Tunnel Internet traffic

[lpm11]

Hi,

I have a router with Gargoyle and want to redirect all Internet traffic to OpenVPN tunnel and have some questions:

1. There is an option "Block Non-OpenVPN traffic" in VPN client configuration. Does it mean that traffic is automatically tunelled?
2. What is the TLS-Auth key?
3. Does the option "Credential Re-Use:" set to "Credential are specific to each client" make impossible for client to change IP?
4. Could I exclude some IP from "Block Non-OpenVPN traffic" option?

I am asking, because on the tunnel end there is a Linux Server, not Gargoyle router.

I didn't answer because I wasn't sure myself

My best guess the the answers

1. There is an option "Block Non-OpenVPN traffic" in VPN client configuration. Does it mean that traffic is automatically tunelled?

yes, in theory?

2. What is the TLS-Auth key?

3. Does the option "Credential Re-Use:" set to "Credential are specific to each client" make impossible for client to change IP?

What does it matter? It works with all IP address (depending on you setup)

4. Could I exclude some IP from "Block Non-OpenVPN traffic" option?

Not from the GUI, command line anything is possible (but not always easy)
