IP unnumbered and NAT question

Hi,

I have a 2600 router with 4 BRI's and an ethernet. I configured a dialer interface and rotary group for the BRI's.

I have a valid IP address on my ethernet port.

I've configured dialer interface for "ip unnumbered fastethernet 0/0"

I've configured the router to run DHCP and serve bogus addresses to hosts.

I've configured NAT and have it "overloading" on the address of the fastethernet port.

I haven't been able to test the configuration yet, but am wondering if this is a legal configuration. I got no errors rom router.

Will this configuration work, having the Dialer interface, ethernet interface, and NAT using the same address at same time?

Thanks - Barry

Re: IP unnumbered and NAT question

yes, it will work.

Same address but different port numbers.

The router will map each port to a different ip address/port.
