Wireless Access to ONE web Server problem

PLEASE CANCEL THIS POST - turns out it was most likely an isolated (to that access pojnt) incident...thanks
----------------------------------------------
I've run into a strange(?) problem with a mail server's web interface - one user's laptop can access anything & everything on the web except the mail server. Myself and other users can access the mail web interface from multiple different locations outside of the LAN, but not this laptop user via wireless.

LAN Details:
>Class C /29 subnet
>router
>firewall: NAT w/ MIP'd public IP's to mail server's primary & seconday domains (firewall of course has policies in place allowing mail (POP & IMAP), HTTP/HTTPS, ping, telnet)
>private IP's assigned (192.168.0.0/24)

Mail server - MDaemon w/ WorldClient (running on port 3000 - accessing via IP address, not FQDN because of port)

Laptop: Dell [Windows XP SP2 patched to date]

Laptop on the LAN:
I can...
>access the mail server's web interface (both via the public & private IP's
>access server, etc.
>ping all private and all MIP'd public IP's on the LAN


Via wireless connection from outside the LAN:
I can...
>access anything on the web EXCEPT their mail server
>ping their LAN's router, firewall, mail server and a pc that has a MIP for pcAnywhere access
>ping & trace any other public IP's

I cannot...
>access the mail server's web interface

[Also attempted connection with XP firewall off, f.y.r.]

Any ideas on where to look?

Thanks,
Steve

 

sounds like a routing table issue.

what is the wifi card connecting to?

 

if you're referring to the routing table on the router, it looks fine - lists the actively used 3-4 public IP's that are MIP'd to internal private IP's, all with the correct common MAC

the wireless connection at the time (tried twice) was a public one outside of a CompUSA - I've since told the guy (I'm not onsite) to go try a couple different wireless connections to see what happens

tks
