Vyatta VPN IPsec 隧道随机掉线

我的 VPN 隧道不断随机中断，这种情况很少发生（大约一周两次​​），如果我执行“service ipsec restart”，它就会立即重新开始工作。真的很烦人，因为我试图将一个大型虚拟机复制到我们的 DR 站点，每次隧道中断，我都必须重新启动！

配置如下。大家有什么想法吗？

esp-group DR {
         compression disable
         lifetime 3600
         mode tunnel
         pfs enable
         proposal 1 {
             encryption aes128
             hash sha1
         }
     }


 ike-group DR {
         dead-peer-detection {
             action restart
             interval 15
             timeout 30
         }
         lifetime 28800
         proposal 1 {
             dh-group 2
             encryption aes128
             hash sha1
         }
     }



peer *.*.*.* {
             authentication {
                 mode pre-shared-secret
                 pre-shared-secret ***
             }
             connection-type initiate
             description "DR Site"
             ike-group DR
             local-address *.*.*.*
             tunnel 2 {
                 allow-nat-networks disable
                 allow-public-networks disable
                 esp-group DR
                 local {
                     prefix 192.168.*.0/24
                 }
                 remote {
                     prefix 10.*.0.0/24
                 }
             }
         }

检查日志后，它们似乎充满了以下消息：

答案1

我发现对隧道稳定性有很大帮助的设置是

set vpn ipsec auto-update '60'

我的死对等检测间隔和超时比您的长（分别为 30 秒和 120 秒），并且我使用了 VTI，但您的配置几乎与我的相同。我能够通过 VyOS VM 内的隧道维持 400 Mbps 的速度，没有任何问题。

答案2

抱歉，无法发表评论，这不是真正的答案：

  • 您是否尝试过增加该ike-group DR dead-peer-detetion timeout值？
  • 是否有可能每周随机出现两次网络使用高峰，从而饱和所有可用带宽？
