Hello everyone, I a newbie to this Cisco 1720, and was able to configure the Serial0, and FastEthernet0. My ISP gave me this block of IP address.

T1(WAN)
69.19.251.20 255.255.255.252 Subnet Address
69.19.251.21 LA Bridge
69.19.251.22 LA Bridge CPE Router (WAN)
69.19.251.23 255.255.255.252 Broadcast Address

Ethernet (LAN)
69.19.251.96 255.255.255.240 Subnet Address
69.19.251.97 LA Bridge CPE Router (LAN)
69.19.251.98 – 69.15.251.110 LA Bridge Customer LAN
69.19.251.111 255.255.255.240 Broadcast Address

I was able to ping from IOS, and from any computer to this ip address: 69.19.251.97, and 69.19.251.21, but wasn't able to ping from cisco IOS Hyperterminal to any website. Can you guy check to see if my configuration is correct?
thanks

Try connecting to the net from a device behind the router using your allocated IP range. I can ping your router.
