No internet from a dmz server

[Kordian]

Hello,

Here is my story:

On fortigate 100d I have a dmz configured and (I thought) running. In dmz there is already one server installed. From this server I can ping anything outside. Internal ip is 171.30.1.9 This dmz physical has an external ip of 216.8.110.161. To this physical port also another external ip is added as secondary ip address, namely 216.8.110.162.

I installed another server in this dmz. Configured it with 171.30.1.10. This one can ping the default gateway (171.30.1.1), but cannot ping anything outside. The traffic from outside to this new server is working as desired.

The route -n command of this server returns this:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface 0.0.0.0         171.30.1.1      0.0.0.0         UG    0      0        0 eno2 171.30.1.0      0.0.0.0         255.255.255.0   U     0      0        0 eno2

The policies are set the same for both dmz servers.

What am I doing wrong?

Thank you in advance!
