Tftp not reachable

[LukasGerm]

Hello,

I just tried pulling and running the container with an example file. When I tried to tftp localhost and get test.cfg I just get a timeout.

Apparently the connection from host to port 69 works but the tftp does not send any response.

Do you have any tips?

did you load the netfilter modules?

also, can you confirm that the container is bound to --- or available at --- the IP you're hitting with the client?

Okay I did not load the netfilter modules. I have to create a virtual machine. I am running it on macOs atm. Is it neccessary?

Yes. I checked, that the host is listening on port 69. I just used your commands.

The netfilter module has to be loaded on the Linux VM that runs the docker engine.
After that, does it work?

I ran modprobe now. I dont get a response from the server. It worked for me on Ubuntu Server. Now I am on ubuntu desktop and it does not work anymore. Do you have additional ideas?

I'm having the same issue here. I just found out that I need to use --network=host because tftpd response with random ports.
