After 2 hours for googling, I finally for ClockworkMod tether to compile and run on Fedora 17 x64. Only catch is I have to disable firewall when I am running it, and I am not comfortable doing that. I would like to add a rule to firewall to allow this particular application through it. Is there a way I can do that? If not has anyone figured out the ports that I need to opened?

use tcpdump -i eth0 to identify the ports, where eth0 is the interface that is connected to the internet – Serge Oct 21 '12 at 21:21

I have just been through this process myself. I am using openvpn VPN client on the phone and VPNBook VPN provider and clockworkmod tether:

The rules I added to make things work are:

iptables -I INPUT 1 -p udp -s -j ACCEPT     # Tethered phone?
iptables -I INPUT 1 -p udp --sport 123 -j ACCEPT    # NTP.
iptables -I INPUT 1 -p tcp --dport 50001 -j ACCEPT  # Clockworkmod node process on Linux.

Can add the following to firestarter's /etc/firestarter/user-post file:

$IPT -I INPUT 1 -p udp -s -j ACCEPT
$IPT -I INPUT 1 -p udp --sport 123 -j ACCEPT
$IPT -I INPUT 1 -p tcp --dport 50001 -j ACCEPT

I need to do further investigation to see what is and to lock down to specific NTP servers.

Hope this helps.
