I'm sure these questions have already been answered but I looked all over and wasn't able to find the answers. I would appreciate it if someone can help me

1) I've noticed Fedora 14 has a built in firewall application enabled by default, do I need to make any changes to it (it currently only has the SSH firewall rule checked)?
2) Does the Fedora 14 firewall settings affect Amahi's performance (remote access, apps, DNS, etc.)?
Thank you,
