnet Access screen allows you
to import existing subnet access rules into the advanced subnet access rules.
To configure Mobility 7131 Access Point Advanced Subnet Access:
1. Select Network Configuration -> Firewall -> Advanced Subnet Access from the Mobility 7131
Access Point menu tree.
2. Configure the Settings field as needed to override the settings in the Subnet Access screen
and import firewall rules into the Advanced Subnet Access screen.

Subnet Access Select this checkbox to import existing access rules (NAT, packet forwarding, VPN rules
etc.) into the
Firewall Rules field. This rule import overrides any existing rules configured
in the Advanced Subnet Access screen. A warning box displays stating the operation
cannot be undone.
