Accessing a Citrix implementation over an Direct Access / Universal Access Gateway solution, in most implementations, will result in an error. DA/UAG is a IPv6 based technology. The ICA file rendering on the Web Interface uses IPv4 addresses. IPv6 cant talk directly to IPv4. But this can be done with IPv4/6 transition technology’s like ISATAP. That again will require the Web Interface to use a DNS names and not IPv4 addresses.
Here is a guide for a Citrix Secure Gateway & Web Interface implementation
If you are not using CSG, and if a Citrix client (receiver) connects over DA/UAG straight to the Citrix Web Interface underneath solution should work. (if you use the correct IPv4/6 transition technology)
1) Enable XML service to use DNS address resolution (Citrix Policy’s)
2) Edit the Citrix Web Interface webinterface.conf file
3) Change the: AddressResolutionType=IPv4-port
To the vallue: AddressResolutionType=DNS-port
4) Save and close the file and perform and IISReset
Will need some further testing on this,
Well that didn’t work…. But you might wan’t to try this:
receiver and webinterface. Something with additional communication to some components of Citrix.
