Sir i use vuze a lot for downloading. my problem is that it always shows *NAT reachability Problem, No Incoming Connections* (icon corresponding to NAT in the bottom right section of the screen is always red) With bit of 'googling' i found that if i can solve this problem, i can download faster with torrents.
there is a page http://www.azureuswiki.com/index.php/NAT_problem *solution given there is * The commands below can be entered in a root terminal session to open the ports (TCP and UDP) *iptables -I INPUT -p tcp --dport <your_port_number> -j ACCEPT **iptables -I INPUT -p udp --dport <your_port_number> -j ACCEPT* *<your_port_number>* is the port number you have used for port forwarding (Avoid 6881-6999, any from 49125-65535 is fine) Once you've established the port is open you need to make the change persist through a reboot *create a file* /etc/init.d/iptables_azureus *and add the lines below* (sleep 220 /sbin/iptables -I INPUT -p tcp --dport <your_port_number> -j ACCEPT /sbin/iptables -I INPUT -p udp --dport <your_port_number> -j ACCEPT ) & The *(sleep 220* is there to make the script wait a few minutes to allow subsequent firewall configuration scripts to run. 220 seconds is a large value and you may choose to configure a lower value. The key is that the opening of the azureus port is not countermanded by the firewall initialisation which runs later. At the end is a *) &* which allows the script to let the rest of the boot continue, while the script waits. chmod +x /etc/init.d/iptables_azureus *make the file executable* update-rc.d iptables_azureus start 51 S . *links the file into the startup sequence* So i created a file iptables_azureus in /etc/init.d as *#! /bin/sh (sleep 220 /sbin/iptables -I INPUT -p tcp --dport 63549 -j ACCEPT /sbin/iptables -I INPUT -p udp --dport 63549 -j ACCEPT ) & chmod +x /etc/init.d/iptables_azureus update-rc.d iptables_azureus start 51 S * then on *execution of iptables_azureus*, i got the following error: *debian:/etc/init.d# /etc/init.d/iptables_azureus update-rc.d: warning: /etc/init.d/iptables_azureus missing LSB information update-rc.d: see <http://wiki.debian.org/LSBInitScripts> Use of uninitialized value $level in string ne at /usr/sbin/update-rc.d line 199.
