CR00016758 | IP NAT | - | This enhancement enables you to turn off TCP state and sequence checking in IP | Y | Y | Y |
| - | - | - |
| - | - | - | - |
|
|
| 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. |

|
| interfaces.This assists with wireless station roaming. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| To enable this feature, use the command: |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| enable ip arp silentroam |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| To disable it, use the command: |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| disable ip arp silentroam |
