Hi,
I am trying to configure my Cisco 1811 to work with a BellSouth/ATT DSL connection. My FE1 port is connected to ATT’s DSL modem. The interface is up and I have defined a PPPoE connection over this interface.
Here are the issues that I am having:
1. In order to get the static IP, DNS and gateway information, I have connected the DSL router to my computer’s port and defined a PPPoE connection. I have noticed a few strange parameters:
a. The IP address is: 74.173.58.*** and the subnet mask is 255.255.255.255 . I am not sure if the subnet mask is valid, when I try to enter those parameters to FE1 parameters, it tells me that the subnet mask is invalid. I have changed the IP Address mode to IP negotiated and it works however I rather set the IP to be static. What should I do?
b. The gateway is the same as the IP address, does it make sense?
c. I do not have DNS server in my internal network (For now) so I rather use the ISP DNS servers directly. I have entered the DNS servers that appeared under my computer’s IPConfig /all list. Is that ok?
2. When trying to “Test the Connection” , I have selected the “Automatically determined by SDM option and started the test. The test fails when it gets to: “Checking Exit Interface” and I get the following error message: The specified hostname/IP address is not routed through the selected interface. / Specify a hostname/ip address routed through the selected interface or add a 'host specific/network specific/default' route through this interface and retest connection.
I could not find how to follow the recommendation and the only thing that was close was the Routing section. I do not know if it make sense but what I have tried to do is to define a default route (Prefix/Prefix Mask set to 0.0.0.0) and the forwarding is set to the IP Address/gateway. I have to restart interface FE1 however I keep getting this error message.
I have attached a copy of the config below. Can you please help?
THANK YOU, JOE
