Hi,
I'm setting up my 1st linux router/firewall for my office. I'm
connecting to the net via ATT DSL using PPPoE. It's connected, but
something's wrong with my config (routing?) as I can't seem to ping
past my gateway.
I'm running a headless Opensuse 11.0 box,
uname -a
Linux router 2.6.25.18-0.2-default #1 SMP 2008-10-21 16:30:26 +0200
i686 i686 i386 GNU/Linux
pppd --version
pppd version 2.4.4
ATT have allocated a Static block x.x.x.144/29 to me.
>From the info I've been able to find online, I've set up ppp config as follows,
/etc/ppp/peers/att

Checking with Ping, I can
ping to my self,
ping -c 1 x.x.x.150
PING x.x.x.150 (x.x.x.150) 56(84) bytes of data.
64 bytes from x.x.x.150: icmp_seq=1 ttl=64 time=0.027 ms
and to my gateway,
ping -c 1 99.164.169.50
PING 99.164.169.50 (99.164.169.50) 56(84) bytes of data.
64 bytes from 99.164.169.50: icmp_seq=1 ttl=255 time=11.9 ms
but can NOT get anywhere past that,
# TO EXT DNS
ping -c 1 192.150.18.101
connect: Network is unreachable
I'm guessing that I've gotten something wrong in the routing. Here
the current table,
netstat -r

Any idea as to what's missing/wrong with my config that's preventing
ping/access past the gateway?
