Cannot TFTP to Cisco ASA

Post by Pulse69 » Mon Oct 21, 2024 1:30 am

In GNS3, I had no issues copying a file from a TFTP server to a Cisco ASA. In EVE-ng, I have tried using Cloud1 & VMnet2 for both the INSIDE interface and Management interface of the ASA. I am using the IP address on my Ethernet LAN adapter for the TFTP server. The TFTP server is listening on that address on port 69 as well as several other addresses and i have tried all of them. I can ping from cmd.exe to the ASA interface however I cannot ping from the ASA back in the other direction. I have enabled ICMP on the ASA...

Thank you for any assistance...

Ping from ASA to your native host will not work, until you will allow ICMP rules on your Windows FW. It is under Windows Defender Firewall/Advanced settings
you must allow inbound and outbound ICMP rules

ICMP has already been configured both inbound & outbound on the inside interface. There is no route to host
