Abstract
A router includes a routing table containing flags each representing a public-network side or a LAN side. A path for a received packet is determined such that the packet is forwarded to the next node through the LAN according to the next node address when the flag corresponding to the specified destination represents the LAN side, and the packet is forwarded to the next node through the public network according to the next node address when the flag represents the public network side. When a change of the routing information sets is monitored, the routing table is searched for the second router having the flag representing the public network side and then the changed routing information sets are transmitted to the second router.
