I do simply run here
~/devel/go/src/snowflake/proxy/proxy &>>/tmp/snowflake-proxy.log &
and was wondering if I have to open special UDP inbound ports ?
[...]
but b/c I do have a rather restrict inbound firewall rule set I'm wondering about that.
If you have a restricted firewall you might have what snowflake calls 'restricted NAT', the most useful snowflake proxies are the 'unrestricted NAT' ones, as they allow clients in a more restricted NAT situations to connect to them. You can check the NAT type you have in the logs.
If you have restricted NAT I would recommend you to open the UDP port range of 32768-60999.

There as a conversation about that in the forum few months ago: https://forum.torproject.net/t/a-few-questions-about-the-standalone-snowflak...
