FR: Is there any way to relay traffic through the node? #15849

Description

@badgv

What are you trying to do?

There are the following usage scenarios:

1: Tailscale is installed on three node:
A 100.69.0.1(symmtric NAT)
B 100.69.0.2(Full Cone NAT)
C 100.69.0.3(symmtric NAT)

2: A and B can be directly connected, A ping B 10ms

3: B and C can be directly connected, B ping C 10ms

4: A and C can only relay traffic through derper,A ping C 200ms

Is there a way to auto relay the traffic between A and C through B by tailscale?

How should we solve this?

Consider adding parameters like --as-relay-server=true when starting a tailscale node, so that the node can be used as an "inside relay derper" for the tailscale internal network.

Other nodes can use similar parameters like --relaybynode=true to use a defined custom relay node.

What is the impact of not solving this?
