Client can't find the server - more specific questions!

client
1

Hi there,

The following setting is given:

Server (Windows Server 2008 R2 running on VM), IP-Address 10.254.xxx, default firewall configuration
Client (Windows 7), IP-Address 10.10.xxx, currently firewall DEACTIVATED (for testing purposes)

The problem is, that the client can’t find the server in the local network.

When I walk through the manual, I understand the following sequence:

  1. Server sends broadcast message through network (sends from Port 35623 UDP)
  2. Client should receive this broadcast message (receives on Port 35622 UDP)
  3. Client should send it’s name back to the server (on which Port, and on which port the server receives it?)

The client log-level is set to debug and generates the following output:

I am not able to find a solution for this scenario. Any suggestions?
The webinterface is accessible via 55414 from the client machine.

Normally broadcasts do not cross sub-network boundaries. You could verify, if this is the reason by adding the client’s IP to “Add additional internet clients” (This causes a directed message to be sent for discovery).

If that doesn’t help, you could check via Wireshark, if the UDP packet gets sent/received correctly.

I added the client hostname to the “Extra clients” section and that worked perfectly!
All clients could be found by the server and backups are running!

Thanks!
