Can I use another port for the proxy server Note : The license files for the proxy are in folder  /opt/flexlm/bin . There are two license files:  atflexd-proxy.lic  and  proxy.lic . Via these license files the license server process  lmgrd  starts two vendor daemons: atflexd  for the T2K licenses socbu  for the 93k licenses If the customer wants to use another port for the  lmgrd  process of the proxy server or another port for the  socbu  /  atflexd vendor daemon, then the files in folder  /opt/flexlm/bin atflexd-proxy.lic proxy.lic need to be adapted with the appropriate port number on the SERVER line(s) for the lmgrd process and on the VENDOR line for the appropriate vendor daemon process on all used proxy license servers. So if the setup is an FNX triad, the port numbers need to be adapted on all three license servers. Please always adapt both license files. The license server will run into errors, if you use for example different port numbers for the  lmgrd  process in file  proxy.lic  than in  atflexd-proxy.lic .
