Are there any disadvantages to using a single NIC with VLANs rather than two NICs for a router?

- SteveNuts 9y agoMostly just bandwidth, if you have a dedicated storage device it's pretty easily to saturate a 1Gbe NIC.
- paulfurtado 9y agoMy one complaint is the lack of plug sensing: if you unplug a cable modem and plug it back in, that typically does things like triggering a DHCP request, which doesn't happen when the cable modem is plugged into a switch port on a vlan.
- azdle 9y agoIt's also easier for misconfigurations to lead to security issues since your switch resetting to default means your network is now connected directly to the internet. I had this happen after the power went out last time, luckily I'm on a PPPoE connection so it wasn't really connected to the net. Replaced my NUC + managed switch setup after that.
