    Hello guys! I'm new here... never thought that one day I'm going to register here...

    Anyway, I have a problem... I have Two routers one is Main Router/Modem other is second router for wi-fi (since main router accidently lost it's antenna) so let's see:

    1st Main Router (Pirelli DRG - A125G)
    2nd Router (TP-Link TL-WR740n)

    My Computer is connected to 2nd router so I get like this : Computer -> 2nd R -> 1st Main R -> Internet.
    Internet is working with no problems at all... But since last week I have to use some Ports... like three of them. This was my first time I ever experienced port opening (or forwarding) issues... I never thought I could be pain in the ***...

    to Shorten you answers to most correct ones I'll describe what settings are used now, and still no port forwarding...

    My PC IP:
    Ipconfig says:

    IPv4 Address. . . . . . . . . . . : 192.168.0.100 THIS ONE RIGHT?
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.0.1


    My 2nd Router IP:
    Wan: (not sure what that means anyway)
    IP Address: 192.168.1.100 Dynamic IP
    Subnet Mask: 255.255.255.0
    Default Gateway: 192.168.1.254
    DNS Server: 192.168.1.254 , 0.0.0.0


    Lan:
    IP Address: 192.168.0.1
    Subnet Mask: 255.255.255.0


    My 1St Main Router IP:
    and... erm... I cannot find all these ips.... way more confusing interface than TP-Links...
    so thats where my knowledge ends... :(
    anyway as you can see from 2nd routers default gateway that my Main router's IP is 192.168.1.254.

    So... Can anyone help me to fix this problem.?

    BTW: Port forwarding should go like this? Main router should forward to second router, and second router should forward to my pc?

I can see my PC's IP from MAIN ROUTER, and secondary router is used i dunno like a Switch i guess... thats a good I guess.... but stilll Ports are closed :( I found a guide on internet for my DRG -A125G Port forwarding, did same... but still no ports are opened.

    yes, if configured as in johnwills post

    this is useful to check ports
    http://www.t1shopper.com/tools/port-scan/


    can we have all the IPS again - the 2nd router dhcp should be OFF -
    as now they should be setup differently

    I turned off DHCP on second router before, and there is no second router at all in my network places. but my wi fi laptop is logged in on second routers based connection... so anyway everythings good but ports



    Maybe problem is in my WIndows 8? or Antivirus? I tried to turn off both of them... still no luck

    Are those address are correct for the first router given out an IP address - whats the range of the first routers DHCP

    I would set a fixed IP address on the devices you are port forwarding to in the router

    is this confusing the situation at all ?

    What IP did you set the 2nd router to ?

    i would use anything between 192.168.1.2 and 63

    and then on the first router port forward the ports you want to the IP you choose

    its not showing a fixed IP address - which would be better fro port forward - its showing an IP in the range DHCP range of
    192.168.1.64 - 192.168.1.220 and dhcp is enabled on the ethernet adapter
    you need to set to a fixed IP between i would use anything between 192.168.1.2 and 63 and then port forward to that IP

    are you OK to set a fixed IP address

    im Using Windows 8 Pro

    quick edit: when I Setup a fixed IP. I got disconnected from the internet and getting Unidentified Network... I ues 192.168.1.60 as a fixed ip.

    Quick edit 2: When i try to troubleshoot this network, i get this problem fixed by Enabling DHCP again. and no fixed ip
