It is important to change the MAC addresses for eth1.7 and eth1.8 to be different from eth1’s
one, otherwise - depending on the VDSL net disturbances can occur after forced disconnection.
For the new NIC Internet access must be possible, just as for the first NIC. These additional
settings are necessary:
PF_INPUT_1='IP_NET_1 ACCEPT'
PF_INPUT_2='IP_NET_2 ACCEPT'
PF_INPUT_3='any 224.0.0.0/4 ACCEPT'
[...]
PF_FORWARD_3='any 224.0.0.0/4 ACCEPT'
PF_FORWARD_5='IP_NET_1 ACCEPT'
PF_FORWARD_6='IP_NET_2 ACCEPT'
[...]
PF_POSTROUTING_1='IP_NET_1 MASQUERADE'
PF_POSTROUTING_2='IP_NET_2 MASQUERADE'
For working dynamic DHCP addressing at the new IPTV NIC and to access the set-top
box by its name, the following settings in dns_dhcp.txt are required:
HOST_10_NAME='igmp'
HOST_10_IP4='192.168.3.1'
HOST_11_NAME='iptv'
HOST_11_IP4='192.168.3.4'
HOST_11_MAC='00:D0:E0:93:49:34' # MAC Adr T-Home X300T
[...]
DHCP_RANGE_2_NET='IP_NET_2'
DNSDHCP_RANGE_2_START='192.168.3.10'
DNSDHCP_RANGE_2_END='192.168.3.20'
DNSDHCP_RANGE_2_DNS_SERVER1=''
DNSDHCP_RANGE_2_DNS_SERVER2=''
DNSDHCP_RANGE_2_NTP_SERVER=''
DNSDHCP_RANGE_2_GATEWAY=''
After configuring the new NIC it is suggested to connect it to a PC to see if Internet access
is possible over it. In case of success the new second NIC should be configured correctly.
IGMP Functions
When booting the fli4l router the parameters of the config file proxy.txt are written to the file
/etc/igmpproxy.conf, which is read when starting igmpproxy.
In contrast to earlier versions of opt_igmp the IGMP proxy is started at boot and then runs
as long as a physical Internet connection is available. The IGMP proxy is not affected by a
forced disconnetion after 24 hour or manual connect or disconnect of Internet traffic.
IGMP Configuration
OPT_IGMPPROXY ’yes’ activates the IGMP proxy package while ’no’ deactivates it com-
pletely.
