A strange product, If I felt I had to use a rpi as a router(To be honest there are many other platforms I would choose before the rpi for a router) I would get a vlan capable switch, a pi4 and do the old router on a stick setup instead.
- hestefisk 4y agoWould you trust VLAN’s ability to securely separate and route traffic on the same port? I might be a bit old school but for this kind of stuff I really prefer proper, physical separation.
- somat 4y agoAs much as I would trust the router os to separate and route traffic across ports. or perhaps you mean the switch. in which case I would probably spot check ports to make sure the switch firmware was not doing something weird, but in general yes, vlans are well specified and commonly used and I would mostly trust the switch vendor to handle them is the specified manner.
- yabones 4y agoThe problem with the single-port router-on-a-stick is that it effectively cuts your throughput in half. 10/100/1000 is full-duplex, but since your traffic is going both ways on the same port you get 1G total rather than 1G in each direction. Having two gbe ports means you can get a full gigabit in _both_ directions at once. Not sure how often that would happen in the real world, but for some it may be worth considering... The other question is whether the hardware can do that kind of throughput... I've run for years on an old crusty J1900 with 3 realtek NICs onboard, and while it can saturate a 1G connection with bulk traffic, it does struggle to route small packets.
