Dear Sirs



I have an Cisco 837 where the CRWS-interface goes into an infinite loop when trying to configure the 837 to my ISP. They have recently removed login with username/password, so I tried to let the 837 via the CRWS-interface findout the config parameters via Quick-setup, then the infinite loop starts. If I monitor the 837 through consol, I can se that it starts with someting. sh ver for my 837:

As the CRWS-interface went into an loop and as I am not so familiar with Cisco-router setup, I would be wery grateful if somebody would take some of their time to help me with this task, I have seen some configs in this group, but they all applies to username/password login to ISP.

Your NAT acl is messed up, your only allowing deices with X.X.X.1 addresses to be nated (which in your subnet is only your ethernets interface).

conf t no access-list 1 permit 0.0.0.1 255.255.255.0 access-list 1 permit 192.168.0.0 0.0.0.255 exit wr mem

Hello I have now an config like this:

when executing sh arp, it gives this:

It indicates some connection to the outside.

Where am I wrong in the configuration?
