#1195 confirmed enhancement

DynDNS behind NAT doesn't work

Reported by: michael.nicolai@… Owned by:

Component: fon-plugin-ddns Version: N/A
Severity: major
Cc: Hardware: both

Description

I was wondering if besides the 2 options of "IP Address to Send": -let provider detect -use fonera internet ip (which is the ip the fonera gets on it's wan port I assume)

if there is an option to get the output from a website like in the ddns-scripts package for openwrt e.g.

(option ip_url "http://automation.whatismyip.com/n09230945.asp")

  • Severity changed from unknown to major
  • Status changed from new to confirmed
  • Version changed from 2.3.7.0 beta3 to N/A

I've considered offering this option, but it's a bit tricky to get it right.

In particular:

  1. A lot of these services are offered by DDNS providers, which are of course intended for people that also use that provider for their DDNS. We can't really pick one of those to use for all DDNS lookups and having a separate ip_url for each DDNS provider is probably too much work to implement and maintain.
  2. When using a third-party site, it is always uncertain if the service will remain available in the future.
  3. A lot of third-party sites are unclear on their exact usage conditions. A lot are really intended for manual use by persons, not automatically by thousands of Foneras doing a lookup every 10 minutes.

The link you provided seems promising, I even found some usage conditions here: http://www.whatismyip.com/faq/automation.asp (though I couldn't find this link anywhere through the main site, instead I had to Google it...). I'm still not sure if this would really work, though.

In any case, you can start using this feature now by setting the "ip_source" option to "web" (in addition to setting the "ip_url" option as you suggested above). I haven't tested this, but I think this should work out of the box.

Thanks for the reply, been using a modified openwrt version for my 2.0n until recently, snatched from "http://www.erriko.it/sistemi-operativi/openwrt-sistemi-operativi/nuovo-firmware-ufficiale-openwrt-per-fonera-2-0n-update/"

works like a charm by the way, but getting openvpn working on it proved to much for me, although socks5 is the next best thing after replacing dropbear by openssh, another neat thing I got working on it was murmur (a mumble server, sort of like teamspeak), could be fun as a plugin I think ;)

Anyway switched back to Alpaca, I'll let you know if the dyndns thing works out, using http://myip.dnsdynamic.com/ atm
