WAN Stands for "Wide Area Network", and is the terminology used to describe networking on a geographical scale.
A router in a WAN (Wide Area Network) or LAN (Local Area Network) is to allow access onto the Wide World Web (WWW).
A router.
A dual wan router combines two network connections into one. Cisco and Netgear both offer these models of router.
Yes it is.
The places to purchase a Dual-Wan router are many and varied. The best place to start would be Amazon. If you are on a tight budget, a good place to try would be eBay.
Take a look at the back of your router. It typically will be labeled "WAN". Refer to your user manual for detailed information.

A cascaded router because is a router connected to another router. As far as I know, there's two ways you can connect two routers together. One is from a LAN port to the WAN port of the other router and the other is LAN port to LAN port. LAN to WAN is useful for things such as network segmenting, say that you want the LAN of the first router not to be able to see the LAN of the second router. That can work. Whereas with the second way, the second router pretty much becomes a switch and you can have access to devices on both networks without the need for port forwarding. Consider it acting as a swithc with a IP address pretty much. However in this method you have to make sure the LAN IP of the second router is within the same subnet as the first in order for this to work. So let me give you a example of how it can be setup: LAN to WAN: Router A WAN IP: Issued from ISP (Usually through DHCP) LAN IP: 192.168.1.1 Subnet Mask: 255.255.255.0 Router B WAN IP: Issued from the DHCP server of the first router or can be statically set to be a address within the first routers LAN LAN IP: 192.168.2.1 Subnet Mask: 255.255.255.0 Note: With this method, computers on Router B can connect to devices on Router (including the router itself) but not vice versa. Also...you cannot access computers via NetBIOS names (computer names) in this setup. You have to access them by their client LAN IP LAN to LAN Router A WAN IP : Issued from ISP (Usually through DHCP) LAN IP: 192.168.1.1 Subnet Mask: 255.255.255.0 Router B WAN IP: Not used since nothing is connected to the WAN port LAN IP: 192.168.1.254 Subnet Mask: 255.255.255.0 Hope this helps you out. :)
ISR router will do lot of services compared with normal router. For example terminating VPN Sections, VoIP support, and bridging LAN/WAN cards. Basically ISR routers are modular routers, you can insert WAN T1/E1, SONET, etc cards. - kumar
Typically a LAN is connected to other networks (WANs, etc) via a router, used as a default gateway device.
