Remote connection
The merger allows to log in to device from an external network via the
internet, for this purpose it should be:
•
have an external IP address on the router assigned by the internet
provider and be able to establish connection from outside (incoming
packets are not blocked by the provider’s and router’s firewall),
•
redirect port 80 to the IP address of the merger working in the local
network (so-called forwarding port),
•
unblock selected port in the router’s firewall,
•
the address of the merger / mergers in the local network can not
change (the merger must have a static IP address set or the DHCP
server must assign the same addresses to the same devices each
time).
NOTE! The destination port of the device is always port 80, for added security
it is recommended to redirect other ports from the external network to port 80
in the local network.
Example: by sending a query to the external IP address of a router with port
number 12345 (e.g. 66.77.88.99:12345), the router will forward this query to
the address of the device with port number 80 (e.g. 192.168.0.50:80).
