About this Gig

WireGuard is fast and modern, but its minimal config leaves a lot of room for subtle mistakes that are hard to debug. I've worked extensively with WireGuard on Linux VPS environments and know exactly where things break.


What I cover:

  • Fresh WireGuard server setup on any Linux distro
  • Peer configuration and key exchange
  • Routing and NAT (PostUp/PostDown iptables/nftables rules)
  • Fixing handshake failures and timeout issues
  • NAT keepalive and peer persistence tuning
  • Split tunneling and selective routing
  • Integration with existing firewall rules


Common problems I fix:

  • Peers connect but no traffic flows
  • Handshake established but routing broken
  • VPN drops after idle period (NAT timeout)
  • Config works locally but fails on VPS


Send me your wg0.conf, your firewall rules, and a description of the issue. I'll find and fix the root cause.
