OPT_DHCP_CLIENT='yes'
DHCP_CLIENT_TYPE='dhcpcd'
DHCP_CLIENT_INTERFACES='IP_NET_3_DEV' # listen on interface eth1.8
DHCP_CLIENT_USEPEERDNS='no'
DHCP_CLIENT_HOSTNAME=''
As of fli4l V3.3 the interface can only defined by the value of IP_NET_x_DEV defined for the
interface in base.txt, here: IP_NET_3_DEV. Specifying eth1.8 is not possible anymore.
Optional:
If the NIC in use has problems with the MTU size it can be adapted with the parameter
DEV_MTU. Intel Pro/100 (e100) and a 3-Com card worked well during tests without changes,
but a 3Com ’3c59x’ was reported to need a MTU of 1496.
DEV_MTU_1='' # Adjust MTU size of NIC on VDSL-Modem
# Example: DEV_MTU_1='eth1 1496'
The config files base.txt and dns_dhcp.txt have to be changed as described in the next
chapter.
Configuration Of An Additional NIC For IPTV
In base.txt and dns_dhcp.txt the configuration has to be changed for VLAN and for the
second NIC.
Insert the second NIC for IPTV:
NET_DRV_N='2'
NET_DRV_1='via-rhine' # 1. NIC interface for LAN
NET_DRV_2='3c59x' # 2. NIC – here 3Com for IPTV SetTopBox
Now the address range for the second NIC has to be set. We will use 192.168.2.0/24 for the
LAN and 192.168.3.0/24 for the second NIC. Entries for the virtual NICs eth1.7 and eth1.8
are needed in addition:
IP_NET_N='4'
IP_NET_1='192.168.2.1/24' # home/office LAN
IP_NET_1_DEV='eth0'
IP_NET_2='192.168.3.1/24' # iptv LAN
IP_NET_2_DEV='eth2'
IP_NET_3='dhcp' # dhcp client - IP via dhclient
IP_NET_3_DEV='eth1.8'
IP_NET_3_MAC='00:40:63:da:cf:32' # new MAC (not the MAC of eth1)
IP_NET_4='dhcp' # eth1.7 connecting to the modem
IP_NET_4_DEV='eth1.7'
IP_NET_4_MAC='00:40:63:da:cf:33' # new MAC (not the MAC of eth1)
