RB1100AHx2 - Routing performance

RouterOS Beginner Basics
1

Hello everyone,

I am a new member in the Mikrotik family, so please, help me out with a question I am asking myself.
I have 5 Public IPs, currently routed by the ISP
My ISP keeps changing the IPs so I am thinking to purchase a small subnet of 8 IPs and route them with a RB1100AHx2 (http://routerboard.com/RB1100AHx2).
With a subnet, the ISP will provide only 1 directed connected IP through which I have to route the subnet, but in case the main directed IP will change in the future, I will not have to reconfigure all machines behind the router.
Behind it, I will have 5 machines with public IPs, each machine with it’s own firewall.

Question:
I have a 150 Mbps guaranteed service up to 1 Gbps.
Does a RB1100AHx2 handle gigabit routing with ease? No NAT, no firewall, no DHCP, just routing.

I know the MikroTik gives the performance numbers, but I would like to hear it from a client :slight_smile:

I know it’s a late question, as I have already purchased the device, but until tomorrow when it will arrive via courier, I would like to sleep at ease :slight_smile:
Thank you.

Just got the unit and did a some basic tests at home, on a residential internet, until I get to work.

Setup the unit with P1 as WAN and P6 as LAN with NAT and DHCP on P6

Network basic diagram

FO Converter @ 1 Gbps —> Asus RT-AC68U 1 Gpbs (PPPoE account on WAN) — > MikroTik RB1100AHx2 (P1) @ 1 Gbps —> Computer with Intel(R) Gigabit CT NIC @1 Gbps

Download = 933 Mbps
Upload = 100 Mbps (max upload limited by ISP at 100 Mbps)

Also, the latency from the PC to the router was a constant 1 ms during the test.

CPU load on the router 70%

So far I think the unit will handle routing at 1 Gpbs with a public subnet given that it can handle almost 1 Gbps with NAT.
Thus, happy customer here.
Hope it won’t fail for a long time.

Yes, it does.
I get around 920 Mbps on a 1 Gbps link, including NAT and firewall filters, and it doesn’t max out the CPU.
Overall a nice device.
