HELP: How do i pass through public IP's from dialer interface to physical interface without NAT?
I'm having alot of trouble trying to do something reasonably straight forward, or so i thought. I have been given a /29 ip block by my ISP, im using a Cisco 2811 router with an ADSL HWIC. If i set the dialer interface to "ip address negotiated" it works fine, but i want to put that ip block directly on the inside interface so i don't have to use NAT overload or static 121 NAT.
I have tried putting my block of IPs on Gi0/1 and removing "ip address negotiated" from the dialer interface and replacing it with "ip unnumbered GI0/1" thinking it would force the dialer interface to take the ip from the GI0/1 instead. However i just cant get out to the internet when i do this.
Am i missing any commands or am i doing it wrong? I have googled this o nthe web but can't seem to find the answer which is odd, everybody uses NAT instead.
Passing through a public block from an ISP to a physical interface shouldn't be too difficult surely?
Can anyone crack this for me?
Just as an extra note i found this article which is similar to what i want to do but uses a vlan interface (because its a 887 and has switchports for access)
