GS316EP weird vlan behaviour

the switch is connect on port 1 to a HP Pro-Curve-Switch-2510G-48 with pvid 222 and some tagged vlans.

I set up the GS316EP the same way: pvid 222 and the other vlans tagged.

with a static ip, i got 3 pings back one with each vlan:

The switch is set up using dhcp:

here is the log from one of the dhcp-server. the ip 192.168.0.135 is from another network with an own dhcp-server
