LAN routers on the Internet with the problem!

We also houses two computers, network management, but only the teacher Quarters bound to give us a physical address of the computer's IP, and another this is a local area network, Internet, but can not because the schools did not also bind the IP.I would like to ask this , To buy a router that allows two machines you have Internet access?

Will try my best, but to Inside the router to set up a static IP.Can
into your router 192.168.0.1

in the WAN settings
choose not to PPPoE, fixed IP address of the selected

and then fill in:
IP address of the subnet mask
Gateway
ISP address
main DNS server
secondary DNS server
you can buy a switch on the line .Should also be able to save you put on your computer that bind with the Gateway computer Gateway, you have to bind the IP that computers in the same segment.It's bound to have a computer DNS , Then you have told the same.Should be able to just bind, not every time the Internet will be able to verify all.

Into the router, I set the WAN, the choice of a fixed IP address before Internet access that computer's IP address, because the binding of IP, and IP is the network card in the address-tied, so the routing of the MAC address to be changed before the Internet can be the same as the MAC address.Taiwan before it can be The Internet address of the computer's MAC is also necessary to look to.

General routing of IP address 192.168.1.1 (also 192.168.1.0.1), you have two quarters of a computer based on IP as 192.168.1.2 ~ 192.168.1.254 between one will do.Router gateway is the IP address 192.168.1.1, DNS for you before that Taiwan can access the computer's DNS.

Attention:WAN routing is the mouth Outside the port, LAN port that is below your computer into the junction interface.
WAN port and LAN port is best not to the same IP paragraph (I tried the same paragraph on the IP network can not).
