For persistent issues, capture a Wireshark trace on the Hamachi interface filtering for inbound traffic (src net 5.0.0.0/8) and analyze for ICMP unreachable or TCP RST packets.
| Factor | Impact on Hamachi Inbound | |--------|----------------------------| | Symmetric NAT | Blocks UDP hole punching; forces relay | | ISP-level CGNAT | Prevents direct inbound; only relay works | | Double NAT | Same as symmetric NAT | | UPnP disabled | Hamachi cannot auto-forward ports | hamachi inbound traffic blocked

Report ID: HAM-2024-INT-001 Date: April 14, 2026 Subject: Persistent blocking of inbound traffic on Hamachi network adapters Target Audience: Network administrators, IT support specialists, Hamachi power users 1. Executive Summary LogMeIn Hamachi is a zero-configuration VPN that facilitates virtual local area networks (VLANs). However, a pervasive issue reported across Windows, macOS, and Linux clients is the blocking of inbound traffic — where a peer can send data out (egress) but cannot receive data from other network members (ingress). This report analyzes the root causes, diagnostic methods, and comprehensive solutions for inbound traffic blocks in Hamachi environments. 2. Problem Definition Symptom: A Hamachi client shows as "online" and can ping other members, but other members cannot ping or establish connections to this client. File sharing, remote desktop, and game hosting fail from this peer. -t From local peer:
ping <local_hamachi_ip> -t From local peer:
