Open Stack

You can, just tell neutron you want to have another external network. Lets
say VLAN=300 is 192.168.66. <http://192.168.66.0/24>0/24

# Creating the external network type VLAN with VLAND ID == 300
# The name of the provider physical_network "ext" is mapped to a physical
# device on the ML2 configuration file of each network node

neutron net-create \
    --provider:network_type vlan \
    --provider:physical_network ext \
    --router:external \
    --provider:segmentation_id 300 \
    ext_net_300

# Define the IP range for floating IPs available on that network, the
gateway,
# DNS nameservers and CIDR, and no DHCP (in this case)
neutron subnet-create \
--allocation-pool start=192.168.66. <http://192.168.66.0/24>10,end=1
92.168.66. <http://192.168.66.0/24>255 \
--ip-version 4 \
    --gateway 192.168.88.1 \
    --disable-dhcp \
    --dns-nameserver 8.8.8.8 \
    --name ext_net_300_subnet \
    ext_net_300 192.168.66. <http://192.168.66.0/24>0/24

Then the users will see 2 (or more) floating ip pools ...
