RDP 8.0.14 Mac - NAT

Hi,

I've got a firewall and behind several 2012 R2 (Physical and VMs).

The firewall has its public ip, and also a public subnet routed to him (same results with private networks on a lab).

Connecting with RDP from several Mac Yosemite to the server nat-ed behind the FW public ip is ok.

Connecting with RDP from the same Mac to another server nat-ed on the other public ip stay on "negotiating credential"

Changing which server is nat-ed give the same result. So it's not specific to a server.

I've tried with others services (telnet server for example) and it works perfectly. Just not working for RDP.

To make a test : 

Mac Yosemite RDP 8.0.14 : 192.168.1.16
Firewall Wan : 192.168.1.253
Firewall Lan : 192.168.200.253

Server 1 : 192.168.200.1
Server 2 : 192.168.200.2

Subnet 192.168.100.0/24 routed to 192.168.1.253

On the firewall (in my case Checkpoint S680) : 

Nat 192.168.1.253:3389 to 192.168.200.1

Nat 192.168.100.100:3389 to 192.168.200.2

You can connect to 192.168.1.253 with RDP, on 192.168.100.100 stay stuck on "negotiating credentials"

Hi,

Is there any anti-virus installed on this server? or, have you set any firewall policy which block the connection?

From the error it seems that the credential is not accepted by RDP for the server. If it happens on single MAC device then suggest to install and reinstall the App and check whether there is any improvement. Also if you can find any useful log for further research.
