Dlink Ticket System - DDNS DIR-895L
« on: June 06, 2017, 04:12:02 PM »

Hi!!

Sorry. Its my first post...
But I was wondering if someone have already used Dlink TICKET system ?
Because I submitted a ticket about an issue in DIR-895L DDNS  in 22 May, but no answer received until now 6 June.
The Ticket staff takes so long to respond ??

Following my issue in DLINK TICKET:

Hello,

The DDNS feature stops working when the router is not able to resolve the name 'DynDNS.org'.

Following is the router log:

"

[Time]Sun May 21 02:17:30 2017
[Message:109]Update 'XXXXXXXXXXXX' to 'DynDNS.org' successfully, the IP address ((NULL)) is not changed.
--------------------------------------------------------------------------------------------
[Time]Sun May 21 03:18:00 2017
[Message:110]Unable to resolve the IP address of 'DynDNS.org'
--------------------------------------------------------------------------------------------

"

Operating system :Windows 7 (64 bit)
Hardware version :A1
Firmware version :1.12

No idea about the ticket system, never needed official support, but I might be able to help with the problem. Are you using static DNS or DHCP? Do you have DNS relay enabled?

Hello,
Sorry for the delayed answer.

I dont have DNS relay enabled.
I m using static IP in my broadband connection (I have a DSL modem from DLINK as well...).

My broadband IP is supplied by my internet provider

My DDNS (DYNDNS) works properly. But when my router tries to resolve the name DYNDNS.ORG and the connection is not available....the problem starts...The status in DDNS configuration page is "disconnected"...and unless I reboot router or disable and enable ddns settings the router DIR-895L doesnt start the DDNS service again.

Its annoying!! Im very disappointed !!! Its a basic BUG in the system and DLINK do nothing about it!!!

Thank you for trying to help me!

If static IP I assume static DNS. Are you using your ISP's DNS or something else? When it happens when you go Windows key + R > CMD > nslookup DynDNS.org when the problem happens? Can you PC resolve the domain when your router can't?

Link>Welcome!


  • What region are you located?


Internet Service Provider and Modem Configurations
  • What ISP Modem Mfr. and model # do you have?
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

The problem is that my connection really drops sometimes. And if in this moment the router DIR-895L tries to resolve name DYNDNS.ORG the DDNS (DIR-895L) does not try to update the name anymore...

What do you  mean "the connection drops"? Can you answer the rest of Furry's questions? What kind of modem do you have? What kind of ISP or who is the ISP?

If the connection to the router goes down, it won't be able to update DDNS. That is normal. If you want to fix it, why does the connection keep going down?

I know if the connection to the router goes down, it won't be able to update DDNS.

I wont be able to resolve my connection problems. Thats not the point.

When the connection of the router goes down and the router tries to resolve name
DYDDNS.ORG the DDNS feature of the DIR-895L stops working.

THE PROBLEM is when the connection goes up (back to normal) the router DIR-895L doesnt try update DDNS anymore
(unless I reboot the router)

P.S. My modem is a DLink DSL-2500E

Do you have internet if you don't use DDNS or if you have DDNS enable, do you have internet access else where or is our entire access not working?
Do you have PPPoE on the modem or at the 895 router?
If at the router, be sure Always Connected is enabled.

I use DDNS at router DIR-895L because I dont have a static IP (WAN side).
And I use DDNS because I have an FTP server and surveillance IP cameras.

I have PPPOE on the modem DSL-2500E (always connected).
At the router DIR-895L I have Static IP connected to the modem.

The set DIR-895L and DSL-2500E works good. But here in Brazil our internet service provider has many problems and the connection goes down frequently.

When the modem connection goes down, and during this period the router DIR-895L tries to updade DDNS (I set each hour to update), it stops to update. The modem connection goes up and DIR-895L doesnt update DDNS (never more unless I reboot the router)

Thank you for the support!

I'll pass this on to D-Link for review. I would start a phone contact with your regional office about this as well.

You need to make sure the DSL modem is in full bridge mode. We believe your modem is acting as a router as well and causing a double NAT condition which would cause problems like this. Make sure the Modem is bridged and let the DIR series router handle the PPPoE connection. Check the user manual for information on how to bridge the modem or ask the ISP for additional help and information regarding bridging the modem. You'll need your PPPoE account user name and PW to enter in to the DIR router so it can authenticate correctly thru the modem to the ISP service.

Yeah, I can test the router handling the PPPOE connection to see if the problem occurs.

But there is a  reason to let my modem handling the PPPOE connection and router with Static IP.
By this way Im able to access the modem web server! If I let the DIR-895L with PPPOE connection I can't access the modem (unless I change the cables... :))

I set the DMZ IP in modem settings to my DIR-895L router. So my Port Forwarding Configs remains in DIR-895L!

I dont believe that is a double NAT condition. This problem only happens during the connection down.

I still believe that is a basic BUG in DIR-895L (easily reproduced by the way)!!

Thanks!!!

The problem is the double NAT condition.

Hopefully using DMZ on the most will help.
