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   _||_  /    \ / O  O \ \ ____ /  \__//
