Routers that use [[network address translation]] (NAT) must maintain tables of source and destination IP addresses and ports. Because BitTorrent frequently contacts 20–30 servers per second, the NAT tables of some consumer-grade routers are rapidly filled. This is a known cause of some home routers ceasing to work correctly.<ref>{{cite web|title=FAQ:Modems/routers that are known to have problems with P2P apps |website=uTorrent.com|url=http://www.utorrent.com/faq.php#Modems_routers_that_are_known_to_have_problems_with_P2P |archive-url=https://web.archive.org/web/20080913085527/http://www.utorrent.com/faq.php#Modems_routers_that_are_known_to_have_problems_with_P2P |archive-date=13 September 2008|access-date=7 April 2013}}</ref><ref>{{cite conference |author=Halkes |first1=Gertjan |last2=Pouwelse |first2=Johan |year=2011 |title=UDP NAT and Firewall Puncturing in the Wild |url=https://books.google.com/books?id=j6HPyxvPFcsC&pg=PA7 |conference=10th International IFIP TC 6 Networking Conference, Valencia, Spain, May 9–13, 2011 |publisher=Springer |page=7 |isbn=9783642207976 |archive-url=https://web.archive.org/web/20130509032124/http://books.google.com/books?id=j6HPyxvPFcsC&pg=PA7#v=onepage&f=false |archive-date=9 May 2013 |access-date=7 April 2013 |work=Proceedings of the Networking 2011 Conference |editor=Jordi Domingo-Pascual |display-editors=etal |url-status=live |df=dmy-all}}</ref>
