Cisco PIX 501 Blocking www

When you state " All inbound rules work 100%" are you referring to the inbound traffic to the outside interface or the inbound traffic to the inside interface. Also, are you trying to apply an access list to the inside interface? In the config above there is no access applied to the inside interface.

Hi,

Yes I'm referring to inbound traffic on the outside interface which is working fine.  I'm trying to apply an access lists to the inside int.  Can you provide an example of the required access lists please

Many thanks in advance!

Hi there - you cannot use the "out" keyword in PIX software 6.x. At minimum 7.x is required. This cannot be installed on a PIX 501 as it is not supported.
There might be a work around though... what exactly are you trying to accomplish? Block web access for inside users? What?
Cheers!

Hi,

Yes I'm traying to blanket block certain protocols for all internal users, i.e ftp

Thanks
Alex

So you just block using the "in" keyword for the inside interface since you can't use the "out" keyword.
Like this:
access-list inside deny tcp any any eq ftp
access-list inside permit ip any any
access-group outside in interface inside
to add more rules, just add another line above the first one with your protocol in the place of X

access-list inside deny tcp any any eq X
Cheers!

Thnaks will try this tonight and let you know how I get on.

kk!

Hi Pugglewuggle,

I've applied the access list detailed above (FTP), but this kills "all" outbound traffic (i.e msn, PPTN, as well as www)

Thoughts?

It shouldn't. Can you please post the new running-config so I can take a look?

:) great thanks that works!

So my "interpretation" of "access-group inside in interface inside" is:-

""allow access-list "inside"  to the "inside" interface""  I would have thought the logic would be:-

"access-group inside in interface outside"

I guess the above would be the logical command, but any info as to Cisco logic would be great!

Sorry to be a pain, but I've justed started configuring my Cisco PIX 501 this week, but already making some good progress i.e. PAT to my test Exchange mware box (& I'm not using PDM at all, as I feel it detracts from using Cisco and prefer to use CLI)

Good for you!
Here is the Cisco command reference on the access-group command to answer your questions:
