Wireguard tunnel in another wireguard tunnel?

[T-Bo4]

Is this possible to have two wireguard tunnels on the same network?

Let me give more details:

1. Both tunnels have been created with config files
2. Both should be connected to a different server/city
3. R2 is running like an access point

Let me know thanks!

What platforms are running the local and the remote endpoints?

Both routers are in the same house and are running ddwrt

R1 is close to modem and R2 is wired to R1 on the other side of the house

R1 wireguard tunnel is running amazingly to serv/city #1
I'm trying to set R2 to another serv/city for streaming but it doesn't work.

Maybe MTU issue?
