Title: Can't open ports in the router
Post by: lychnood on July 24, 2017, 10:54:45 AM

Hi, good afternoon!

So, my problem is that I'm trying to connect to an FTP server and can't seem to do it no matter how hard I try. I figure it must be a port problem and I've been follwing tutorials to try and solve the problem for the past 4 hours and can't get anywhere.

Port Forwarding and Virtual Server do nothing to open ports since none of the values I input actually seem to work.

Router: Dlink DIR-615
H/W Ver.: T1
Firmware Version: 20.06.

I'm in Brazil using a DSL service.

Internet Service Provider and Modem Configurations

What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
If the ISP 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 (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://computer.howstuffworks.com/nat.htm). Call the ISP and ask to see if the ISP modem can be bridged. 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 (http://www.dslreports.com/shownews/Networking-101-The-DMZ-137550). Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.

Turn on or off DNS Relay (http://forums.dlink.com/index.php?topic=45143.0) 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.
Setup DHCP (http://forums.dlink.com/index.php?topic=58017.0) 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 (http://en.wikipedia.org/wiki/SPI) to test.
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 (http://forums.dlink.com/index.php?topic=4235.0) 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.
