Form access over a LAN

[Marc Shapiro <m_shapiro@bigfoot.com>]

This is not Debian specific, so if there is a better place for me to 
post this, just let me know.

I just added a third compuer to my LAN.  I previously had only two 
computers set up with a crossover cable and the primary computer was the 
one with the modem.  Everything worked just fine.  Now, I have a third 
computer and they are all connected through a 5 port switch.  The modem 
is still in the old P166, but I am primarily using the Athlon 2000+ (you 
can guess why).  Most web page access works fine.  My wife has answered 
questionaires using forms without trouble.  When I try to access my bank 
account, or credit card accounts, however, it just sits there and does 
nothing when I enter my usrname and password.  I don't gt errors.  I 
don't get 404 messages.  No "Your name and, or password are not on file" 
type messages.  Nothing.  It just acts as if the button was a dummy that 
does not actually do anything.

Does this have something to do with th fact that the box is connected 
through a LAN and not a direct connection?  If so, how do I correct 
this.  I really hate having to hook the laptop up and dial in on it to 
deal with financial matters.  (The laptop is not much faster than my old 
desktop, and it is running Windoze -- for classwork.)

Any help appreciated.

Thanks,
