[Openvpn-users] Problems with ARP using tun devices between two LANs

Hello,

I'm experiencing this kind of messages when the communication is
setup:

tap20: promiscuous mode enabled
arp: 00:bd:e6:26:01:00 is using my IP address 10.111.0.3!
arp: 163.117.140.181 is on xl0 but got reply from 00:bd:e6:26:01:00 on tap20
arp: 163.117.140.2 is on xl0 but got reply from 00:bd:e6:26:01:00 on tap20
arp: 163.117.140.72 is on xl0 but got reply from 00:bd:e6:26:01:00 on tap20
arp: 00:bd:e6:26:01:00 is using my IP address 10.111.0.3!
arp: 00:bd:e6:26:01:00 is using my IP address 10.111.0.3!
arp: 00:bd:e6:26:01:00 is using my IP address 10.111.0.3!
arp: 00:bd:e6:26:01:00 is using my IP address 10.111.0.3!
arp: 00:bd:e6:26:01:00 is using my IP address 10.111.0.3!
-- loop (0) 00.bd.e6.26.01.00 to xl0 from tap20 (active)
arp: 10.111.0.1 moved from 00:bd:e6:26:01:00 to 52:54:ab:dd:22:98 on tap20
arp: 10.111.0.2 moved from 00:bd:e6:26:01:00 to 00:50:fc:2e:46:f2 on tap20


The effect is that my client network (163.117.140.0) gets stalled.
I've tried to find out what machine is "00:bd:e6:26:01:00", without no
success at all. I guess it might be the remote interface MAC address.
Why is this happening ? It looks as if the openVPN server was doing
proxy ARP of all the queries, getting my local network blocked.

Thanks for your help.
