Question NETGEAR WGR614v7 & Static IP on Ubuntu 9.04 will not open a closed port with p. forw


Good evening friends,

After many hours of searching online, and pulling my hair out I have finally sunk to send out an S.O.S. to any that would be willing to assist me with my somewhat newbie knowledge of how to correctly configure port forwarding. My initial real problem (that I have been trying to fix by trying all the online tutorials or how to's that I've been finding online) is my torrent client will and would not upload. (I know torrents are a soft subject for the community, but please see past whether this is good or not) I can download with remarkable speeds just fine. I am able to browse the internet with ease.

I have used shields up's service and have found that every single port that I enter or common ports are stealthed.

I have read various places about the /etc/network/interface.

Mine looks like this:

auto lo
iface lo inet loopback

Ubuntu 9.04
Wireless router NETGEAR WGR614v7 (there are two computers: one is plugged into the wireless router and the other that I use is on a wireless card)
Configured static wireless IP with Network Manager (gnome) to 192.168.1.201 .
netmask 255.255.255.0
gateway & DNS Server 192.168.1.1 (Router address?)

The ports that I try to open seem like they are going through (I could be wrong) when I try netstat -ptnlu:

PID/Program name
tcp 0 0 0.0.0.0:9091 0.0.0.0:* LISTEN 22315/transmission
tcp 0 0 0.0.0.0:49191 0.0.0.0:* LISTEN 8121/python

tcp6 0 0 ::1:631 :::* LISTEN -
udp 0 0 0.0.0.0:49191 0.0.0.0:* 8121/python
udp 0 0 0.0.0.0:49982 0.0.0.0:* -
udp 0 0 192.168.1.201:57155 0.0.0.0:* 8121/python
udp 0 0 0.0.0.0:5353 0.0.0.0:* -
udp 0 0 0.0.0.0:1900 0.0.0.0:* 8121/python
udp6 0 0 :::49191 :::* 8121/python


I hope I haven't given too much information away, yet at this point I really am lost as to what to do. Any help at all would be most appreciated.

Thank you so much in advance.

Hi,


Port forwarding is usually done from the router. Indeed you need to make sure the port is open by your firewall in the linux box, but the rest is done at the router side.

This link shows how to do so for your router.

kind regard

Linuxlainen, thank you for your response.

I did try this before. After I fallowed the tutorial I get this error:

Server IP address must be a LAN address.

I typed my ending 192.168.1. 201


The tutorial asked me to type into my router 192.168.0.201

Why would it ask me to change the third quarter of the ip to a zero?

Thanks guys. Should I go to the netgear forums?

Also, should I EDIT my linux firewall then? And if so, how? Thanks.

Hi,

I'm not an expert in IP address format. However, commonly LAN IPs are set as 192.168.0.X. This could be the reason behind the issue you are facing.

I configured my system today for port forwarding, and I had to do nothing on Ubuntu box. All the settings were done on the router. I just checked through Network Tools in Ubuntu if my port is open, and that was it.

Double check you IP address.

Regards
Linuxlainen
