Connect to a server with a specific interface

[jadiaheno]

Hi,

Is there a way to make the piko agent connect to the server with a specific interface? My use case is that the server is available only through the LAN interface, not WIFI.

Im happy to open a PR.

Thanks.

Hey @jadiaheno, thanks for opening this issue

Shouldn't Linux select the correct interface automatically in that case?

If not, would an optional --connect.bind-addr work for you, such as specify --connect.bind-addr 192.168.1.100 to select the interface (and optional port)?

Your welcome to have a go yourself (I can suggest what parts of the agent need updating), or I can add this weekend

Hey @andydunstall, thanks for your quick answer.

An optional --connect.bind-addr would work. Can you tell me where to add it?

Thanks.

Sure, so:

• Extend ConnectConfig in https://github.com/andydunstall/piko/blob/main/agent/config/config.go#L227
• Add BindAddr to https://github.com/andydunstall/piko/blob/main/client/upstream.go#L31
• Pass the bind addr to https://github.com/andydunstall/piko/blob/main/pkg/websocket/conn.go#L104 (which may need a custom dialer to pass the bind address)

As mentioned I'm happy to add this weekend as it will require changes to quite a lot of places, up to you

@jadiaheno are you still planning to work on this?

Otherwise if it's not needed can I close this issue?
