DHCP - Not setting Subnet, issues with PXE Boot

Not applicable

We are having an issue with our new Palo Alto 2050.

We are using the DHCP server on the 2050 in conjunction with a PXE to iSCSI system.

Using a different firewall/router with integrated DHCP server - the system works fine.

With the 2050 - it doesn't.

We took a packet sniff of the failed DHCP 'conversation' and it seems from our packet trace that the 2050 is not setting the subnet (it comes down as which the vendors of the PXE server software think may be causing the issue.

There is also another 'option' for DHCP which does not get sent down which is Option3: Router.

We are on PANOS 3.02.

We need the ability to boot PXE clients from SAN, so it will become quite a problem for us if we can't get this working.
