I have a 1924-EN switch connected to the 827 router. My network can access the internet just fine. My webserver (which is on the 1900 series switch) can access the net, but the outside cannout access hosted sites. The webserver is statically assigned 192.168.1.3....where am I going wrong
through reading the forums, I'm assuming the issue is within the access-list. I can add an extended access-list ( ip nat inside source static tcp 192.168.1.1 80 63.162.201.1 80 extendable) the command is accepted but still cannot access the site from the outside.
I appreciate the help

Should be:
ip nat inside source static tcp 192.168.1.3 80 63.162.201.1 80 extendable

The way you have listed would extend the router to the internet .1 instead of the server .3

By the way if you have extra ip routeable addresses in your ip block you might consider extending the web server using one of them instaed of your router outside address.

Looks like router reset on you and has some sort of problem with the flash file system. Does it come back to the same prompt after you power cycle the router?

That is strange.....booting into rommon mood either indicates a problem with the IOS image or the flash itself. Were there any other problems like caused by a power failure..microwave clock blinking...clock radios off...etc...

Just noticed something else. You need to extend your server to the outside address of your router and not the ISP gateway. Do you have additional IP routeable addresses available? If so then you way want to map one of them as to still allow ip http access to the outside interface of your router.
Also with DHCP running I do not see and exclude for the router ethernet interface.
ip dhcp excluded-address 192.168.1.1

Nope, no power outages or anything like that. The router was perfomring fine until I added that string to the running-config. that's when I lost telnet access. Got home and noticed the entire config was erased, I think the IOS has to be installed. As you see, I am a complete newbie to the Cisco world. I am CCO registered but don't have permission to access IOS dwonloads. I am stuck at this point.

I was thinking about adding a second static IP to my account
(guess it wasn't a bad idea) As for IOS upgrades, how can obtain the current IOS software for the C827?

How much ram and flash memory does your router have and is an 827 or 827h?

Also
you said "You need to extend your server to the outside address of your router and not the ISP gateway. Do you have additional IP routeable addresses available? If so then you way want to map one of them as to still allow ip http access to the outside interface of your router"
I am lost as to what you mean (NEWBIE ALERT) please explain further.

I really appreciate your attention to my issue, it is appreciated, greatly !!

Well early on you list the following:
ip nat inside source static tcp 192.168.1.1 80 63.162.201.1 80 extendable)
Then I list that if your server was 192.168.1.3 then it needed to be:
ip nat inside source static tcp 192.168.1.3 80 63.162.201.1 80 extendable)
However I did not notice that you listed your ISP gateway as were it would be extended...should have been:
ip nat inside source static tcp 192.168.1.3 80 63.162.201.72 80 extendable)
What this does is put your server port 80 accessable to http access by enterying 63.162.201.72 in the web browser of a remote machine.

On its way...hope it works out for you...
