Morning all,
So I am fairly new to Sonicwall/Firewalls in general and have a client with Sonicwall TZ300
Recently after a change to a new WAN connection the company has noticed that some of it's Sharepoint (Office 365) sites are not loading, they come up with just a blank screen instead of the usual content. No errors or blocking messages
I have messed around with the packet monitor and noticed that each time they try to load the site, the following is logged:
the IP 2.21.75.217 is part of akamaitechnologies.com which is the content delivery network for a lot of MS stuff.
I have tried allow sharepoint.com / akamaitechnologies.com / 2.21.75.217 in the content filtering, but it has made no difference.
Can someone tell me where I need to look to let this traffic through?
