VLAN Comunication

Hi,

I am new to Sophos XG. I have a few VLANs setup. (Please see the attached picture)

I have VLAN 3 for servers and then VLAN 5 is Trusted Wireless. I want to be able to talk and use remote desktop between VLAN 5 and 3 for server maintenance.

Would you be able to advise me on what firewall rules I need to make for this to work?

I also have an Active Directory DNS server sitting on the 3 VLAN. When I currently connect to the Trusted wireless VLAN (5) I am unable to connect to the DNS server 10.128.8.2 which is sitting on the Servers VLAN (3)

Any help would be much appreciated.

Kind Regards,

Charlie.

Hi Charlie Scarlett

Thank you for reaching out to the Community!

Please configure LAN to LAN rule with VLAN 3 and 5 networks in source and destination networks. Did you also configure static routes for VLANS to use the Port1 interface as a gateway?

Thanks,

@H Patel, Does this look correct?

Hi Charlie Scarlett

The firewall rule looks correct.

You only need to configure the static route on the XG if you did not configure it on your switch for the VLANs.

Hi Charlie Scarlett

In destination IP /Netmask you can add VLAN network and select interface as Port1.

bad practice, dont you lose half of the purpose of having VLANs by doing that?

He only needs to open 2 ports (DNS, RDP) between VLANs not the entire network.
