Citrix Web Access = Webinterface/Storefront only
... or WI/SF with Citrixsecuregateway (CSG) or Netscaler Gateway or AccessGateway or VPN

do you use "Citrix Web Access" for internal and external access?
if yes how do you configure the external sites?

do you use external access before without problems?

Internal access no issue, external access via NS AGEE. FW rule change to allow traffic from NS to Citrix servers on port 1494 and 2598 allowed.
And in XA 6.5 there is no session reliability enabled.

do you use webinterface or storefront?
with webinterface. do you create a site for gateway-access?

use "netstat -n 5" at the client while trying to build the connection.
check for sessions with "syn_send"
which port use these sessions?
