How to allow Traceroute from internal network?

Jui (Uwe Betz)
I just wanted to do a trace from an internal system using WS_PingPro and found that this doesn't work at all. The only machine I get an answer from is the Astaro Fw/Router itself.
So I opend my PacketFilter for ALL traffic, but it didn't help. Traces with the Traceroute-Tool on the firewall work just find, but why not from an internal Client? NAT shouldn't hjave anything to do with that or am I wrong?
With my SMC and a Netgear there were noe Problems like this. What do I have to configure to let internal machines Treceroute external machines?

    I have it enabled all the time. I have also Treceroute Forwarding enabled. 
    I get Timeouts on the route except the target.
