SG-2100 vs SG-3100 vs SG-5100... ? Purchase advice needed

stephenw10

ISPs providing exactly that do exist but I don't think we have ever tested one with a SG-2100.

I love to hear about it if anyone has.

I read this "extensive" post for this to work here in Spain. Finally a company called Carlitoxx-Pro started shipping a GPON to GigabitEthernet device. There is also a ZISA one that is sold online from China:

https://forum.mikrotik.com/viewtopic.php?t=116364

It is from Mikrotik, but all the electronics are inside the device so I think it should work while the SG-2100 provides power to the GPON.

I've seen that UniFi also sells a GPON to Gigabit adapter but I don't know if this one could work on a SG-2100:

If you look into the data sheet, there is a GPON for ONT side, not for OLT. But I don't know if this SFP could work against "non-unifi" OLT's.

But yes, I think it is "doable" :) for the moment I am using a UF Loco ONT and connect my SG-2100 straight to RJ-45 cable, but maybe in the future I'll try one of those.

BR!

I’m running a SG-2100 with a 1000Base-BX20 SFP in the SFP slot that connects my fiber to the home directly. As the tranciever indicates, my ISP uses single strand Gigabit Ethernet to the edge.

Nice!

I tested some BiDi modules here and they worked without issue.

Steve,

Do you know if the 1G BiDi will work with the XG-7100 1U? I've having some issues using the "generic" ones from FS.com. I've started another thread but haven't heard anything.

Though I was quite surprised about that. It doesn't report a link speed so cannot be set to 1G fixed which is often required for use like this.

@stephenw10 Good to know it's possible! Have you been running this without any issue?

stephenw10

Not for any time. I just moved it from an SG-2100 to test. I saw no problems though and it also runs fine in the SG-2100, been running there for months.

@cabledude
You may be able to do the SG-3100 but only if you offload Suricata and/or nTopNG to a separate machine. Otherwise, go with the 5100 as suggested earlier.

I speak from experience, as having tried it before. ;)

Biggy823

@msf2000 I too happen to be in the same boat. I have the SG-3100 and currently experiencing lock ups and random reboots. It just does not have the horse power needed to run these applications. I am now facing the hard choice that I am going to have to upgrade to the 5100. Don't make the same mistake that I did.

@msf2000 SG-3100 is not good for me. I just installed one for customer and was trying to get decent IPSec speeds between installed 3100 at 200Mbps fibre site and 500Mbps fibre remote site using SG-5100. I was only able to achieve around 80Mbps throughput. I had tried at home for a while where I use a home built pfSense. I try connecting SG-3100 to our work SG-5100 - both sites are 1Gbps fibre. With my home build setup I get around 700-800Mbps IPSec but with SG-3100 could not get any decent speed at all. Older SG-2220 is way better around 400Mbps IPSec but it is limited to around only 700Mbps LAN routing so I could never hit full 940Mbps in Speedtest. I wish Netgate would come out with inexpensive line of routers using the Intel CPU with good IPSec encryption instead of these ARM processors. Maybe SG-3100 work good connecting IPSec to another SG-3100 and maybe when I have time I can test a 700Mbps site to a this 200Mbps site both using SG-3100

The biggest trouble with the hardware offerings is that there is a world of difference between an Atom cpu and a Xeon. Atom can hardly keep up with moderate home use; and there is literally nothing in the lineup for full wire speed home without going up to a much more enterprise capable Xeon. The 5100 is really the lowest priced NICE machine in the lineup that can pretend to keep up with crypto.

I think something with Ryzen V2000 series embedded processors would be much more appropriate for long term use. Engineering team...please hear my prayers...

The Hardware Crypto offload in the SG-3100 supports AES_CBC do you use this?
I guess you have set up the IPsec with AEC_GCM and then, the SG-3100 have it run in slow software mode.

@nocling

Yes I tried AES and SHA1 for encryption and did not get expected results.

Could be that the other end, SG-5100, is doing software crypto with these settings and is the bottleneck? I am thinking SG-3100 to SG-3100 may be a good test to do when I get the chance.

NOCling

I don't think so. the Atom of the SG-5100 supports AES CBC to.

After upgrading a few SG-3100 to 20.05 it seems to have resolved my issues with VPN speed, and I get expected IPsec VPN performance now.

SG-5100 is still far better if can justify the price.
