Teamviewer QuickSupport does not work the first time it is used if firewall allows outgoing traffic to www.teamviewer on port 443 and 80 + port 5938 but with the rest blocked.
It does however work if you in the firewall enable all outgoing trafic.
There seems to be some problem with the knox-license, so I tried to add these rules
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d www.samsung.com --dport 443 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d www.samsung.com --dport 80 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d www.samsungknox.com --dport 443 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d www.samsungknox.com --dport 80 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d docs.samsungknox.com --dport 443 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d docs.samsungknox.com --dport 80 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d developer.samsung.com --dport 443 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -p tcp -d developer.samsung.com --dport 80 -j ACCEPT &&
iptables -t mangle -A FORWARD -i wlan0 -j DROP [line 1111]
but that did not work either
teamviewer does work if you drop the last [1111] line. But that is not allowed we want to limit
the internet.
