Citrix Xen Desktop Connection


I'm unable to launch Citrix XenDesktop from outside my network. It gives me protocol driver error when launched from store front. Has anyone seen this error message before?

P.S I do not have a netscaler gateway in between. Currently using my firewall for port forwarding.

Can you post the exact error code?
Is this a computer that is able to connect internally?

Does this laptop work internally with Xendesktop?

i think it is not so simple to connect to the desktop from internet without NetScaler.
Except you use public IP's within your LAN.
Storefront put the (internal) IP to the launch.ica file.
This file is downloaded by the Client and he try to connect to the client (IP).
With NetScaler-configurytion within your XenDesktop environment the NetScaler-IP is added to the launch.ica as gateway.
Without Netscaler mostly the client can't reach the VDI.

Possible some firewalls manipulate the launch.ica file and take the gateway-rule.

VPN is an option to connect the client without the NAT-Problem.

You can try to use "netstat -n" while the client try to connect. You should see the connection attempt within "SYN SEND" state.
