Websites these days set ridiculous TTLs like 1 minute. It's possible to force minimum TTL time to override what the site dictates. More reading: https://blog.apnic.net/2019/11/12/stop-using-ridiculously-low-dns-ttls/

How much RAM does the VM have? Did you try increasing it?

would anyone know if there is a way to prevent...

How To Create SSH Keys With PuTTY to Connect to a VPS | DigitalOcean. This will prevent it.

Tabs could be in rows instead of overflowing to the side. The main thing is m0n0wall's flavor of centralized collection of pages. Especially the status and diagnostics section.

My apologies for my initial approach to the matter.
Speaking of the m0n0wall type menu, I hope to see submenus go just one level deep like before. Sub- submenus could be tabs on top?

The tree like menus are horrible in my opinion. What was achieved by splitting the log pages into fifteen different places? There's not a huge work to be done; just put it back to where it was before. Technical specs for new menu theme - like m0n0wall.

Maybe my frustration in navigating came across as attitude. I have provided adequate details for you to understand what I'm talking about. Probably used a few question marks - to underline my frustration.

The "fastest way" is relative because it's still cumbersome and slow, compared to before it was rejigged. I'd like to propose a feature request for a legacy menu theme.

The menus are decentralized and cascading replaced by drill down menu, compared to before the fork. I understand there has to be some differentiation, but this seems like a step forward and then two steps back. Has anybody had to quickly check log files for this and that, ever? I tried doing it.

Okay great. As soon as I type 1508 into the MTU, the "calculated ppp mtu :" changes to 1500. After WAN reconnect, it's working.

Updated, did setup wizard after factory reset, twice. The Interface>WAN shows "calculated ppp mtu : 1492"

Couldn't get it to work. I did a reboot and checked ifconfig after setting MTU 1500 in (1)Interfaces>Wan, and (2)Interfaces>PTP>pppoe-advanced. I didn't try setting 1&2 together. I didn't see anything in the GUI; I'm on the latest dev.

I noticed that the MTU info field in Interfaces>Overview>Wan/lan is missing.

apinger looks for (1) bad quality connection, and (2) link down. The No.1 caused such issues^ for me. This setting gives me stable connection, instead of several or more reconnections a day.

Latency threshold: 700-999
Packetl loss threshold: 80-95
Probe interval: 10
Down: 50
Avg Delay Qty: 20
Avg packet loss qty: use calculated value
Loss probe value: use calculated value

Mostly found in FTTx(fibre) and in some cases (v)DSL. It's an extension to PPPoE that makes up for the PPPoE overhead & thus to have MTU like LAN - therefore less segmentation. This is assuming that the WAN port is gigabit capable because the MTU is set to 1508. It's prevalent in UK and rest of the world.

RFC 4638 - Accommodating a Maximum Transit Unit/Maximum Receive Unit (MTU/MRU) Greater Than 1492 in the Point-to-Point Protocol over Ethernet (PPPoE)

OpenBSD RFC 4638 support for pppoe

I'm not sure whether this classifies as a wish for FreeBSD or OPNsense, but here it is - baby-jumbo frames in PPPoE.
