Not SNAT base on destination port.

the F5 is configure with SNAT. Is it possible to use the Iruless to tell F5 not to SNAT base on the Destination port?

 

For example:

 

If the client try to send a TCP packet with destination port 1801. The F5 should not SNAT the source IP address of the client, It should forward the packet using the the Source IP address of the client and not the IP address of the F5.

 

Thanks

    The command you're looking for is the snat command - Click here

     

     

    You could simply say "snat none" when you find the clients connecting to the given TCP destination. That should bypass the configured snat on the system.
