Port assignments on the security gateway let you specify if the LAN port resides
on a trusted or untrusted network. Trusted ports are for networks not using
VPN authentication to connect to the LAN. Untrusted ports are for wireless or
wired networks using VPN clients to connect to LAN resources.
You can connect many network devices to the LAN ports: routers, switches,
client machines, or other Symantec Gateway Security 300 Series appliances. For
these options, select the Standard port assignment. If you are connecting a
Symantec Gateway Security 300 Series appliances configured as a wireless
access point to a LAN port, you can secure the wireless connection using VPN
technology. See the Symantec Gateway Security 300 Series Wireless
Implementation Guide.
Once a port assignment is set, the untrusted ports enable and enforce encrypted
VPN traffic, using global tunnels to the appliance or using IPsec pass-thru to
WAN-side endpoints.
