@Joepke Thanks for the update.

 

I just put mine into production over the weekend.  I wasn't able to backup the OC200 and restore everything to Linux Controller (even though both were running 5.9.3x), I had to Migrate the sites from the OC200 to the Libre board one by one.  For what it's worth, the PiHole consumes very little in the way of CPU resources when running, so not a great source of heat.  The only concern is at startup/power cycle...even with the heatsink, mine hits 55'C after firing up both containers...before idling back down to 40-42'C steady-state.  FYI at 60'C the Libre drops itself down to 100Mhz as a self-preservation mechanism.

 

@Joepke this is the tiny heat sink I am using. 

It is good enough so far...probably fine as long as I don't ever do continuous video playback.

I've expanded my pi-stack, now in addition to Pihole and Omada I have:

 

- added SNMP support to the base Armbian OS and connected it to my LibreNMS (unrelated)

- added a container for 'portainer' which provides a nifty GUI interface for the other containers running

- added 'wg-easy' container which gives me Wireguard (kills me how long I've been waiting for this on the ER605 and in about 20s, it's installed and running on this!)

 

 

 

This was a no-brainer...the Armbian 22 OS has native WG support pre-built!

 

 

and this was really for just monitoring the temp...but it does so much more!

 

 

Did some initial Wireguard performance tests on LePotato board.  I easily maxed out the 30M uplink at about 10% CPU load, so I am quite sure I can saturate the onboard 100M Fast Ethernet port.  Thinking ahead, I have now verified that a TPlink UE300v4 GigEthernet USB3.0 adapter (USD$10-15) works just fine in one of the 4 USB2.0 ports, and can be hot plugged without causing the 2.0A phone charger I'm using as a power source to blip.  When I get out to a site with a faster connection, I'll try this setup and see what kind of VPN performance I can achieve running Wireguard in a Docker container on this increasingly surprising little board.

 

I was able to get 76.6Mbps through using two > 100Mbps connections at either end and an older Android phone. 

CPU was maybe 20-30% tops, hard to tell with the multiple worker threads.

 

I'll know if that's the upper limit for sure when I am able to test with the USB GigE adapter and a proper laptop.

 

The system static state running the Wireguard, Portainer, Omada and PiHole containers is as follows:

 

System load: 4%           Up time:       3 days 4:45 Local users: 2            

Memory usage: 72% of 1.89G  Zram usage:    61% of 0.94G  IP:       172.18.0.1 172.17.0.1 192.__.__.__

CPU temp:      41°C           Usage of /:    14% of 29G    

RX today:      669.7 MiB

 

So pretty good, but creeping up there in RAM usage (still more than 25% left which IS actually more than 500MB...so, not too fussed).

Added DDNS support tonight.  Found a great little container with a sub-10MB RAM footprint.  Handles just about every known dynamic DNS provider out there.

 

 

With the latest beta code for my router I can now use the ER605 to do the DDNS thing (my public IPs are not guaranteed static), so I don't really need this container anymore. I just haven't gotten around to removing it yet :) but I will and will replace it with something that does Let's Encrypt...which would pretty much address all the major shortcomings I have with this router.
