I just received my replacment ASA5550 firewalls from Cisco and they onlt have an IOS loaded on  DISK0:  (723-K8.bin)

I want to load the latest IOS (8.22-K8) and ASDM (asdm-631.bin) on DISK0:

I configured the port GI0/2 with an IP (

I am using TFTPD32 also solarwinds TFTP app. on my laptop (

I try to ping the x.x.4.51 from the firewall and do not get a response, I get a response from 4.1 (the FW Port)

From the laptop I can ping the FW.

Where am I going wrong in the firewall setup?

I added the lines

tftp-server "gi0/2 name" asdm-631.bin

the interface gi0/2 is up / up and Security level is 100

Can you please post the output of 'show run interface'? You should have something like this:

int g0/2

   nameif inside

   security-level 100

   ip address

   no shut

Also, double check your server to make sure there is no host-based firewall enabled that would block this traffic.

Hope that helps.

Did you check your server configuration to make sure there is no host-based firewall configured there? Can you ping the server from the ASA? Does the 'show arp' output on the ASA show the correct MAC address for the server after you try to ping it?

No firewall on the Laptop. and I can't Ping the Server from the ASA.

Forget it, I used the External Flash card to install the files

, then set the BOOT to Boot System disk0:/asa822-k8.bin

and set the ASDM to asdm image disk0:/asdm-631.bin

and all works now. I am not sure why I could not ping the TFTP Server from inside the firewall but I could from outside.
