mobile website goes to login page but not further

[SJ]

I have a mobile web application running on a server at work. There is a
strange thing happening though:
1) I can access and login to my mobile web app from any internet browser.
(good thing).
2) I can access and login to my mobile web app from any Palm Treo web
browser. (good thing).
3) When I use a regular mobile phone (samsung/motorola...etc) and load up my
website on the browser, it takes me to the login page. Now, when I enter my
username and password, it doesn't move forward. After about 5 mins it comes
back with a "Data server unavailable" error.

Now why would my web app work on the Treo and not on ANY other mobile phone?

Btw, I installed the exact same webapp on another server (on a different
network) and tried the above phones and it works just fine. So I know its
not a carrier signal issue.

Any ideas?

thanks,

Have you tried with other test pages that bypass the login page?

Well, I've designed the application so that if you try to go to another
webpage directly, it will redirect you to the login page. And this works.
So, say if i type xxx.xx.xxx.xx/wap/Index.aspx, it redirects me to the
/wap/Login.aspx page.

Now when I type the username and password, it behaves the same way as noted
below in my previous posting.

I was just suggesting removing the login requirement, and see if you can
just go straight to the target page (as a test)

Update: Apparently the request doesn't reach the server when I hit the Login
button. I know there is a DMZ on the network. Would that pose a problem for
WAP?
