Hi Everyone,
I appreciate this is a very beginner question and there may be a few facepalms that will happen but I could do with some help.
We have just purchased a SG300-51 switch to enable our business to grow. I am attempting to setup 2 vlans (1 containing a router, the second just my pc for now whilst i test it).
For note, our router is managed so I have no control over this.
So for now Ports 1 - 2 are on vlan 1 under Access. Port 3 is under vlan 2 under access. I have switched port 3 to trunk but to no avail. All traffic is marked as untagged on all ports.
IP's assigned on vlan 1 are assigned from the router starting at 192.168.1.1 to x.x.1.254 (the router is at 254). The switch for vlan 1 is at 192.168.1.1.
IP's assigned in vlan 2 (by on board dhcp on the switch) are 10.0.10.1 - 10.0.10.254 (the switch setup to be 10.0.10.1).
I have a IPv4 static route of: 0.0.0.0 to 192.168.1.254.
Now i am sure I am missing something fundamental and I have been reading through article furiously to try and discover what is up, if anyone could assist and point me in the right direction I would be very greatful.
Thanks in advance.

I could be wrong, but I think he must already be in L3 mode since it appears he was able to assign interface IP addresses to both VLAN 1 and 10.
If your PC is plugged into gi3 on access vlan 10 then you need to use 10.0.10.1 as your default gateway and in your router/firewall you need a return route to 10.0.10.0/24 via 192.168.1.1

For intervlan routing and multiple layer 3 vlans the switch needs to be set in L3 mode , out of the box it comes as L2 , have you tried that yet ?
