Limit the set of UDP ports to use? #414

Open petterreinholdtsen opened 5 years ago

petterreinholdtsen commented 5 years ago

At work, incoming UDP packages with port below 50000 is blocked. The ones above 50000 is open do allow for SIP and other real time audio and video protocols.

What about adjusting opendht to restrict the range of ports used, to allow it to work also in such constrained environment?

Hi, OpenDHT works using a single UDP port, which can be configured. When using dhtnode use the -p argument to set the port to bind, when using dhtrunner the port to bind is passed to run().

Thanks. Note, this request is about changing the default port selection to increase the chance of getting OpenDHT to work out of the box. :)

Thanks to the suggestion, Do you know if this kind of port restriction is common ?

I do not know how common, but I know several large sites and company networks where such port restriction is in place.

Did someone change the default set of UDP ports? The site I know about is still blocking UDP ports. I have not tried to use Jami there for a long time, as it just did not work. Is there a point in trying again?
