ipset

Hi, currently one of my vlan is having IPv6 /48. I am currently assigning VM a /64 subnet and set that subnet to the IPset field. But when I add another IP outside that /64 (but within the same /48) to the guest os. It's still able to use that and I could ssh into the VM. Is it possible to fix...

Hello, I am not sure if I hit a bug so I try to check it before submitting the bug. I created firewall for VM and the outgoing filter in iptables looks like this: Chain tap101i1-OUT (1 references) pkts bytes target prot opt in out source destination 0...

I have two Proxmox servers hosted at OVH. One is running version 5.4, the other 6.0. I've created the "management" IP set for my IP address on both servers. On 6.0 I can access the system. On 5.4 I lose access when enabling the firewall. So is the management IP set a new feature of version 6?

Hi all, I came by some weird behaviour i don't understand and I would like some help. I have a cluster (5.2) and I have a VM on a node. I am trying to prevent the VM of changing its IP. I have configured the "ipfilter-net0" ipset and as far as i understand this corresponds to the following rule...

Hello, I did a small research relatively ipset filtering for LXC containers and it turns out that using a standard ipfilter-net* set matching IP/interfaces doesn't filter external IPv4 traffic very well, when it is going out from an IP not defined in set. For example we can create interface...

Can someone please shed some light on ipfiltering. My understanding is that if we turn on ipfiltering in the firewall options we need to add the VM IP address so that traffic is only allowed to/from that ip. Is this correct? One thing we need clarification on is how is this setup? We read the...
