Add IPs to default listener on 11.2.0.3 RAC (no VIPs)

Hello,

      I'm trying to find info about how to add an IP to the RAC listener. Today the listener looks like this:

Listening Endpoints Summary...

  (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=LISTENER)))

  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=10.200.120.68)(PORT=1521)))

  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=10.200.120.66)(PORT=1521)))

Which are the VIP and PUBLIC IPs on one of the nodes.

Because I'm connecting to the nodes through VPN to the  management IPs, and this IPs are the only ones available through VPN, i want to add the management IPs to the listener so it will look like this:

Listening Endpoints Summary...

  (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=LISTENER)))
