(OT?) Anyone wanna address my ISP's issues? [CIDR/BGP question]

[OT Warning]  Not related to FBSD, other than the use of
ping(8), which is working as expected, apart from the fact
that the network *isn't*.

If anyone cares to give an opinion, TIA!

I'm trying to get a land-based (DSL) solution to my
rather remote office.  Found a provider, they (supposedly)
made arrangements with the local telco, sent me the DSL
modem, etc.  I set it up as instructed, but we're not
getting TCP/IP here on it.  Hours and hours of frustrating
hold music on the telephone, WWW-chat sessions that get
nowhere, etc.  The modem "sync" is fine, but, as one tech
put it, "sync but no surf".  It's been this way for >
2 weeks.

The DSL modem's outside (static) IP is n.n.n.70, the gw
is n.n.n.69, and the mask is 255.255.255.252.  From
inside, I can ping .70, but not .69 (and, needless to say,
nothing else, either).  From the outside, it's the
other way 'round.  Traceroute (from outside) shows different
endpoints for the two addresses (that is, the last hop 
before .69 is one router, and, when looking for .70, it's
another router (but not the one that leads to .69)).

If I did my CIDR homework correctly, the net is n.n.n.68/30.
Using "BGPlay" (http://bgplay.routeviews.org/bgplay/), I get
the message: "The selected data sources have no information on
prefix n.n.n.68/30.  Please check that this prefix is globally
announced."

My question: shouldn't it be 'announced', if the ISP intends
to route me TCP/IP traffic?  I apologize for my ignorance, 
but BGP isn't something I figured to need to know at this 
point in my life (although, it doesn't hurt to learn, usually)....

Thanks again,


Kevin Kinsey
