I have an update!
I can't confirm any of this for certain but I believe I have had two simultaneous issues with one masking the other.
First, thank you SO much for sharing that TSB, OPNenthu! It was almost certainly a contributing factor.
So, since my last post I added the Tunable temporary correction for the TSB issue and while my connection was "stronger" and the VPN didn't fall over as quickly as it had, it did eventually crash out a few more times. I then decided to move my network back to "Setup 2" (with the Raspbery Pi connecting it's own VPN and behind the managed switch) but this time I connected the LAN and WAN both to the SFP's as opposed to the ETH ports. (I then had no traffic flowing through the OPNsense/VP2440 ETH ports.)
Now, I had to really push to saturate the line before the WAN would ultimately start building up with Ping Loss but if I dialed it back somewhat, it would stay connected and start getting back to a normal connection latency!
TL;DR: The VP2440 TSB was definitely an issue but I think I may have also been over saturating my bandwidth and with both issues in tandem, the VPN was never able to repair itself like it can using the SFPs.
So for now, the setup stays as is until there is a fix for the TSB and I can try again. Again, short of the TSB, this never happened with my pfSense but I also can't say for sure that I had the bandwidth pegged as much as I have been with the OPNsense.
Thanks again OPNenthu! I'm really not sure I'd have found that TSB without you so I'm glad I posted here.
Will update again it anything changes in case anyones following along.
