How do I configure the Firewall for Wisenet SKY Bridges.

Applies to Models: All Wisenet SKY Bridge Hardware


The below article describes the steps to configure TCP and UDP firewall ports for Wisenet SKY Bridges.

Getting Started:

The following TCP and UDP ports are used by the Wisenet SKY Bridge. All connections are outbound-only, meaning that the bridge connects outbound and never accepts inbound connections (so you do NOT need to set up e.g. NAT rules as a general rule).

Port Description
80/tcp # Used to discover video termination endpoints in the cloud
443/tcp # Used to transfer video to the cloud (TLS 1.2+)
773/tcp # Used to transfer video to the cloud (TLS 1.2+)
8081/tcp # Used to transfer video to the cloud
8082/udp # Used to transfer video metadata to the cloud
50000-60000/tcp # Used occasionally to provide remote troubleshooting and maintenance (Secured via SSL)


Note: There can be no proxies or similar application-layer filtration devices between
the Wisenet SKY Bridge and the Internet, and multicast must be enabled so the bridge can
detect cameras (if the bridge and cameras are on the same subnet, generally this isn’t a
problem). UPNP is NOT required (the bridge won’t use it if enabled).
Note: For further information on the ONVIF camera discovery protocol we use, see this article
on WS-Discovery. Web Service Discovery is an OASIS industry standard and generally works
without much effort on most internal networks. You should not need to adjust your firewall
to get it to work unless there is additional firewalling between your bridge and cameras.

Outbound IPs for the Wisenet SKY Bridge:

Should you need to restrict the Wisenet SKY Bridge to a specific set of IP addresses, the following is the list of Wisenet SKY IP addresses you should allow in CIDR format:


Wisenet SKY Cloud VMS Wisenet SKY Camera Manager  


Outbound Ports for the Wisenet SKY Web and Mobile Applications:

Independent of the bridge, the Wisenet SKY Web and Mobile Applications for PCs, tablets, and phones also need to connect to the cloud to retrieve video, set settings, and so on. The ports required for this are:

Port Description
tcp/80 # HTTP->SSL Redirect Only
tcp/443 # Web user interface
tcp/50000-60000 # Secure video transfer


Note: The IPs are generally the same as for the bridge.
