intervlan routing on 5304xl

[Bilotta Alessio]

got three switches Procurve 5304 and one 2512
My net has all static ipâ s.
Domain Controller 192.168.10.5
Backup Domain controller 192.168.10.7
Gateway 192.168.10.1 (Switch1 vlan10 ip)

Gateway for Hostâ s: every host has the gateway set to its own vlan.

I set four VLANâ s on all switches with those IPâ s

Switch 1 (Main)
VLAN10 192.168.10.1
VLAN20 192.168.20.1
VLAN30 192.168.30.1
VLAN40 192.168.40.1

Switch 2
VLAN10 192.168.10.2
VLAN20 192.168.20.2
VLAN30 192.168.30.2
VLAN40 192.168.40.2

Switch 3
VLAN10 192.168.10.3
VLAN20 192.168.20.3
VLAN30 192.168.30.3
VLAN40 192.168.40.3

Switch 4
VLAN10 192.168.10.25
VLAN20 192.168.20.25
VLAN30 192.168.30.25
VLAN40 192.168.40.25

All my servers are connected to switch 1 (Main). On two of my servers I Installed Kerio WinRoute Firewall, the first to access the Internet and the other to access a Remote LAN through a Modem HDSL.
Internet Server has the network interface with IP 192.168.10.4
Server to access the remote LAN has the network interface with IP 192.168.10.11.

On my switch 1 (Main) I created the following static route:
0.0.0.0/24 192.168.10.4
10.0.0.0 / 8 192.168.10.11

(At the moment all my host's are assigned to VLAN10 and everything working nicely).

I enabled the IP routing on all the switches, I assigned the gateway to the hosts for their own VLAN, but Iâ m not able to ping host's in different VLAN's. Finally I enabled the GVRP, now I can ping hosts' from vlan20 to vlan10 but not vice versa, and especially Iâ m not able to ping servers with Kerio installed (192.168.10.4 and 192.168.10.11) by vlan20, 30.40.

What's wrong? Do you have any other suggestions to complete this VLAN routing? Do I have to enable the proxy-arp?

Any kind of suggestion will be appreciated.
