Greeting everyone. I have been struggling with getting an IOS image to ASA. I really need help to identify what I don't understand to remove forward. So far, I'm using a Solarwinds tftp server with the IOS in the C:\TFTP-ROOT file with Server Binding all correct. I have configure port gig0/1 on the ASA with 172.18.82.75 turned on and PC static IP as 172.18.82.10. I have enabled inbound under PC firewall settings and turn it off. I set up access-list 100 extended permit icmp any any echo and echo-reply for pinging and an access-list for permit of tftp, but the ASA and PC cannot communicate with a ping. I defaulted the config to remove issue to get upload to work.
I really need help with understanding the process for image upload on an ASA. If it can communicate, I can handle the rest.
Thank for the help!

We are not sure about your config how it was configured and what went wrong, you need to look at the global config :
look at below document TFTP section : hope that help you :

hi,
is this a direct cable connection from ASA to your PC?
you just need to configure a layer 3 IP on an interface and do TFTP.
you can alternatively use the USB or ASDM to upload/upgrade the ASA image.

Hi John,
Yes, I have my PC directly connected to ASA on gig0/1. I have tried a usb, but the file does not show on the usb. I formated to FAT which should be the correct one, placed IOS on it, put it into the asa with disk1: showing, and file does not show up, then I tried a reboot but same result. Not sure if we have ASDM for use, but I see as I'm new to this company.
I have the config in the reply above if you like to look.
Regards
