Fix Dropping SSH, Kubernetes & Git Sessions on Hyperoptic 1Gbps Full Fibre With Persistent WireGuard

Experiencing slowdowns or connection drops on Hyperoptic 1Gbps Full Fibre (AS56595 • FTTP / Ethernet CGNAT) during 19:30–23:00 UK? Aggressive CGNAT state timeouts, PPPoE MTU blackholes, and IPv6 route flaps terminate idle SSH terminals, `docker pull` layers, and `kubectl` port-forwards. SWEEPR VPN configures a 25-second `PersistentKeepalive` and path-matched MTU so SSH, database tunnels, and remote IDE sessions survive Wi-Fi/5G roaming without dropping.

Why Hyperoptic 1Gbps Full Fibre (AS56595) Suffers From With Persistent WireGuard

On Hyperoptic 1Gbps Full Fibre (FTTP / Ethernet CGNAT), residential and mobile gateways frequently encounter CGNAT session table saturation and transit peering congestion during evening peak hours between 19:30–23:00 UK. Standard unencrypted TCP/UDP flows expose plaintext Server Name Indication (SNI) headers, destination ASNs, and packet timing signatures that automated network queues classify and deprioritize.

Furthermore, using a default 1500-byte or uncalibrated VPN tunnel on Hyperoptic 1Gbps Full Fibre triggers IP packet fragmentation unless your WireGuard interface is pinned to MTU = 1420.

How SWEEPR VPN Solves This on Hyperoptic 1Gbps Full Fibre

Direct 10Gbps LINX & AMS-IX Peering: Instead of traversing congested retail transit links on AS56595, SWEEPR VPN routes your encrypted UDP stream directly to our 10Gbps RAM-only bare-metal nodes in UK-LON-01 (4ms), NL-AMS-01 (8ms), DE-FRA-01 (11ms), and SE-STO-01 (14ms).
Auto-Calibrated 1420 Byte MTU: SWEEPR VPN automatically detects FTTP / Ethernet CGNAT path overhead and clamps your WireGuard tunnel to MTU = 1420 with PersistentKeepalive = 25.
In-Tunnel Zero-Log DNS (10.66.0.1): Bypasses Hyperoptic 1Gbps Full Fibre transparent DNS proxies and NXDOMAIN interception completely.
Free 30-Second Home Wi-Fi Device Scanner: Instantly audits every phone, laptop, IoT plug, and Smart TV connected to your Hyperoptic 1Gbps Full Fibre router subnet.
