Hello guy, I've been struggle with this router. I don't seem to get it online at all. All i need is to be able to get it online. I've got this block of address from my ISP which is LABridge.com
I'm a newbie to this Cisco 1720, if you can guide me all the commands to get this box working, I really appreciate it. Thansk

Hi
this lines it's wrong
ip route 0.0.0.0 0.0.0.0 69.19.251.23
ip route 0.0.0.0 0.0.0.0 FastEthernet0
I think its enough
ip route 0.0.0.0 0.0.0.0 69.19.251.21

the second problem why are you use two routing protocols
RIP and IGRP leave only one. Its not mistake but in this configuration IGRP have prioritet.
 
If you have a frame-relay circuit on S0, then you'll probably need to configure it for the DLCI provided by the telco.

for example:
interface serial0
description T-1 internet connection
encapsulation frame-relay ietf
frame-relay interface-dlci 100
ip address 69.19.251.22 255.255.255.252
ip broadcast-address 69.19.251.23
ip nat outside

Hi

You will need to configure NAT too if you are trying to access the internet. Configure your Dialer

Try the following:
Dynamic NAT
(config)#ip local pool ourpool <start ip address of internal LAN> <end ip address of internal LAN
(config)#ip nat pool outsidepool <internet IP address> <internet ip address> netmask <ISP netmask>
(config)#ip nat inside source list 101 interface <external interface ie dialer1> overload

IP Route
ip route 0.0.0.0 0.0.0.0 <external interface>

If both RIP and IGRP are set on a router, the router will use IGRP over RIP

You should also encrypy your passwords ;)

Hope this helps



 
It still not working. Do i need special cable like RJ48 connect from the wall to the router?
 
mine is more of a question..
did the ISP asign both blocks of number?? if they did you do not need the NAT staments.

my 2 cents
 
yes, both block if IP address were assign by the ISP
