Review: Works well with true multi-OS driver support including Windows Server. - Was looking for a 2.5gbe NIC that would work fine with Windows Server 2019 due to the 2 NICs built onto the motherboard not being compatible with Windows Server family (thanks Intel for purposely doing this so users are pushed towards proper server platforms instead of using a consumer one). The Realtek chipset used on this NIC installed without any hassle once got the drivers from Realtek’s global website. granted you will lose available PCIe lanes so may not be for someone that wants to keep 16 lanes for their GPU & multiple NVMe drives on a gaming rig, but general usage overheads are low and no worse than an onboard NIC (a lot of the cheaper NICs rely on software & the CPU to control traffic etc but this seems like a true hardware controlled NIC). Doesn’t seem to slow down under load either which a lot of cheaper cards can do as the controller gets hot, but this shouldn’t be a problem if got sufficient cooling in the case. Very happy with the performance of this NIC and will be buying more of them when required to either upgrade from Gigabit to 2.5gbe connectivity or replace a failed onboard NIC.
Review: Perfect for UnRaid server - Easy to install, works really well and good value for money, what's not to like! Used in UnRaid server with 'RTL8125 Drivers' plugin and works flawlessly at 2.5gb/s

**Q: Do the 2 physical ports appear as 2 separate interfaces in the os - i.e. can i have 2 separate ip addresses and route between them (unix)?**
A: Dear customer,
Thanks for your question. 
Yes, you can have 2 seperate ip addresses. What do you mean " route between them “ ？ Usually, this has nothing to do with the hardware network card, you should check this with the system.
Hope our answer helps.
