Whats a CRP server?
CRP is the Connection-Reflexion Protocol. A CRP client connects to a CRP server and the CRP server tries to connect back. JM uses CRP to check your network configuration. If the CRP server can connect back to you, then your network configuration is correct. CRP is something we designed – it’s not standard. This functionality will probably be intgrated into future versions of MTP and BTP.
