ADSL – changing the modemTonight my modem was changed from an NEC to a Nokia M10. In the process, my firewall went from having a public address (e.g. 18.104.22.168) 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 problemI’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.
The implicationsThe 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.
11 March 10:03pmI’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.
