I have done a license server over a WAN before where we had a nice fat VPN between sites. Worked well. I now have to do one where i need to punch holes in the firewall. Has anyone done this? is it just opening port 27000 outbound from the XenApp Server and then 27000 inbound to the License server. Maybe a DNS entry so the XenApp server can resolve the name. I have to deal with other people on this and I am trying to have all my ducks in a row from the start on this. any input from those of you who have done this before is appreciated. Thanks! Greg
