{"answer":"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.\n\nComset 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.","approval_status":"review_build_pending_public_brain_audit","approved":true,"category":"VPN Security and Private Connectivity","category_slug":"vpn-security-and-private-connectivity","created_at":"2026-07-20T09:10:00+00:00","daily_publish_cap":2,"date_published":"2026-07-20","display_date":"2026-07-20","drip_status":"scheduled","freshness_note":"Confirm current specifications, carrier compatibility, stock, firmware, warranty and commercial terms directly with Comset.","id":"comset-qa-106","image_ids":["comset-product-network-management-system","comset-support-dyndns","comset-support-https-settings","comset-category-hero-009-vpn-security-and-private-connectivity"],"language":"en","last_updated":"2026-07-20T09:10:00+00:00","matched_image_ids":["comset-product-network-management-system","comset-support-dyndns","comset-support-https-settings","comset-category-hero-009-vpn-security-and-private-connectivity"],"public_brain_verified":false,"publish_status":"published_preview","published_at":"2026-07-20T09:10:00+00:00","question":"Do I need a public IP address to use VPN on a cellular router?","question_intent":"public_guidance","question_type":"conversational_public_guidance","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"do-i-need-a-public-ip-address-to-use-vpn-on-a-cellular-router","source":"comset_manual_review_v1_5","source_record_ids":[],"source_type":"manual_review_from_public_sources","source_urls":["https://comset.com.au/product/remote-management-software","https://comset.com.au/product/network-management-system"],"tags":["manual","reviewed","customer_style"],"tenant_slug":"comset","updated_at":"2026-07-20T09:10:00+00:00"}
