Hello, I am using wireguard to connect two machines. My local server is connected to the internet via a router. I am using theis Server also for connecting other devices (e.g. mobile phones) to my home network. This works great.
But when connecting to another server (both debian 10), I only get a successful connection, but no ping. *My server:* wg show interface: wgnet0 public key: xxxxx= private key: (hidden) listening port: 51820 peer: sdfsdfsdfsdfsdfsdf= endpoint: 109.41.64.83:15167 allowed ips: 10.192.122.2/32 latest handshake: 1 minute, 7 seconds ago transfer: 10.95 MiB received, 40.35 MiB sent peer: yyyy= endpoint: 185.22.142.254:51380 allowed ips: 10.192.122.3/32 transfer: 0 B received, 5.20 KiB sent peer: yyyy= endpoint: 93.214.229.137:64119 allowed ips: 10.192.122.4/32 peer: yyyy= endpoint: 93.214.225.116:49819 allowed ips: 10.192.122.5/32 peer: yyyy= allowed ips: 10.192.122.6/32 peer: yyyy= allowed ips: 10.192.122.7/32 more /etc/wireguard/wgnet0.conf [Interface] Address = 10.192.122.1/24 SaveConfig = true PostUp = iptables -A FORWARD -i wgnet0 -j ACCEPT; iptables -A FORWARD -o wgnet0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE PostDown = iptables -D FORWARD -i wgnet0 -j ACCEPT; iptables -D FORWARD -o wgnet0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE ListenPort = 51820 PrivateKey = aaa= [Peer] PublicKey = yyyy= AllowedIPs = 10.192.122.2/32 Endpoint = 123.41.67.233:18314 [Peer] PublicKey = xxx= AllowedIPs = 10.192.122.3/32 Endpoint = 123.22.142.254:51380 ip route default via 192.168.177.1 dev eth0 proto static 10.192.122.0/24 dev wgnet0 proto kernel scope link src 10.192.122.1 and the other side/server: interface: wgnet0 public key: xxxxx= private key: (hidden) listening port: 54004 fwmark: 0xca6c peer: yyyyy= endpoint: [2003:cb:aaa:bbb:9ec7:a6ff:fefd:3a6d]:51820 allowed ips: 0.0.0.0/0 transfer: 0 B received, 2.75 KiB sent persistent keepalive: every 25 seconds more wgnet0.conf [Interface] Address = 10.192.122.3/32 PrivateKey = xxxxx= [Peer] PublicKey = yyyyy= Endpoint = v.myfritz.net:51820 AllowedIPs = 0.0.0.0/0 PersistentKeepalive = 25 It seems to me, that the connection is successfully established , but data is only transmitted in one direction. How can I find the reason? Regards, Hendrik
