Can't open ports in my D-Link DIR-825

[Junker4598]

Hi,

It seems I can't open ports in my router (D-Link DIR-825). I have tried many different port numbers on both Port Forwarding and Virtual Server but the ports I open are closed according to http://www.yougetsignal.com/tools/open-ports/

For example I have opened port 8888 (both UDP and TCP, addressed to my local IP 192.168.0.107). This is my Apache port (configured with MAMP Pro) and I can access that port typing localhost:8888 in Google Chrome but not typing myexternalip:8888 when connected to another network (my iPhone's mobile network for example).

I have no software firewall or antivirus program installed (MacBook Pro, 2010, Yosemite) and I'm not behind a Carrier Grade NAT.

It sounds like you need to setup NAT to forward any incoming traffic on those ports to the local IP address of your macbook. Just opening the port won't do anything if your router doesn't have any services running on that port.

Rereading your post-you could have a number of issues. Are you able to access your webserver from another machine on the same network? That shouldn't require any sort of NAT/port forwarding. If not, you may have a firewall or perhaps apache is set to only listen on localhost.

Yes, I'm able to access the localhost webserver from another machine in the same network. (by typing 192.168.0.107:8888 in the browser)

I got it working now by changing UDP- and TCP Endpoint Filtering to "Endpoint Independent" in the router config. I can now reach the ports I've opened in Port Forwarding and I can access my Apache server with "my.external.ip:8888" from other networks.

How is this solution regarding security risks?
