Can I route based on subnet and port?

[jason305]

We've recently added a frame relay line to a business partner, but now we are unable to access thier website. They use private IPs, but we use real world. I have to assume that we can't get the pages because we're going out over our ISP, but the response is coming back over FR.

Does this sounds about right?

What I'd like to do is add a route on their end which would send all port 80 traffic to thier ISP, but everything else goes over the frame. Good idea / bad idea? If so, how do I do it? Easier way?

If your trying to access there website via the internet it should return back to you over the internet. Do a trace route to the url to determine the path. ( WOW ) Where is there website ? through there isp or on site ? Jeter@LasVegas.com The best answer I could ever give is the one to maintain my Sanity

Hmmm.. just off the top of my head, I would guess your DNS is resolving everything as a "real" IP. Since they are private.. it wont show in your gateway/proxy etc. What I *might* suggest is to put NAT on the port.. add a static translation for port 80 to the correct private IP for the web server.. give the port a "real" IP address you own and then add that server's name with your "real" IP you gave the port as the servers IP. NAT will pick it up, translate it to the private as long as it's port 80.

I think I have it right with the ASCII art ;-)
