Firewall settings

To let our conferencing solution work properly firewall must be configured according to following rules:

IP address

78.102.19.215 – ports TCP 80,443  – this is used for provisioning server. These ports need to be allowed by firewall. Also when using Windows XP there might be a prompt for certificate to be accepted. Please make sure you accept it.

78.102.19.217 and 78.102.19.222 – ports UDP 1194 (preferred) or TCP 443 – ports UDP 1194 (preferred) or TCP 443 – this is used for tunnel establishment between you and our server. All data flow through this tunnel so it is necesary to have these ports allowed by your firewall.

Program:

  • builds VPN tunnel to the public IP addresses.
  • assigns IP address 172.19.xxx.xxx to local TAP Win32 adapter
  • adds route 172.19.96.0 MASK 255.255.248.0 172­.19.xxx.xxx
  • adds route 78.102.19.200 MASK 255.255.255.248 172­.19.xxx.xxx
  • adds route 172.19.110.0 MASK 255.255.255.252 172­.19.xxx.xxx

78.102.19.201, 78.102.19.202, 78.102.19.207 – ports TCP 1720, TCP 3230 – 3243, UDP 3230 – 3285 – Inter-VPN communication with conferencing servers. The program communicates inside VPN tunnel with a conference server, the mere exchange of video and audio data.

Also, if you're using Proxy server, you should disable it for all IP addresses mentioned above.
