Hello Everyone
For a big project I'm configuring its firewall and edge (in a test environment)
I'm not a experienced user in Sophos UTM Firewall 9.1 since I'm still trying to learn how the use and configure it.
What I am trying to do is to make my Edge Exchange 2013 (in DMZ) connect to my internal DNS server so I can setup mail filtering. I've tried different methods mentioned here on the forums or in the administrator guide. But I haven't figured it out yet how to exactly configured it.

In the picture above you see a part of our test environment. Here you can see the IP's assigned to each machine and how the network is in general.
What so far is configured on the firewall is
For the Internal Network to Gateway interface (firewall)
Static Routing
192.168.11 to 10.9.15.235
10.9.15.235 to 192.168.1.0
DNS Global and Forwarders
Firewall
NAT Masquerading
Intrusion Prevention
Web Protection
Antivirus
With these configurations all internal hosts, Workstation and Servers are able to connect to the internet. All traffic is routed between those interfaces
The Edge can't do anything yet since nothing has been configured for that interface
Both the firewall and the edge are installed on VMware Workstation
Sophos UTM 9.2
Edge Server(Windows Server 2012)
The Firewall has 4 network interfaces
1) From Firewall to ISP
2) From Firewall to Edge
3) From Firewall to Internal Network
4) from PC to Management interface (separate)
The Edge has 1 network interface
The Goal is to connect my Edge to my AD/DNS.
All interfaces can be pinged by the Edge machine that are on the firewall and the outside interface of the router.
But cannot ping the inside interface of the router itself or ping the internal AD/DNS.
The Router has NAT enabled.
Firewall is only there to filter and scan the packets and monitor the traffic.
Also, Is it better to configure NAT on the Firewall? if yes, How would I configure it to do so?
I would like to know how I can configure the DMZ so it can reach the internal AD/DNS. I couldn't find any step by step guides or videos about it. I would like to get some help to configure it from the beginning to the end, Which settings do I have to do and how do I do them? and what are best practices for this?
I would like to have any piece of information that can help me with this
if you miss any information to help me with this please ask and I will update this post with the additional information
Yours Sincerely
Anion
