in the Fritzbox the port 902 is foreworded and open -> to the ESXi Server 192.168.178.41.
If the ESXi 902 is the Heartbead port it send it to the Astaro 192.168.2.254 the astaro will NAT it to the vCenter 192.168.2.8 because its annother subnet.
vCenter traffic for port 443.and 902 will be NAT by the Astaro to the ESXi Server. The Problem is must I NAT some of the 902 Traffic to vSphere or need it only 902 to ESXi and ignore vCenter vor this port?
