TOR Port: $tortle_tport (Redirected to localhost:$tortle_lport)\n\n\

===========\n\
|
||||
At this time, it is just a regular TOR Proxy but my plan is to evolve it into a much more convenient and secure fully isolating Gateway.\n\n
|
||||
The LAN Turtle (with its two ethernet interfaces) is clearly perfect for that purpose, although I have to figure the best way to do it without
|
||||
affecting the functionality of other modules/services that may be running at the same time (some iptables playing needed too).\n\n\
|
||||
In the meantime, please notice that DNS or other well known leaks are NOT being actively prevented. Use it accordingly.\n\n\
|
||||
TOR Proxy is in $tortle_socksip:$tortle_socksport\n \n" 33 72
|
||||
TOR Proxy is at $tortle_socksip:$tortle_socksport\n\
|
||||
TOR Transport is at $tortle_socksip:$tortle_transport\n\
|
||||
TOR Dnsport is $tortle_dnsport\n\
