Caching dns

[Spearball]

I just setup a caching dns on linux with bind. Simply put my isp main dns servers in the forward zone on my bind dns which i configured through webmin. I entered my dns on my other computer and it worked perfectly browsing the internet. But.. when i tried to connect to world of warcraft i got connection failed. Also i can't use https connections anymore they just dont load.

Can anyone please help me :confused:

Thanks
