Correct tap settings for three card

[AloPancho]

Hi!:

This is my first post, I hope any of you cuold see my problem:

I have a computer with three ethernet card (connected by wires crossed with other computers) and a USB 3G modem, two ethernet cards should be able to send and receive information from the Internet. but I have problems because they are disconnected without notice, here I leave the file /etc/conf.d/net

I have tried various tap settings, I would like to know if what I did right and what may be my problem. (for the post I put the 'xx')

# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
tuntap_tap0="tap"
tuntap_tap1="tap"
config_tap0=( "0.0.0.0" )
config_tap1=( "0.0.0.0" )
#config_eth0=( "204.213.xx.xx netmask 255.255.255.0 broadcast 204.213.xx.xx" )
config_eth0=( "null" )
config_eth1=( "null" )
#config_eth2=( "204.213.xx.xx netmask 255.255.255.0 broadcast 204.213.xx.xx" )
bridge_br0="eth1 tap0"
bridge_br1="eth0 tap1"
rc_need_br0="net.eth1 net.tap0"
rc_need_br1="net.eth0 net.tap1"
config_br0=( "211.222.xx.xx netmask 255.255.255.0 broadcast 211.222.xx.xx" )
config_br1=( "204.213.xx.xx netmask 255.255.255.0 broadcast 204.213.xx.xx" )
