Cisco 831 with Road Runner

[TiziteLayinLow]

I recently bought the cisco 831 router deisgned for broadband. It has a GUI configuration tool which is handy because im not really good on remembering the commands in CLI. Anyways, it has 1 WAN port and the theres 2 interfaces for it; Eth0, Eth1.. for NAT i have Eth0 set to the LAN IP and it uses DHCP to assign the 10.10.10.0 network to the workstations. Eth1 is the WAN which gets the IP from road runners dhcp.. with the road runner modem plugged directly to my workstation it gets online and gets the DHCP settings perfectly.. on the router it doesnt..

any ideas guys? thanks in advance.

does anyone have a normal configuration for a road runner connection on a cisco router?

thanks

I think you are a little confused, THe Wan gets a DHCP IP for the wan only. The PC's will get a DHCP from the router , but you need to give the E0/0 and E0/1 an IP address, and set the DHCP scpoe in the router.

oh theres no doubt about being confusion.. my internet doesnt work through the router..lol

my Ethernet0 is LAN interface with NAT inside and DHCP on with the pool of 10.10.10.1 - 254 with exclusions on the .1 for the router.

My Ethernet1 is WAN interfce with NAT outside and DHCP client (trying to get IP/DNS settings from RR)


I thought I had this correct, but again I dont know how RR is as far as PPP or PPPoE or anything of the nature. Is there specific settings for RR to talk to the router?

How can I use the CLI to get the WAN IP address? Everytime I use "Show Protocols" it gives me the interface but simply says the "Internet address is from DHCP" which doesn't really help the details. If I could figure that out, atleast I would know if the ACL has a problem or not.

Thanks for your reply, it is greatly appreciated.

EDIT: sorry guys im a total idiot.. i had to power cycle the cable modem to refresh the MAC address it was "married" to.. anyways.. the same config worked.. so thanks again. later.

ok thanks.. i found out i just had to power cycle..

BUT since you seem to know what your doing.. im wanting to fix my acl so that i can use either telnet or ssh, preferably ssh, from a remote location with the WAN interface.

i have a linux box for apache and i would like to login the router, then telnet from there into my linux box to check things and modify things.

thanks again, matt enderle
