I have just purchased a cisco 1720 with 3 ethernet ports - 1 + 2 insertable ethernet cards - it took a while to figure out that the IOS (12.1) that was installed on the router did not support the Wic-1enet that I purchased with the system - I found the problem/solution at this site - thanks - so I downloaded IOS 12.2(4t)and the cards now work =
Problem:
I have also purchased with the router the firewall feature pack - when I went to install the firewall it seems as though it is included with an older version of the IOS - 12.05 -
My concern is if I load the firewall my ethernet cards will no longer work with an older IOS- when I load the firewall will it overwrite the newer IOS - 12.2 - or is the firewall a module and not the IOS-12.05- with the firewall included?
I hope that this is a clear question -
This is my first experience with cisco and I was surprised to get a piece of hardware (router) and insertable ethernet cards (wic-1enet) and the software installed on the router did not support the ethernet cards purchased with it -and then the firewall appears to present the same problem -
Thanks for any help
