I have a 2514 and I´m using both ethernet ports (config below).
One is attached to the LAN and the other to a cable modem with a FIXED ip address.
I can make the router see the internet (pings anything) by just adding the classic "ip route 0.0.0.0 0.0.0.0 (gateway´s ip address)"
The PCs can ping both of the router´s ethernet interfaces, but CANNOT go beyond that.
I know it´s a simple matter to solve (probably just another "ip route" command) and thus I thank you!

No, I do not own the address 189.57.etc
But since I´m a total ******* when it comes to routing I guess that means I did not know I just can´t use that address and have to retort to the 192.168....blablabla
Actually, I did try that as well with the same results, but I can do it again and let you know in a coupla minutes
You do own the 201.17.6.x addressing though right ?
Assuming your internal addressing for PCs was changed to 192.168.1.0/24 your config should look like
ip address 192.168.1.1 255.255.255.0
ip nat inside
ip address 126.96.36.199 255.255.255.0
ip nat outside
ip nat inside source list 101 interface eth1 overload
access-list 101 permit ip 192.168.1.0 0.0.0.255 any
