Comment (by cohosh):

 I talked to the pion webrtc folks about this and they pointed me towards
 this project:

 https://github.com/pion/transport/tree/master/vnet

 We might be able to use this to test different NAT topologies but it needs
 some work. The current
 [https://github.com/pion/transport/blob/master/vnet/nat.go NAT
 implementation] offers a few variations but not something like a symmetric
 or port restricted cone NAT, which is what we're running into issues with
 in #33666.

 Still it provides a good starting point. This ticket is going to take a
 lot of work.
