Firewall problems

[Ron Douglas]

I have a very simple webservice that I want to access.
It works fine when there is no firewall in the way, but
when there is a firewall I have a problem. I get the
initial connection, but any further communication is
blocked. It appears to initally use port 80 and then
switch to another port. Is there a way to force the
webservice to stay on port 80?

Here is a sample of what I am doing:
Imports System.Web.Services
Imports System.IO
Imports ADODB

<System.Web.Services.WebService( _
Namespace:="http://Walkthrough/XmlWebServices/", _
Description:="User Registration.")> _
Public Class Register1
Public Function RegisterUser(ByVal MAC As String,
ByVal Facility As String, ByVal Address As String, ByVal
Address2 As String, ByVal City As String, ByVal ST As
String, ByVal Zip As String, ByVal FirstName As String,
ByVal LastName As String, ByVal Phone As String, ByVal
Email As String) As Int16
Dim con835 As New Connection
Dim cm835 As New Command
Dim rs837 As New Recordset
Try
con835.Open
("Provider=Microsoft.Jet.OLEDB.4.0;" & "Data
Source=c:\Inetpub\wwwroot\ValidateUser\validateuse rs.mdb;"
)
Dim recordsEffected As Object
Dim strSQL As String = "INSERT INTO users
(mac, facility, address, address2, city,st, zip, last,
first, email, phone, registered, usesleft) " & _
"VALUES ('" & MAC
& "','" & Facility & "','" & Address & "','" & Address2
& "','" & City & "','" & ST & "','" & Zip & "','" &
LastName & "','" & FirstName & "','" & Email & "','" & _
Phone & "','NO','10')"

' Execute SQL statement
con835.Execute(strSQL, recordsEffected)
con835.Close()
Return 0
Catch ex As Exception
Return -1
End Try

End Function
End Class

We have had two firewall problems in the last week.... neither client was ever
able to use Contribute 4 from behind their firewall. They are having to update
their sites from home.

What should I be telling their network administrators about how to resolve
this problem?

Make sure you've read the Tech note for users behind Cisco firewalls - if it
applies to your case [url]http://www.adobe.com/go/fc1a435a[/url]. You need to pick which
version of the file - either for mac or pc machines and then replace the
NetioFTP.dll file in the contribute program folder.

Also if you can try asking your network admins to create a port for you to FTP
through, instead of using the default port 21. You can configure in Contribute
to use a port either than that one. Make sure that your clients aren't running
a software firewall in addition, like zonealarm that is intentionally blocking
FTP traffic.

Make sure you've read this tech note for [url]http://www.adobe.com/go/kb400144[/url]
When I set my FTP settings from the default of "let contribute automatically
detect FTP settings" and instead "Choose FTP settings manually". Also click for
"Use Passive FTP" -+ "Use FTP performance optimizer and Use alternative publish
method".

Hope this helps
