Hi there

 

I am getting the below error when trying to access an external DNS address eg..   www.xxxx.co.uk 

 

The site is running on IIS, and has a host header for the correct URL . I have tried enabling/disabling URL rewrite and pass host headers, and also tried no firewall profile but with no luck. I cant seem to figure out where im going wrong, any ideas?

 

Thanks

    It appears that in stead of using the registered name, an application is using the IP-address directly which is forbidden (status 403).

    Thanks for the reply

     

    I still dont quite get it tho?

     

    In IIS, I have bindings setup to service files.xxxx.co.uk on port 80 , and the setup in the WAF itself on the sophos looks to be ok (i think)

     

    Im simply just browsing from a browser to files.xxxx.co.uk  and I get the Forbidden you dont have permission to access / on this server. 

     

    Any ideas?

    Under virtual server > interface

    I have always used the interface I would be connecting to from the client. This normally being the one connected to the internet.

    Is internal the correct one?

    Thanks for the reply.

     

    I'm using it on AWS so it only displays an internal interface. Im not sure the firewall is actually aware of its external interface as AWS does networking abit differently if I understand correctly e.g. software defined
