I am grateful for your reply. What I did eventually after trying everything I could think of was to reload the configuration to an apparently safe previous state but to no avail. Finally I reloaded the 2.4.4.1 distro and rebuilt to where I was when the calamity made its appearance and all was well. Once in the clear I clicked for the 2.4.4.2 and that loaded beautifully.
You will be right I am sure but I just could not find it. As a noob I am a great deal clumsy and inattentive but I now have a working installation with OVPN server and clients, pfBlockerNG and Snort. I await delivery of my SG1100. What I am running on is an old AMD Athlon 2core with hardware crypto acceleration. I don't think that is working yet on the SG1100.
