We have a vlan 11 with a DHCP range of 10.11.20.1 - 10.11.254.254 default gateway of 10.11.0.1.
all clients that have an IP address of 10.11.0.x and work fine. All clients that get an IP of 10.11.1.x cannot ping anything (server, gateway, printers, not internet) or be pinged. All client on vlan11 have the same default gateway.
We have a Cisco firewall and cannot find any settings that could be causing this issue. Of course I could be overlooking something.
Not sure if the core switch would do anything. DHCP and DNS are controlled by a windows 2008 DC.
