881 router does not receive IP address from modem

Unanswered Question
Mar 16th, 2009


I'm having some problems with my CISCO881W-GN-E-K9 router.

The router is connected to a cable modem that has a dynamic IP address.

I have used the "Cisco CP Express" and "Cisco Configuration Professional" tools to setup the basic configuration (see attachment).

However, using this configuration the router DOES NOT obtain an IP address from the modem after restarting the router.

If I remove the WAN interface from the out-zone and disable/enable the fastethernet4 interface then an IP address is obtained.

I can then add the WAN interface back to the out-zone and everything seems to work fine.

This is off-course not the way it is supposed to work and I sincerely appreciate all input that will help resolve this problem.



I have this problem too.
