This can be done on a PC with any one of a few dozen utilities that are publicly available, my personal preference is one found in the very helpful toolset from Chesapeake, look at http://www.ccci.com/tools/tftpd/index.html Look over http://www.cisco.com/warp/public/779/smbiz/service/knowledge/general/tftp.ht m for the general instructions on how to download the new code to the router. This location also has pointers to a TFTP download utility as well as some alternatives, along with the Step by step intructions for the transfer and download of the code to the Flash on the router. Once the download is completed, check the size of the image on the flash with the original file. If the sizes are comparable, the new image should be set as the default boot image from EXEC mode. Something like (config)#boot system flash flash:2:filename 2) As to whether you should do it, this is very dependent on your circumstances. If the version you are running is stable and working well, check to make sure it is Y2k compliant and if there are any significant security considerations. If neither of these are an issue, then look over release notes for later versions and see if there are any features that are incorporated later that would be of benefit to you. All this is available on the Cisco site www.cisco.com. In a real world scenario, if you have access to the newer IOS code, and if you can spare the time and equipment downtime to figure out how to do the upgrade, it would probably be a worthwhile effort, and you probably would find features that would be nice to have. Olaf, As a general note, instead of firewalls, you may want to check out the Cisco Newsgroups specifically for more pertinent information regarding Cisco routers.
