OpenVPN Replay-window backtrack occurred

OpenVPN admin 5143浏览 0评论

Sometimes network congestion and latency cause the UDP protocol, most commonly used with OpenVPN, to drop packets and even lose the connection. You will see a ‘Replay window backtrack occurred’ error in the log if this is occurring. One solution is to switch to the TCP protocol, assuming your server is configured to support a TCP connection.

在使用UDP协议的时候,如果网络不稳定,偶尔会出现丢包问题,或者分包错误,导致链接中断,

解决方法有两种,

一是修改 TCP 方式

[root@aikaiyuan ~]# cat /etc/openvpn/server.conf | grep proto
proto tcp
[root@aikaiyuan ~]#

二是修改MTU

添加 link-mtu 1400 参数

或者直接修改sys 配置

echo 1400 > /sys/class/net/tap0/mtu
echo 1400 > /sys/class/net/eth0/mtu
