NAT in Cisco 3750 Switch

Unanswered Question
Apr 9th, 2008

Hi,

I have a peculiar question.That,I have Cisco3750 switch,in which I have created 3 VLANs,named VLAN10,VLAN20 and VLAN 30

Thne in VLAN 10,I have a server with the static IP address in that VLAN subnet,then I have configured VLAN interface 10,20 and 30 for inter VLAN communication.(By enabling the IP routing)

My requirement is the server which is in VLAN 10 has to be natted to VLAN 20 and VLAN 30 Is it possible?Basically a static NATTING.....

Please hep me.

My guess: Basically a VLAN interface is a virtual,it is not a physical,in that case static natting may not be possible.

If it is a physical port,atleast we could convert it as a ROUTED PORT,then atleast we can use the IP NAT inside etc...

Thanks and Regards,

S.Venkataraman.

I have this problem too.

Sorry, Cisco 3750 switches doesn’t support NAT

at all, and is no planning for NAT support.
