Cisco Security :: Securely Access Exchange Server 2007 Through ASA 5510 Using Outlook

Dec 26, 2011

Is there any way to access a MS Exchange Server 2007 on Windows server 2008 through an ASA 5510 running 8.4 with a full MS Outlook client (not using OWA - web browser)?  OWA is currently working fine but I was wondering if access via the full Outlook client is possible and more importantly...is it opening up too many ports on my 5510?

Cisco Firewall :: ASA 5510 With 8.0.2 - Exchange 2007 Outlook Anywhere / OWA Users

Aug 15, 2011

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.

I can connect to Internet perfectly fine.  I can even VPN back into my office.  However, once connected via VPN and I launch my Outlook Client, I'm not able to connect to get emails.  When I run a "netstat -a", I get my "SYN_SENT" to all my office domain controllers and exchange servers.However, if I connected via my Starhub USB Broadband dongle, everything works perfectly fine.What settings do I need to do on my router?  I tried port forwarding and application rules but none worked.

Cisco Firewall :: ASA5510 - Outlook Clients Disconnect From Public Exchange?

Apr 4, 2011

We have a setup where clients on the internal network send/receive their emails through Microsoft Outlook client, while the Exchange server is hosted on the internet, outside the organization.The clients are connected to a Cisco switch, behind an ASA5510 Firewall. The Firewall is connected to an internet router, with double NAT (On the ASA and Router).

the outlook clients disconnect from the Exchange server, sometimes for hours, and then reconnect again. During these disconnections, the same client PCs are able to browse the internet normally. There are no restrictions for the traffic going from the inside to the outside. During the disconnections, if we try to connect using a public IP bypassing the ASA & router,.

""The SSH2 protocol specification requires that a SSH2 server support the diffie-hellman-group1-sha1 key exchange algorithm. This key exchange algorithm is considered strong, but faces a potential weakness in that the same prime number is used for all key exchanges."

Cisco Firewall :: ASA 5510 Barracuda Exchange Emails Deferred

Nov 29, 2011

Our ASA 5510 has been in place for nearly two years, we never have any issue what so ever with it. All along the ASA has been using the default policy. Lately, we beeen getting email deferred in our Barracuda Spam firewall. Google quickly reveals that ESMTP does not play nice with Barracuda witch i disabled eventhough we haven't had any issue with it before. However, the issue remains, we still getting email deferred in the barracuda.
 
While doing more troubleshooting on the ASA, I constated when issue the command show local-host + IP of the Barracuda, there is an IP address in outside of the interface that can get up to 96 UDP port 53 connections with the Barracuda, this connection never get lower than 20! However, when checking the default setup for the Barracuda, i have the values below:
 
Incoming SMTP Timeout: 20
Message per SMTP Session : 8
Maximum SMTP Error SMTP Session: 2
Maximum Connection per Client 30m:40
 
My question is if that ASA show up to 96 DNS session with an outside host to my barracuda, won't that push the barracuda to play email deferred timeout ? Should I change the barracuda default setting? Or should i change the connections limits for the Barracuda in the ASA?

Cisco Firewall :: 5510 Exchange Active Sync Stops Working

May 8, 2012

I know that I've run into this before but I can't remember the fix.  I have a 5510.  The 3 interfaces involved are INSIDE, OUTSIDE, and GUEST. Corporate users are allowed to put their iPhones on the Guest network, but the problem is that their Exchange ActiveSync stops working.  It is tied to the external DNS name of the OWA server (we'll say webmail.abc.com).  So the users are funneled out one public IP on the OUTSIDE interface and are trying to communicate with the outside of the OWA server, which is NATed to another public IP on the same outside interface.  What do I need to do on the ASA to allow users on the guest network (behind the GUEST interface) to access the mail server using its public IP (behind the INSIDE interface)

Cisco Firewall :: ASA5510 / Accessing Exchange Server From DMZ?

