Hello,

I am playing with my configuration and I am not able to get assigned subnet to work. My configuration:
Code:
auto lo
iface lo inet loopback

auto enp4s0
iface enp4s0 inet manual
        bridge_stp off
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up echo 1 > /proc/sys/net/ipv4/conf/enp4s0/proxy_arp

auto vmbr0
iface vmbr0 inet static
        address 136.x.x.20/26
        pointopoint 136.x.x.1
        gateway 136.x.x.1
        bridge_ports enp4s0
        bridge_stp off
        bridge_fd 1
        bridge_hello 2
        bridge_maxage 12

# for a subnet
auto vmbr1
iface vmbr1 inet static
        address 162.x.x.32/29
        bridge_ports none
        bridge_stp off
        bridge_fd 0
Assigning IPs to VMs which are from 136.x.x.x range works without issue (they have the same gateway), but if I try to assign to a VM IP from the 162.x.x.x range, where the gateway is 136.x.x.20 I am not able to reach from them the network (i.e. ping on gw 136.x.x.20 does not work).
Is there something I miss here? Thank you!

This is normal, as they are not on same subnet. why don't use simply use 162.x.x.32 as gateway for ips address in 162.x.x.x range ?
