Firewall/jsp issue

[Michael Magdech]

I have a client who is on SBC Ameritech using pppoe with a Speedstream 5861
modem.

And they run good with that configuration.

When I put in a Sonicwall tele3 and configure it with NAT all seems to work,
except when the client goes to a web site with a jsp script. Then the PC
that is attempting to go to that web site times out with 'Action Cancelled'

This is a mission critical issue since they access a jsp web site for
business use.

I have taken the tele3 off-site and tested it behind other modems and
routers without any problems.

Recently I went to the site with a business partner and his notebook works
fine, but all others including mine still time-out on jsp pages. We have
gone over his notebook with a fine tooth comb and can't find what's
different.

The Speedstream modem is set to a static IP with an internal IP address of
192.168.254.254 and we tested with the firewall disabled.



Any ideas?



All help appreciated and thanks in advance.

This sounds really odd; the output produced from a JSP should not normaly
differ from the output of any other server-side solution (PHP/PerlASP/etc.)
Typically they all produce normal pages containing html, plaintext, etc.
Thus it should not be a Java/JSP -specific problem. I would check the
firewall if it could have some strange configuration issue when it comes
to URLs with .jsp (probably not), and/or check if the site(s) where you
get a timeout sends some special/strange/odd/extra header(s) in the
response-data generated by the given JSP-page which your firewall could
be choking on.
