contrary to what asdfgh1224 said, these ultrapeer connections allow you to connect to the network and be firewalled at the same time. if you did not have these connections, you would not beable to connect to the network at all. these ultrapeers are your "gateway" servers to connect to the network. the connections tab was probably accidently enabled. if you would like to hide that tab, goto view > show/hide and uncheck connections. unchecking this will not disconnect you from the network, it just hides the tab so you dont see it anymore. if you like it, then keep it, it really doesnt matter. but whenever you remove a host from your connections tab, LW will automatically try to reconnect to more of them.
