Sorry about not replying last nite -- I ran out of time and had to take my grandchildren "trick or treatin'" -- but I appreciate all the input. First -- I am not running an access list. I just got this router (2511) and wanted to configure it, including upgrading the IOS (existing IOS 10.2(4)). Thus, I first wanted to copy the flash to the tftp server. Apparently, this is where I have gone wrong!! With my advanced age as an "excuse" -- from hyperterminal I merely typed in "copy flash tftp" and was unsucessful: TermServer>enable Password: TermServer#copy flash tftp System flash directory: File Length Name/status 1 4404136 ij10240 [4404200 bytes used, 12373016 available, 16777216 total] Address or name of remote host [GREG]? Source file name? ij10240 Destination file name [ij10240]? Verifying checksum for 'ij10240' (file # 1)... OK Copy 'ij10240' from Flash to server as 'ij10240'? [yes/no]y ..... Copy aborted - TFTP timeout TermServer# This procedure has worked flawlessly for the past couple of years. The sole difference in my network now is that I have installed a Linksys cable modem and hub (100). That being said -- I wonder if Priscilla's last theory might be the culprit. My cable-modem router runs NAT. SO I'll do some exploring and investigating and get back to all of you later today. ' Thanks again for the assistance. I know my question (at least at my level of training) may seem dumb, but as a professor I used to tell my students, "The only dumb question is the one that is NOT asked!!!" So be patient and forgive me for my apparent lack of ability to resolve this issue myself!
