Ultrapeers help others connect to the network & handles a lot more traffic. There's no switch which allows you to become one. If the network is in need of one then it will find users to become one. But, to be a U.P. you definitely must be properly configured so there are no firewalls blocking in & outgoing traffic. If you have free bandwidth & slots for up & down traffic & have a fast connection then your chances of becoming a UP are greatly enhanced. Advantages of UP are more connections, disadvantages are greater traffic that doesn't apply to you.
