Hi. Thanks for the response.
The 7402VGO Firewall has different levels of protection that you can enable
* None
* Low Security
* Medium Security
* High Security
* All blocked / User Defined
I usually use Medium Security which adopts a restrictive plicy by blocking
all traffic except the standard ports such HTTP(80), FTP(21), SSL(443) etc.
You can open other ports if you want to.
When the firewall is set to Medium it is obviously interfering with
Messengers ability to open the necessary ports and video conferencing doesn't
work.
When the firewall is disabled (none), NAT is still enabled and video
conferencing does work.
I'd like to open as few ports as possible in order to get messenger working.
Can you specify the minimum ports and or ranges that need to be opened
(Inbound & Outbound) and what protocol (UDP/TCP) for each port?
Thanks.
