I have been asked if there is a solution to expose a single machine (Linux Server with honeypot installed) to multiple VLANs, I mean, a single machine will have many IP addresses belonging to each VLAN. The goal is to host a honeypot to every VLAN which exists in the network.
I have a Linux box with a gigabit Ethernet card (let's say
eth0), and I thought maybe using virtual interfaces configured like this:
eth0:1 -> IP 10.10.0.15 / GW 10.10.0.1
eth0:2 -> IP 10.10.1.15 / GW 10.10.1.1
eth0:2 -> IP 10.10.5.15 / GW 10.10.5.1
and so on. So each VLAN might be accessible within each one of the virtual interfaces.
Is this even possible to achieve with the default Debian 9?
