  2. Default gateway - Wikipedia

    en.wikipedia.org/wiki/Default_gateway

    The default gateway can be specified by the route command to configure the node's routing table and default route. In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. It serves as the default gateway for all network devices.

  3. Gateway address - Wikipedia

    en.wikipedia.org/wiki/Gateway_address

    The gateway is on the same network as end devices. The gateway address must have the same subnet mask as host devices. Each host on the network uses the same gateway. The gateway should have a static address, as changing the address would cause packets not to be delivered. The gateway is typically assigned either the highest or lowest network ...

    Router and firewall for SMBs with network, gateway and server modules accessed through WebConfig. A paid registration for extra online services is available, but not necessary for operation of the product. Cumulus Linux: Active: Debian derivative? Free with registration, or paid subscription.

  5. Default route - Wikipedia

    en.wikipedia.org/wiki/Default_route

    The default route is generally the address of another router, which treats the packet the same way: if a route matches, the packet is forwarded accordingly, otherwise the packet is forwarded to the default route of that router. The route evaluation process in each router uses the longest prefix match method to obtain the most specific route.

  6. Static routing - Wikipedia

    en.wikipedia.org/wiki/Static_routing

    Static routing may have the following uses: When using static address configuration (in the absence of DHCP or Router Advertisements) it can be used to provide a default route, forming a special case of the longest prefix match as it has a prefix length of zero and therefore always matches, and always matches last.

  7. Open Shortest Path First - Wikipedia

    en.wikipedia.org/wiki/Open_Shortest_Path_First

    An ABR deletes type 4 and 5 LSAs from internal routers, sends them a default route of 0.0.0.0 and turns itself into a default gateway. This reduces LSDB and routing table size for internal routers. Modifications to the basic concept of stub area have been implemented by systems vendors, such as the totally stubby area (TSA) and the not-so ...

  8. 0.0.0.0 - Wikipedia

    en.wikipedia.org/wiki/0.0.0.0

    In routing tables, 0.0.0.0 can also appear in the gateway column. This indicates that the gateway to reach the corresponding destination subnet is unspecified. This generally means that no intermediate routing hops are necessary because the system is directly connected to the destination. [9]

  9. Network address translation - Wikipedia

    en.wikipedia.org/wiki/Network_address_translation

    If a packet is sent to 203.0.113.1 by a computer at 192.168.1.100, the packet would normally be routed to the default gateway (the router) [e] A router with the NAT loopback feature detects that 203.0.113.1 is the address of its WAN interface, and treats the packet as if coming from that interface. It determines the destination for that packet ...
