Hello,
Does anyone have recommendation for relatively cheap (could be used) and small (5-6 Ethernet ports since I'm limited with space) router that have at least 1x 2.5G LAN, 1x 10G LAN and 1x 10G WAN and support OpenWRT?
Wi-Fi is optional (would be disabled anyway)
Oh and I want to use 2.5G since I already have built-in 2.5G network in my PC, but if there is really nothing good that have 2.5G support, I could go with something with 2x 10G LAN and buy 10G network card to my PC
If you could relinquish to the 10G LAN port in some way may be the mikrotik rb5009 fits your needs. It has 1x 10G sfp+, 1x 2,5G and the rest are 1G Ethernet. Also its support by openwrt but I would give RouterOS at least a try.

Regarding the 10G LAN depending on your needs its may be better of in a DMZ anyway?
Maybe I won't even need 10 GB WAN so this could fit my needs, thanks
