Hi, When adding a IP to an IP>firewall>address list with a timeout (say 4d 00:00:00) and adding a comment in 6.39.3, it drops off within 24hours (and not when the timeout is reached). Doing the same in v6.38.7 it doesnt drop off and continues to count down till its timeout is reached. I have tested...

I have a problem with address lists under the IPv4 firewall since upgrading to 6.39.3. This is on both an RB2011 and a hAP AC. If I make an entry with a timeout it is deleted much sooner than it should be. Entries seem to last about 7 minutes for every 12 hours of timeout, or 14 minutes for 24 hours...

IP -> DHCP Server

This is configured per interface on a Routerboard. Make sure the "internal" router doesn't have its "external" interface listed.

My hAP AC idles at 59 degrees Celsius in a room that is around 21. Is this normal?

They do not have to be on the same switch chip, something else is wrong with your setup.

This is probably easier to accomplish from the web server itself if you have another ip to spare.

Can the RB2011 be configured via USB? If not, what is the point of a micro USB connector instead of a full sized A connector?

Try turning off the LCD to get a little more performance, those graphs do not come free.
