Hi:

Three weeks ago I installed an upgrade to my IPFire firewall.  This runs on a dedicated Linux computer.  It turns out that my IPS system "Guardian" is not compatible with the upgrade. I have spent two weeks trying to correct the problem, without success. Two days ago I build another FTP server and have been using that in addition to the old one. 

Tomorrow I am installing a new commercial firewall/router Asus AC-3100 at a cost of $300.00.  When I am finished I will have a new FTP server and a backup server.  I am doing the best I can to correct the problem and to make it much less likely that it will occur again.

Regards,

John
