Configuring Sophos XG136 Firewall port for connecting switches.

EDP AFRO

We have 40 Srvers and we want all the users to connect the servers through XG-136. We have 40 Switches out of  which 4 are connected to servers. All of these switches which are connected to servers I want to connect them to North End of the Firewall and our L3 will be connected to south end of the Fitewall. Servers IP addresses are 157.61.3.0/24 whereas Switches have 157.61.10.0/24 as their Managemen IP.s. Users are devided into 4 VLANs. 157.61.2.0/24, 157.61.4.0/24, 157.61.5.0/24, 157.61.6.0/24 respectively 

Kindly advice how to configure Firewall ports for switches which are connected to servers.

    Hi ,

    Thank you for reaching out to Sophos Community.

    What are you referring to North End and south end of the firewall?

    It would be great if you can share a rough diagram of your network environment.

    You can configure a physical interface with 157.61.10.0/24 subnet and then configure routing on Sophos Firewall to connect to server network 157.61.3.0/24. Assuming this interface is kept in the DMZ zone.

    For users, you can configure VLAN interface(all are in LAN zone) on Sophos Firewall with required VLANs.

    Sophos Firewall: Configure Virtual LAN

    After that create a LAN to DMZ & DMZ to LAN firewall rules to allow communication between servers and users.

    Thanks sir, for your prompt reply. I have already configured VLAN on incoming connection from L3 switch. Shall I configure LAG on all the connections of L2 switches at Sophos with IP 157.61.10.0/24. Kindly advice.
