Hey all,
Like I said in the topic, ChangeIP rocks the cash bar.
However, when I am running all the nice firewall rules that we can pull off the demo router from Mirkotik, I get a timeout.
What port must I allow through so that my updates will work??
Cheers 
The only ports you should need to allow outbound are the following:
udp/53 (dns queries to look up hostname)
tcp/443 (ssl update page)
You do not need to open any ports inbound. If you are filtering on the output chain you might need some established / related rules to allow the replies to router generated traffic.
