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.
