我已经设置了 Wireguard。我可以在10.200.200.1Peer 2 上连接到 Peer 1 上的地址。但是，我无法连接到10.200.200.1Peer 1。我该怎么做？
对等体 1 的配置：
[Interface]
Address = 10.200.200.1/24
ListenPort = 51820
PrivateKey = ************
# substitute eth0 in the following lines to match the Internet-facing interface
# if the server is behind a router and receives traffic via NAT, these iptables rules are not needed
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -A FORWARD -o %i -j ACCEPT; iptables -t nat -A POSTROUTING -o enp0s2 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -D FORWARD -o %i -j ACCEPT; iptables -t nat -D POSTROUTING -o enp0s2 -j MASQUERADE
[Peer]
# foo
PublicKey = ***************
#PresharedKey = PRE-SHARED_KEY
AllowedIPs = 10.200.200.2/8
#PersistentKeepalive = 25
curl 10.200.200.1:2001给我
* Trying 10.200.200.1:2001...
* connect to 10.200.200.1 port 2001 failed: Connection refused
* Failed to connect to 10.200.200.1 port 2001 after 0 ms: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 10.200.200.1 port 2001 after 0 ms: Connection refused
10.200.200.1但我能 ping 通。

好的，我明白了——这有两个部分：
sysctl
sudo sysctl -w net.ipv4.conf.all.route_localnet=1
sudo sysctl -w net.ipv4.ip_forward=1
对于本地工作连接：
sudo iptables -t nat -A OUTPUT -d 10.200.200.1 -j DNAT --to-destination 127.0.0.1
