ICMP

I have an RD3011 UIAS-RM with 40 VPNs connected. When I send a ping from any station, to any of these VPNs that are turned off, the command
is normally accepted. What could it be?

What station ? So VPS are connected or turned off ? What command is accepted ?

too little information to understand where the problem is. Absolutely nothing is described, what type of vpn it is, what the firewall rules are, etc..
