TCP hole punching for Bitcoin nodes behind home NATs?

Test V4 V6
Office internet on Mac EIM EIM
Docker desktop on Mac using bridged networking on office internet APDM Failed to connect
Linux Laptop on office internet EIM Failed to connect
Docker using bridged networking on Linux laptop on office internet EIM Failed to connect
T-Mobile US hotspot EIM EIM
Home router (OPNSense) APDM No IPV6 is configured

*Update, there is no IPV6 at the office or on T mobile hotspot so the V6 results are wrong. I think Mac is being helpful and connecting over IPV4 as a fallback.
