I have a problem with port forwarding when I create VMs. When it comes to container it works. I'm using this configuration and it works fine.
auto vmbr2
iface vmbr2 inet static
address 192.168.0.254
netmask 255.255.255.0
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 '192.168.0.0/24' -o vmbr0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.0.0/24' -o vmbr0 -j MASQUERADE
# VM-WEB HTTP 80:192.168.0.1:80
post-up iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 80 -j DNAT --to 192.168.0.1:80
post-down iptables -t nat -D PREROUTING -i vmbr0 -p tcp --dport 80 -j DNAT --to 192.168.0.1:80
When I create a VM and bridge it with vmbr2 I can reach it but no internet "incoming no outgoing " with container it works just fine. Any ideas? 3 days working on it I gave up :)
