The UDP port to send traffic out on is chosen mostly at random by the kernel
(GNUnet does as far as I recall not specify that 2086 should be used for
outbound traffic). I don't know if we should. It could also be NFS traffic if
your home-directory is on an NFS volume and gnunetd accesses files.
How blocking the traffic can not cause problems, well, if you're only blocking
parts of gnunet's traffic, the protocol is resistant to attacks in the sense
that it will still eventually get through. Only if you block all your inbound
or outbound traffic your node will stop to be operational. But of course,
blocking gnunet traffic will reduce the efficiency of your node.
Why is this an issue anyway?
