I am have one SG-300 switch with the following setup;
Layer 3
IP4 Routing is enabled
VLAN 20 192.168.2.100 255.255.255.0
Windows 7 workstation 192.168.2.150 255.255.255.0 Gateway: 192.168.2.100
VLAN 30 169.254.3.100 255.255.255.0
Windows 7 workstation 169.254.3.150 255.255.255.0, Gateway: 169.254.3.100
I can ping from the VLAN 30 wokstation to both 192.168.2.100 and 169.254.3.100
From the VLAN 20 workstation I can only ping 192.168.2.100
Niether workstation can ping each other.
All firewalls and Windows defender are are off and disabled.
Any ideas would be appreciated.
Thanks!

Thanks for responding to my post.
The following is the information that you requested;
The VLAN 20 workstation does have a default gateway configured.

Strange that the VLAN 20 machine reports destination unreachable in the first attempt, I was expecting it to at least hit its default gateway (192.168.2.100) before any failure. Similar to the machine on VLAN 30.
Is this switch connected to the Internet?
Can you post the switch config?

OK, I believe I have resolved the issue.
The issue was directly related to using a 169.254.x.x address, non routable IP range, for the one VLAN.
I won't get into the reason why I was using that address range but once I changed it, all inter-VLAN routing was working without issue.
Thanks again for the help!

Sweet. Glad to hear.
I was suspecting that being the cause, hence the reason I asked if the switch was connected to the Internet. Probably conflicting with another host. 169.254.x.x is routable on the Internet.
