How to get the Chromecast to play nice across VLANs with an Edge Router Lite
Background
My reason for compiling this information is simple, I couldn\’t find one source that let the Chromecast play nice across VLANs on my Edge Router.
Equipment
- Ubiquiti Edge Router Lite 3
- Ubiquiti UniFi AP AC Pro
- HP ProCurve 2810-48G
Problem
- Chromecast cannot be seen across isolated VLANs
Resources
- Crosstalk Solution’s video on simple Ubiquiti VLAN configuration. This provides a good overview of setting up VLANs and firewall rules on the ER-Lite.
- Crosstalk Solution’s video on secure IoT network configuration. This provides detailed info on creating firewall rules to make sure traffic stays isolated between VLANs.
- The Hook Up’s video on setting up IoT VLAN rules with UniFi equipment. This video provided an insite into configuring settings on the UAP-AC-PRO.
- xdeb.org’s article Setup guest and IOT VLAN with UniFi and a EdgeRouter. This is useful for enabling DNS forwarding for VLANs.
- Cron Blog’s article Edgerouter and Chromecast. This is where I knew I was getting close to the solution. Specifically, setting up the mdns repeater and broadcast relay.
- Multicast, Sonos, Phorus & Play-Fi Broadcast 255.255.255.255: Discovery Solution found on Ubiquiti\’s forums. This post contains the instructions for downloading and installing the broadcast relay service onto the ER-Lite.
Takeaways
It was a long road to get the Chromecast to be seen across VLANs, but it’s working now. I hope these resources can help someone else on this journey.
Sync iCloud Contacts and Calendars with Thunderbird
There are only two add-ons needed to sync iCloud contacts and Calendars with Thunderbird: Provider for CalDAV & CardDAV and TbSync. Together, both of these add-ons provide everything necessary to enable iCloud Contact and Calendar syncing for Thunderbird.
Setup of both these add-ons is straightforward. In Thunderbird, navigate to Tools -> Add-on Preferences -> TbSync. In the TbSync Account Manager, click Account Actions -> Add Account -> CalDAV & CardDAV. Select iCloud for the account type and follow the wizard to completion.
Once finished, enable the account, and select which calendars and contacts to sync. Be sure to set a synchronization time as well.
Another useful add-on is CardBook. CardBook’s iCloud sync is independent from TbSync. TbSync puts iCloud contacts in the Thunderbird address book, while CardBook uses its own address book which opens in its own tab.
Setting up TRIM under Manjaro Linux
Manjaro Linux is based on Arch Linux, and Arch includes a package "util-linux" which provides two services for TRIM, "fstrim.service" and "fstrim.timer".
From my brief research I found that it is reccomended by the Linux community to run "fstrim" no more than once per week. This is to prevent excessive wear and tear on the SSD.
To enable automatic Trimming, run the following commands in a terminal.
systemctl enable fstrim.timer
systemctl start fstrim.timerTo check the status of "fstrim.timer", run the following command.
systemctl status fstrim.timerThe status output should show:
Active: active (waiting)That’s it! TRIM is now enabled and will run once per week with the fstrim.timer service.

TextEdit and Blank Documents
From Mountain Lion and beyond, launching TextEdit results in being confronted with the Document Picker. Fortunately, the old behavior can be restored by running a simple defaults write command in Terminal.
defaults write -g NSShowAppCentricOpenPanelInsteadOfUntitledFile -bool false
The post-Lion behavior can be re-enabled by running a defaults delete command in Terminal.
defaults delete -g NSShowAppCentricOpenPanelInsteadOfUntitledFile
