Boson Inter-Vlan routing Problem

pr3d4t0r

I'm trying to configure Inter Vlan routing in BOSON Netsim, but i can't. Every time i issue the command sh ip route in the 3550 switch, boson freezes...

This is my simple config.

Assume that Vlan2,Vlan3,Vlan4 exists.

ip routing

int vlan2
ip address 10.2.2.1 255.255.255.0

int vlan3
ip address 10.3.3.1 255.255.255.0

int vlan4
ip address 10.4.4.1 255.255.255.0

int fa0/2
switchport mode access
switchport access vlan2

int fa0/3
switchport mode access
switchport access vlan3

int fa0/4
switchport mode access
switchport access vlan4

The 3 PC's have 10.x.x.1 as the gateway.

I want to test some access lists also but i can't since boson keep freezes, at least could someone verify the config ?

My topology is : SW-->FW-->and so on...
