HTTP redirection not succeeding

Here only what I'm receiving when using static NAT on PIX 501 6.3:

HTTP/1.1 400 Bad Request

Server: Microsoft-IIS/5.1

Date: Thu, 25 Jun 2009 14:37:37 GMT

Content-Type: text/html

Content-Length: 87

I'm using many static NATs and showing a correct result when showing (show xlate) also (show access-list).

Is it possible due of MTU on TCP packets? If yes, what command can change the TCP MTU? If not what's possible reason of the problem.

It it possible also caused by the cache server? I'm receiving it rapidly.

I'm using a direct connection without a proxy, where it may be?

try with clear xlate and with clear local commands

I don't think so, the translations are right and working fine.

Fixed now!

It wasn't a Cisco problem, just the because the costumer IIS was using port 82 rather than the default 80

Thanks for all of you!

Don't see how this could be an MTU issue...

You've established a successful HTTP connection and are receiving a 400 response code from the destination server. This looks like an application layer issue.

I fixed the problem before seeing your reply, but you gave the more logical reason.

Many thanks,
