I need to share the company's internal network with a remote device.

The device needs to communicate with a server to transfer data. The only internet connection at this location is the operator's 4G. But they mask the public IP, so I can't close a site-to-site tunnel.

Please do you know of another vpn solution for this case?

    In order to establish the Ipsec VPN tunnel through 4G modem, You would have to open the following ports from 4G modem to Sonicwall Wan interface; ( Once you open below ports, follow the above KB shared by Mitatonge)

    1) IKE (UDP 500): This is the port used for the initial negotiation of the IPsec connection.

    2) ESP (IP 50): This is the port used for the Encapsulating Security Payload, which provides the encryption and integrity for the data being sent over the VPN connection.

    3) NAT-T (UDP 4500): This is the port used for NAT Traversal, which allows IPsec VPNs to work across networks that use Network Address Translation.
