VPN and Remote Workers on Business Broadband

Remote access concentrates load on your office upload: every file sync, RDP pixel and VoIP backhaul that hairpins through HQ competes with site-to-site tunnels. Plan VPN topology and static IP needs before you sign a 36-month circuit.

Next step: Size broadband for concurrent VPN sessions. Contact us for SD-WAN or ZTNA comparisons.

Full tunnel vs split tunnel

Full tunnel sends Netflix and Teams via HQ — simple for policy enforcement, expensive for bandwidth. Split tunnel sends SaaS direct to the internet; secure endpoints with disk encryption, EDR and conditional access instead of brittle “all traffic through VPN”.

Site-to-site and legacy apps

Warehouse ↔ head office replication may still need IPsec with predictable MTU/MSS. Document Phase 1/2 timers; avoid double-NAT where possible. Multi-site readers should skim SD-WAN guide.

ZTNA vs classic VPN

Zero-trust network access publishes individual apps, not whole subnets — smaller blast radius once laptops are compromised. It does not remove the need for good upload headroom where hairpinning persists.

Resilience

Dual-WAN or cellular failover keeps tunnels up during Openreach faults; test failover quarterly, not on the day payroll is due.
