Help! Why Can't I Forward Ports On Dlink Dir-855?
« on: February 22, 2014, 01:20:49 AM »

Hi everyone, I'm hoping someone can help here. I'm basically trying to open port 5000 on my router so that i can remotely access my Synology DS214play Nas.  Here is a screenshot of how I've opened port 5000 yet when I check this port it's showing as closed and I can't access the NAS.

https://www.evernote.com/shard/s58/sh/e6a9dd9b-6a75-446f-aaa5-60e9291820fe/e79ef2036cc7935542138f5da16a981b

My setup is:
Dlink DIR-855
Firmware Version :1.21EU,  2010/01/15
Modem: DSL-2680
(not sure how to access the modem or check the firmware)

If anyone can offer any advice as to what I may have missed that's preventing me accessing this remotely I'd be hugely grateful.

Many Thanks

My suspicion is that you'll need to forward the ports to the router from your modem.
That is to say, a request comes in on port 5000, the modem forwards it to your router, then your router forwards it to you Synology NAS.
The default web configuration IP for your modem is 192.168.1.1.  Otherwise, look in your router settings to see what the "Gateway" address is.  That should be the IP for your modem.

Link>Welcome!

Internet Service Provider and Modem Configurations
  • 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.
    Example of a D-Link router configured for PPPoE with ISP Modem bridged: PPPoE Configuration on Router
  • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
  • For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
