Incoming VPN connection on Dlink dir-655
« on: September 28, 2016, 12:40:53 AM »

Dear members/guests,

Yesterday I've tried to set up a PPTP-VPN connection on the following configuration:

Cable Modem (Bridged Mode).
D-Link WAN: Static IP.
In Virtual Server:
Protocol Other 4 to let GRE pass through and
Port 1723 TCP to Local IP of a Synology NAS.

In the log of the D-Link attempts of the incoming connection were visible, but they were blocked.

For troubleshooting reasons I temporarily placed the local IP in the DMZ zone, but it didn't solve my problem.

Does anybody know if i've missed something !?!??

Greetings,

Jaap Wiggers
Amsterdam, the Netherlands

Link>Welcome!

  • What Hardware version is your router? Look at sticker under the router case.
  • Link>What Firmware version is currently loaded? Found on the routers web page under status.

Internet Service Provider and Modem Configurations
  • What ISP Modem Mfr. and model # do you have?

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.
  • Turn on or off DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.
  • 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.
  • Ensure devices are set to auto obtain an IP address.
  • Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI to test.
  • Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules.
