NATing on Cisco 6500 switch

Hi All -

Scenario - I have a source machine with IP 10.1.1.1 with a specific application running on that and that machine will be communicating to destination host on the different Vlan. Lets say IP 10.2.1.1

Applications on both machines communicates bidirectional with the UDP port number 3700

Requirement

--

Port number which is generated by application on 10.1.1.1 need to be translated to port number 7001 and should be handed over to 10.2.1.1 and the response which sent from 10.1.1.2 once again need to be converted back to 3700 and sent to 10.1.1.1

Please let me know how do I do this (Will be of great help if you let me know the command instructions as well)

( Ps.I have a Cisco 6500 switch on which both Vlan's are created )

Thank you

Shash

Re: NATing on Cisco 6500 switch

Hello Shash,

you need to use a protocol port specific NAT

example:

ip nat inside source static udp 10.1.1.1 3700 10.2.1.1 7001

Hope to help

Giuseppe
