Port Forwarding with Router Telnet Interface

MetaMan · 09-09-2012, 08:30 PM

I have a router that only allows you (for the most part) to configure it by logging in with telnet. I have been trying to expose my Minecraft server to the internet and have been having some issues.

After logging in with telnet, I get this:

Code:

   Main Menu

1.  ADSL Link State
2.  LAN
3.  WAN
4.  DNS Server
5.  Route Setup
6.  NAT
7.  Firewall
8.  Quality Of Service
9.  Management
10. Passwords
11. Diag
12. Reset to Default
13. Save and Reboot
14. Exit
 ->

The server's internal ip is 192.168.1.50. If I connect to this within Minecraft, I am able to play just fine. Using my router's weird telnet menu-y system, I created a 'virtual server' under the 'NAT' submenu with this options:

Code:

 Virtual Server Show

Server Name     Proto.  External Start  External End    Internal Start  Internal End    Server
                        Port            Port            Port            Port            IP Address
Minecraft       TCP&UDP 25565           25565           25565           25565           192.168.1.50

Any ideas on how I should proceed from here? I cannot currently connect with my external ip.

well the router brand would help but I guess that looks correct (other that it technically being TCP traffic only), however maybe you need to also explicitly open the firewall port as well as enabling the forwarding?

And you do mean minecraft server right? Not just opening the client to the LAN, as that picks a different port each time.

Yes, It's a full-blown server. Craftbukkit, to be exact. The server is starting on the right port. The router model is "BCM96358 ADSL Router"
Under the firewall submenu, there is only 'IP Filtering' and 'MAC Filtering'.

Any other ideas? Also... when I enter my router's external IP, it asks to log into my router. (It has an html interface but it doesn't allow configuration. It just shows status information. That's why I have to use telnet) Is there a reason it's doing this?

Ahh, ok so have you not tried this from a remote location? Maybe routers will apply these configs based on the ingress port of the router. So it's not until you enter from the Internet side of the router that you will see anything happen. Same (well.. opposite...) goes for the management page, it's not the IP you're going to that matters, it's that you're requesting port 80 (or 443 etc) from the router by going in through the internal side.

Thanks!

I'll see if I can get a friend on the outside to connect.

MetaMan · 09-11-2012, 07:17 PM

People outside my network still seem unable to connect to my server. Any other suggestions?

acid_kewpie · 09-12-2012, 02:09 AM

Well i'd still look at the firewall side of things, what is under IP filtering?

MetaMan · 09-12-2012, 03:52 PM

Code:

   IP Filtering Menu

1. Outgoing
2. Incoming
3. Exit
/ Firewall/IP Filtering ->

If you select "Outgoing" or "Incoming" you get a menu that looks like this:

Code:

   Incoming IP Filtering Menu

1. Add
2. Remove
3. Show
4. Exit
/ Firewall/IP Filtering/Incoming ->

Selecting "Show" gives you this:

Code:

        Incoming IP Filtering Show

Filter Name     VPI/VCI Proto.  Source          Source          Source  Destination     Destination     Destination
                                IP Address      Subnet Mask     Port    IP Address      Subnet Mask     Port

right, so fill that in. Not sure what else I'm supposed to tell you tbh.

What do you recommend filling in where? And isn't this for blocking IP's?

acid_kewpie · 09-14-2012, 12:58 AM

well everything would be denied by default.

so source I guess you'd set as 0.0.0.0/0 or something, destination is presumably the internal IP, but might be your public one. and the dest port is the minecraft port.
