Allow external IP range and ports

Hi Bradley ,

Thank you for reaching out to the community, so the traffic here in the picture is WAN To LAN ? 

Hi Vivek,

Thank you for your response.

It is WAN to WAN. Should it be WAN to LAN?

Kind regards,

Bradley

I am trying to understand the traffic flow here, so it would be great if you can elaborate your network topology, what is the source and where is the source in the network topology, what is the destination and where is the destination in the network topology...

Hi Vivek,

Just for your information, I have a basic understanding of networks, but I will try my best. 

The source is an external server with an IP address of 185.110.180.xxx. This external IP needs to be accepted by Sophos. This then connects to a VOIP phone that we have. I believe this would be on our local area network. 

Does this help?

Thanks,

Bradley

May I know where is VOIP server hosted exactly ? on prim or on Cloud ?

on cloud -LAN-WAN firewall is enough

So have you created a zone for your local area network ? if yes then behind which zone it is deployed to ?

Hi Bharat,

It is located on the cloud. IP address range of 185:110.190.xxx

Thanks,

Bradley

Then the traffic would be simply from the local area network to cloud, so a LAN to WAN rule should help...

Create a test firewall rule from LAN to WAN and keep on TOP with any service and check voice phone works or not
