From the Vlan 44 interface I am not able to ping the Vlan 3 interface of the Core Switch

Hi everybody;

I have the following scenario (IP's are fake, is only orientative example), i am implementing a new mobility express topology because in our company everybody is still using ethernet cable :S, the following topology is that:

    Laptop                  ------        WLC                           --------      Switch 1                      -------          CORE

Ip Address                                DHCP Pool                                     Int Vlan 44                                           int vlan 3

192.168.45.231                       192.168.44.0                                 192.168.44.2                                 192.168.3.1/24

255.255.254.0                         255.255.254.0                               255.255.254.0

GW                                           GW                                                Int vlan 3

192.168.44.2                           192.168.44.2                                 192.168.3.4/24

Vlan 44                                     Vlan 44                                          default router to:

                                                Management vlan 10                       192.168.3.1

                                                192.168.10.90/24

                                                 Default GW for vlan 10                 Management vlan 10

                                                 192.168.10.22/24                        192.168.10.22/24

From the test laptop i am able to ping his GW 192.168.44.2 and the IP 192.168.3.4 but i am not be able to ping the CORE Ip address 192.168.3.1.

From the Switch 1, obviously i can ping the IP 192.168.3.1 from the Core, and even i can ping 192.168.3.1 source 192.168.44.2

On Switch1 the use default ip route to the ip address 192.168.3.1 (interface vlan 3 of Core)

On Core i use this static route:

ip route 192.168.44.0 255.255.254.0 192.168.3.4

What's wrong? I forgot something? I only use in this case static routes.
