Cisco 827 Router Config

[Linc1]

Hello,

I just switched out my router for a Cisco 827 ADSL Router and I am having an issue since I configured it. Basically from the public side everything works and I can see the web server and I can send and receive mail on the mail server. I can even access the webmail as required. But from the private side of the router I cannot access anything unless I use the private IP address of the machine I am trying to connect to. Can someone help me with this? What have I done wrong?

Below is the config

I could also use help with the one incorrect access-list as
I don't know how to remove it.

Thanks in advance.

But from the private side of the router I cannot access anything unless I use the private IP address of the machine I am trying to connect to. "

That... sounds pretty normal if I understand you correctly. Could you restate the problem?

As for the access list, you'll have to do it over - no access-list 1, then type it in again.

 

[Linc1]

So it is normal that to access web servers on the private side of the router I cannot use the

http://www address

I have to use the IP? When we use the

http://www address

what we get is a user name and password prompt from the router? This is all normal?

 

[plshlpme]

so are you saying that you are trying to access your internal website via the DNS name which is tied to your wan address?

that wont work im afraid...

you will need to house a private dns server for your internal hosts if you want that to work..
or edit the host table of the internal pcs if there aren't to many.

Before I switched to the Cisco unit, I was able to do this. I didn't have this issue. I guess Cisco isn't all it cracked up to be.

I FIGURED IT OUT! ! ! !

It was basically an accident, but it works now like it is supposed to. At least the way I believe it is supposed to.

contact me off list and I will supply my config and you can use it to work yours.
