Basic Config help needed 1841 Router 2 ethernet

Feb 15, 2007 2 Replies

Hi, I am attempting to configure an 1841 with 2 Ethernet connections and am unable to get things working with a simple config.


My setup is :


External IP Ethernet 0 - Internal IP Ethernet 1 NAT 10.0.0.X/24


Below is the config can someone notice any mistakes?.


I'm trying to replace an Belkin router with the 1841


Any help would be appreciated


thanks.

Config is fine, no problems with it.

What type of device is the outside interface patching in to? If a cable modem you would need to power it off for about 2 minutes to clear it's MAC table, most only allow a single MAC and the Belkins may be cached in there.

What does a show interface say? Are they both up and up?

From the router itself can you ping your default gateway?

Hi thanks for the reply.

Its and ADSL modem so at the mo there is an ADSL modem device with external IP address- Ethernet - Belikin ethernet router with external IP (this works fine)

yes both interfaces were up and up, couldnt ping default gateway.
