bootnode works for local nodes but not for nodes from another machine #30420

Hi, i am trying to work with the built-in bootnode (dev bootnode) in geth,

while the nodes on the SAME PHYSICAL MACHINE (lets say node A) can easily find each other with the bootnode

i run into an issue, when i try to connect a node that is present on a DIFFERENT PHYSICAL MACHINE (lets say node B),

that node cannot connect to this bootnode on Node A, even though i have used extip parameter to bind the bootnode to the public ip, with node 30301

here's the screenshot of the error given by the bootnode logs,

how can i resolve Bad discv4 packet error (and what does "too small" indicate?)

Are node A and node B on the same local network? Or are they both behind separate natted networks? Please provide some details about your network setup.

Could you please also give us the public ips and ports?
