Hi Experts,

My current lab setup as follows:

Home router with internet access.
A laptop with Ethernet and Wireless Card.
Proxmox as hypervisor
pfSence for firewall and VLANs.

My 5G router don't have any ethernet port. So i enabled wireless lan interface in proxmox. My configuration as below.

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

#auto wlan0
#iface wlan inet static
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/wlan0/proxy_arp

auto vmbr0
iface vmbr0 inet dhcp
bridge-ports eth0
bridge-stp off
bridge-fd 0

post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '' -o wlan0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '' -o wlan0 -j MASQUERADE

auto vmbr1
iface vmbr1 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0

Based on above configuration, i can access the proxmox ui.
I have installed pfSence successfully with 2 network interface vmbr0 and vmbr1.

Now i am trying to configure WAN and LAN in pfSence. but not getting ip for WAN. Tried with static and DHCP method. But noticed that no routing to proxmox or router IPs? Hence pfSense UI is not accessible.

Kindly assist to solve this issue.

Best Regards,
