A static route forwards the data between NEs, or between a router and the computer where the U2000 Web LCT is installed.
Do not manually create an IP route because the IP route that is manually created has the highest priority. That is, NEs communicate with each other through the route that is manually created. If you incorrectly create an IP route, even if the IP route that is automatically created is good, the communication fails because the NEs communicate with each other through the route that is manually created.
