My PSP isn't working with Xlink Kai. Some people said it was because I probably had a firewall up. I went into network and it said the firewall was off but people told me that there was somewhere else to check if I have a firewall up. They said "router settings" is where you have to go to check. Cuz I have a router.

My question is, how do I check if I have a firewall up?

Look in your router's manual. It should tell you how to configure the firewall.

Yeah, routers constitute an automatic firewall (most if not all), and you have to punch holes through them to unblock specific ports. You can check your firewall with Shields Up.
