kvm+opnsense+Vlan problem - must manually reload firewall rules after reboot.

[dieterarn]

Hi, I'm having a bizarre problem with my setup:

I've got several VLANs segregating things. These are setup on my hypervisor (KVM/PROXMOX) as Linux bridges associated to specific VLANs.  i like making all the VLANs separate bridges because i can control what other virtual machines on the host can connect to.Obviously OPNSENSE is running as a virtual machine.

I had some weird problems: any thing that was connected to "base lan" worked ok straight after reboot but anything bridged via a configured VLAN wouldn't. through trail and error I discovered that if i touched a firewall rule and caused a rule reload everything would start to work. 

Has anyone here tried to setup VLANs and OPNSENSE in visualized environments? Is there a way to at least automate my workaround and cause a rule reload after everything is up and running?

i've reproduced the problem a half dozen more times. i've also tired running:

pfctl -F all -f /etc/pf.conf

to flush the firewall rules and reload but it errors out:

Code: [Select]

root@OPNsense:~ # pfctl -F all -f /etc/pf.conf
rules cleared
nat cleared
5 tables deleted.
140 states cleared
source tracking entries cleared
pf: statistics cleared
pf: interface flags reset
pfctl: /etc/pf.conf: No such file or directory
pfctl: cannot open the main config file!: No such file or directory
pfctl: Syntax error in config file: pf rules not loaded

i was going to add :
@reboot echo /sbin/pfctl -F all -f /etc/pf.conf | at now + 5 minutes

but i don't think that will work. However as soon as i reset using option "11" everything starts to work ( but ssh session breaks - oh well).

I imagine option "11" is a script? can i call it from cron and do my hacky workaround? if so where does it live? is this a system bug?
