ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
Create LAN WAN Inbound Service Rules
The Inbound Services table lists all existing rules for inbound traffic. If you have not defined
any rules, no rules are listed. By default, all inbound traffic (from the Internet to the LAN) is
blocked. Remember that allowing inbound services opens potential security holes in your
firewall. Enable only those ports that are necessary for your network.
WARNING:
Make sure that you understand the consequences of a LAN WAN
inbound rule before you apply the rule. Incorrect configuration
might cause serious connection problems. If you are configuring
the wireless VPN firewall from a remote connection, you might be
locked out.
