Can I use an HP t730 for 1Gb internet and OpenVPN routing?

reasonable good VPN connection

Depends what you mean by that. VPN is going to be the toughest requirement to meet there especially if it's OpenVPN.

How are you going to be using OpenVPN?

Just routing/firewall/NAT at 1Gbps doesn't require that much CPU. A C2D E4500 will do it for example.

hi,

the minimum requirement is two ethernet ports (LAN, WAN)

in this "iron" HP is just on motherboard offers one port eth. (I haven't even found what ethernet controller chip it uses)
with expandable optical connection NIC (Allied Telesis - M.2 f.faktor)

this addon (NIC) is not known to be supported by the version of FreeBSD used
https://www.amazon.com/HP-AT-27M2-Ethernet-839040-001-811416-001/dp/B071RS4MJG

USB network adapters I never use in an NGFW installation - I just note, because I don't see any other expandability for this HP unit

BTW:
-HP uses rather grumpy, fixed hardware solutions (to protect the brand)

Looks like the HP is setup up with a Realtek NIC (RTL8111HSH-CG), go for Intel PCI NICs and use it for management only.

@NOCling

the forum is full of posts on why not do this:

Realtek NIC (RTL8111HSH-CG),

this PCIe x8 slot seems pretty unreachable for normal low profile and full height expansion cards:

Ive got these units in several locations all tethered together quite happily using OpenVPN.. All of them with multiple subnets on site.

The one with a 1gig connection does full speed available from the connection as compared to a laptop direct to the modem.. But I use a 4 port card in all of them..

Hi,

do you need to unmount the NIC front plate for this?
or can be inserted without modifications?

BTW:
otherwise your "avatar" picture is nice
Do you deal with WISP?

chpalmer

Do you deal with WISP?

I do anything tower related. Though usually bigger antennas.

The card I linked to comes with a half space plate that can be changed out.

@chpalmer

thanks for the answer...
I also like big antennas, especially UHF-FM and mobile sector radiating antennas

I built this about 15 years ago

@stephenw10 are you aware of any CPU able to push 1 Gbps OpenVPN traffic in a single session?

Ive been working these things for almost 30 years. Still love the view! We do mainly LMR but dive into most anything that someone needs to be put up. Cameras included..

Sorry for the hijack mhweb..

@Rico

Now?
there is no such....

AMD RX-427BB with AMD Radeon(tm) R7 Graphics
4 CPUs: 1 package(s) x 4 core(s)
AES-NI CPU Crypto: Yes (active)

This is one of mine in service..

@Rico Not anything I have access to.

There probably are things that have fast enough single thread performance to do it.

If we assume it scales we could probably guess at what is required...

I would expect to need a score there of at least 2200 to get close to 1Gbps using AES-GCM in ideal conditions. Which isn't too wild a requirement. More data needed!
