I was unaware of a “Remote Desktop App”, I have never used it, I always just use MSTSC to connect to my servers. But I wonder if when you start the app, if you need to do it as “Run as Administrator”?? Very odd problem.

I sure the trouble in Remote Desktop App. I use Shrew or Cisco VPN many years without troubles. This issue is the first one. I've sent message to developers. -- Best regards, Yury 2018-06-18 13:40 GMT+03:00 Seth Dunn <[email protected]<mailto:[email protected]>>: Couple things I would check since this is RDP, and you say that connecting to other things works fine… Windows Firewall on the target box The target box can accept RDP connection (Control Panel\System and Security\System\Remote Settings) If it can, then I would remove the check mark from the box for Allow only computers running NLA I assume you are able to ping the target box?

I am assuming this is the IP address of your LAN and I suspect is where your problem begins Yes, you are right. 192.168.71.3 it's LAN IP of my PC. 172.17.19.0/24<http://172.17.19.0/24> - it's VPN-subnet. I don't understand why traffic not going through VPN subnet when I use RemoteDesktop App, but does so in any other application including RDP-client. Thank you very much for your help. I've understood the problem in RemoteDesktopApp. -- Best regards, Yury 2018-06-18 2:19 GMT+03:00 Larry Moore <[email protected]<mailto:[email protected]>>: Hi Yury, On 17/06/2018 5:08 PM, Yury Kolos wrote: Thank you for your response Larry. It would seem your VPN tunnel is working just not the application. App not working only through ShrewVPN. I expect you will see some packets relating to connection establishment. If so, could your PIX be performing deep packet inspection and blocking the connection!? When I connectin RDP-client I see established connection in netstat utility: netstat -na | findstr 111.250 TCP 172.17.19.150:49942<http://172.17.19.150:49942> 192.168.111.250:3389<http://192.168.111.250:3389> ESTABLISHED But when I try to use Remote Desktop App I see only Syn_Sent in netstat: netstat -na | findstr 111.250 TCP 192.168.71.3:49929<http://192.168.71.3:49929> 192.168.111.250:3389<http://192.168.111.250:3389> SYN_SENT Note the source IP of 192.168.71.3 above. I am assuming this is the IP address of your LAN and I suspect is where your problem begins. Packet trace in attachment. Could you see? Looking at your packet capture I can see three RDP sessions going through the Shrew VPN, I am also assuming these connections were made after the above 'netstat' command was issued. I expect if you perform a packet capture at the gateway for the subnet 192.168.71.0/24<http://192.168.71.0/24> and you look for packets destined for host 192.168.111.250, you will see the SYN requests arrive. If so, you will need to determine why your Remote Desktop App is using your LAN's default Gateway instead of the routes set up by Shrew VPN.
