oscam proxy not working

hi!
I own and pay for a subscription. However I use a DM520 to share because I have 3 TVs in my house.
I decided to try to put a proxy server between my main Dreambox and the the three other boxes:

DM520 --> proxy_server --> client_boxes

The DM520 reads the smartcard
The proxy server connects to the dreambox through cs378x on port 12005
The proxy server then allows the clients to connect via cccam on port 1122

results:
- The DM520 works with no problems
- when connecting directly via cccam to the DM520 , the clients work with no problem
- when connecting through the proxy with cccam protocol, none of the clients work.

logs:
- the proxy is shown as connected
- the clients are shown as connected

- but no log entries on either DM520 nor proxy server that shows client request. No activity on DM520 log and the proxy-server only add this single line:

2021/08/05 18:22:20 3D565865 c   (client) encrypted cccam-client 10.5.0.10 granted (user001, au=off)

you will find my DM520 (DM520.conf) and proxy-server (proxy.conf) configurations in attachement.

Thank you all!

Ok for understand you DM are server box ?

Yes,
One DM520 is a server

It provides a cs578x share to a computer which shares it to the other boxes.
the other boxes does not work when connecting to that computer (which I call proxy) but work fine when connecting directly to the DM.

What might prevent the computer to respond to the boxes?

Ok use you DM for Share with cs378x Protocol and Clientbox with oscam or use on you computer linux with IPC server and share to you client with cs378x Protocol

DM SERVER OPEN CS378X > CLIENT USE OSCAM WITH CS378X PROTOCOL

my setup raspberry with IPC open cs357x Share to client box with oscam and cs357x protocol

No result, even logs are empty. I tried :
1/ DM with oscam <-- cccam --> computer with oscam<--cccam--> clients
2/ DM with oscam <-- cs378x -- > computer with oscam <--cccam --> clients
3/ DM with oscam <-- cccam --> computer with oscam <--newcamd--> clients

3/ DM with oscam <-- cs378x --> computer with oscam <--newcamd--> clients
Empty logs even at highest debug level. I wonder:

- is there any reason for oscam to not respond to client and show nothing in log?
- is there any alternative to oscam?
NOTE: if DM with oscam <------> clients

it works with not problem whatever protocol I use

found the issue!
After hours of debug and research, I found out that the value of IDENT needs to be specified (obfuscated on purpose here), do not leave it to the default 000000:

[newcamd]
#port = 12005@0100:000000 # <--- do not use the default 000000
port = 12005@0100:000XXX
key = 0102030405060708091011121314
keepalive = 1
mgclient = 1

NOTE: my final set up was:

DM520 newamd server <-- newcamd --> oscam proxy <--- newcamd ----> other clients with newcamd client
