NAT on 1 ethernet

[UNIX72]

I need to provide nat for 2 Class addresses that our hard coded on the board to a 10.x.x.x. The problem is i only have 1 ethernet port on my 2611 router. Is it possible to provide nat between a secondary interface with a primary interface on the same ethernet port? I want to created a secondary subnet which will be 192.x.x.x and then do nat. Is this possible? Can anyone post a sample config, thanks.

Yes NAT will work with secondary addresses on the inside and there should not be anything complex to configure here as you will configure the NAT access-list to allow just the primary or secondary or both to pass through the NAT.

Example:

ip nat inside source list 1 interface serial0 overload

interface serial0
ip address XXX.XXX.XXX.XXX SSS.SSS.SSS.SSS
ip nat outisde

interface ethernet0
ip address AAA.AAA.AAA.AAA SSS.SSS.SSS.SSS
ip address AAA.AAA.AAA.AAA SSS.SSS.SSS.SSS secondary
ip nat inside

access-list 1 permit AAA.AAA.AAA.AAA SSS.SSS.SSS.SSS (this is the newtork address range that you would to be able to pass through NAT)


Hope this helps.
