Hi,
from last week, I am having problems with skype. I am unable to hear voice when I make calls with skype.
for skype to work I need to have:
- All destination ports above 1024 (recommended)
or
- Ports 80 and 443
all port above 1024 are not open. but 80 and 443 are definitely open but skype is able to make call but iI can't hear sound.
I don't have L7 filtering.
when I open UDP port from 10240 to 64500 skype is working ok.
does someone have this problem?
in attachment is Wireshark capture of traffic, when call is not working - unable to hear sound (first call), and other call when UDP any any is allowed and I can hear both side.
So please help!
p.s. due to safety rules I can't open all ports :-(
Regards,
Ivan