Aug 16, 2011

We have a ASA5510 with a webserver in the DMZ network 10.2.2.0/24. We now want this web server to be able to access the Exchange server in the Inside network 10.1.1.0/24. I researched this and it seemed straight forward according the the Cisco document below:

[URL] 
 
I'm looking to do this with smtp so I added these lines to the config:

access-list dmz extended permit tcp host 10.2.2.2 host 10.2.2.30 eq smtp
 
The configuration line:access-group DMZ in interface DMZ Already existed in the configuration so didn't need to be re-entered.

ASA Version 8.0(4)

Cisco Routers :: Exchange Server - Port Forwarding On 2811?

Sep 18, 2011

Basically the problem that I have is that I have a new Exchange server sitting on 192.168.12.2 IP address and on the router I have this NAT enabled
 
ip nat inside source static tcp 192.168.12.2 110 212.115.5.5 110 extendable ip nat inside source static tcp 192.168.12.2 25 212.115.5.5 25 extendable
 
The Exchange can receieve emails but it will not send them. It cannot make connection to any of the smart hosts on port 25 or can't even send mail using DNS. When I run telnet my.smarthost.com 25 it will not connect but if I run that from the router then it connects fine.

Cisco Wireless :: RV220W / Unable To Connect To Exchange Server With IPhone

Aug 21, 2011

I just recently installed a RV220W at my office and (almost) everything works fine. I have noticed that when my iPhone is connected to the RV220 wi-fi network, I get the message "The connection to the server failed" when checking my email. If I disable the wireless on my iPhone, it connects up to the exchange server perfectly fine so it must be a setting with the wireless somewhere but I cannot find it anywhere.....

This works fine through a LinkSys RV042 in one location and a LinkSys WRT54GC in another, but fails through the DIR-615 B2 (2.24 firmware) at home. I'm guessing it's blocking something needed for the MAPI connection.

Since I have installed my new router, a Linksys EA6500, I have many problems to connect to my Exchange Server, which is located in my house, via Wifi. I tried to synchronize my Iphone and my Samsung tablet but it won't work. Most of the times I get the message that the Exchange server cannot be connected. When I turn off my Wifi en connect via my mobile provider I have no problems. When I am on a third party wifi I also can connect my server. Seems my own wifi causes lots of problems.

Cisco AAA/Identity/Nac :: ACS 5.1 With Outlook Web Access

Jun 26, 2011

I have an AD User, lets call them workauser and there password just expired, so next logon to the domain they need to change there password.They decide while at home to connect to Outlook Web Access, which authenticates to via ACS 5.1 to AD, when they try and connect they are denied with the following message in ACS -
 
24407 User authentication against Active Directory failed since user is required to change his password Authentication failed.
 
Check the password expiry under Account options in the properties of an  external database user. If the password is expired and the Enable Change  Password is turned on in the Users and Identity Stores: External  Identity Stores > Active Directory page, then the password will be  changed.
 
Now, our OWA is not configured to allow password resets, so they must call in to have there password reset, or they can connect via VPN and our ASA allows them to change there password as configured under Identity Stores > Active Directory > Enable Password Change
 
This VPN password change is successful although OWA still will not work. The only way to fix it is to select passwsord does not expire within AD. Let it replicate, then de-select password does not expire and let it replicate.
 
This is pointing to a OWA issue in my opinion, although ACS is somehow involved, is it possible that ACS caches authentication, or because OWA does not allow password resets, it keeps responding with user required to change his password?

Cisco Firewall :: 5510 Security Plus To Terminate Client VPN Access For External Support Team

Aug 7, 2012

I have a customer that wants to purchase an ASA 5510 security plus to terminate client VPN access for an external support team. The customer claims to want URL content filtering/proxy which leads me to suggest a CSC SSM 20 plus module. But upon further conversation, he mentioned wanting IPS. In this case, the customer does not seem to know the difference between the URL content filter/proxy and the IPS and uses both terms interchangably.
 
1. What would you suggest in your expert opinion would be the best module to get for this customer? IPS or CSC
 
2. If I go with the CSC module, where can I find good documentation on how to configure it and get it up to date?
 
3. does the CSC module provide any web proxy functionality?
