This Skill helps you diagnose why connectivity fails (routing, DNS, TCP/UDP reachability, MTU) and how to choose and troubleshoot the right censorship-bypass approach for your exact blocking type.
Ask the Skill to “Diagnose why my internet/website is blocked in Russia—here are tcpdump, Wireshark summaries, ip route/ip rule/ss outputs and the VPN configs—and tell me which bypass strategy and next commands to run.”

To diagnose VPN connectivity blocked in Russia, map observed symptoms to blacklist, whitelist, throttling, or protocol-block models using tcpdump summaries, ip route outputs, and Wireshark captures to pinpoint the blocking layer.
Selecting a censorship bypass protocol for DPI evasion requires mapping symptoms to likely block types to choose suitable technologies like AmneziaWG, Xray VLESS Reality, Hysteria2, or zapret tooling.
Troubleshoot MTU and TCP handshake failures using packet capture by applying practical Wireshark and tcpdump filters alongside TCP, QUIC, and WireGuard heuristics to pinpoint exactly where traffic breaks.
Yes, you can use iptables and nftables rules to identify Linux firewall blocking by triaging L3, L4, and L7 symptoms through routing, interface policy rules, and connection-state inspection.
Network connectivity fails despite correct DNS resolution when issues exist at the firewall, routing, MTU, or transport levels, requiring connection-state inspection and packet capture to identify the failing layer.
Use whitelist bypass routing layers or VK TURN instead of VPN protocols when DPI interference models indicate strict whitelist blocking rather than standard blacklist filtering or protocol throttling.
