SG350 - Inter-VLAN communication not working

Dear all,

I will indulge in a little spot of cross posting, since I just now figured out, that my original post might be better placed here.

I will recap the issue as follows:

 

I have a RV260P as a router/firewall running two PoE devices (DECT base and a WiFi AP). Port 8 is a trunk that is connected to my SG350 switch on uplink/port 25. I have configured VLANs on the router (VLAN 1 as default, VLAN 10 => 192.168.10.0/24, VLAN 20 => 192.168.20.0/24) with the routers VLAN interfaces set to each 192.168.VLAN.1.

The switch has the same vlans configured but the VLAN interfaces on the switch have their IPs as 192.168.VLAN.2.

My PC (192.168.10.20) on port 24, which is untagged VLAN 10 can access the internet through the trunk and router.

 

Using the switches ping tool, I can ping a media server on port 1 (untagged VLAN 20 => 192.168.20.10) when the source interface is set to VLAN 20 (192.168.20.2).

My PC can ping the VLAN 20 interface. But I cannot ping the media server from outside VLAN 20. Not from my PC and not from the switch itself, using a different VLANs interface.

 

According to all the TechTalks-videos this should work out of the box (but they do not show us the detailed ping outputs in the videos, we have to take their word for it).

 

So the simple question is: What am a overlooking or how can I configure everything in a way that my router does all the routing (In IPv4 routes I cannot specify the router's VLAN interfaces as next hop).

 

Thanks to everyone in advance!

Update: It is working now, I had to activate "enable multiple gateways" on my Synology RS819, to have a gateway for each of the interfaces on there.
