13.3 NAT Address Mapping
Click ADVANCED > NAT > Address Mapping to open the following screen.
Ordering your rules is important because the LAN-Cell applies the rules in the order that you
specify. When a rule matches the current packet, the LAN-Cell takes the corresponding action
and the remaining rules are ignored. If there are any empty rules before your new configured
rule, your configured rule will be pushed up by that number of empty rules. For example, if
you have already configured rules 1 to 6 in your current set and now you configure rule
number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if you delete rule
4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become new rules 4, 5 and 6.
Port Forwarding
Rules
The bar displays how many of the LAN-Cell's possible port forwarding rules are
configured. The first number shows how many port forwarding rules are configured
on the LAN-Cell. The second number shows the maximum number of port
forwarding rules that can be configured on the LAN-Cell.
Port Triggering
Rules
The bar displays how many of the LAN-Cell's possible trigger port rules are
configured. The first number shows how many trigger port rules are configured on
the LAN-Cell. The second number shows the maximum number of trigger port rules
that can be configured on the LAN-Cell.
Copy to Cellular
(and Copy to
WAN)
Click Copy to Cellular (or Copy to WAN) to duplicate this WAN interface's NAT
port forwarding or trigger port rules on the other WAN interface.
Note: Using the copy button overwrites the other WAN interface's
existing rules.
The copy button is best suited for initial NAT configuration where you have
configured NAT port forwarding or trigger port rules for one interface and want to
use similar rules for the other WAN interface. You can use the other NAT screens to
edit the NAT rules after you copy them from one WAN interface to the other.
Apply Click Apply to save your changes back to the LAN-Cell.
Reset Click Reset to begin configuring this screen afresh.
