You can change the server name to 1.nfps.bz which should work unless you have DNS issues. If it does not work then you can enter the IP address as suggested by Vann, before you enter the IP address, first you will have to change the field from domain name to IP address.
Suash, I am using Ilink 9000 Plus and it is still not working. I have tried both 1.nfps.bz and IP Address 68.212.88.227 with 10810 and 10910 ports. Need help. Still down. Thanks.
