General VLAN / Network question

[thomka]

Hi Community,

First of all: I am not so experienced in this topic, so please appologize my (maybe) beginner question :-)

Following situation:

I would like to use a SBC with two 2.5gb NIC‘s as my new OPNSense FW. In OPNSense I would like to define my vlans.
The SBC is connected to my network (I would like to use 2 MikroTik CSS610-8G-2S+IN switches). The link between my switches will be a 10gbe fibre (sfp+ modules).

Does the opnsense connection to my network (1gbit or 2,5bgit)  possibly effect the 10gbe connection between my switches? Or in other words: is the opnsense —> switch connection a bottleneck which will effect the 10gbe switch-to-switch uplink?

Thanks in advance and best regards,
Thomas

The connection between the switches will always be at 10gbe.
But if your routing between vlans via the OPNsense, then the speed with be whatever the OPNsense is connected at 1gbe.
