WR1500 Wireless Router has to offer. For this reason, it is recommended that you confi gure
your fi rewall using the Web Confi guration Utility. SMT screens allow you to activate the fi rewall.
12.2 Firewall Policies Overview
Firewall rules are grouped based on the direction of travel of packets to which they apply:
• LAN to LAN/WR1500 Wireless Router
• WAN to LAN
• LAN to WAN
• WAN to WAN/WR1500 Wireless Router
By default, the WR1500 Wireless Router’s stateful packet inspection allows packets traveling in
the following directions:
• LAN to LAN/WR1500 Wireless Router
This allows computers on the LAN to manage the WR1500 Wireless Router and communicate
between networks or subnets connected to the LAN interface.
• LAN to WAN
By default, the WR1500 Wireless Router’s stateful packet inspection blocks packets traveling in
the following directions:
• WAN to LAN
• WAN to WAN/WR1500 Wireless Router
This prevents computers on the WAN from using the WR1500 Wireless Router as a gateway
to communicate with other computers on the WAN and/or managing the WR1500 Wireless
Router.
You may defi ne additional rules and sets or modify existing ones but please exercise extreme
caution in doing so.
