After configuration, you can reach web server OZW775 via Internet from anywhere
(worldwide).
For HTTP web pages (incoming Internet data) you do not need to explicitly enter public
port 80 in the Internet address. All other ports must be specified explicitly, however.
In a local network, the static IP address of the web server is used to access web server
OZW775.
Use the diagnostic information in Section 6.2.3 if you cannot reach web server
OZW775.
7.2.5 Example 2: Corporate network topology
You want to connect web server OZW775 in a corporate network with 1...x branches to
monitor the HVAC plants at all branches. You want to access each web server via a
static IP address or via a domain name.
Discuss the project together with the network administrator and get the following
information:
•
IP address
•
IP subnet mask
•
Default gateway
•
Company-internal mail server
•
Company-internal DNS server
1)
•
Company-internal domain name
1)
1)
A company-internal DNS server is necessary if you want to access the web server OZW775 via
domain names and not via static IP address.
Request the domain names from the network administrator if you also want to access
the web servers OZW775 via domain names.
