Editing Port triggering (section)

{{Short description|NAT traversal mechanism}}
'''Port triggering''' is a configuration option on a [[Network address translation|NAT]]-enabled  [[router (computing)|router]] that controls communication between internal and external host machines in an IP network. It is similar to [[port forwarding]] in that it enables incoming traffic to be forwarded to a specific internal host machine, although the forwarded port is not open permanently and the target internal host machine is chosen dynamically.<ref>{{cite web|url=https://www.webopedia.com/TERM/P/port_triggering.html|title=Port Triggering|website=www.webopedia.com}}</ref><ref name="cisco-kb">{{cite web|url=https://sbkb.cisco.com/CiscoSB/GetArticle.aspx?docid=43a6b23d2caa4e7fae1b08a2a83253bf_Port_Triggering.xml&pid=2&converted=0|title=Port Triggering on Routers|website=sbkb.cisco.com|access-date=2017-12-31|archive-url=https://web.archive.org/web/20180628154519/https://sbkb.cisco.com/CiscoSB/GetArticle.aspx?docid=43a6b23d2caa4e7fae1b08a2a83253bf_Port_Triggering.xml&pid=2&converted=0|archive-date=2018-06-28|url-status=dead}}</ref><ref>{{cite web|url=https://www.linksys.com/us/support-article?articleNum=132863|title=Difference between Port Forwarding and Port Triggering|website=www.linksys.com}}</ref>
