secondary ethernet address and nat

[csross]

I have a 2611 and need more ethernet interfaces. I want to add a secondary address to one of the interfaces but may have to use nat as well. Only one of the addresses need to be natted? Is this possible and if so, how?

Thanks

Just add the IP address to the static nat statement and you are done. You might have to add a routing statement for that network out the inbound interface, but probably not (it's been a while since I have done this). As long as the upstream router (typically this ISP) is routing the subnet down the interface (typically the WAN aka serial interface), that is all you need. You probably don't need a new routing statement as long as your router has a default route. Remeber these are router and are designed to route packets.

Once again, I don't have your config here, but it will work.


It is what it is!!
