Cisco Vlan and IP helper

Group, I've just implemented VLAN's enterprise wide. All is well
*EXCEPT* our citrix clients are not finding application sets.

Example, I have Vlan20
with two ip helper addresses:

10.1.20.102 <- our dhcs server
10.1.20.181 <- a server from our Citrix farm

From Global, I've also added a protocol forward for 1609 UDP....

I still am not able to connect to our citrix published applications.

If I go into the Citrix Client, and manually add "10.1.20.181" under
service addresses, all works well. I don't want to have to do
this on all workstations.

I have removed all ACLs with no luck.

Anyone have any advice?
