WIC-4ESW configuration

Unanswered Question
Jul 12th, 2010


Please excuse my ignorance, but I had this card up and running a while ago and I swapped it out and put it in another router.  Now it is not functioning properly.  Basically my WIC-4ESW card is associated with VLAN1 which has an ip address of and the host router has an ip address of  I am trying to configure it so that devices plugged into the WIC-4ESW can access computers/servers on the network, which is plugged into the host router.  Any help is appreciated.

Attached is my config



I have this problem too.

Please update the show inventory command output, to see if there is any issue with the ESW hardware fault.

Under the VLAN interface, you have configured IP NAT (ip nat inside) but there is no corresponding NAT rules. Can you remove that statement and try to access from VLAN 1 to internal hosts?

Hi guys,

thanks for the reply.  After doing a little more research, I found that it was best to create a VLAN 2 and place all the switchports in that VLAN and leave the native VLAN blank.  The card is up and running now, but there seems to be one more drawback that I can not figure out.  Basically my test lab is laid out like this

wic-4esw(1751)--------simulated T1----------1760---------ethernet--------consumer router

From the command line on the 1751 I am able to ping outside address, like google.com and so forth, but computers pluged into the wic-4esw are unable to ping the consumer router (with NAT enabled)  which is, as well as the outside world.  I have attached my updated config
