There is the following problem: the version of my proxmox is 8.4.1, version of OPNsense is 25.1. The allocation of a DHCP address for VMs on linux bridges has stopped working. I have tried the following: 1) I completely reinstalled the hypervisor and completely reinstalled the firewall 2) The problem is not with the firewall I think, I tried versions that worked for me for a long time. 3) One time i saw the following error message in ISC-DHCP: dhcpd Error: 192.168.1.1: no subnet.
My configuration of Proxmox:
auto lo
iface lo inet loopback
auto enp1s0f1
iface enp1s0f1 inet manual
iface enp1s0f0 inet manual
iface enp90s0 inet manual
auto vmbr0
iface vmbr0 inet static
address 11.1.1.21/24
gateway 11.1.1.1
bridge-ports enp90s0
bridge-stp off
bridge-fd 0
#Used for WAN
auto vmbr1
iface vmbr1 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0
#OPNsense LAN
auto vmbr2
iface vmbr2 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
#OPNsense VLAN
I use VirtIO in Opensense as bridge interfaces.
I tried with basic config for OPNsense from installation.
Hello. Wow, loads to unwrap there.
Try again with sharing some configuration settings and a clearer explanation. I for one can't yet make head or tails from that paragraph.
Bridges without bridge-ports (or with a port that does not seem to exist) are not going to achieve much.
Did you swap networking hardware?
The proxmox IP on the WAN side wouldn't be my first choice. Also, did you obfuscate that range?
