ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

Hi,

We have a ASA 5510 which was running 8.0.2, we recently upgraded it to 8.2.5 and since the upgrade remote users for exchange 2007 are not able to download any large email attachments(over or close to 1MB). This is only happening to Outlook anywhere users or OWA users who are connecting to the exchange server using https(443) externally. If the same users connects internally they do not face any issue. When i check the logs on ASA i am gettings lots of RESET-O and RESET-I entries. Looks like the connection between the client and the server gets reset.

Exchange server sits on the inside network with PAT in place.

Any ideas....

ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

Inspect: http BlockUrlPolicy, packet 10916492, drop 4211, reset-drop 2291

Can you turn off http inspection temporarily and test again?

Hi Lcaruso,

I have already tried it and that didnt make any difference.

ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

The RESET-O are generated when the SERVER is not listening on that TCP port.

The RESET-I  are generated when the client tores down the connection to the server.

Both are Informational level logging , which is nothing but what's going with the traffic from your firewall , normally this is set up to error level but then again it depends upon your company preference.

As far why the clients are not able to down load large files could  be associated with the http block url policy. But since you said that turrning off http inspection didn't help  than I would like to know that does the server lets you download the big files when you are inside the Firewall in the same subnet as the server + different subnet if any but inside the firewall ?

ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

Hi Manish,

Thanks for taking the time to reply, Yes turning off the http block url policy doesnt make any different, and the large email attachment issue is only face by the external clients who are coming via the internet. These clients use Outlook anywhere and OWA (https 443) to access emails. Internal clients do not have any issues and there email continue to work as normal.

Re: ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

Hi,

Sorry for the late reply but for some reason I am not getting emails when from cisco when someone replies to the Post. Anyway, Can you please explain what error do you get when sending attachment of larger size ? Is it something like "Attachment size exceeds the limit" or there is no error and email never reaches the other end.

Can you also post the configuration of the service policies that you have ?

Also, post the error message send back by the Exchange server if any.

Thanks

Manish

Re: ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

Hi Manish,

As i initially described, problem is not with sending large email, its when the user is connected to Microsoft Exchange over 443 (RPC over HTTPS) and they have received an email with large attachment (in this case over 1 MB). Their outlook just shows updating inbox, and if they try and download that email through OWA response is similar where its start downloading the attachment and then slows down to 0bytes per second.

Service policy output is already been provided in the earlier post, no errors in exchange event log.

Thanks..

Can you turn off all inspection and test again?

Enthusiast

Re: ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

or there's this...

Test attachement problem from a known ip address externally.

You'll need three simultaneous captures:

1. capture on outside interface from/to any from/to public ip of exchange

2. capture on inside interface from/to any from/to private ip of exchange

3. capture on the exchange server with wireshark latest version

There's a method to download them as wireshark files from the ASA. 

Once you have those three simultaneous captures, you'll be able to trace each

packet's request and response. For example, a client packet hits the outside

interface of the ASA, then is seen on the inside interface, then is seen hitting 

the server. Then, the server is seen replying to that packet. Then that reply hits

the inside interface of the ASA, then that same packet is seen exiting the

outside interface of the ASA.

If one packet is dropped in this, you will see where it happened and you will

confirm where the problem exists. If resets are involved you will see those.

Hi,

Are these users connecting to the OWA/outlook over some kind of remote VPN ?

I think we shouldn;t drag this any more , Can you revert back to the Older Code ? If yes than :-

1> If it starts working after you switch back to the older code than Open a ticket with Cisco.

2> If it still doesn't work than You need to look further towards the Exchange server and check if something got changed or updated etc recently.

Re: ASA 5510 - Exchange 2007 Outlook anywhere/OWA issue

Guys,

I found the problem, I had a IM block policy on the LAN interface, as soon as i removed that policy, issue was resolved, here is the part of the service policy config posted earlier, which was causing the issue.

Interface LAN:

Service-policy: IM

Class-map: imblock

Inspect: im impolicy, packet 75996195, drop 4, reset-drop 0

It still doesnt make sense to me why would this policy create such problem? but anyway

I thank you all for your help.

Never hurts to turn off all inspections in such a case. Quick and easy to test.

Glad you got it resolved.
