Hello there. I seperated lan from wifi. first i thought that everything worked fine but then i tried to connect through wlan. i mentioned that my pc can connect to the network but it wont get an ip nor can it ping the router or any other address. i have read the other posts in this forum about that problem but they didnt help me much.

Now i come straight to my settings:

Linksys WRT54GS (lan=vlan0, wan=vlan1, wifi=eth1)

NVRAM: (i post everything that i think can be necessary)

vlan0ports=1 2 3 4 5*
wl0_mode=ap

lan_ipaddr=192.168.1.1
lan_netmask=255.255.255.0
lan_ifname=vlan0
lan_proto=static

wifi_ipaddr=192.168.2.1
wifi_netmask=255.255.255.0
wifi_ifname=eth1
wifi_proto=dhcp

wan_proto=pppoe
wan_ifname=ppp0

dnsmasq.conf:

domain-needed
bogus-priv
filterwin2k
localise-queries

except-interface=vlan1

dhcp-authoritative
dhcp-range=eth1,192.168.2.100,192.168.2.250,255.255.255.0,12h
dhcp-option=eth1,3,192.168.2.1
dhcp-option=eth1,6,192.168.2.1
dhcp-leasefile=/tmp/dhcp.leases

read-ethers

I just modified nvram and dnsmasq.conf. have i done something wrong? did i forget something?

best regards

Hi,

wifi_proto should also be static. wifi_proto=dhcp would meen that the wifi interface it self get his ip-address by an external dhcp server. But you defined the ip by hand in wifi_ipaddr, so wifi_proto=static have to use.
the other nvram variables are good.

In the standart config of openWRT dnsmasq don´t use the /etc/dnsmasq.conf  file,  but will be configured by the /etc/init.d/S50dnsmasq  startup-script. So a change in dnsmasq.conf will not effect to the funktionality.
Change the S50dnsmasq, that dnsmasq will be start without any arguments.
Than you can use /etc/dnsmasq.conf to configure dnsmasq.

Note for 2 subnets you have  to define 2 dhcp-ranges.
dhcp-range=vlan0,192.168.1.100,192.168.1.250,255.255.255.0,12h
dhcp-range=eth1,192.168.2.100,192.168.2.250,255.255.255.0,12h
for more details look at this thread: http://forum.openwrt.org/viewtopic.php?id=2235

thanks for the quick reply.

but 2 questions

1. how can i change S50dnsmasq? can you post some code? i am too much a newbie

2. why do i have to define a dhcp range for lan. i dont use dhcp for lan and dont want dhcp working for lan.

P.S.:

how can i write my configs in notepad and then copy them from my desktop to the router? with cp? but how to copy from network source?
