[cobalt-users] [Qube3] dynamic DNS, DSL and Qube3 - how?

["Ingo Zitzmann" <i.zitzmann@xxxxxxx>]

Hi everybody,

I just received my Qube3 and I am trying to run it off my DSL line. 
I am using a dynamic DNS service to map my domain to the current IP. 
I am a little fuzzy on where I need to enter what. 

Do I need to run DNS on the Qube itself or is that done solely by the dyn. DNS?
I assume this messup is also the reason why I keep getting those emails of this type:
...
5.5.3 MX list for domain.net points back to relay.domain.net 
5.5.4 <user@xxxxxxxxxx>... Local configuration error 

Therefore I can neither send nor receive... :-(

Can somebody help me on how to set this thing up?

* eth0 is connected to my hub for internal use - currently I have the domain also defined for the IP that I have internally (same with the MX) - I guess that's 
wrong though
* eth1 ist connected to the DSL modem
* I set my dyn. DNS to point *.domain.net to my IP that I see for ppp0 via ifconfig as well as defining a FQDN www.domain.net as A record and a MX 
domain.net pointing to www.domain.net

Anybody done this? (I guess so)  Any good/bad experience with a (free) dyn. DNS provider?

Thanx a million.
Ingo.
