Cannot connect to work VPN
I have a huawei fiber modem which is connected to deco x60 via cable. I disable huawei's wifi and only use deco's wifi signal at home. Problem is that my work vpn doesn't connect when using deco. For testing purpose, I enable huawei modem's wifi and vpn works without an issue. I couldn't see any setting called "vpn passthrough" in the app.
I both tried AP mode and Router mode and it is same.What could be the problem?
