Strata CTX Programming - Part 2: CTX WinAdmin Programming 6/04
•
To setup CTX WinAdmin WAN and Internet connections using
Dynamic Host Configuration
Protocol
(DHCP), Virtual Private Networks (VPN), etc., the proper IP addresses and setup procedures
must be obtained from your Information Technology (IT) Administrator.
•
We recommend using VPN networking. By using VPN networking, the content of SNMP messages
between WinAdmin PCs and CTX systems will be encrypted for security.
•
When connecting CTX WinAdmin through Fire Walls, Routers, etc., which apply packet filtering,
make sure that the packets being sent between Strata CTX and CTX WinAdmin are not filtered.
•
Strata CTX and CTX WinAdmin communicate using SNMP over User Datagram Protocol/Internet
Protocol (UDP/IP) and FTP protocols. The standard ports are used for each protocol (161 and 162 for
SNMP, 20 and 21 for FTP). These ports should not be blocked by firewalls.
•
The default gateway IP address must be set up on CTX WinAdmin and on CTX processors per the
example in
Figure 3-3
. The figure below shows you how to connect the multiple CTX sites via the
WAN.
•
The CTX processor requires the following IP addresses set in Program 916:
•
Processor static domain IP address
•
Processor subnet mask
•
Processor default Gateway IP address
•
The diagram below is only one example of many network configurations allowing remote maintenance
of CTX systems over the Internet and the WAN.
