[tor-relays] port 9001 udp

[zwiebel at quantentunnel.de]

Hi relay-tives!
 
It's my first post here, so please can someone help me with my question
 
Why do I have to open 9001 UDP at the DSL router firewall and not necessarily in iptables?
Is it something specific on my side or does someone has an explanation?
 
The OR service seems to work. Ok - I see nearly no traffic may-be because of my small
bandwidth. See some information about my system
 
Setup
    PC (P4 2GB noHDD) with USB-LAN adapter (eth2) connected to DSL router (NAT & firewall)
    Tails 0.20.1 on SD card with USB adapter write protected
    Server IP x.x.x.33 received from the DHCP DSL router
 
Goal
    Run PC as OR relay non exit
    Run OR service
    Dont run DIR service
 
DSL router setting
    Open DSL router firewall IP x.x.x.33 TCP 9001 for OR
    Open DSL router firewall IP x.x.x.33 UDP 9001 for OR <= IS THE POINT
 
Done to tails manually each time the PC turns on (amnesia!):
    Root terminal (password) and "/sbin/iptables -A INPUT -i eth2 -p tcp --dport 9001 -j ACCEPT"
    The the only change to original tails iptables list is the added rule
 
Done to Vidalia: relay-non-exit, nickname, email, port=9001, bandwidth limits typ 20kByte/s and max 25kByte/s
 
The log messages tell me success and all runs for a week.
 
Thanks front-up
 
Zwiebel
