Proxmox主机作为WireGuard客户端无法连接至服务器的问题求助

我现在想把我的Proxmox主机配置成现有WireGuard服务器的客户端，这样就能从家里以外的网络访问它了。

我参照Debian 11的WireGuard客户端配置流程操作后，执行了以下命令：

systemctl enable wg-quick@wg0.service
systemctl start wg-quick@wg0.service

虽然服务状态显示Active: active (exited)，但服务器端完全看不到任何连接请求。

下面是执行systemctl status wg-quick@wg0.service得到的输出：

● wg-quick@wg0.service - WireGuard via wg-quick(8) for wg0

执行wg命令查看WireGuard状态的输出：

interface: wg0
public key: tgiehhoZKLHNCjebdsf64uyIgTUQNVJiXahPEYVBcH0k=
private key: (hidden) listening port: 58649
peer: 8bfBMSRm2emrzchft6356dgm2UggkPbeStfwE7UdLi4=
endpoint: 12.187.257.16:1194
allowed ips: 0.0.0.0/1, 128.0.0.0/1, ::/1, 8000::/1
transfer: 0 B received, 1.59 KiB sent

我的wg0.conf配置文件内容如下：

[Interface]
# specify private key for client generated on WireGuard server
PrivateKey = XXXXXXXXXXXXX
# IP address for VPN interface
Address = 10.198.273.61

[Peer]
# specify public key for server generated on WireGuard server
PublicKey = XXXXXXXXXXXXX
# IP addresses you allow to connect
# on the example below, set WireGuard server's VPN IP address and real local network
AllowedIPs = 0.0.0.0/1, 128.0.0.0/1, ::/1, 8000::/1
# specify server's global IP address:port
# (acutually, example of IP below is for private range, replace to your own global IP)
EndPoint = 103.16.54.18:1194

整个过程没有任何报错，但服务器端就是看不到连接。而且完全相同的客户端配置在Windows 11上是可以正常连接的，这就很困扰我。

有没有大佬能帮我分析下问题出在哪？
