Reflexion will be End-of-life on March 31,2023. See Sophos Reflexion EoL FAQs to learn more.
Reworked overview of my part - We are working now 2 weeks on the Sophos Switch to get it configured to apply to our customer situation:
Still existing problems:

Here is my sequence until i run into the error/problem - hopefully some can give us any hint on it:

Note: If you not stop here and wait you will see errors like this:

After adding the 4th vlan interface we always face this error message - same to local Web UI !

We have also opened a ticket and also escalate it but from Sophos until now only unqualified replies!I am wondering that in this Switch section only people are reviewing but it looks to me most are also try to understand the product !I also hope we can exchange here more experience with the switches
Short Update:Feature is now present but with the known limitation to 3 IP vlan interfaces! the 4th IP is for the switch management reserved - Also Central support this configuration now!PS: For myself and my customers this is definitely not enough, and we never configure routing on a firewall! So we still use other brand for L3 routing

I would like to meet guy who decided to have 3 VLANs with IP addresses . We got some switches and returning them back to Sophos requesting full refund as well as to cover all cost for shipping, returning, customs and VAT we have paid. They are doing false advertising. that's wrong and punishable by the law .
With this info, we would actually purchase Fortinet firewalls and switches. We will return these devices and ask for refund and additional cost we have. And we will never purchase these devices anymore.
and really: How came up with this:
Yes - all models(IPv4: 59 entries for static route, 4 entries for interface route and 1 entry for default route.)(IPv6: 5 entries for static route, 16 entries for interface route and 1 entry for default route.)
what is business and technical explanation for this setup?Since based on this, 8 switches will be returned and cca 100 canceled.
I am sorry, if you was misleading by the information. Sophos does not offer Core Switches.
But again: I would recommend to look into your network security and not rely on a core switch routing anymore. It will not protect you against any kind of lateral movement.
And the technically explanation is easy: This is not the focus nor the application field of this switch. Access Switches are not designed to do routing at all. They rely on a core switch // a firewall to do this job.
LuCar Toni said:It will not protect you against any kind of lateral movement.
Not even if we are running Intercept-X EDR, XDR, MDR?
You should always build up multiple layer of protection. Endpoint will do its best to protect the endpoint. But you will be completely open for network based attacks.
For example: Eternal Blue / Wannacry was a 0-Day Lateral Movement attack. Therefore it could spread through the entire network, if you rely solely on your core switch. Network segmentation will not stop it, if you have nothing to filter.
You would need a firewall in between.
Something nice to read about the difference: https://www.reddit.com/r/HomeNetworking/comments/q8pypp/is_there_any_significant_difference_between_a/
Nowadays: Core switches are moving more towards firewalls. Simply because back in the days, a firewall could not offer the needed backbone speed. But XGS Hardware and other vendors can do this now. So if you have for example SFP+ in your network, SFOS can route this AND protect the network.
Sophos currently does not look into the core switch segment, as we can protect the network with access switch + Firewall. There are still use cases for core switches to "connect to the firewall" but in the end, the L3 Routing does the firewall, as it can do more with the traffic than simply route.
LuCar Toni said:Sophos does not offer Core Switches.
Looks like Sophos has new definition of core switch.
LuCar Toni said:Access Switches are not designed to do routing at all. They rely on a core switch // a firewall to do this job.
why then are you bothering with those 4 routes you have?
LuCar Toni said:Access Switches are not designed to do routing at all.
this is maybe case with Sophos switches. Not with rest of the vendors.
LuCar Toni said:They rely on a core switch // a firewall to do this job.
Routing on XGS is another game
I will not do any kind of convincing toward your position. I just tried to explain your the situation. If you want to discuss this further, please reach out to your sales rep.
You just need to have proper documents available and correct. People makes decision based on those information,. That's all. Your sales reps either gone or went to work for competition.
We will update the docs shortly to reflect this in all documentations.
Thank you. Next time try to do it correct first time.
