Help with multiple NICS and VLANS

[phgsbr]

Hello, guys.

Sorry about my newbie doubts.



As you can see in above image, im running OPNsense on a Topton MiniPC with four 2.5gbps NICS. The first NIC is WAN, Second is LAN and left OPT1 and OPT2 without use. LAN is conected to a unmanaged gigabit swtich that distribute the connection to all devices on my home lab and my two Openwrt dumb APs. Two VLANs (iot and guests) are setted to this switch to use separated wifi in openwrt too. 

Now im building a Unraid Server to replace my old Synology NAS and some SBCs running docker containers. In Unraid PC i putted a 2.5gbps i226V NIC because i would like to my PC (with 2.5gbps network card) could comunicate with Unraid in 2.5gbps, using OPT1 and OPT2 to connect them.

I would like to know wich is the best way of take advantage of OPT1 and OPT2 and if is possible to keep PC and Unraid in same subnet of the LAN. I know that the best option is replace the switch for 2.5gbps one, but this devices are really expensive here in Brazil so i would like to use the Topton MiniPC NICS. I know that create a bridge with LAN, OPT1 and OPT2 is an option, but this way, i couldnt use the the VLANS, because VLANS cant be setted in bridges.

Somebody can help me?

Hiya

You may face some difficulty with doing this with an unmanaged switch.
Generally unmanaged switches don't do VLANs, (yours may be different of course!)
Your diagram shows only 1 input connection & 1 output connection.

Those topton units have multiple ETH interfaces, so your VLAN30 can be on a different connector.
However, the openwrt wireless boxes will be expecting TAGGED vlans on their only ETH interface.

Therefore I would suggest a mini managed switch, such as from Microtik, quite inexpensive, moderately easy to configure & would deliver the VLAN30 taged traffic between the firewall and the openwrt devices / guest users etc.
Other cheap & cheerful switches are available, e.g. managed switches are very reasonable on eBay...try HP1810G - only 1Gbps but does all the VLANs you need, and only £30.

Good luck with that.
