WDM doesn't get SE 3125 Client

WDM doesn't get SE 3125 Client

Hi to the group

I've installed WDM 4.9.1.

All is working as expected for S30 client.

I've issues with old SE3125 client (around 70 client installed).
WDM is installed as Workgroup and only FTP is allowed.
Adds-on Rapport is trying to use HTTP port 80 Under FTP and so ... WDM doesn't get these client.
DHCP is set up for clients and port. But it only takes the Server address

Do you know if I missed :
- configuration to explain to Adds-on rapport to use the right FTP port ?
- the right rapport/WDM client to use on CE 4.1/CE 4.2 ?

Thanks in advance for any answer or tips ord advices ...

Best regards

Christophe
