Adding new rules

Guess guarddog is running. What if i manually add a rule to iptables?
When I run guarddog and apply something it will erase the rule I done?
If I reboot, I will have to add  this rule manually again? Or guarddog
knows it and loaded when i ran it? In case guarddog saved the rule and
I don't want the rule anymore, how should I proceed?

Also, I allowed bitorrent internet/local local/internet and it doesn't
work, anyone having the same problem?
