怎么可能不支持域名地址?你指的是内网域名 endpoint 吗?

支持域名,不支持动态域名

检查对方 A 记录是否更新,更新即重启 wg

@PatrickLe @ghostwwg 续上,如果你的胃联通支持 bash
#!/bin/bash REMOTEIP = $( nslookup your.domain.name | tail -n +3 | sed -n 's/Address:\s*//p' ) if [ ! -e /tmp/remoteip ]; then echo "${REMOTEIP}" > /tmp/remoteip fi OLDIP=`cat /tmp/remoteip` if [ "$REMOTEIP" != "$OLDIP" ]; then echo "${REMOTEIP}" > /tmp/remoteip wg-quick down wg0 && wg-quick up wg0 fi |

如果是用 openwrt 作为 WG 的网关路由,在 21.02 之后的版本里,官方(注意是官方,第三方的譬如 lean 的库不知道有没有)自带 peer 动态域名保活脚本,位置在
`/usr/bin/wireguard_watchdog` 自己看看就知道是什么原理了 |

写个 wg 保活脚本,ping 不通对端了就重启隧道
#!/bin/sh ping -W1 -c 3 10.0.7.1 > /dev/null if [ $? -eq 0 ] then date >> /tmp/wg-check echo "wireguard connection check success." >> /tmp/wg-check else date >> /tmp/wg-check echo "wireguard connection check failure. restart wireguard" >> /tmp/wg-check ifdown wg0 ifup wg0 fi |

@evalfun 太粗暴了,要知道可能连多个 peer ,而多个 peer 不是同时换 ip ,你重启接口全部影响了

如 12#所说,改过一版,基本只替换了 luci 读配置那些东西。

See: https://wiki.archlinux.org/title/WireGuard
After resolving a server's domain, WireGuard will not check for changes in DNS again. If the WireGuard server is frequently changing its IP-address due DHCP, Dyndns, IPv6, etc., any WireGuard client is going to lose its connection, until its endpoint is updated via something like wg set "$INTERFACE" peer "$PUBLIC_KEY" endpoint "$ENDPOINT". Also be aware, if the endpoint is ever going to change its address (for example when moving to a new provider/datacenter), just updating DNS will not be enough, so periodically running reresolve-dns might make sense on any DNS-based setup. Luckily, wireguard-tools provides an example script /usr/share/wireguard-tools/examples/reresolve-dns/reresolve-dns.sh, that parses WG configuration files and automatically resets the endpoint address. One needs to run the /usr/share/wireguard-tools/examples/reresolve-dns/reresolve-dns.sh /etc/wireguard/wg.conf periodically to recover from an endpoint that has changed its IP. One way of doing so is by updating all WireGuard endpoints once every thirty seconds[6] via a systemd timer: /etc/systemd/system/wireguard_reresolve-dns.timer [Unit] Description=Periodically reresolve DNS of all WireGuard endpoints [Timer] OnCalendar=*:*:0/30 [Install] WantedBy=timers.target /etc/systemd/system/wireguard_reresolve-dns.service [Unit] Description=Reresolve DNS of all WireGuard endpoints Wants=network-online.target After=network-online.target [Service] Type=oneshot ExecStart=/bin/sh -c 'for i in /etc/wireguard/*.conf; do /usr/share/doc/wireguard-tools/examples/reresolve-dns/reresolve-dns.sh "$i"; done' Afterwards enable and start wireguard_reresolve-dns.timer |

openwrt 有专门自动化 wireguard 的软件 unetd ,
你安装 luci-proto-unet 后使用,使用方法 https://openwrt.org/docs/techref/unetd 。小白还是建议上 zerotier. |
