Excuse for bad English.
In shortly:
I have em0 and em1 interfases on my router.
em0: xxx.xxx.xxx.2 (The real IP from xxx.xxx.xxx.0/28 IP range)
em1: 192.168.0.1 (192.168.0.0/24 my internal net IP range)
Internet<---->[em0<---->em1]<---->[Windows]
Router
1. On external interface of my router, i setup "proxy arp" use the
following commands:
#arp -s xxx.xxx.xxx.3 AAA.AAA.AAA.AAA pub
Where AAA.AAA.AAA.AAA is MAC on external interface of my router.
2. On internal host with run Windows 2000 AS (192.168.0.2) I add the
additional IP (xxx.xxx.xxx.3) from my real IP range.
In this case, windows host show the error message (like it):
Address conflict. Host with MAC AAA.AAA.AAA.AAA have a my IP. The local
interface will be disabled.
If I try setup real IP to Windows machine first, and "proxy arp" to my
router second all work properly.
