Description
In general, it's very difficult for users to learn on their own why direct connections aren't working. We provide tools likecoder netcheck andcoder ping which seem designed for our engineers than end users. For example, these are the first few lines ofcoder ping -v:
I ~ coder ping c0 -v2024-08-12 17:06:44.261 [debu] net.wgengine: [v1] using fake (no-op) tun device2024-08-12 17:06:44.261 [debu] net.wgengine: [v1] using fake (no-op) OS network configurator2024-08-12 17:06:44.261 [debu] net.wgengine: [v1] using fake (no-op) DNS configurator2024-08-12 17:06:44.261 [debu] net.wgengine: dns: using dns.noopManager2024-08-12 17:06:44.262 [debu] net.wgengine: link state: interfaces.State{defaultRoute=en0 ifs={en0:[10.0.0.21/24]} v4=true v6=false}2024-08-12 17:06:44.262 [debu] net.wgengine: [v1] couldn't create raw v4 disco listener, using regular listener instead: raw disco listening not supported on this OS2024-08-12 17:06:44.262 [debu] net.wgengine: [v1] couldn't create raw v6 disco listener, using regular listener instead: raw disco listening not supported on this OS2024-08-12 17:06:44.262 [debu] net.wgengine: magicsock: disco key = d:fb319b0d612d3eb52024-08-12 17:06:44.262 [debu] net.wgengine: Creating WireGuard device...2024-08-12 17:06:44.264 [debu] net.wgengine: Bringing WireGuard device up...2024-08-12 17:06:44.264 [debu] net.wgengine: wg: [v2] UDP bind has been updated2024-08-12 17:06:44.264 [debu] net.wgengine: wg: [v2] Interface state was Down, requested Up, now UpThe result is frustration for our customers that have to bring Coder engineers into support calls. Today I'm experiencing that frustration as my development environment is much slower than normal. I even have the privileged ability to ping@coadler on Slack that our customers lack.
The most common question is "why isn't p2p working" and "what can I do to make p2p work". Can we design our various networking UIs in the product to explain that?
Here'scoder ping today:

- it's disabled as a deployment setting
- both sides of the connection are hard nat
