    全都连到中继节点了
    windows active; relay "tok"
    延迟有 400 多 ms,完全没办法用了

    点对点直连必须要求双方网络全都是全锥型吗?还是只有一方是全锥型就好了

    应该还是自己的网络环境问题吧

    NAT1 → Full Cone NAT
    NAT2 → Address-Restricted Cone NAT
    NAT3 → Port-Restricted Cone NAT
    NAT4 → Symmetric NAT

    理论上, 只要两者不为 3/4 或者 4/4 就可以做到点对点直连, 虽然成功率各不相同
    只要有一方是 NAT1 就很容易打洞
