class-map type inspect esmtp has never been available. You must use the
policy-map type inspect esmtp.

 

policy-map type inspect esmtp smtp_inspection

 match body length gt 4000

  reset

 

policy-map global_policy

 class inspection_default

  inspect emstp smtp_inspection

 

When you try to use a class for application inspection, this is for matching
multiple items for a specific application inspection. There is currently no
class-map type inspect esmtp but there is a policy-map. This just means that
you cannot have a match on several items at once. For instance, if you
wanted to match body length AND a the method type before reseting the
connection, you cannot. In the policy-map, you can only define one match at
a time. A better example is http inspection, as it supports class-maps

 

for instance

 

policy-map type inspect http http_inspection

 match request body length gt 4000

  reset

 match request method post

  reset

 

policy-map global_policy

 class inspection_default

  inspect http http_inspection

 

this will drop any request with a body length gt 2000 "OR" method post.

 

The following config has to match both to reset the connection, meaning that
the request must be gt 2000 "AND" method post

 

class-map type inspect http match-all class_http_inspection

 match request body length gt 2000

 match request method post

 

policy-map type inspect http http_inspection

 class class_http_inspection

  reset

 

policy-map global_policy

 class inspection_default

  inspect http http_inspection

 

Hope this clarifies the use of class-map type inspects on the ASA

Hmm,

 

Guess that makes it kindof hard to do Lab2A and 2B.  Crap man.  This stuff
is killing me.  8.0(4) Does have the eSMTP inspection protocol support.

 

What do you pick the bugs in 8.0(4) or the missing protocols in 8.2.  My
hands are up in the air.

 

Segun,

 

ZBF most definitely supports eSMTP inspection.  FPM is not really an
inspection tool.  But you could create an XML template for FPM to match SMTP
packets most definitely.

Hi King,

I see it now.

There's no "class-map type inspect" for it but there's "policy-map type
inspect".

oj-gprsfw(config)# policy-map type inspect ?

configure mode commands/options:
  dcerpc             Configure a policy-map of type DCERPC
  dns                Configure a policy-map of type DNS
  esmtp              Configure a policy-map of type ESMTP
  ftp                Configure a policy-map of type FTP
  gtp                Configure a policy-map of type GTP
  h323               Configure a policy-map of type H.323
  http               Configure a policy-map of type HTTP
  im                 Configure a policy-map of type IM
  ipsec-pass-thru    Configure a policy-map of type IPSEC-PASS-THRU
  mgcp               Configure a policy-map of type MGCP
  netbios            Configure a policy-map of type NETBIOS
  radius-accounting  Configure a policy-map of type Radius Accounting
  rtsp               Configure a policy-map of type RTSP
  sip                Configure a policy-map of type SIP
  skinny             Configure a policy-map of type Skinny

Regards.

Hi King,

There's no application inspection for esmtp/smtp currently. Not even with
FPM on IOS.

Hi 

 

I have 8.2 in my ASA and it doesn't have "esmtp inspection" support. 

 

Any idea?

  dns   Configure a class-map of type DNS
  ftp   Configure a class-map of type FTP
  h323  Configure a class-map of type H323
  http  Configure a class-map of type HTTP
  im    Configure a class-map of type IM
  rtsp  Configure a class-map of type RTSP
  sip   Configure a class-map of type SIP

 

 

With regards

Kings
