RE: PIX and IIS issue

If your IIS box isn't listening on an outside-facing interface, that could
be a problem.  Also, it may have a host-header which works inside --
http://servername -- but not outside -- http://webthing.somepurpose.com.

I'd focus on the IIS box though - the firewall doesn't seem to be part of
the problem.

Shahed,
        Are you saying that your Web server on the Linux box works fine,
with no changes to the PIX, where the Windows IIS server doesn't (using the
same IP)?  Is the IIS server configured to use an IP address other than "All
Assigned" (in the Web site properties)?  Just a guess, but you may have some
other IP address configured there (if I read this right)...

Hi!

I have a PIX connected to a switch on internal network and therein resides
my Microsoft IIS box. I can access ftp, ping etc from outside through
conduit and/or access lists but I cannot access http port from outside ?
Tried all clears - conduit, xlate, arp etc without any effect. Finally
thought that its nothing to do with the poor PIX and worked on the web
server. Replaced the IIS box with Linux and lo! it works fine.. I mean all
access lists and/or conduits for http, ftp, ping work fine. Now why doesn't
the same work with Microsoft IIS? The same Microsoft IIS works great with
all ports accessible on the internal network but inbound access for http
port from across the firewall through the outside interface is not working.
Any thoughts as to what's the issue? Is there a bug here?

Will virtual + aaa combo help here ?

BTW: PIX version 6.1(4) and IIS version 5.0+

Thanks in advance,
Shahed.
