I have my CentOS server at @172.16.17.100 and my remote network element at @172.16.17.110 and both ones have Internet access . I need to virtually put the remote network element on the same LAN as my CentOS server to be touched with . In my application , both the ip addresses are as invalid ones and I cannot change them . Can you please let me know if there is a settings on the CentOS server that can do the job or just the port forwarding on the attached gateway can be used ?
