UDP Bus
tool to exchange UDP packets
android-udp-bus is an application to create UDP forwarders, hubs and other tools. To aid building VPNs, video streaming and other tricky network uses.
Features:
* Binding UDP socket on specified port and exchanging traffic between all known peers
* Exchanging traffic between multiple UDP sockets
* Remembering specified number of peers that have sent us some datagram, with optional expiration policy
* Directly specifying peers to send datagrams to. Combined with remembering, it allows using the application as UDP forwarder.
* Joining multicast groups, setting TTL, TOS, read and write buffer sizes and other socket options.
* Periodical sending of hardcoded datagrams to specified peers (e.g. to keep NAT open)
* Displaying of detailed statistics of the traffic
* Starting multiple isolated hubs, each with distinct set of ports. Can even act as a simplistic load balancer due to SO_REUSEPORT.
The application does not send datagrams back to sender.
Limitations:
* UI is not user-friendly.
* Not all features are exposed in GUI - you may want to add some undocumented fields to the JSON manually.
* Not very optimised for speed or latency. It may be slightly slower than socat udp4-l udp.
* Not everything is tested yet
* Documentation is lacking
