Hello,
I have installed openwrt 2.4 for my linksys wrt54gl. I am a newbie with routers, but i have read a lot of thing about how to configure this ruter with openwrt.
I have succeeded to connect the ruter to my ISP, with pppoe. I have increased the TTL, because the ISP delivered the packages with TTL = 1.
I have build an interface for wireless connection, my laptop connects to the wireless and everything is fine. I can connect with ssh to 192.168.1.1, but the ruter does not send my internet packages.

ping google.ro - does not work, and i have no internet conectivity.
Even i can comunicate with the ruter, and the ruter has internet connection, i can not get internet packages.

I don't know if i have to add some new routs or something.
Can anybody help me please ?
Thanks

first of all,
can you ping google from the router, by logging into it using ssh ?
how did you make sure router accesses the internet ?
how did you configure ur wan port....?
coudl you post configs .....i never used pppoe but someone will help you ?

Hello,
I can login to ruter with ssh root@192.168.1.1, and from there i can ping some website.

I have configured the pppoe with this commands:
uci set network.wan.proto=pppoe
uci set network.wan.username=<pppoe_psername>
uci set network.wan.password=<pppoe_password>
uci commit network
ifup wan

I have configured the wireless connection using:
config wifi-device    wl0
    option type         broadcom
    option channel      5

config wifi-iface
    option device       wl0
    option network  lan
    option mode         ap
    option ssid         OpenWrt
    option encryption   none

I have changed the ttl using:
iptables -t mangle -A PREROUTING -j TTL --ttl-set 64
iptables -t mangle -A POSTROUTING -j TTL --ttl-set 64

Is there a probem with my wireless config ? I want to use the wifi for my notebook and other wireless devices.
I repeat myself: even if the router has internet connection (ping ... works), i can not do the same on my notebook. And my notebook is connected to the router, because i can connect with ssh to it.
Thanks

From what you said,
"I repeat myself: even if the router has internet connection (ping ... works), i can not do the same on my notebook. And my notebook is connected to the router, because i can connect with ssh to it."

I think your bridging has some problems....the router does not know how to
forward packets from wan to your lan..and vise versa
..can you post your network config too...

I have resolved the problem.
I was using:
iptables -t mangle -A PREROUTING -i ppp0 -j TTL --ttl-set 64;
iptables -t mangle -A POSTROUTING -o ppp0 -j TTL --ttl-set 64;
but at the second comand i used -i instead of -o, so no packages for my wireless

But now everything works fine. Thanks.
