				How the DIR-850L router should be set for Bonjour works ? Since I added this router to my network, Bonjour stopped working entirely: it can't resolve link-local names anymore. Multicast IPV4 and IPV6 are enabled; Unicast as well. What else can I do to troubleshoot this?

- What Hardware version is your router? Look at sticker under the router case.
 - Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the routers web page under status.
 - What region are you located?
 
Some D-Link routers don't have loopback support. 
Is IPv6 Firewall enabled? Might test to see if disabling firewall may help...
