How do firewalls that require authentication on the outbound deal with the user name and password? Is this a function of TCP/IP? Or a different level?
My company writes client server software for hospitals that connects to a specific port on the server side. We have historically requested that the hospitals firewalls be opened on that single specific port for outbound traffic. This was not a problem for the hospitals that we dealt with. On one installation, however, this particular hospital's firewall requires a login to go out to the internet. Our program choked on this and would not communicate with the server. The IS admin of the hospital said that he could not turn off the login for the single port, and so our program will not work behind this firewall configuration.
In our next version, we would like to address this issue. We want to be able to relay the login information. Is this specific to each brand of firewall? or is there a standard way of communicating to the firewall to login?
Thanks
