Unable to setup Relayd virtual server

[ehaxhi1]

Hello,

I have 2 pi-hole servers I want to setup for load-balancing from my local network, I want to setup a virtual IP listening on the same subnet as my pi-hole servers which
clients can use to query both pi-hole server via round robin.

I am having a issue with the relayd plugin not working via the GUI, when I try to configure a Virtual Server with the following parameters, it will not allow me to save.
I don't get any errors, clicking on the save button does nothing.

Name: pi-hole-dns
Enable: checked
Server Type: Redirection
Listen Address: IP in the same subnet as pi-hole servers
Listen IP Protocol: UDP
Listen Port: 53
Interface: Pi-hole servers vlan
Transport Type: Forward
Table: Pi-hole-DNS servers
Port: 53
Scheduler: Round-Robin
Table Check: ICMP

If i change the Server type to Relay I can save the settings and I can see the virtual server configured but its not working, when i try to do a manual nslookup via "nslookup google.com <Virtual Server IP> i get nothing.

I am running the latest version of OPNsense  OPNsense 23.7.7_3-amd64.

Thank You
