If I use the same configurations and connect using “Global Proxy”, I do not get these error messages and traffic is directed over the tunnel. No traffic flows over the tunnel, all DNS and internet traffic go outside the tunnel. I don’t have access at the moment to the Beryl log, but on its side I get three error messages about “no such program”. When the Beryl connects using “Auto Detect”, these server messages are logged:īerylAX/ip.ip.ip.ip:35163 SENT CONTROL : 'PUSH_REPLY,route 192.168.50.0 255.255.255.0 vpn_gateway 500,dhcp-option DOMAIN Workgroup,dhcp-option DNS 192.168.50.1,redirect-gateway def1,sndbuf 512000,rcvbuf 512000,route-gateway 10.16.0.1,topology subnet,ping 15,ping-restart 60,ifconfig 10.16.0.3 255.255.255.0,peer-id 1,cipher AES-256-GCM' (status=1)īerylAX/ip.ip.ip.ip:35163 PUSH: Received control message: 'PUSH_REQUEST'īerylAX/ip.ip.ip.ip:48987 Inactivity timeout (-ping-restart), restarting In order, these tell the Beryl to route traffic to my server’s local lan through the tunnel advertise my server’s dns server to the Beryl, and redirect the gateway to the server.
