Thank you all for the help, links, doc, and advices.
To make sure I am in the right track for me to have the devices in eth1 and
eth2 get an IP from my LAN which is connected to eth0 I do:
BRIDGE0=“eth0 eth1 eth2”
EXTIF="br0"
The end goal is to have access to the web interfaces of my phones and
devices behind the Astlinux router.
I can also enable dhcp on the ports and just map those ports to a iptables
rule to map the ports...
Any thoughts?
Thank you all for the help!
Thank You,
Fernando Fuentes
