First of all, thank you vpx23!

Little Update from my side:

I went with the E810-CQDA2 , before reading vpx23´ answer :/ and overlooking the limitation in my own research.

I can confirm that the card is fully working with the ice driver of OPNsense 23.7. It is also possible to turn on the "breakout" mode eather with the epct(64e) tool using the cli or on most mainboards directly.
I am using an ASRock Rack B650D4U-2L2T/BCM  with a ryzen 9 7950x.

With the current card i can turn on the 2x4x10G Mode which results in 8 interfaces (ice0-7) that work with "BlueLan 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout" cables. The single links are limited to 10G in that case. It is enough for my needs since i mainly needed 8 interfaces.

Unfortunately the manual of the ASRock Rack B650D4U-2L2T/BCM does not speak of bifurcation, but there is an option inside the AMD PBS submenu called PCIE/GFX Lanes Configuration that can be set to x8x8. Since the board does not have another 8x pcie slot I am hopefull the E810-2CQDA2 will work in that and allow 2x4x25G then.
I might be able to confirm that at some point, since i am building 3 systems.

Hey everyone,
I am in the process of designing a very fast machine for use as a transparent bridge within a multi 25gig network. Since in bridge mode vlans dont work, i am going to split the existing vlans into individual ports on the switch side and loop them through the Opnsense. Since i need more than the 2 vlans (2P = in and out per vlan) and only have a slot for 1 card in the 1u server the e810 xxvda4 4x sfp28 ports are not enough.

There is a version of Intel e810 that hat 2x qsfp28 (100gbit). For this breakout cables do exist that split qsfp28 into 4x sfp28.
Does anyone have experience with the new e810 Intel cards and if they work in breakout mode (as 4 individual lan interfaces) ? In theory it should give me 8x sfp28 interfaces that can be bridged.
Intel Website says the card is fully supported but well, that is a rather uncommon usecase.

Thx!
