DESCRIPTION:STUNMESH-go is an open-source tool that enables direct peer-to-
 peer WireGuard connections between devices behind NAT or CGNAT. It multipl
 exes STUN and WireGuard traffic on the same UDP port by interacting direct
 ly with the kernel WireGuard module\, avoiding the overhead of userspace p
 roxies. Originally Linux-only\, we ported STUNMESH-go to FreeBSD and macOS
 . This talk covers the technical challenges we encountered: adapting from 
 Linux raw sockets to BPF-based per-interface packet capture\, porting the 
 health monitoring and automatic reconnection system\, and ensuring the plu
 gin-based peer discovery mechanism works across platforms. We validated ou
 r work on OPNsense firewalls\, VyOS routers\, and mixed BSD/macOS/Linux fu
 ll-mesh topologies.
