I'm being stupid (linux)

I'm sure there is something really simple I've missed.
I have a origo asr-8100 ethernet modem/router.
(I am aware of the security problem with this router, and have
fixed it)

It's currently working fine as a gateway.
I'd like to turn on "ppp half bridge" and get my server onto the
net properly, so it can accept connections easily.
I have a static IP from plusnet. (call it 2.2.2.2)
The router is on IP 10.0.0.2

Setting up the router and doing
route add 10.0.0.2 eth0
route add default gw 10.0.0.2

works with the modem in its default mode, and outbound connections
just seem to work.

Now, why doesn't
ifconfig eth0 2.2.2.2
(with "ppp half bridge") just work?

I shouldn't need dchp or anything, as the IP is static...
Confused.
Any help would be welcomed.

It would appear that the Conexant based modems _require_ the use of
DHCP when using PPP half bridge (I am using an Dabs Value, aka Origo,
in this mode). I don't see any reason why with a static IP, but that
seems to be the way it works.

I've also found the router very fussy about the order things happen,
otherwise it drops the ADSL connection. For example, if my Linux machine
is rebooted, or DHCP is attempted before the router has authenticated,
the connection is dropped.

The main IP address for the interface is allocated by the router using
DHCP (which has a rediculously low renewal time, despite being configured
as static). I have an alias "eth0:0" with the IP address 10.0.0.1, so
I can reach the router on 10.0.0.2, with the client considered to be a
connection from the LAN.

To keep things ticking over, I have a script that pulls back the router
syslog, and if the connection has been lost, it attempts to reconnect
as follows. The router is set to reboot, and the interfaces taken down
for 60 seconds. This allows time for the router to reboot, connect and
authentcate before the Linux DHCP client starts up. This keeps it happy.

"It works with windows, ship it".
Oh well.
As I seem to have no dchp client software, I suspect I'll be downloading it tomorrow.
Thanks.

Another interesting feature of this router seems to be that if you use mozilla as your browser
(I'm using a 4 week old build) you can't actually see anything other than the username/password
prompt on the router login screen.
Not to mention the unpassworded WAN visible telnet interface which lets anyone turn
off your internet.

I had one of these working no probs with Linux.
as to the router login you need to change the port. then as long as no one
knows it you are Ok or use DMZ.
as to putting your server on the web why dont you forward the reqd ports
this much safer personally I just forward port80 for
my webmail server and thats it.

What Linux build do you have that doesnt have DHCP as part of the standard
build.?

PS If you want a decent gateway look at e-smith

To get to the other setup bits in an Origo, browse to
http://10.0.0.2/doc/advance.htm (assuming your router is 10.0.0.2).
Should work in any browser.

Does the router alow you to alter the dhcp address range ,cisco and my
draytek do ,then add your server in the excluded range.

I do this so I can connect my laptop without setting the IP up but static
computers are not on the dhcp.

You can set a password on the telnet interface, I don't think you can change
the port, though you can add rules to forward it to nowhere.

Because I want to be able to run random stuff without fiddling with the
router.
There are no servers running as root on the box, all as untrusted users.

Slackware (7?) with bits added as I need them.

Any chance of mailing me the various config files/scripts, so I can at least
get an idea of what a working config looks like?

Many thanks for the help.
