Are you sure that the server is listening on the correct IP address?
I have seen this behavior when the server was listening on the localhost
loopback instead of the public IP address of the host...

Is that really a valid IP address (looks like an octet in the address is
missing) or did you edit the text before you pasted it here?

The IP address you list here isn't valid. Check
the original sql.ini file to confirm that.

Check on the remote server what IP address the
server is actually using too (assuming the
above was just a transcription typo). If its
using the loopback port (127.0.0.1) fix that.

So to check what address the server is using I just issue an
'ipconfig' command, right? And check the 'IP Address'? If
so, that is the address that I can ping remotely and that is
the address I have in my SQL.INI file.

I can connect to a MS SQL Server database on the remote
server, just not the ASE server. So maybe it isn't a network
issue.

No. ipconfig (ifconfig on Unix) only tells you
what interfaces the operating system has configured.
You would need the Windows equivalent of netstat
to see which IP addresses and ports applications
are using. Of course, a quicker way is to just
look at the ASE server's errorlog. Its in the
first few startup lines.

Your other post mentions you have two interfaces.
Kevin's given you the details for using both.

in my case it was the Firewall that blocked the remotely connection to Sybase .
