Not always. Many mobile services use private addressing or carrier-grade NAT, which means the old habit of expecting inbound access on a public IP no longer tells the whole story. Some deployments use VPNs initiated from the remote router outwards, while others use managed remote-access methods that work around the lack of a public address.
Comset generally looks at the end goal first: do you need a permanent site-to-site tunnel, occasional technician access, or central fleet management? Once that is clear, the access method becomes much easier to choose.
