Ports for League of Legends starting

Hello!

I am running LoL off a linux box. I have UFW (uncomplicated firewall) that denies by default and whitelists certain ports. I have all of the specified LoL ports open (triple checked). However, I can't start the client with just this. In order to start the client, I have to disable the firewall, start the client, and then once the initial dialog is up, I can enable the firewall again. I'm not sure if you use a port for some internet check that isn't listed on your FAQs, but I can't figure it out. It would be nice if I didn't have to have the momentary lapse of security though while I start up the client since the PC is public-facing.

Not a huge bug, but one I thought you all should know might exist.

Thanks, B.
