To view the ARP table for the LAN port, enter ip arp status enif0.
Each ZyWALL can support a specific number of NAT sessions in total. You can limit the
number of NAT sessions allowed per host by using the ip nat session command. In the
following example, each host may have up to 4000 NAT sessions open at one time. The total
number of NAT sessions must not exceed the number for your ZyWALL.
To see the IP routing table, enter the following command.
