since we don't know how the license server works it's not really possible for this problem to be solved. does the client send a request first? or does the server just "hand out" licenses? does the server use broadcast to send out the replies or does it reply directly to the IP of the client? if it does indeed just broadcast then you're stuck either moving the machine or adding a NIC to it or rearranging your VLAN or some such.
My only hope was if someone knew how Opnet license service works. Having said that, I ran wireshark on client and checked what the application is doing and saw that there were attempts to connect to port 2047 (udp) on server IP but it seems when Lic. server checks the client IP and finds that not being in the same network, rejects it. The application has a configuration to provide IP of lic. server.Thanks again
