Routing between VLAN Hp1950?

Question

Computer networks

We have 2 HP 1950 in the stack. VLANs, VLAN-Interfaces are configured.
ACLs are also specified but not included in the packet filter.
Create a static-route on the router to the Internet in vlan 400 (vlan interface 192.168.1.1)
From the cli of the switches, ping to the external network and to the router (192.168.1.1) goes. If you remove static -route disappears, as intended.
With VLAN1, which is acceptable by default, we see vlan-interface 192.168.1.2 (this is the vlan 400 interface, and packets do not go further).
I am attaching the configuration.
