Can I change the HTTP port number?

dns was (my router) but when I changed it to it worked a treat. I can't say that I understand why because my router uses google dns addresses as well. But who cares it's working now. Thanks again to both of you for your help. Without it I'd have wasted so much time and probably wouldn't have found a resolution. People like you make it so much easier for people like me.
Excellent! No problem, always happy to help.
