SKUDONET adds eBPF-based Last Hop to Enterprise Edition 10.2.2

SKUDONET has released Enterprise Edition 10.2.2, adding a feature called Last Hop that uses eBPF to preserve return paths in asymmetric routing environments. The update also brings HTTP and HTTP/2 enhancements, a refreshed WebGUI and multiple fixes across routing, certificates and traffic handling.

Why it matters: - Enterprise networks often split traffic across routers, firewalls, VLANs and redundant paths. - Last Hop is designed to keep return traffic on the right path when the technically valid route is not the path the connection originally used. - That can reduce dropped sessions, inconsistent NAT behavior and policy mismatches across network paths. - The feature also lowers the need for manual routing workarounds as ADC deployments span more services and more networks.

What happened: - SKUDONET released Enterprise Edition 10.2.2 of its Application Delivery Controller platform on October 1, 2026. - The main addition is Last Hop, an eBPF-powered capability that learns the Layer 2 path used by an incoming connection and preserves the matching return path. - The release also adds HTTP and HTTP/2 updates, a refreshed WebGUI and several traffic-management improvements.

The details: - Last Hop uses eBPF inside the Linux networking datapath to identify how a connection reached the ADC. - Linux still makes the normal routing decision for the response. - SKUDONET's eBPF logic then checks that decision after routing and corrects the output when the learned path calls for a different interface. - The feature is meant to replace or reduce static routes, Policy-Based Routing, source-specific routing and per-application routing rules. - Last Hop also supports environments where a backend server is also a client of another load-balanced Virtual IP. - Enterprise Edition 10.2.2 adds dynamic redirects that can reuse regular expression capture groups. - The redirect update lets administrators handle multiple URL migration scenarios with one rule. - The release adds configurable backend cookie values for consistent session affinity across compatible services. - The WebGUI has a refreshed visual design for configuration and monitoring tasks. - Additional improvements include CGI concurrency control and systemd integration for WebGUI process management. - The release also adds more detailed error logging when reading client or backend HTTP headers. - Internal performance optimizations are included to improve traffic-processing efficiency. - The update resolves issues affecting HTTP, HTTP/2, L4xNAT and certificate management. - Fixes include case-insensitive SNI hostname matching aligned with RFC 6125. - The release also improves handling of special characters in redirect URLs. - Maintenance actions for unavailable backends are corrected. - WebGUI certificates now update automatically after Let's Encrypt renewals.

Between the lines: - Last Hop targets a common enterprise networking problem where routing works in theory but breaks stateful traffic in practice. - The eBPF approach pushes path correction into the ADC itself, which may simplify deployment for teams trying to avoid broader network redesigns. - The added HTTP and WebGUI changes suggest SKUDONET is broadening the release beyond routing into day-to-day operator workflow.

What's next: - SKUDONET says the platform is built for on-premises, virtualized, cloud and hybrid environments. - The company is positioning Enterprise Edition 10.2.2 for larger and more segmented ADC deployments where routing state and application traffic intersect. - More information is available through SKUDONET Enterprise Edition.
