As far as I can tell I have not set up any restrictions. I cannot connect to Youtube using an iPad; however, I can coonect to Youtube using a Windows based laptop via the exact same wireless connection. The iPad can connect to the Youtube on other wireless networks and if i connect the wireless router directly to the Internet port rather than via Wingate. The error I get 'Cannot connect to Youtube'. (it also happens on other video sites but I am not sure whether these sites are merely embedding Youtube anyway)
Can someone please give me a pointer in the right direction.
