ftp script with additional firewall login?

[RobJordan]

I am familiar with a standard ftp login script
but I am having trouble with one that first requires a login to the firewall first.
I am not sure if I should use the quote command to do this.
I have posted the manual login below that I am trying to automate.

Thanks in advance,

Robert

We use a firewall here and the syntax is
ftp firewall
remoteuserID@firewallID@hostID
Remotepassword@firewallpassword.
