ADSL – changing the modem

ADSL – changing the modem

Tonight my modem was changed from an NEC to a Nokia M10.  In the process, my
firewall went from having a public address (e.g. 210.55.210.87) to having a private
address (e.g. 192.168.0.59).  This makes it very difficult to provide http, telnet,
dns, mail, and other services.  I’m in the process of figuring more about this modem.

At present, all services provided by freebsddiary.cx are down.

The problem

I’ve just changed from an NEC ADSL modem to a Nokia M10 RDSL modem.  And I’m very
disappointed to see that the RDSL modem does NAT.  Mainly because my FreeBSD box no
longer has a public address.  I can’t yet see how to redirect requests from the M10
to my FreeBSD box.

I can configure the modem via an HTTP or telnet interface. 
There is an NAT setup.   I’ve managed to add a Pinhole entry to redirect external
port 80 to an internal IP address.  But browsing to the external address gets no
response.

I’m going to contact my ISP in the morning, but I have a feeling I’m not going to like
their answer.  I’ve found nothing on the web for this Nokia M10.

Any suggestions?

The implications

The implication of this modem swap is that none of my services are available outside
my own subnet.  That’s really [insert your favourate expletive here] annoying.  
I’ll be talking to my ISP today.

I’ve managed to get my www, telnet, DNS, and mail services back online.  I still
have FTP to restore.  But I can’t do that at present.  The M10 appears to allow
only eight pinhole entries (i.e. redirects) at a given time.  That is someone
limiting to say the least.

I also have dhis.org site to restore.  I have no doubt dhid
is confused about the external address.

My ISP has contacted me, but it was at a bad time for me; I was just about to go into
a meeting.  They were going to ring me back later that day, but they didn’t.

Quite a few people are finding this page and asking me for more information about the
Nokia M10.  If you have signed up with Telelcom New Zealand and have ADSL, you may be
interested in the ADSL mailing list.  This list is aimed at NZ broadband in general.
