Router Configuration Guide (TM DIR-615 G1)

I've created this section just to throw in some additional configuration options for the DIR-615. These options will allow you to address certain bugs that you may come across while using the TM DIR-615.

 

DIR-615 Port Forwarding

Port forwarding is required to allow other users on the Internet to access services that are hosted on computers within your private home network. This is done through the usage of the 'port forwarding' feature on the router. In order to setup port forwarding on your router :

1) Identify the port number (TCP or UDP) that you wish to forward. In this example, I will be forwarding both TCP and UDP ports 14355 to one of the computers on my private subnet (192.168.0.0/24).

2) Identify the private IP address of the system you wish to forward the port to. This guide will setup forwarding for a computer on my LAN network with the IP address of 192.168.0.50. I also recommend that you set a static IP address (as opposed to dynamic/DHCP) for this computer as the DHCP server may assign a different IP to that PC in the future and 'break' your port forwarding.

3) Check that your Windows or any other firewall application has whitelisted the application or port you intend to forward.

4) Navigate to your routers Port Forwarding page and enter the appropriate values :

5) The Name can be set to any value. The Public Port and Private Port fields should contain the value of the port that you wish to forward. Private IP should contain the IP address of the computer which is hosting the service. Most importantly, Public IP should be left blank.

6) Click on the "Save Settings" button and your router should now be forwarding the port. To check if it is working, run the application which utilizes the TCP/UDP port you have forwarded and visit an online port checking website such as http://www.canyouseeme.org/ .

7) The external port checker will inform you if the port is reachable by other WAN users.

Note : Some users have complained that forwarding TCP port 80 for HTTP hosting does not work because when they visit their WAN IP from the internal LAN, it shows the management GUI for the router instead of their web server. This is not true and the port is being forwarded properly (if the external port checker shows "success"). The reason you can't see the website you're hosting from your private LAN is due to NAT loopback. Other users on the WAN will infact be able to access your port forwarded HTTP server properly.

 

DIR-615 iPod/iTouch/iPad/Wifi Bug

There's basically been an issue with the default configuration of the TM DIR-615 G1 wifi router which causes certain wireless devices (mainly Apple ones) to be able to connect to the wifi hotspot but denied the ability to browse/surf the Internet. While I was testing out DD-WRT wireless configuration options, I noticed that when I changed the wireless channel width to 40 MHz, my iPod touch would be unable to connect to the wireless network or connect and be unable to browse anything. Other users have experienced the same thing on the stock firmware so here's a possible fix for that :

By default, this channel width/bandwidth option will be on 20/40 MHz (Auto) however if you're experiencing this wifi bug, try switching it to 20 MHz. This should fix the problem (hopefully!).
