Is there any way to connect to Wireguard behind a Carrier-grade NAT? I have a backup LTE connection, without proper public ip + I have a home server with Wireguard.

SIDE_A = LTE connection, without public IP, NAT

SIDE_A_SERVER = WIREGUARD (connecting to sideb.dyndns.org)

SIDE_B = VDSL with public ip + ddns (sideb.dyndns.org)

SIDE_B_SERVER = WIREGUARD (cannot connect to SIDE_A, no public ip)

Best regards,

Adrian
