Surely that's plain wrong. 127.0.0.1 isn't your gateway - either with eth0 or ppp0.

Sure :-) But I still think it's a problem.
You have:
In my configuration, lo is:
> 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
See the difference? Only traffic to 127.*.*.* gets routed through the loopback interface.
Now, in fact, it's even funnier than this. After I disconnected gprs connection, just a few minutes ago, I restarted net by running netenv to change all the settings again. Now my /etc/network/interfaces is...
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# automatically added when upgrading auto eth0
Maybe I wasn't paying attention, but if eth0 is on a PC Card rather than a fixed connection, it shouldn't be "auto". Probably not relevant to this problem, though.
iface eth0 inet static address 150.217.140.158 netmask 255.255.255.0 gateway 150.217.140.1 network 150.217.140.0 broadcast 150.217.140.255
I would have thought this says your interface is 150.217.140.158 and any traffic to 150.217.140.* should be routed to the gateway at 150.217.140.1. You can't get to the internet from there :-) If you want _that_ to be a gateway, the netmask should be 0.0.0.0.
so, I believe, I should have the lo on again, but when I do route -n I get
I think setting "gateway", above, dropped the default gateway on lo (which I still say you don't want) and set it on eth0.
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

Try dropping the first route there. If 150.217.140.1 is _really_ a valid gateway, it's all you should need. However, it's acting like 150.217.140.1 is not a gateway to the outer world.
and I seem to get only to my domain, not outside. Ifconfig says
eth0 Link encap:Ethernet HWaddr 00:08:02:02:AC:9F

so, both eth0 and lo are actually up, but lo has disappeared in the route table. And although the gateway and dns (resolv.conf is ok) are on the right values, I get just as far as my work group....I'm getting confused....what am I doing wrong?
