But when I installed two more NIC's for our LAN I see some errors. I have a real IP-address on LAN outside interface, using ipnat for our traffic. I see: /kernel: arp: 00:01:02:8a:72:d8 is using my IP address XX.XXX.XXX.XX (XX = outside IP-address) The mac-address is the outside interface of the DMZ-bridge. Both outside interfaces are connected to the same switch. The network setup: [Internet] | | [ Switch ]----[Outside interface DMZ; No Ip-address assign] | | [ Outside interface LAN] Why does my bridge think it have an IP-address? The setup is working, so I don´t know why I get this errors. System: FreeBSD 4.5-STABLE-20020502 rc.conf: ipfilter_enable="YES" ipfilter_flags="" ipnat_enable="YES" gateway_enable="YES" Best regards, Johan Björk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
