I'm a bit confused.  Though for some reason you're obfuscating your IP#s 
(how do you expect us to help you if we can't check for errors 
ourselves?) it lloks as if you're trying to access the box both 
remotely and locally.

It looks as if locally you're getting through with an IP# beginning with 
an IP# in the range 192.168.0.0/16.  Those addresses are reserved for 
local use and are not available on the Internet at large (Internet 
routers won't route them).

What address are you using for access over your DSL link?  If it's the 
same address, then it won't work for the reason I stated in the last 
paragraph.  If it's a different address then I have a few more 
questions:

Do you have both addresses linked to the same ethernet port, or are you 
using two distinct ethernet ports?  If you have both addresses linked 
to the same ethernet port, then you're trying to use local and routable 
addresses on the same ethernet segment, and you may not be doing it 
right.  (Actually there is no "right" as you probably shouldn't be 
doing it this way, but it is doable.)

If you've got the addresses on different ethernet ports, or if you're 
using the same ethernet port but only for one IP# at a time, and you're 
sure you've properly rewired the local (to the system) network each 
time you've switched, and have also properly reconfigured the system 
each time you've switched...

Then it's most likely your ISP isn't allowing that port through their 
own firewall.  You can ask them to be sure, but it's unlikely that 
first level tech support will have any idea what you're asking about, 
and may very well give you the wrong answer.

Which is why it's probably not a DNS issue... though since you haven't 
shown us your zone file or told us your real IP#, we can't be sure.

Whether or not you run your own DNS is unimportant to the issue at hand.  
If checkdns.net indicates your DNS is okay, it probably is.

If you can get them to fix it, then do so, because...

This could be a problem, but only for you, and only locally, and only if 
you're using W2K/XP computers on the same routable network.

It really sounds like the ISP has blocked the port you're trying to 
connect through.
