Hi,
I have upgraded my astaro box "software appliance " to UTM 9.003-16
but it seem that it make very strange DHCP issue in my network, here is the details:
-My network consist of two vlan , one for voip "vlan 2" , the other for Data "vlan 3" "native vlan"
-My UTM 9 box belong to Data vlan , so UTM-9 box does not involve in voip traffic in any way.
-All my network devices including IPphones,PCs and UTM-9 box are connecting to layer 3 switch which include IPPBX. kindly find the attached topology of the network.
-By the way, UTM-9 box acting as DHCP server for Data network.
layer 3 switch acting as DHCP server for voip network.
-Before upgrading everything was working normally ASTARO provide DHCP service to Data vlan, and the layer 3 switch provide DHCP services to voip vlan.
-After upgrading, it seem that there is some DHCP services messing in voip vlan , it seem that UTM9 trying to provide dhcp to voip vlan, and then there is some IPphones can not obtain the correct voip vlan ip address and this result in failing in bootup.
-When I disconnect UTM-9 from the network all thing work normally and all ip phone obtained the right ip address from voip pool.
-Kindly find the attached UTM-9 DHCP log " you will see mac address like 00:04:f2:aa:68:7e which belong to IP phone.
-Kindly find the attached DHCP server debug output of the layer 3 switch.
Thanks,
Mostafa Aly
