IPSEC performance

Zim

Hi,

We've got a cluster of UTM450's and UTM310's that have an IPSEC tunnel between them. The link is 1gbps, and we've verified we can get 1gbps over a single TCP stream. The IPSEC tunnel is capped at 500mbits though and can't go any higher. We've tested with some cheap Mikrotik routers and have achieved 800mbits. 

I've tested with IPS, Advanced Security, Wifi, etc disabled on both clusters and there has been no difference to performance. 

I've had a ticked open with Sophos support for a couple of months and now the tier 3/developer support are telling me 500mbits is the cap. 

Has anyone been able to get better than 500mbits IPSEC performance from a UTM? 

Thanks in advance.

    Hello Mark,

    Thank you for contacting the Sophos Community!

    Could you please share the Case ID!

    Hi Emmanuel,

    The reference is [ ref:_00D301GN6a._5003Z18HRNF:ref ]. Overnight it has been escalated to a number of teams, but I thought that someone might be able to confirm they've achieved those speeds with a UTM.

    Thanks,

    Mark

    Hi Mark - first post? - welcome to the UTM Community!

    Haven't tried, but at least let's look at some things.  Please show a picture of the Edit of the IPsec Policy you're using.

    Cheers - Bob

    Hi Bob, thanks for the welcome and for your help. We have tried a couple of policy combinations, but not extensively. Our current configuration is below:

    Initiating site (SG310 Rev 1,  firmware 9.705-3, pattern 192986):

              

    Receiving site (SG450 Rev 1,  firmware 9.705-3, pattern 192986):

             

    Many thanks for your help,

    Mark

    Hello Mark,

    Thank you for the Reference, actually, Case ID is 03269472

    I can see this was escalated to DEV and is being investigated under NUTM-12421

    At least you started with the best choice for speed among the standard policies.  I believe the processors in both units support AES-NI, so create a new Policy that uses "AES 128 GCM 128-bit)" for IPsec encryption.  I prefer to also use PFS when only using 128-bit encryption, so I would clone the "AES-128 PFS" Policy and make the new one look like:

    What's your throughput with that?

    Cheers - Bob

    Hi Bob. Thanks for the suggestion. Using iperf3, 20 threads to push the link, I'm seeing a touch under 500mbits:

    Thanks for sharing that, Mark.  I had expected a significant improvement.  Emmanuel, can we get an explanation?

    Hi , (A bit off-topic, but related to throughput issues on this thread.)

    I will setup a Sophos UTM VM later, but one thing, is AES-NI actually being used on UTM ?

    Related to this, on Sophos XG the AES-NI modules are loaded by the kernel, but none of the software actually uses it.

    More info at: https://community.sophos.com/xg-firewall/f/discussions/119782/hardware-acceleration-aes-ni-isn-t-being-used-on-the-software-version-of-xg-v18

    Thanks!
