Please help: Stuck on part 8 (no more internet)

[samirsky]

After following the instructions for step 8 changes to /etc/config/network (including lan/wan correction in step 9), I can no longer connect to the internet. When I "ping www.google.com", I get "ping: bad address 'www.google.com'". The "Air" light on the Asus is on (although dim).

When I undo the changes to /etc/config/network and wireless, I get internet connectivity again. I changed my home wireless router to 192.168.24.xxx to avoid conflicts. With this configuration I can access internet (ping google, wget from mightyohm.com, etc). When I make the changes in Steps 8/9, I no longer can access the outside world.

Please help!
Any help is appreciated.

Hello!!

Can you post your before and after (working and not-working) /etc/config/network and /etc/config/wireless files? Did you change /etc/config/firewall also?

No changes to firewall.
As of this documenting/testing/, home network is on 192.168.1.xxx

root@OpenWrt:~# ping http://www.mightyohm.com
ping: bad address 'www.mightyohm.com'

Do I need to change the 'config forwarding' in firewall? Note that in this configuration I am able to Telnet to the router with a direct RJ45 cable from my latop to the router, as well as via the serial interface (FTDI cable).

Any ideas on why the last config does not work is appreciated.

Thanks dddesign for your reply!
But I couldn't get that to work either.

After spending many hours trying different options/combinations, this is what I got to work:
network file:

Code: Select all

#### VLAN configuration
config switch eth0
        option vlan0    "1 2 3 4 5*"
        option vlan1    "0 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   192.168.2.1
        option netmask  255.255.255.0

#### WAN configuration
config interface wan
        option type     bridge
        option ifname   "eth0.1"
        option proto    dhcp

The trick for me is to have the router lan address on a different subnet than my home network (ok, I can kinda see how that might be needed), and making the wan "option type bridge". I must do BOTH. Either of the above changes alone don't work.

Is that right? I have seen no one else who needed to make the wan 'bridge'. That is the only way it seems to connect to my wifi network (by monitoring the "DHCP Active IP Table" on my home network wifi router). Is this bad? Could it mess up something?
