For details about server polling, see Server Polling.
Type an IPv4 address range if the server is pure IPv4, or an IPv6 prefix and length if the server is pure IPv6.
When any agent’s IP address matches an IP address in the range, the agent applies the heartbeat and server polling settings and the server treats the agent as part of the unreachable network.
Agents with an IPv4 address can connect to a pure IPv4 or dual-stack OfficeScan server.
Agents with an IPv6 address can connect to a pure IPv6 or dual-stack OfficeScan server.
Dual-stack agents can connect to dual-stack, pure IPv4, or pure IPv6 OfficeScan server.
Trend Micro recommends that the server polling frequency be at least three times the heartbeat sending frequency.
