|DBISam Server Ports Are Often Closed|
|Sun, Dec 8 2013 11:31 PM||Permanent Link|
The default DBISam Server ports are 12005 & 12006. However these ports don't
work very well when trying to connect to the server from some public wifi
hotspots like some airports, hotels, macdonalds and some cafes etc. These
ports appear to be closed in these places. Has anyone found a solution to
this like maybe other commonly open port we can use.

So, they're blocking outbound connections to certain *server ports* ? I'm
not sure why they would be concerned with which ports clients are connecting
*to*, as opposed to incoming connections to certain ports. This would
disallow many non-standard TCP/IP applications, such as Remote Desktop, etc.

I'm guessing its not so much that they are blocking certain server ports but
that they are just allowing the common Internet ports (maybe 80, 8080, 443,
110, 25 etc) and blocking the rest. Some of my customers also reported that
they could connect to their own DBISam server (12006/12006) from home or
from a branch office but not at some hotel wifi etc.
I often found that on these hotspots (hotels, macdonalds), whenever I had
trouble connecting to DBISam server on 12005, I also could not connect to
Windows RDP on port 3389. But for some reason, I had no trouble using other
Remote Desktop Solutions like TeamViewer and Logmein. I found that
TeamViewer uses 80 and 443 while Logmein uses 12975 & 32976 but will
eventually try 443 if unsuccessful (see below). I don't know for sure but I
think its the ports that are blocked on these hotspots.
Sometime back I tried running a DBISam Server on port 80, 8080 and 443 but
wasn't successful . Just wondering if anyone has found a solution.
