Trying to connect to a Virtual Private Network from an
outside connection.

Under the ODBC configuration; I have filled out the Network
tab, TCP/IP text feild to the according VPN -> IP address.
I cannot get a connection. The message I get is...

"Unable to initilize requested communication link"

I have experience using Sybase in network settings, but not
in a VPN setting. I assume what I have written above is the
only difference needed between the two to establish a
connection.

Is my thought process wrong? Can anyone help with this
error message?

- Which version/build of ASA are you using?

- Open a command prompt. PING xx.xx.xx.xx (specifying the IP address of the server). That's got to work first.

If that does work, then go to the ODBC network tab.
Check ON TCPIP, and specify HOST=xx.xx.xx.xx (the same IP address from above).

Then go back to the main tab and click Test Connection.

Note that some VPNs don't allow ICMP packets through, so if that's the
case, ping won't work. Tey dbping -c <connection string>. Then you can
adjust the connection string until it works, and then use dbdsn with the
same connection string to create the dsn. So, if

dbping -c <blah>

works, then use

dbdsn -y -w DSNName -c <blah>

to create the DSN.
