Thanks to both once again! top notch support and kindness!
Tonight when I get home I'll try Colin's approach to avoid any of the issues he stated (I'm using CTF + FA if it counts).
Just to win some time: if it works I do have to add it to wan-start script to make it permanent, don't I?
And to undone changes just delete that line from script and reboot, right?
Will report back with results!
Yes, you will need a wan-event script. I have an example that Colin wrote that I can post on Sunday if you need help. Won't be near a computer till then.
