hAP ax lite LTE6 site to site vpn

Hi,

i want to buy hAP ax lite LTE6 and add sim card with 4/5g mobile network.
And want to create site to site vpn between this Mikrotik and other Mikrotik.
Is that posible with router with sim card ? There is any issues with that ?
The ISP provider will shutdown CGNAT for me.

Also is it posible to create a DDNS with that router and mobile network ?

Quite well possible.
Easiest solution would be wireguard, it’s the fastest option.

DDNS is possible using Mikrotik’s Cloud services but when using Wireguard, you only need 1 side to have a fixed IP.
