Currently I can perform single and ranged port forwarding on my modem/router. However, I can only set it to forward all requests of a specific port to one destination IP address. I want to be able to specify the destination IP address based on also the destination name and port.
So, for example, a request on port 80 for domain1.com would go to one IP address on my LAN, whereas a request on port 80 for domain2.com would go to a different IP address. Same for SMTP, so domain1.com on port 25 would go to one IP address, and domain2.com on port 25 would go to a different IP address.
I can do this very easily with ISA and my current router, but I don't really want to leave another computer on all the time if I can replace my current modem/router with another modem/router will do what I want.
Is there any equipment out there that will do this for me?

Hi,

A Cisco router may be able to do it, worth checking into it. Not sure as I've never actually used one, but it's the most likely.

A vigor router should do this and be cheaper then a cisco router.

I have used them in the past and are excellent products.

ps I am not linked in any to router apart from buying them
