On F19 how do I create persistent rules for ethernet interfaces?

cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x14e4:0x1693 (tg3) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1d: 72:05:4a:68", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# USB device 0x0bda:0x8150 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:e0:4c: 03:07:ba", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

But they are switched
:
 ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.10.xxx.xxx  netmask 255.255.255.0  broadcast 10.10.11.255
        inet6 fe80::2e0:4cff:fe03:7ba  prefixlen 64  scopeid 0x20<link>
        ether 00:e0:4c:03:07:ba  txqueuelen 1000  (Ethernet)
       .............................

eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 24.xxx.xxx.xxx  netmask 255.255.240.0  broadcast 24.xxx.xxx.xxx
        inet6 fe80::21d:72ff:fe05:4a68  prefixlen 64  scopeid 0x20<link>
        ether 00:1d:72:05:4a:68  txqueuelen 1000  (Ethernet)

You can't give KERNEL device "eth*" the NAME "eth"-something. Won't work. Or, at least, won't work reliably.

What does work reliably is giving KERNEL device "eth*" the NAME "other"- something.

If one of your ports in a WAN port, and the other one is a LAN port, why don't you name them wan0 and lan0? The rules that I have:

… KERNEL=="eth*", NAME="wan0"

and

… KERNEL=="eth*", NAME="lan0"

That worked just as well for my purposes, and actually makes more sense.
