hi again!
sorry, my schema wasn't really clear....

I have only one wlan physical interface -> wan_1 wan_2 and wan_3 will be virtual interfaces.

In fact, lan->wan is ok, I have a connection on it.
I tried to put a dmz, but no luck : no internet on it.

Here's what I have :
Code:
#### VLAN configuration 
config switch eth0
	#option vlan0	"1 2 3 4 5*"
	#option vlan1	"0 5"
	option vlan0	"1 2 3 5*"
	option vlan1	"0 5"
	option vlan2	"4 5"


#### Loopback configuration
config interface loopback
	option ifname	"lo"
	option proto	static
	option ipaddr	127.0.0.1
	option netmask	255.0.0.0


#### LAN configuration
config interface lan
	option type 	bridge
	option ifname	"eth0.0"
	option proto	static
	option ipaddr	192.168.1.1
	option netmask	255.255.255.0

#### WAN configuration
config interface	wan
	option type	bridge
	option ifname	"eth0.1"
	option proto	dhcp
	
#### DMZ configuration
config interface	dmz
	option type	bridge
	option ifname	"eth0.2"
	option proto	static
	option ipaddr	10.10.0.1
	option netmask	255.255.255.0
Code:
config dhcp
	option interface	lan
	option start 	100
	option limit	150
	option leasetime	12h

config dhcp
	option interface	dmz
	option start		10
	option limit		15
	option leasetime	12h

config dhcp
	option interface	wan
	option ignore	1
My computer in dmz has an ip, in correct range.

(final aim is that computers connected to my asus will have ISP IPs.)

MONIT interface is to access asus, as I want it to be transparent and to be accessed only by this port. it's a physical ethernet port. but for now, it's a bonus, I want the rest to work first ^^'

Regards
