Hi Guys,

I have 4 Server cluster i am trying to apply firewall rule to block 1 IP range from another interacting or accessing but i am unable to do so, i have been scratching my head since morning if someone can enlighten me a bit it would be great. firewall is enabled on Datacanter->Node-> VM also but still unable to make the rule implement on the VM. pve-firewall status also shows running.

Currently using the Latest Proxmox 7.2-7 Version with Bridge Network dhcp is managed by switch.

Trying to Block 10.250.0.3(vm-ip) Subnet from accessing 10.250.50.0/23 (mgmt-ip) which include blocking of Proxmox GUI also.

Attached is the Fw rule along with cluster fw config.

Code:
[OPTIONS]

enable: 1

[IPSET dns]

10.250.0.2

[IPSET mgmt-ip] # 0.x Segment

10.250.0.0/23 # 0 Segmentation(mgmt)

[IPSET nfs-ip]

10.250.2.10

[IPSET vm-ip] # 50.x Segment

10.250.50.0/23 # 50.x Segment IP (VMs)

[IPSET vpn-ip] # VPN segment

10.250.1.0/24

[RULES]

IN ACCEPT -source +vpn-ip -p tcp -dport 22,8006 -log nolog
IN DROP -source +vm-ip -dest +mgmt-ip -log nolog # disable play seg to mgmt seg
