Resolution:

The error message means  the gateway is not allowing the program ID <program id> to be registered from the host <external host>

There are two possible reasons:

1. Parameter  "gw/acl_mode = 1" and not reginfo file has been set. This is the default value for NEW INSTALLATIONS for Netweaver  7.0x since December 2012 (including 7.20) and for  Netweaver 7.3X since August 2012
2. There is a reginfo file that doesn't allow the registration of that external program

Update the "reg_info" file from the SAP gateway that appears in the error message ("SAP-Gateway on host <hostname> / sapgw<nr>") creating a line that allows this registration.

The location of the "reg_info" file is specified by parameter "gw/reg_info" and should contain lines like:

 #VERSION=2
  P TP=<program ID> HOST=<external host> CANCEL=internal,<external host> ACCESS=* 
  ... 
 # the following lines should be the LAST lines in the reginfo
 #
 P TP=* HOST=<LIST> CANCEL=<LIST> ACCESS=<LIST>
 P TP=* HOST=local​

 Following recommendations from SAP Note 1408081 :  Basic settings for reg_info and sec_info

and settings  for ACCESS clausule from SAP Note 1592493 : GW: Problems during reginfo configuration
 

Then, reload the new settings via transaction SMGW

And try to register the program again.
