So all of sudden my firewall started blocking the webpages of tumbler blogs. I can still acess tumbler and my dashborde, but if I try and open the blog webpage it says internet acess is blocked.

I checked by turning my firewall off that I can acess the site then. 

Is there a way to add all tumbler affliated sites. I tried adding the IP to my network conections, but it did't work.

Coudl you please show me as a step by step guide.
