Cannot access internet on container through proxmox host public ip.

[ryanjunior]

Greetings,

I am trying to make my containers have access to internet through proxmox host public ip. Below are my proxmox host networking configurations.

```
auto lo
iface lo inet loopback

iface eno1 inet manual

auto eno4
iface eno4 inet manual

iface eno2 inet manual

iface eno3 inet manual

auto vmbr0
iface vmbr0 inet static
address 207.45.76.20
netmask 255.255.255.192
gateway 207.45.76.1
bridge-ports eno1
bridge-stp off
bridge-fd 0


auto vmbr1
#private sub network
iface vmbr1 inet static
address 10.10.10.1/24
bridge-ports none
bridge-stp off
bridge-fd 0

post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '10.10.10.0/24' -o vmbr0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o vmbr0 -j MASQUERADE
post-up iptables -t raw -I PREROUTING -i fwbr+ -j CT --zone 1
post-down iptables -t raw -D PREROUTING -i fwbr+ -j CT --zone 1

```

And my container network configurations



But my container does not seem to have internet access. It cannot even ping my host private ip.
root@networking:~# ping 10.10.10.1
PING 10.10.10.1 (10.10.10.1) 56(84) bytes of data.

Can only ping to itself

rtt min/avg/max/mdev = 0.015/0.019/0.023/0.004 ms

DNS settings on the container looks like below.
root@networking:~# cat /etc/resolv.conf
# --- BEGIN PVE ---
search phxdcnet.com
nameserver 8.8.8.8
# --- END PVE ---
root@networking:~# ^C
root@networking:~# apt update
0% [Working]^C
root@networking:~# ^C
root@networking:~#

I have checked multiple posts on this forum, but none of them seem to work for me.

Can someone help me figure out what i am doing wrong above.

Thanks.
