cccam server setup help + no-ip setup

Ok, if i got one share from a friend1 (c-line), and want to share my local card to friend2 (F-Line) not re-sharing friend1`s card

In my cccam.cfg

c: friend1.Cline port-number user pass
f: my.ip.dns user pass 0 0 0 { 0:0:1 } #will this setup make me only share my local card or cards??#

And friend2 Cline
C: my.ip.dns port-number user pass #or must it also have 0 0 0 { 0:0:1 } ?

And if i create a free no-ip host from my out-ip
How do i setup this? just make host name blablabla.ddns.net and put that in the Cline instead of my ip?
if the ports are open and tested, why cant my friend connect?

Thanks for fast answer.
I see i typed wrong, i had F: user pass 0 0 0 { 0:0:1 } and it was my friend that have typed wrong ip, working ok now :)
Is my F-line ok and secure? and how many shares can on card have?
If my friend wants to re-share it to his sat-tuner number 2, whats best? that i make a new f-line for tuner 2 or he makes a F-line?
if so, what will friends F-line look like?

The amount of shares a card can handle depends on the sharing emulator, the hardware used and the card itself. How many shares were you looking to add and what is your setup ? Are you using a sat receiver or linux pc server ?

Setup is DM8000 but i have a vu+ duo2 that maybe is better to use as server?
Using Cccam 2.3.0 cards are 090f and 0b00
I dont know how many shares, but lets say total 10-15 or will it be too much ecm time or not good for server.

Allow him reshare on the F line, then he can setup his own internal share.

Ok i just change my Fline from 0 0 0 { 0:0:1 } to 0 0 0 { 0:0:2 } and he can re-share it one time.
My cccam.cfg is totally clean, no code, only c-lines and f-lines. is that bad, or should there be some code from the original cfg?

Hmm if my friend has a cline form another friend, and he only wants to reshare my cline to other box2 how will that F: code look like?

Difficult but fun to learn this hobby :)
