Hi, Alex!
You can make virtual NIC via netgraph. 1. ng_ether automatic attached to every physical NICs on load module. 2. connect ng_bridge to upper and lower hooks on ng_ether 3. create and connect ng_eiface to ng_bridge and you will get new NIC ngethX with its own MAC address and IP addrs too. 4. repeat 3 :) But, do not connect physical NICs to one ng_bridge! Example # 1. loading netgraph modules kldload ng_ether kldload ng_bridge kldload ng_eiface # 2. create and connect bridge to physical NIC ngctl mkpeer em0: bridge lower link0 ngctl connect em0: em0:lower upper link1 # we can set name for bridge, and replace em0:lower -> em0Bridge in ngctl calls ngctl name em0:lower em0Bridge # 3.1 create and connect first virtual NIC ngctl mkpeer em0:lower eiface link3 ether # 3.2 create and connect second virtual NIC ngctl mkpeer em0:lower eiface link4 ether # configure virtual NICs ifconfig ngeth0 link 00:11:22:33:44:01 ifconfig ngeth0 inet 192.168.1.254 netmask 255.255.255.0 ifconfig ngeth1 link 00:11:22:33:44:02 ifconfig ngeth1 inet 192.168.2.254 netmask 255.255.255.0 -- Rozhuk Ivan > -----Original Message----- > From: owner-freebsd-...@freebsd.org [mailto:owner-freebsd- > n...@freebsd.org] On Behalf Of Alex Zhang > Sent: Saturday, December 18, 2010 2:30 AM > To: freebsd-net@freebsd.org > Subject: Virtual Network Interface Card > > Hi all, > I just wonder that if there are virtual nic functionalities which > provides MAC address? > I need to run ISC DHCP Server on 4 different IP's within one sever, > however I have only 2 NICs connected to the server.
