I have a server within OVH network. Proxmox 4.3 was installed there as a supervisor and it's hosting 2 LXC containters. Both are running in 192.168.11.0/24 network setup on vmbr2 network for which I have also setup NAT like that:
auto vmbr2
iface vmbr2 inet static
address 192.168.11.1
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 '192.168.11.0/24' -o vmbr0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.11.0/24' -o vmbr0 -j MASQUERADE
I've also bought Failover IP from OVH, setup virtual MAC for it and assigned it to one LXC container (vmbr0 interface).
My problem is that I can access this IP on LXC server where this IP is assigned (obviously), but I can't do that from other LXC server. Connection just timeout when I simply do wget to it.
What am I missing in my configuration?
