Remote access for home assistant - double nat issue with google mesh wifi

Hi

Wondering if anyone has run into the issue of having their home assistant on a google wifi network which is different to the primary network (Double NAT). Issue is I’m trying to access hassio remotely either by using vpn server on 1194 or SSL over 443, the former being the preferred option, though neither are working and I believe it’s because the ethernet network can’t see the wifi network.

If I could I would just bridge the primary router but I can’t because I’ll lose by VOIP phone

Any ideas would be appreciated
