Public Ip Address; Enterprise Networks, Firewall - Ubisys G1 Assembly And Commissioning Instructions

Section 3 | Gateway G1 Configuration
Caution: Do not direct the TCP port 80 for the web interface! If you need access to the web interface when
being on the road, set up a secured VPN connection, if necessary.
Depending on the configuration, port forwarding is done either via name (gateway uses DHCP) or via IP address
(gateway uses a static address).
Follow these steps:
1. Open the configuration interface of your router. Usually, it is opened via the web browser. If necessary, read
the documentation of your router.
2. Set up port forwarding for the TCP port 8888. This can be configured under NAT (Network Address Trans-
lation) and the port rules of the router.
Example:
a.) Port forwarding via name: TCP Port 8888 (public) -> ubisys-g1
b.) Port forwarding via IP address: TCP Port 8888 (public) -> 192.168.xxx.xxx Port 8888 (local),
with 192.168.xxx.xxx being the static IP of the gateway.
ubisys-g1 is the host name of your gateway and can be changed in the configuration interface under network settings.

Note: You can operate more than one gateway in a local network. For external access, then, you select ano-
ther port than the default value 8888 for the public side, e.g. TCP port 8889 (public) -> ubisys-g1 port 8888.
For some routers, this function is called port forwarding and it has its own menu item in the router's configura-
tion interface.

3.10.2 Public IP address

In order for your app to find the router in the internet, the public IP address of your router has to be known. If
your router has a static IP address, you can skip this part and continue with the next section "Configuring the
app".
If the router has a volatile public IP address, which is the case with most DSL connections, you require a ser-
vice, such as DynDns or no-ip. On every internet login, these services automatically generate a so called DDNS
entry for your router. In the router, the DDNS provider has to be configured (dlinkddns, for example, is a free
version of DynDns for owners of a D-Link routers; no-ip is free as well for private usuage.). If necessary, read the
documentation of your router to determine, which options are or available or check the support forums of your
router manufacturer.
If your router has nonpublic IP address from the private IP pool (carrier-grade NAT), which is the case with most
LTE routers, you have the option to set up a VPN tunnel to a server with a static IP address. For determining the
best course of action, visit the support forums of your LTE provider or router manufacturer.

3.10.3 Enterprise networks, Firewall

If your network is protected by a firewall, as is often the case with corporate networks, make sure that an ex-
ception rule for incoming data traffic on port TPC 8888 is defined in the firewall configuration. Otherwise the
firewall will block any connections between mobile end devices with the ubisys Smart Home app and your Smart
Home gateway.
If you want to use the gateway in a corporate network managed by a network administrator, contact your net-
work administrator to obtain the recommended network settings for your company.
