Dear List, I'm having trouble to connect my cam/mic to my external server when connecting from my workplace, Maxim assumed that my workplaces-it-service blocked some important ports. I did the following to test it.
1) opening up port 49152 on my server ls | nc -l -u -p 49152 2) from home (om is running smoothly) sudo nmap -sU <server-ip> -p 49152 command under 1) quits and nmap responds with Host is up (0.016s latency). PORT STATE SERVICE 49152/udp open unknown 3) from my workplace-pc first: issuing command 1). second: sudo nmap -sU <server-ip> -p 49152 response: Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn third: sudo nmap -Pn -sU 81.169.223.177 -p 49152 response PORT STATE SERVICE 49152/udp open|filtered unknown Does it confirm the assumption, that some workplace-firewall-rule blocks my way ? Have fun and many many thanks, Kaffeesurrogat
