DHCP - DNS Suffix Search List has value "lan" in it / Cannot set DNS Suffix Search List

[MIchGree]

Hi,

We are configuring a brand new Fortigate 60E with the latest firmware V5.6.0 build 1449 (GA).

After running the Setup Wizard I connected a laptop and we are getting some VERY BIZARRE settings from DHCP.....  including a DNS Suffix Search List that just has a value of 'lan' in it.

This has stopped our Fortinet roll-out dead in its tracks as name resolution is not adding the correct DNS suffix.

e.g.

lscsv01

needs to be come

lscsv01.livingspace.local

NOT

lcssv01.lan

Has anyone come across this BUG ?  Or is it a setting we have missed ?  I can't see where to set the 'DNS Suffix Search List'......

Here is what we are getting on DHCP:
