Router programming question.

I am still very new to this.

Why when I set up a very basic program can I ping the ethernet side but not the serial side? Program set up via the router first power up.

Thanks, Dan

Re: Router programming question.

Is the serial interface 'up'? If it is not up, it will not respont to a ping.

Re: Router programming question.

From where are you trying to ping? If you are on a workstation on the Ethernet it works to ping the Ethernet because the router Ethernet and the workstation are on the same subnet (I hope). The workstation will need a default gateway to ping anything off the local subnet (the serial port). Am I correct in the assumption that you are at a workstation on the Ethernet? If so, check the default gateway setting of the workstation. It should be the address of the Ethernet.
