better post config in attachment.

with "ip routing" active, "ip default-gateway 172.16.1.253" in the switch config will be ignored , you must use "ip route 0.0.0.0 0.0.0.0 " instead.
(not configure default-gateway but default-route wich does the same thing).

then you have "ip route 172.16.0.0 255.255.0.0 172.16.1.254"
but many adresses from 172.16.0.0 are local
vlan 60 ip address 172.16.60.2 255.255.255.0
vlan 61 ip address 172.16.61.2 255.255.255.0
vlan 90 ip address 172.16.90.2 255.255.255.0
vlan 91 ip address 172.16.91.2 255.255.255.0
vlan 70 ip address 172.16.70.2 255.255.255.0
vlan 71 ip address 172.16.71.2 255.255.255.0

you may want to change "ip route 172.16.0.0 255.255.0.0 172.16.1.254"
to "ip route 0.0.0.0 0.0.0.0 172.16.1.254"

many vlan's are only "tagged A1" and no other ports (untagged or tagged).
what's connected to A1?

but then all vlan's will be able to route.
As the 4202 does not support ACL's you cannot limit access between vlan's.
So what you want cannot be done with the 4202

Thank you for your reply, on tagged A1 i have 9 procurve 2810-24g. to the different vlan. So event i if i use a router like 2003 server and trunk all my vlan on a port can't i control the trafic with that ? like using ospf or rip to route all the vlan on vlan 3 and vlan 99 ?

Or if you have an other solution iam open :) THANKS you

If you use a router (or switch) that CAN use ACL's, then you can control trafic to allow only traffic between given vlan's.
with the current switch it's all or nothing.

The switch can do port-based acces-control
If you put different ports in a different vlan than you can configure if this port may communicate with the trunk (A1).
Wich may do almost what you want.

I've no knowledge about w2k3 routing to answer if it's capable of using ACL's
