13.4.5 WAN connection
JP1/IM - Manager can be used on a WAN only if the line is always connected.
- Notes on connecting JP1/IM - Manager and monitored hosts
-
When you use JP1/IM - Manager in a WAN environment, we recommend that you consider communication speed and traffic and create a multi-level system configuration. The recommended configuration has from tens to hundreds of monitored hosts that are installed in each building or work place and that are connected to a LAN and a base manager located in the work place. Note the following when using JP1/IM - Manager in a WAN environment:
-
When JP1/IM - Manager monitors a log on a monitored host, it periodically communicates with the monitored host. Accordingly, we do not recommend that you connect JP1/IM - Manager and monitored hosts on a network that charges according to time or traffic (for example, an INS-P or INS-C WAN).
-
Timeouts might be frequent during communication between JP1/IM - Manager and monitored hosts.
-
Remote monitoring is disabled if the firewall located between the integrated manager and monitored hosts uses NAT static conversion. Be careful when a firewall is installed between the integrated manager and monitored hosts in a WAN environment. You can avoid this problem by adding an additional base manager on the monitored-host side. By doing so, NAT static conversion moves from the firewall between the integrated manager and monitored hosts to between the integrated manager and the additional base manager.
For firewall settings, see 13.4.4 Operation behind a firewall.

-
Notes the following when using JP1/IM - Manager in a WAN environment:
-
Because JP1/IM - Manager and JP1/IM - View periodically communicate with each other, we recommend that you do not connect JP1/IM - Manager and monitored hosts on a network that charges according to time or traffic (for example, an INS-P or INS-C WAN).
-
Communication timeouts might tend to occur between JP1/IM - View and JP1/IM - Manager. If this is the case, review the timeout periods set for communication between JP1/IM - View and JP1/IM - Manager.
