Unable to connect to LXC plex container in Proxmox through public IP address

I have a cloud server running Proxmox with a LXC plex container connected to vmbr1 with IP address 10.0.0.2/24. I'm trying to connect to the Plex GUI through http://:32400/web but I can't even ping the VM at 10.0.0.2 from the Proxmox shell. My interfaces configuration is below. Do i have it configured incorrectly?

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

auto eno0
iface eno0 inet static
    address <Public IP>
    netmask <Public IP netmask>
    gateway <Public IP gateway>

    # Enable IP Forwarding
    post-up echo 1 > /proc/sys/net/ipv4/ip_forward
    post-down echo 0 > /proc/sys/net/ipv4/ip_forward

    # NAT Configuration
    post-up iptables -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
    post-up iptables -A INPUT -p tcp -m tcp --dport 8006 -j ACCEPT
    post-up iptables -A INPUT -s 10.0.0.0/24 -j ACCEPT

    post-up iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

    # Clean up rules on interface down
    post-down iptables -D INPUT -p tcp -m tcp --dport 22 -j ACCEPT
    post-down iptables -D INPUT -p tcp -m tcp --dport 8006 -j ACCEPT
    post-down iptables -D INPUT -s 10.0.0.0/24 -j ACCEPT

Have you tried the ping without any IPTABLES rules in place, only vmbr1 selected and just the default NAT config in proxmox ?

What are you trying to do with the auto vmbr0 and vmbr1 rules ?

I did have a similar setup a while ago, however I don't remember using any firewall rules or similar. Selecting the bridge (vmbr1 in your case) along with DHCP routing in the Network section should do the job.
