At the moment, user devices have multiple IPs if they need to access multiple services.
All devices are physically connected into to the same switched network. I know it's bonkers and am pleased to say it had nothing to do with me.
I am introducing a pair of servers, to act as router/proxy/firewall/vpn, replacing a lot of existing archaic infrastructure.
I've reached a point where I can either do this:
# using physical ports eth0 - 10.0.0.0/24 # The main network, dhcp'd user devices live here. eth1 - 172.16.0.0/24 # a couple of out-of-scope routers in here. eth2 - 192.168.0.1/24 # in-scope and out-of-scope servers and stuff. eth3 - 81.x.x.x/x # internet facing
# using virtual ports eth0 - 10.0.0.0/24 eth0:0 - 172.16.0.0/24 eth0:1 - 192.168.0.1/24 eth1 - 81.x.x.x/x
Considering the server pair, the first option requires 8 interfaces/8 switch ports while the second option only requires 4 interfaces/4 switch ports.
What should I be considering when making this decision?
