Hi Everyone,
I am new to OPNsense and I am wondering if it can handle 10 Gbe (dl/up) Internet connection from my ISP via static IPV6.
Please note I am not a network pro, just someone who likes tech and fast internet :)
Thanks in advance.
Kind Regards,

It's more a matter of whether your hardware can handle 10gbe. OPNsense certainly can. I have a 10gbe port on an OPNsense router that functions perfectly well. It's on LAN side and used for VLANs, not WAN as it sounds like you intend, and it's connected to the switch via a Mellanox ConnectX-3 network card (which, incidentally, requires a tunable setting to be recognized), but it shouldn't make any difference which interface it's on. Also, IPV4 vs. IPV6 shouldn't matter. My ISPs provide IP addresses of both types through DHCP4 and DHCP6.
Again, however, I would urge that you make sure your hardware isn't going to bottleneck with 10gbe. Most modern consumer hardware should be fine, but if you have a low power device on which you intend to install OPNsense, there could be problems.
Hi Patrick,
Thanks a bunch for your reply. This is great news!
I have a dedicated PC running Intel i5 quad core with 4GB ram. It has Mellanox ConnectX-4 Dual SFP+ port installed on PCIE 3.0 x8. I plan to use this as the router to receive the internet connection from my ISP on the 1st port, and then DAC cable the 2nd port to my Mikrotik Switch with 8 SFP+
Is the 4GB Ram enough? or do you think I should put another 4GB?
Thanks once again.
You should be fine, then, except possibly for the RAM, which you mentioned. 4GB is low, and while it just meets the minimum hardware requirements for OPNsense, the recommended hardware requirements are 8GB, as discussed here: https://docs.opnsense.org/manual/hardware.html. If you can at all afford it, I'd upgrade the amount of RAM to at least 8GB or, better yet, 16GB.
Also, one other thing: Your Mellanox card is probably not going to be recognized out of the box. You're likely going to need to add the driver by configuring the mlx4en_load setting in tunables as discussed here: https://forum.opnsense.org/index.php?topic=21007.0.
Maybe it will be different in your case since you're using a ConnectX-4, but I certainly had to do this to get it to recognize my ConnectX-3.
Hi Patrick,
You're a star!
Thank you so much for all your inputs and for the links as well.
I will add more RAM on the PC and then start reading on the links you've provided.
