There is a machine on my lan with IP 10.10.10.2
Apache installed on that host is configured to serve several named virtual hosts: www.domain a...b...c.com
While I was using a cheap SMC router, I could type www.domaina.com in a browser on another machine on the LAN and access 10.10.10.2, which would serve the correct web server.
Now that I am on 877 it allows only the users from the WAN to access the named virtual hosts. I can't access them from inside the network, and I can't cheat on Apache side and create copies of the name virtual hosts as virtual hosts on another port, because the servers I am using embed full domain name in all the links, so I am getting only as far as the home page w/o any graphics and with no ability to follow links.
Basically, I can set up a copy of virtual host www.domaina.com as 10.10.10.2:8080, but when I type that address in the browser, all the links on the home page still say http://www.domaina.com/link1 etc.
So I have to set something up on 877 router to replicate the functionality of my old SMC VBR7004.
Hoping I am making sense, please feel free to ask if something is not clear.
