Setting Nat Rules; Static; Dynamic; Managing Dynamic Bindings - Cabletron Systems IA1100 User's Reference Manual

Setting NAT Rules

Static

You create NAT static bindings by entering the following command in Configure mode:
Enable NAT with static address
binding.

Dynamic

You create NAT dynamic bindings by entering the following command in Configure
mode:
Enable NAT with dynamic
address binding.
For dynamic address bindings, you define the address pools with previously created
ACLs. You can also specify the enable-port-overload parameter to allow PAT.

Managing Dynamic Bindings

As mentioned previously, dynamic address bindings expire only after a period of non-use
or when they are manually deleted. The default timeout for dynamic address bindings is
1440 minutes (24 hours). You can manually delete dynamic address bindings for a specific
address pool or delete all dynamic address bindings.
To set the timeout for dynamic address bindings, enter the following command in
Configure mode:
Set timeout for dynamic address
bindings.
To flush dynamic address bindings, enter the following command in Enable mode:
Flush dynamic address bindings.
