Ok after a full day of messing, trying to seperate one of my Redlight reshare's from a peer, so my other clients dont receive it, I found a quick solution.
Simply edit the C:line you receive from the peer with Redlight on by moving the caid identity up to hop 4.
Obviously you wont be resharing any cards from hop4 anyway, so this way you get to keep that Redlight channel for your second box at home.
All you have to do is set no limits on your second or third receiver box at home and you will receive the Redlight channel on hop 5.
Ok its not a great solution, but it sure beat's going through all your F-lines and blocking them from receiving that one Redlight caid.
If there is a simpler way of doing it please inform me
Example this is your Peers C:Line
C: Redlight.no-ip.org 12000 Password no
This is what it will look like after you have edited it.
C: Redlight.no-ip.org 12000 Password no { 0:0:4, 0b02:0:4 }#
0:0:4 is the amount of reshare's your peer allowed you to have 0b02:0 is the redlight caid identity and the 4 on the end id the hop number your moving it upto.
By putting the 4 on the end, you move that redlight caid upto hop4 on your server, out of harm's way of your other clients.
Ok it's not a perfect solution but its the quickest and easiest method that I have found.
Im sure there is an easier Method, but I could'nt find a simpler solution after hours of reading post's.
