I have a customer that has been allocated an IP range by the ISP.
220.127.116.11/29 for example.
The Cisco router gets its IP of 110.x.x.x which is fine, and I can add a sub-interface with an IP in that 18.104.22.168 range and am able to ping that.
However the problem is that I need the router to be connecting to the internet but my firewall using the IP's in that public ip range as well as doing all the port forwarding. We have this same configuration working with other customers, only in those scenarios the router is a Cisco 877 and is managed by the ISP.
Is what I am describing possible with the SRP 527?
Any suggestions would be great!
