Routing between two networks over 1 physical interface not working anymore

astrakid

hi,
after a total outage of my server i recovered mostly everything. one step is missing, and i am sure it is the configuration on my hypervisor.

i am running a single server system with proxmox. in a virtual machine pfsense is doing all the stuff (simple firewalling, dhcp, dns, ...).

proxmox: 1 NIC
pfsense: 2 virtual NICs (LAN 10.1.1.4/14 and WAN 192.168.1.2/24)

the wan router and all devices are connected to the same switch. all requests from my LAN to WAN are forwarded to the default gateway (pfsense). pfsense forwards the to the wan-router.

hypervisor network configuration:

iface enp3s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 10.1.1.2/14
        gateway 10.1.1.4
        bridge-ports enp3s0
        bridge-stp off
        bridge-fd 0
        dns-nameservers 10.1.1.4 192.168.1.1

pfsense has vmx0 (LAN) and vmx1 (WAN).

it looks all fine from my perspective, but route requests to WAN are not transferred to WAN-gateway.

is the main cnfiguration right? i compared with my backup, and i can't find a difference? i tried to get it all up and running for about 12 hours now... my children are getting angry.

regards,
andre

oh man... i guess it was a reboot that i missed after changing ipv4_forward in sysctl.conf to 1 - or just do a sysctl -p... however it works now
