Dynamic DNS shouldn't actually require any specific configuration of your router necessarily... I use DynDNS.org - with comcast. Most routers support Dynamic DNS, and I tried that, but with Comcast, my IP only changes about once every 6 months - and my router would only report changes - meaning it wouldn't report every 30 days, and they would expire my account. I found that using their free client on my PC worked much, much better.
That of course just takes care of your IP routing - the next problem is what to do when trying to come in. If you can ping your DNS name and it matches your external IP (check www.myipaddress.com) - then what you're struggling with isn't the DNS portion, but the port forwarding. That needs to be set up through your router - and I've read of a lot of issues with FIOS, but since it's not available here, I can't speak to it much.
It's important to clarify where the issue is, where you're stuck, and what your end goal is - that'll help everyone help you.

ok - first try to ping your Dynamic DNS name - even from your home, this should tell you. Don't expect a reply, but it should at least resolve to the same IP address you see if you go to myipaddress.com.
If not, your problem is in your DynDNS setup. If it works, but your remote access to the Elk isn't working, the next test is to make sure that your router is forwarding the right ports.
Let us know which one and we can help further.

It may be worth trying a different port. I think the default DNS port is 80. I can't speak for an M1 but I have HomeSeer set up as a server with DynDNS on port 84. You would just address it as 'youraddress.whatever.com:84'. You need to be sure the port is forwarded to the correct address of your machine. I set up the PC to have a static address on my little network and the router forwards port 84 to that address.

FYI: Some ISPs block some port 80 traffic to prevent you from running a home server.

Yes DDNS is working correctly, you can also simply test this by going to network-tool.com and putting in your domain.
You need to figure out what the IP address for the device hosting the M1 I would assume it's the ethernet expander. You'll need to provide it a static IP address outside the HDCP pool of the router. Then you'll need the list of ports required. If port 80 is specified you'll probably need to change that 81 should suffice.
Might recheck that I have no clue but I would be surprised if you didn't need 2 ports. I'm thinking TCP 2601 maybe the control port and 80 is the interface.
If you so can forward external port 81 to internal port 80.
Or must you specify a port every time you connect on the local network?

If you could be just be 'a little' more specific as to the error messages, that would help a lot. Screen shots of the messages, also would be very helpful. Not to be critical, but when ' it now says that something else is already connected', I have no real idea what you are talking about.

What it basically sounds like is that the built-in web server is accessible - it's getting the stuff off Port 80 - but that seems to be what loads the java applet, which then talks to the M1 via the secure port, which by default is 2601. If you haven't changed that, test connectivity to that - preferably from the outside, but attempting a telnet - so, from a command prompt, you can try typing "telnet mym1.dyndns.org 2601" (or whatevever dns name you chose).
It probably won't tell you anything useful, but if it connects, you'll get a blank window you can type in (it won't echo anything back). If that works, then it's likely with your browser or PC.
Is this a standard PC, Windows XP, etc? I know that my Mac on Safari doesn't seem to connect, but I've put about 20 seconds into troubleshooting - so I don't know if that's fixable. PC's with standard security IE seem to work just fine.
