Aside from the global firewall limits it is also possible to set the limit specific to the forwarding firewall in the Forwarding Settings (CONFIGURATION > Configuration Tree > Box > Virtual Servers > your virtual server > Assigned Services > Firewall). After changing these settings a Firmware Restart (CONTROL > Box) is required.
