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 ...

A residential gateway connects a local area network (such as a home network) to a wide area network (such as the Internet). Models in this series use one of various 32-bit MIPS processors. [1] All WRT54G models support Fast Ethernet for wired data links, and 802.11b/g for wireless data links.
To allow a 6to4 host to communicate with the native IPv6 Internet, it must have its IPv6 default gateway set to a 6to4 address which contains the IPv4 address of a 6to4 relay router. To avoid the need for users to set this up manually, the anycast address 192.88.99.1 used to be allocated. [ 4 ]
