Subject Re: SSVM cant route to MS, Iptables keep self-updating
Date Tue, 05 Apr 2016 13:31:56 GMT
I think so. network/interfaces file on host/MS:

auto lo
iface lo inet loopback

auto eth0.100
iface eth0.100 inet manual
        address 172.16.135.179
        netmask 255.255.255.0
        gateway 172.16.135.254
        dns-nameservers 172.16.238.7 172.16.238.6

# Public network
auto cloudbr0
iface cloudbr0 inet manual

 bridge_ports eth0.200
 bridge_fd 5
 bridge_stp off
 bridge_maxwait 1

# Private network
auto cloudbr1
iface cloudbr1 inet manual
    bridge_ports eth0.300
    bridge_fd 5
    bridge_stp off
    bridge_maxwait 1
