With ASL 5.206,
On my INT interface, I have ASL's DHCP Server enabled, with:
range start: 192.168.11.190
range end: 192.168.11.210

and Static Mappings for 3 devices at:
00:04:76:F7:4C:E9 192.168.11.197 PC
00:10:83:0C:A8:1B 192.168.11.198 JetDirect
00:01:1D:10:5F:6B 192.168.11.200 VOIP device

My notebook
00:0F:1F:16:B5:E9
gets the .197 IP!

e.g.
Today, PC was off, notebook was on. PC was booted, and was assigned .197 IP via DHCP (as is expected per the static map). When PC was unable to reliably access the internet, I eventually discovered both it and the notebook were using .197!

Assigning the notebook a static DHCP mapping of .210 works.

I'm using a 10/100 HUB, not a switch, btw. (not that this should make much difference.)

Questions:
1. Should the static mappings be OUTSIDE of the DHCP "Range".
2. If not, what the heck is going on?

I do not have any other DHCP servers on the network. The VOIP adapter only has the WAN side connected.
Regardless, in the "Leasing Table", ASL shows the MAC of the notebook assigned to .197 (twice actually, both with the same time, but different expiration times.) It does not show leases for any of the Static Mapped IPs or MACs.

Also, there is an entry in the Leasing Table for MAC FF:FF:FF:FF:FF:FF with IP 192.168.11.207
Why?
Pinging that IP does not get a response, fwiw.

/var/sec/chroot-dhcps/var/state/dhcp/dhcpd.leases is consistent with the "Leasing Table", although it does have some older entries as well. It does not have any entries for ANY of the reserved IPs/MACs.

Thanks,
Barry

You are right Barry,

the static addresses should be outside the range of the dhcp leases.

OK, thanks.
ISTM this should be mentioned in the builtin help, if not on the page itself, as it is not intuitive.

Thanks,
Barry

This still isn't mentioned in the online help in 5.210.

Barry,
before I answer part of you question. I made the same mistake as you did and couldn't understand it. I think the Astaro DHCP implementation has a minor bug in that it does allocate or record the same IP address to the same MAC address with different times and it can be within in minutes of the original request.

Stretching my brain to when I worked on DHCP deployment I remember the requirement was always to have your static addresses outside your auto assigned address range. I think Astaro assume that we know/remember this information and haven't included it in the help file.
