Backup your config, if you don't have a backup already. Get the 7.3x ISO from the ftp.astaro.com, and re-install, and restore the backup. I'm not sure if 7.4 backups work in 7.3, but if you have a 7.3 backup, that would be best.
You can put an unencrypted back on a USB memory stick, and boot the firewall with the stick in the USB port, and it will import the configuration during boot.
I have automatic backups turned on, so I do have a 7.3 backup. I have a backup firewall connected with a crossover cable that keeps the backup up to date with the main firewall. When I restore the main firewall to the old version will it update the backup firewall or will I need to do that one as well?
