You can not do that, otherwise the client will not know which RRC to connect to.
1) You must make the second set unique, e.g. 13011, 130012 and 130013, 13003, 13004, 13005 or similar.
2) This must be in both the server and client RRC's. Use a second profile in the control RRC for the second RRC
and its port numbers.
3) This second set of port numbers must be forwarded in the router to the second radio RRC's internal IP address.
