DHCP Relay not working on two VLANs - SFOS 17.1.3 MR-3

Dear All,

 

This morning I started the upgrade of a Sophos XG generation firewall. After the upgrade everything works properply (so it seems). Suddenly I got a call that one of our VLANs is not offering IP-addresses to our clients.

We have the following set-up:

- VLAN-20

- VLAN-50

both are configured to use DHCP-relay. However only one is working properly, which is VLAN-50. Our other VLAN-20 is not working properly with the DHCP-relaying enabled. We've tested several things and one thing is clear: DHCP-requests and offers are processed through our Windows DHCP-server but there is no ACK coming from the Sophos XG. Therefore we disabled the DHCP-relay and enabled the DHCP-server for VLAN-20, which is working just fine.

Now my questions are (since I do found multiple posts regarding the above):

1. Is DHCP-relaying only allowed on a single virtual interface and DHCP-relaying is only allowed on no more then one virtual interface on a Sophos XG firewall? So I can't have DHCP-relaying enabled on virtual interface 1.20 and 1.50?

2. Is this a known bug? I couldn't find anything regarding a possible bug.
