fowarding ports

[ezkim0x]

modem/router combo -> buffalo wireless router -> switch -> cp1 , cp2

so I have 2 machines.. one is a fileserver (cp2) that I connect to through remote desktop on my main computer (cp1)

on my modem/router combo I set DMZ to the buffalo's WAN IP .. 192.168.254.1

I was able to type this IP into explorer and it would log into the buffalo router..

then I fowarded a port in the buffalo router for cp1 (192.168.10.110) and had windows firewall turned off on both machines.

I used a port checker online to see if my port was open and it was on pc1..

I tried to foward another port using the firewalls ip (192.168.10.112) ..but it says the port is closed when I try to use the port checker on there through remote desktop

is it doing this because I'm connected to my main computer.. and actually checking from .110 ? ..or should it still show if the port is open/closed on .112?

if it should show then I can't get the port opened on the fileserver for some reason.. and I've made sure windows firewall is off and all taht.

..secondly..

now when I type my WAN IP for the buffalo router in explorer it goes to a page cannot be displayed.. and I looked under Status -> sys-info and it still says the WAN IP is the same.. so I don't get it.

WAN IP
192.168.254.1
LAN IP
192.168.10.1


also I tried pinging the wan ip with angry ip scanner and it responds to that as well.. and now it says the port is closed on my pc1 too.. since it's not resolving the wan ip to goto the buffalo router for DMZ

why setup this way? Double NAT routing gets ugly quick. Most modem/router's have a passthrough/bridge mode to disable the NAT router in the combo unit.

didn't know there was another way.

how do I disable it?
