Authentication through VBA- instructions

I have made an Access VBA application that runs on my local PC. The appl. is connected to an external MS SQL-database on a server. The connection use an IP-adr, a username and a password and it works fine. But before I can conntact the SQL-server I have to do a Authentication on the web with username and password,looks like this: I think it is a fireWall or something. I have got the the username/password and it works fine when I run this on the browswer manualy before I run my application.
My questiion is: How can I give this authentication in my application instead of manualy on the web. Is it possible to do this by instructons(VBA) ?
Thank you.

The question is the firewall on your end or theirs?

What you need to do is create (or have the remote end)  a passthrough on the firewall.  What a passthrough essentially does is say that anything coming from or to a given address is allowed to go through without authentication,  but only if it it comes from this IP address.

The firewall is on theirs side and I am allowed to go through. I have got the nessesary username and password. The question is how I can automate this login in my application. I want to put  : + username + password in my code(VBS or VB) code(instructions), how can I do that.
Thank you
