Title: Port Forwarding Not Working
Post by: wilsonhew on May 10, 2014, 07:23:08 AM
Dear all,

I am having issue with port forwarding on 850L. Current firmware is 1.10SG.

Tried both port forwarding and virtual server, nothing works. A simple SSH 22 port forward also does not work.

Any hint what should I try next? Tried another old router and it works better than this 850L.  >:(

Thanks,
Wilson

Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.

MTU is 1492
  • For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
Yes, always on

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.
  • Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
No such option
  • Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
  • Turn on or OFF DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0) and input new DNS addresses under Setup/Internet/Manual.
Yes, turned off.
  • Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Yes, running on DHCP
  • Ensure devices are set to auto obtain an IP address.
Yes, obtain IP address from router
  • If IPv6 (http://en.wikipedia.org/wiki/Ipv6) is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
IPv6 disabled
  • Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI (http://en.wikipedia.org/wiki/SPI) to test.
Tried both, still does not work.
  • Enable uPnP (http://en.wikipedia.org/wiki/Upnp) and Multi-cast Streaming (http://en.wikipedia.org/wiki/Multicast) under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
Tried turning on/off, still does not work.
  • Turn off WISH, and WPS under Advanced.
Turned off.
  • WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
Set to auto.
  • Set current Time Zone, Date and Time. Use an NTP Server (http://forums.dlink.com/index.php?topic=48695.0) feature. Tools/Time.

Thanks for your reply. Checked and don't think modem is the culprit. As I am using the same IP addressing for my old router (DIR-615) and port forwarding works.

I am out of idea...

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.

Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI to test.

Disable uPnP for testing Port Forwarding rules.

Thanks for your reply.

- Yes, checked. It is bridge mode. I am seeing my public IP address from the ISP instead of private IP address.

- Under Advanced/Firewall, no "Endpoint Independent for TCP and UDP" option. Yes, tried enable and disable SPI.

Is the uPnP disabled when you have PF rules enabled?

Can you give Virtual Server a try as a test with your configuration and see if that resolves this? Disable PF rules when you go to use VS.

1. Yes uPNP disabled under Advanced - > Advanced Network, when I tested with PF rules enabled.
2. Tried Virtual Server with PF disabled, uPNP disabled and SPI disabled.

It works when I put my server in DMZ, which I am trying to avoid.

Can you test with VS and uPnP enabled?

If DMZ is working, this could be a configuration issue...
What ports values are you using?
Is this to a PC or some device?
Title: Re: Port Forwarding Not Working
Post by: wilsonhew on May 14, 2014, 10:30:05 AM
Yup, tested VS with uPNP enabled.

I am trying with port 80, 443, 8443, 22, 5001, 1701, 500 and 4500.

It is a NAS. To eliminate issue with the NAS, I tested PF to a web server with port 80, 443 and 8443.

This is what I am trying to figure out, it works with my DIR-615 but not the 850L.  ???

Are you trying to gain access to the NAS or web server from a remote location?
I know have use D-Link DNS NAS and to access FTP, i'm only using port 21.
Thats one test you could try, set up port 21 for FTP and see if remote FTP works, if it also fail, I presume there is a configuration issue somewhere or something in FW.

If this fails, I recommend that you phone contact your regional D-Link support office, ask for level 2 or higher support.

Please let us know what they say.
