Sophos UTM 9.406-3 released

Sophos released 9.407-3 today, there is a new feature for DHCP MTU issue in confd, you can fix it with this:

Login as loginuser then root in ssh shell:

cc 
RAW 
lock_override 
OBJS 
interface 
ethernet (or cable, or other type) 
REF_ (Tap TAB two times - then you can see the interface list. Mine is called "REF_IntCabExternaWan[WAN,interface,ethernet]"
(You will get a look like this:)

'additional_addresses' => [],
'bandwidth' => 0,
'comment' => 'Added by installation wizard',
'inbandwidth' => 100000000,
'itfhw' => 'REF_ItfEthEth1',
'link' => 1,
'mtu' => 576,
'mtu_auto_discovery' => 1,
'name' => 'WAN',
'outbandwidth' => 20000000,
'primary_address' => 'REF_ItfPri000024',
'proxyarp' => 0,
'proxyndp' => 0,
'status' => 1
}

Then write:

mtu_auto_discovery=0 
w  (write the changes) 

Now go into Webadmin and find the WAN link, change the MTU under Advanced to 1500 and voila! :-)

This has solved the MTU issue for me and it appears back to normal.

FINALLY that took WAY too long for a fix.
