版本v2，tcp打洞后可以访问，过段时间（几个小时）就报这个错误： 2024-06-11 10:04:38 [I] tcp://192.168.3.7:22240 <--socket--> tcp://192.168.3.7:40993 <--Natter--> tcp://122.97.183.24:3207 2024-06-11 10:04:38 [I] 2024-06-11 10:04:38 [I] LAN > 192.168.3.7:22240 [ OPEN ] 2024-06-11 10:04:38 [I] LAN > 192.168.3.7:40993 [ OPEN ] 2024-06-11 10:04:38 [I] LAN > 122.97.183.24:3207 [ OPEN ] 2024-06-11 10:04:39 [I] WAN > 122.97.183.24:3207 [ OPEN ] 2024-06-11 10:04:39 [I] 2024-06-11 15:44:16 [E] fwd-socket: cannot forward port: Too many threads 2024-06-11 15:44:16 [E] fwd-socket: cannot forward port: Too many threads 2024-06-11 15:44:25 [E] fwd-socket: cannot forward port: Too many threads 2024-06-11 15:49:25 [E] fwd-socket: cannot forward port: Too many threads 2024-06-11 15:54:17 [E] fwd-socket: cannot forward port: Too many threads

Natter 的 socket 方法会限制线程数，self.max_threads 定为 128，防止系统资源耗尽。 如果服务需要大量并发连接，推荐改用 iptables 等其他方法。
