Lightweight DTLS reverse proxy server based on tinydtls and libev.
Similar with goldy, but using tinydtls instead of mbed TLS, using pre-shared key (PSK) instead of certificate/private key files.
usage: dtlsproxy -l <host:port> -b <hosts:ports> -k <key maps>
-l listen listen on specified host and port
-b backends backend servers (host1:port1,host2:port2,...)
-k keys psk identities (id1:key1,id2:key2,...)sample usage:
$ dtlsproxy -l 0.0.0.0:5684 -b 127.0.0.1:15683 -k Client_identity:secretPSKTested on Cygwin and Ubuntu hosts with a libcoap server (on port 15683) as the backend.
