Hello,
I have an ASUS RT-AC3100 router on ASUSwrt Merlin, and something seems to be preventing my iPhone from using Wi-Fi Calling.
When on any other network, it works fine, but on my network, the "Wi-Fi Calling" carrier signal shows up only for a second, as if the VPN tunnel is terminated.
I know for sure my network is the problem because I have a personal and a work iPhone on different carriers and the exact same issue is happening.
My ISP is Bell Fibre (Toronto), and it is connecting using PPPoE.
Things I have tried:
- Disabling Firewall on router (so all ports including 500 and 4500 are open)
- Enabling VPN passthrough on router (including IPSec)
- Changing DNS on router
- Enabling IGMP snooping
