Thanks for your comments. I will a look at Dante.

1. Any updates about Dante?

2. By the way redsocks does also support UDP, and redsocks is imho much more easy to configure.

3. I successfully managed to connect to http://check.torproject.org (and other http sites) using transparent proxying. Showed a jondo IP.

Brief setup:
- redsocks and jondoconsole were running under a linux user account redsocks, which was privileges to establish direct connections.
- iptables redirected all other users traffic to redsocks IP 127.0.0.1 port 12345
- redsocks redirected the traffic to IP 127.0.0.1 port 4001 proxy type http-relay
- proxy type http-connect did not work at all

Like said above, I could only access http sites. I couldn't access https sites. Redsocks output: "accepted, malformed request came, httpr_toss_http_firstline, dropping client".

Are you interested at all in allowing jondo free cascade to transparently proxy? It's a business decision.

If you are interested I can sketch down the setup more comprehensive (step by step instructions, complete configuration files, etc.)... And perhaps we were able to get https working as well.

No - sorry. I did not found the time for this.

I will try redsocks tomorrow and have a look. May be, it is a better solution than transocks_ev.
