Hi,
It's the first time i'm connecting my router to a Rogers Internet High speed (DOCSIS technologie) and i'm not getting any Internet..
Here is my config:
!
interface FastEthernet0
description Rogers
ip address dhcp
ip nat outside
ip virtual-reassembly
duplex auto
speed auto
!
interface Vlan1
ip address 10.x.x.97 255.255.255.192
ip nat inside
ip virtual-reassembly
ip route 0.0.0.0 0.0.0.0 F0
!
access-list 1 permit 10.x.x.64 0.0.0.63
!
ip nat inside source route-map NAT_Rogers interface FastEthernet0 overload
route-map NAT_Rogers permit 10
match ip address 1
match interface FastEthernet0
!
the thing is that i m getting a public ip adress from the provider but nobody can ping it and i m not able to go through internet and my VPNs are not working either.
Im running a (C181X-ADVIPSERVICESK9-M), Version 12.4(24)T.
I already checked with their technical support and the connection is fine if i put another router a dlink or a linksys the Internet is working just fine.
Thanks

What is the purpose of the 'match interface fastethernet0' in your route-map?

that is my way to say that i m nating my permitted traffic on access-list 1 with the ISP in FastEthernet0.
all i want is an exemple to how to set a Rogers Internet high speed in Ontario.
someone says to me that i should replace my default route :
ip route 0.0.0.0 0.0.0.0 f0 with ip route 0.0.0.0 0.0.0.0 x.x.x.x
where x.x.x.x is the default gateway from Rogers.

Remove that match statement. It is not needed.
The problem is you are telling it to NAT the address that is assigned to the FastEthernet0 interface as well, which is probably causing a loop.

i did remove it but no change..
i'm getting an ip address from Rogers but i can t go to Internet with that. do you have any exemple for configuring a cisco 1811 with Rogers wich is working please ?

Can you ping the gateway the cable modem gives you? Also, you did reboot the modem so that the router is associated to the modem right?
I have a similar setup:
interface FastEthernet4
description $FW_OUTSIDE$
ip address dhcp
ip nat outside
ip virtual-reassembly
duplex auto
speed auto
no cdp enable
end
interface Vlan10
description $FW_INSIDE$
ip address 192.168.1.1 255.255.255.0
ip nat inside
ip virtual-reassembly
end
ip route 0.0.0.0 0.0.0.0 fa4
ip nat inside source list 1 interface FastEthernet4 overload
access-list 1 permit 192.168.1.0 0.0.0.255

Remove that match statement. It is not needed.
The problem is you are telling it to NAT the address that is assigned to the FastEthernet0 interface as well, which is probably causing a loop.
It is not creating a loop. The 2 match statements in the route-map are specifying to only NAT when the source and destination are valid. The first match is the source (the ACL) and the destination is the interface as it has the 'ip nat outside' command.
If the interface goes physically down, then the route-map becomes invalid and no NAT will occur.
We need to see the routing table and nat translation from this router as well as the result from pinging from the router to the internet - say: ping 4.2.2.1
