The address 10.10.40.20 is not listening to the right port udp of the citrix (1604)
,but i need the IP-HELPER to this address because its my W2K-DOMAIN-CONTROLLER and the Vlan where the citrix server are need the domain controller for other services.
the problem is that the domain controller (10.10.40.20) answers to the
UDP-PORT-1604-BROADCAST of the citrix farm with ICMP-PORT-UNRECHABLE and its JAMMING all the citrix farm.
if i put the IP-HELPER 10.10.255.255 it is working ok,the station that need to answer to the udp-1604 is answering, but i dont want to put this configuration,
ip prefer the directed IP-HELPER.
so i need a way to block those messeges from 10.10.40.20.
thank you for your time,
