IPv6+IPv4 dual stack LTE interface not working

Mon Nov 28, 2022 11:29 pm

Hi, in Ukraine celluar provider Kyivstar start give ipv6 for all clients, but after that all SXT LTE devices stop working.
To get them work again need go to the APN settings and change IP Type from Auto to IPv4, or IPv6.
If Auto set - lte interface doesnt receive any IP from celluar provider.

If is set IPv4 - everything is ok, interface receive ipv4 ip address, and everything works fine. Also if set IPv6, interface receive ipv6 address only and i have access to the sites and recources hosted at ipv6 addreses.
Tested this on a android devices, there in apn settings i can chose ipv4&ipv6, and its working, android device gets ipv4 and ipv6 addresses. But why this not working in mikrotik? Why no option ipv4+ipv6 in apn settings? Or this feature not supported yet?

Tested with SXT LTE, SXT LTE6, HapAC3 LTe6. Ros is 7.6 and latest modem firmware.
