Configure Huawei hg655b router for bonjour

This may be of use at least to Romanian AppleTV owners that have Romtelecom their Internet provider. After some struggle I've been able to properly configure Huawei hg655b router so that my AppleTV 3 is seen by iPad and macbook, both wired and wireless.

Here are the settings I tinkered with (after logging in into admin

- Basic -> Lan -> uncheck permanent lease

- Basic -> WLAN -> Select the SSID we use and: check WMM, uncheck AP isolation

- Advanced -> Firewall -> Select low (though I believe medium works fine, too)

- Advanced-> IGMP Snooping -> disable IGMP snooping

- (I'm not sure this is needed) Advanced -> UPnP -> enable UPnP

This way I've been able to finally see the airplay icon (and use it) in iTunes, mountain lion mirroring and iPad tray.

HTH.
