NAT. It also allows all ICMP packets go through IP NAT.

To do this, use the command:

enable ip nat bypasstcp

When bypasstcp is enabled, IP NAT performs IP address and port translation for

TCP packets and forwards the packets, regardless of the TCP sequence number

and the current TCP state. It also allows ICMP echo reply and other ICMP packets

to initiate a session and get forwarded.

To disable the bypassing, use the command:

disable ip nat bypasstcp

Bypassing is disabled by default because it degrades the security of IP NAT.

However, it is useful when you need NAT on VRRP routers.

Note that this enhancement does not apply to firewall NAT.
