I am using microsoft xp and have recently upgraded to Norton 2011. Prior to this I was using 2010 and connecting two Linux satellite receivers using a dyndns server. Since using Norton 2011 I have been unable to connect them. I have my router set to open the required port and everything looks ok but when I do a test it shows that only my extenal ip address is showing the port is open and not my dyndns hostname.
Do I need to open the port on Norton and if so how do you do this? or do I lower the the security of the firewall and again how do I do it?
Any help would be greatly appreciated.
