[44net] Amprnet Gateway Subnet change help

Hi, My current Amprnet Gateway subnet is 44.163.22.2/32. I will like to change the subnet to 44.163.22.0/24 to be able to access other IP behind the Gateway. I try to do it in Amprnet Portal but it have predefined subnet network and not been able to enter the subnet manually. I tried yesterday e-mail with my gmail account to gateways(a)ampr.org with commands to the robot but no response back. Until this morning with Gmail Warning "Technical details of temporary failure: The recipient server did not accept our requests to connect." Please anyone who have access to the Gateway Database can help me with the change. Thanks, 73s Jose / HP2AT
