NAT 6500 SVI

[john.pepper]

Hi,

I've configured NAT on routers using physical interfaces.  And also on a 6500 (Sup720) using a combination of SVI (Inside) and a physical interface (Outside) for the NAT interfaces.

But I seem to remember there was a problem when trying to do NAT using 2 x SVI's - i.e. one being Inside and the other being Outside.

Has anyone done this?

Thanks

Hello,

that should be possible. Check the section 'Catalyst 6500 in Hybrid Mode Configurations on the Supervisor (Switch Processor)' in the document linked below:

Thanks for the reply.
I have looked at this doc before. And pretty sure I tried to implement that Hybrid version, but on a newer Sup. And it didn't work for some reason. Ended up using a router hanging off the 6500.

But I'll try again see if successful.

Thanks
