Unexpected 'Connection Timeout' When Using WireGuard VPN on Ubuntu 22.04 with Split Tunneling
I'm trying to debug I've been struggling with this for a few days now and could really use some help. Hey everyone, I'm running into an issue that's driving me crazy. I've searched everywhere and can't find a clear answer. I'm running a WireGuard VPN on an Ubuntu 22.04 server and have configured it for split tunneling. Everything seems to be set up correctly, but I'm experiencing a 'Connection Timeout' behavior when trying to access specific local resources. My `wg0.conf` file looks like this: ```ini [Interface] PrivateKey = <my_private_key> Address = 10.0.0.1/24 ListenPort = 51820 [Peer] PublicKey = <peer_public_key> AllowedIPs = 10.0.0.2/32, 192.168.1.0/24 Endpoint = <peer_address>:51820 PersistentKeepalive = 25 ``` The allowed IPs include both my client's IP and a local subnet. However, when I attempt to ping any IP within the 192.168.1.0/24 range, I get a timeout. I've ensured that the firewall rules on both the server and client allow for WireGuard's UDP traffic, and I've confirmed that the client configuration is properly set up as follows: ```ini [Interface] PrivateKey = <client_private_key> Address = 10.0.0.2/24 [Peer] PublicKey = <server_public_key> Endpoint = <server_address>:51820 AllowedIPs = 0.0.0.0/0, ::/0 PersistentKeepalive = 25 ``` Despite this setup, I can only access the internet through the VPN but not the local network. I've also tried restarting both the WireGuard service and the networking service with: ```bash sudo systemctl restart wg-quick@wg0 sudo systemctl restart networking ``` Is there something I'm missing in my configuration for split tunneling, or could it be an scenario with the network interfaces? Any insights would be greatly appreciated! My development environment is macOS. What's the best practice here? Any help would be greatly appreciated! My development environment is Ubuntu. Thanks in advance! Any ideas what could be causing this? Any help would be greatly appreciated!
