I want to assign ports to LAN attached devices. I don't want to forward ports. I just want to assign ports to particular IP address for LAN devices. How?
I second this; it's a feature I had on an old Billion modem+router, and its version of QoS let you assign priorities to each of the four RJ45 ethernet jacks on the back. We had ours set up so that the download-box was on port 4 with the lowest priority, but full accessand no speed restrictions otherwise. Soon as one of the other machines on the LAN accesed the internet, the download box got instantly throttled, no matter what traffic nor protocol it was. Soon as our web page had loaded or Flash movie finished buffering, the download box got all the bandwidth again. Never seen anything like it before, or since.
I'm not sure I've understood the question, but it sounds like something you achieve with vlans. Look into the vlan config page and tag traffic on a port basis.
I was thinking of any thing that fancy. On my cheap but old now dlink you can put port numbers in the fields of the static ip's. Simple, easy. I tried adding port number to the ip address line of the dhcp assigned/static dhcp field and the :80 (as an example) took. So the line read 192.168.1.1:80. But I have no idea IF that assigned that IP address to port 80.
This site allows you to click on the various headings for setting up a Linksys router. This kind of thing is what I was talking about. Especially on UPNP forwarding. http://ui.linksys.com/files/WRT54GX/v1/1.02.10/UPNP_Forward.htm
