General Discussion / LAN Traffic & Bandwidth to Opnsense
« on: April 02, 2024, 02:43:55 am »
Hey All:
I don't (currently) use any VLANs.
Does the LAN NIC bandwidth in the Opnsense box need to be high to optimize LAN speed? Stated differently -- does a slower NIC bottleneck LAN speeds?
I have 1200mbps internet going to my Opnsense box via 2.5G NIC -- WAN.
The Opnsense box connects to a switch via 10G SFP+ cable -- LAN.
This switch then branches out to other switches, devices, AP's, etc.
But the main switch only has two 10G ports, and I was thinking it might make more sense for the NAS to use the 10G interface instead, and the Opnsense box just have two 2.5G cards.
Would decreasing the Opnsense LAN interface to 2.5G do anything to bottleneck LAN performance given I don't use VLANs and all LAN devices are on the same subnet?
