Hi Jan, thanks for the answer and sorry for my delai to answer. I modified my config and reload the config (is it sufficient ? I can't restart the gatekeeper these days as it's in use) but I'm still having error messages : 2012/09/27 13:57:05.179 3 ProxyChannel.cxx(7242) RTP 193.49.144.129:63066<=>0.0.0.0:18230<=>172.16.7.76:3232 Error(0): Input/output error (12:111) or 2012/09/27 13:58:53.871 3 ProxyChannel.cxx(7189) RTP 193.49.144.129:63034<=>0.0.0.0:18248<=>0.0.0.0:0 socket has no destination address yet, 31 bytes queued 2012/09/27 13:58:53.871 3 ProxyChannel.cxx(8848) Proxy 193.49.144.129:63034<=>0.0.0.0:18248<=>0.0.0.0:0 forward blocked My network configuration is classical : Internet <--> firewall <--> gatekeeper with public IP <--> M100 installed on a windows with a private IP My config is bellow.
