Hi Everyone,

Please can someone help.  I'm trying to setup some port forwarding and I have both a Dlink DIR-855 and a Dlink DSL-2680 Modem.

I'm trying to just open port 5000 and have confirmed that my ISP is not blocking it, yet no matter what I do, I can't get it to open.

I understand HOW to open ports and even bought the PF Config software, but it still won't open and I'm sue it's something to do with the fact that I have both a router and a modem, both of which seem capable of opening ports.

Can anyone tell me what I am supposed to do when using both? 

I've been trying to do this for WEEKS, so if anyone can help, I would be soooooooooooo grateful!!!

Thanks so much for reading.

Frank

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?
• If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address 192.168.0.1. Check to see if this is the same on the ISP modem and if modem can't be bridged. If so, change the DIR router to 192.168.1.1 or .0.254.

As FurryNutz suggested, bridging is a good option.

Alternatively, what you'd need to do is go into the modem configuration and forward port 5000 to the whatever IP address the modem has assigned the router (and it's best if the router's IP is set up as static in the modem settings), then in the router configuration you forward port 5000 to the IP address of the device (again, best if it's assigned a static IP).

So - request for port 5000 comes in from the Internet and hits the modem.
The modem directs it to the router, and then the router directs it to the device.

Thanks so much for this, I'm away from home until Saturday 15th, so will check all this when I get back, but just wanted to say thank you in the meantime.

Thanks

Let us know how it goes...

Thanks for your help, as mentioned I was away, so just picking this up now... please could you see below for my answers....

Thank you so much

  Attached is a screenshot from the router, it was not on a 192.168.0 ip but instead a 192.168.1.2

  Modem didn't appear to be conflicting with the router IP address, but I'm confused about whether not it is bridged.  It seems to mention some bridging on the dropdown of the screen grab of it's settings see below

You need to bridge the ISP modem before you can correctly port forward. Having two routers online at the same time will prevent successful port forwarding on the 855 router.

[bigfrank]

Ok, thank you.  Do you have any idea how to bridge the modem?  I'm a bit confused how to adjust the settings to do this...?

Thanks

Do a web search or contact your ISP for help and information regarding bridging the modem...
