hi im trying to set up my cisco lab to access the internet through my virgin home router,i have turned on modem mode and it gives my router 1 an ip add,i have also set up nat with overload,i also see the route in my routing tables of other routers. frim pc 3 that is right across the other side of the network i can ping 4.2.2.2 but not google.com,from my r1 which is the router connected to my modem i can ping 4.2.2.2 and google.com no problem,and when i do sh ip nat translations it shows the nat working,but non of the pcs can get any web pages.also have default route to internet interface,no other access-lists just the nat any ideas

also from all pcs i can type in ip add into web browser and access the site,on each router i have done the command ip name server 4.2.2.2

thanks tewy

Hi Chris,

Are your PCs able to use a DNS server, did you set a DNS server on ur PCs or have the option set, in case of using DHCP server for addressing?

plz Rate if it helped,

from the pc, can you ping to 8.8.8.8 ? if yes, then try to change your dns to this ip. its google's dns
