Installation
Step 2: Set Up LAN Connection to Strata CTX
• To setup CTX WinAdmin WAN and Internet connections using
Protocol
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
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.
