Thanks everyone for pointing me in the right direction. This should all work its way out now. Mark

Starting with v197, systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet devices. jessie has udev v215. jessie-backports has v230. Jessie still has the old persistent naming scheme using /lib/udev/rules.d/75-persistent-net-generator.rules and /etc/udev/rules.d/70-persistent-net.rules by default, and the new predictable naming scheme is disabled (net.ifnames=0). The new predictable naming scheme has been enabled by default only since Stretch. So the behaviour described by the OP is a bit surprising. Mark, could you elaborate ?

Starting with v197, systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet devices. jessie has udev v215. jessie-backports has v230. -- Brian.
RE: Specifying multiple NICs
Toss something like this for each interface into
/etc/udev/rules.d/10-interface-names.rules
SUBSYSTEM=="net", ACTION=="add",ATTR{address}=="00:25:90:80:2e:a4", NAME="1gig1"
Replace the mac address with the one your interface has.

Subject: Specifying multiple NICs
I'm setting up a "just in case" replacement mailserver for my domain and my
local network. I'm using Debian Jessie, because the latest instructions for
setting the mailserver (qmail) are written for Jessie. The mailserver has 2
NICs (one for local network, and one for Internet).
In the past, I referred to each NIC as eth0, eth1,. but now, these names
are not permanent, and the designation can change on boot. I looked at the
"Network Coinfiguration" document which didn't have a solution. So, either how
do I make the names for the NICs permanent or what do I use fot the names of
the NICs?
Thanks,
Mark
