Speedtouch 546 as bridge under openSuse 10.3

glumetu · 05-06-2008, 01:27 AM

Hello everybody,

I apologize if this has been posted previously, I did search but nothing similar came up.

I cannot set-up my internet connection - here's some background data on my set-up:

ADSL modem: Speedtouch 546v6, DHCP
OS: OpenSuse 10.3
Mode: bridge (I want to put a wireless access point later on)

I have gotten to the point where everything is set-up like this:

Code:

# ifconfig

          inet addr:192.168.0.63  Bcast:192.168.0.255  Mask:255.255.255.0

Now I understand that my default gateway should be defined with the interface 'ppp0', not 'eth0' as you can see above.

Right now I'm a bit lost and I need your help - I suspect it may be something very simple - I just don't know what to do to change the default gateway's interface to ppp0.

I did understand that I need first to tell the system, at boot, not to create a default gateway to eth0, because I can't change it afterwards.

Therefore I created a /etc/sysconfig/network/ifcfg-ppp0 file with this configuration:

Code:

STARTMODE=auto
IFPLUGD_PRIORITY=
BOOTPROTO=dhcp
IPADDR=192.168.1.65
NETMASK=255.255.255.0
PREFIXLEN=
BROADCAST=
REMOTE_IPADDR=
LABEL=
SCOPE=
IP_OPTIONS=
INTERFACETYPE=
MTU=1492
LLADDR=
LINK_OPTIONS=
ETHTOOL_OPTIONS=
RUN_POLL_TCPIP=
USERCONTROL=
 
NAME=
UNIQUE=
_nm_name=
 
NM_CONTROLLED=no
 
BRIDGE='yes'
BRIDGE_PORTS='eth0'
BRIDGE_AGEINGTIME='300'
BRIDGE_FORWARDDELAY='0'
BRIDGE_HELLOTIME='2'
BRIDGE_MAXAGE='20'
BRIDGE_PATHCOSTS='19'
BRIDGE_PORTPRIORITIES=''
BRIDGE_PRIORITY=''
BRIDGE_STP='on'

this didn't really help at all

Many thanks for pointing in the right direction!

regards,
glu

Here's a pointer......document everything you do once you get this up and running.

I already am

Try this command

Code:

route add -net 192.168.0.0/24 gw 89.120.xxx.xxx dev ppp0

thanks a lot lsteacke, I have solved it an hour ago already, it was actually my DHCP client which was overwriting the default gateway, so I just shut it down, deleted my own config files (stupid anyway), I modified in /etc/systconfig/network/ifcfg-eth0 the BOOTPROT0 to 'static', re-ran pppoe-setup with the already default values, then pppoe-start... and I was in!

woo-hoo!
