[Freeswitch-users] Dest./port unreachable for RTCP and first few RTP packages

Hello, While looking at some traces in Wireshark I noticed some packages which generated an "Destination unreachable (Port unreachable)" ICMP answer from my server. These where: - All RTCP packages - At least in one case the first few RTP packages in a new call (6 packages over around 0.12s, after that RTP worked) So my questions are: - Should I be worried about these? - What's the deal with RTCP packages? Can/should I simply ignore them or is there an option in freeswitch that I should set to handle them? Thank you, René
