we have a BM3.8 Server for C2S VPN-Services. The Certificate Server is located on a 2 node Cluster in the same Tree / OU.
After generating the Client Certificates we have got the foolowing situation:

a) Using the VPN Client on the internal network, we can download and use client certificates.
b) Using the VPN Client connect over the internet, we are not able to download a client certificate. After a verly long time (apprx. > 1 Minute) we got an error -748 at the Client.

Please help us.
