Problem with PING and Tracerout

Hey, folks, I have a problem with ping and traceroute from the firewall. I have made a VPN to the main exchange and it works ok. The firewall is connected to the L3 switch from which the WAN connection goes to the provider. From the switch, I can ping my host address on the other side but the traceroute doesn't work. While with the firewall I can't ping the remote host address and the traceroute doesn't work
