Kia ora all

I am embarrassed to admit it but I have totally failed to set up our new household with workable internet.

I am not very skilled however never had a problem like this. We changed house, and provider, and got a new router. So we are naked Vodafone ADSL 2 with flash looking SHG1500 . The old router was given as a gift to a colleague of my wife (and now I wish it wasn't...)

I searched all around the net and cannot find a complete manual or advise what to do when your internet seems to be working fine but ports are blocked and open port check cannot see them. I had set up port forwarding, as on my old modem, but nothing works. Friend told me it may be firewall, so I lowered setting to 'low' however nothing happened either. There are so many settings under 'firewall' and I am not quite sure whether I should just start playing with them (and I do not understand what they may mean..). Also under 'user permissions' setting all is 'on' but 'sharing' - shall I turn it on? I found only very very basic vodafone manual that does not explain each setting. Skype is not working properly, p2p is not working at all, basically it seems like there is something 'blocking' us. The ports are set and on though...

 

Can anyone please, please help us?
Many thanks, and happy Easter!
