Ok, I seem to have it working now using eskilbred’s answer on the page linked here. I’ve got NTRIP over cellular, UDP AOG functioning with GPS over UDP and cellular internet is working on the tablet at the same time.
Heres the original fix working on v1809
HKLM\Software\Microsoft\WcmSvc
IgnoreNonRoutableEthernet (REG_DWORD) set to 1The v1909 fix is another registry tweak. this one is located in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WcmSvc\Local
fMinimizeConnections (REG_DWORD) set to 0I setup a bunch of PD laptops that use a VPN service over cellular but also dock to a server in their car. This allows the non routable ethernet to still connect without taking priority of cellular.
Hope this helps!
