The port needs to be unique per resource, but the same for both peers.  
Here's an example of a known-working configuration used with Xen for 
live migration:

resource r<unique resource name>  {
   net {
     allow-two-primaries;
   }
   disk {
     on-io-error detach;
   }
   on xen01 {
     device      /dev/drbd<unique drbd device number>;
     disk        /dev/vg1/drbd.<guest name>.xvda;
     meta-disk   internal;
     address     10.0.0.1:<unique port number>;
   }
   on xen02 {
     device      /dev/drbd<same drbd device number as above>;
     disk        /dev/vg1/drbd.<guest name>.xvda;
     meta-disk   internal;
     address     10.0.0.2:<same port number as above>;
   }
}


That goes into /etc/drbd.conf on both nodes; I would edit on one and 
copy to the other node when finished to make sure they're in sync.
