Because we do not need any caching, but only the access restriction part, I choose tinyproxy because it is very light weight and simple.
The only downside is that the tinyproxy that sits in Ubuntu 12.04 does not listen on It support both IPv4 and IPv6 at the same time 
2013-01-04 Shame on me... I didn't test properly but the good news is that tinyproxy does work on both protocols 
I assumed that this result:
root@proxy:~# netstat -tlnpvw | grep tinyproxy
tcp6 0 0 :::8888 :::* LISTEN 3946/tinyproxy
meant that it didn't listen on v4... but I was wrong. In summary:
| Code Block | ||
|---|---|---|
| ||
Listen :: #This will accept connections on IPv6, but also on IPv4: IPv4-mapped IPv6 addresses are used: #CONNECT Jan 04 15:29:13 [23566]: Connect (file descriptor 6): host.terena.org [::ffff:192.87.30.2] Listen 0.0.0.0 # This will listen on IPv4 only Listen 2001:610:148:dead::666 # This will listen only on the specified IPv6 address. Not nice, but workable. |
