Cisco Firewall :: ASA 5520 CSC Module Per Subnet / IP Group Inspection Profile
Sep 7, 2011
verify if the ASA 5520 CSC module way of applying security policy (http, smtp, pop3, etc.) is per network/subnet or group of users? Based on my understanding through reading, web and email protection profile/config is global. It will be the same to every network user that is redirected via service-policy config on the ASA.
Scenario: I have two VLAN, guest and employee. Of course guest and employee have different web filter profile. Can i configure it such that guest web-filter profile is not just strict while employee's access is limited only to productive internet sites.

ASA 5520 running 8.4.5:We had an issue with a remote SMTP connection getting screwed up as a result of ESMPT inspect.It took me 3 hours of troubleshooting the SMTP connection before finally figuring out that the firewall was the culprit. What really through me off was that I saw nothing in the ASA logs (warning and above) that showed packets were being dropped. I'm probably crazy but I thought I remembered seeing entries in the log when packets were dropped due to a type of inspection (specifically, I remember entries in the log saying something to the effect of packet dropped due to ESMPT inspect, packet too big). My quesiton to Cisco TAC was: Is there a simple way to have the log give a warning every time a packet is dropped due to any inspection rule, just like we can see any drops due to ACLs? So far the only answer has been a complex list of log changes to allow debugging and notifications of certain events. This isn't something I want to roll out to all my ASAs.

I have an issue with Cisco ASA 5520, The summary is below!
Packet # 1 on inside capture the Call-ID was: Call-ID: 2a54f680-
a5d1de2a-160c-164070a@10.7.100.1
Packet # 1 on outside interface the Call-ID was: Call-ID: 2a54f680-
a5d1de2a-160c-164070a@149.5.33.44 --- this bcz of the inspection.
Packet # 2 on outside capture the Call-ID was: Call-ID: 2a54f680-
a5d1de2a-160c-164070a@149.5.33.44
Packet # 2 on inside capture the Call-ID stay: Call-ID: 2a54f680-
a5d1de2a-160c-164070a@149.5.33.44 --- this is the problem.
(This suppose to be Call-ID: 2a54f680-a5d1de2a-160c-164070a@10.7.100.1)The inspection should change the Call-ID for the incoming packet as it did with the outgoing packet. Whenever, the CM receive the trying message with different Call-ID it considered as new session and it keep sending invitation messages for the SIP provider.NAT is enabled.

I need to allow traffic between webserver in dmz and mssql (Microsoft SQL Server 2008).MSSQL use dynamic port (now it is 63796) and this cannot be changed.
Basically, I can allow such traffic using next configuration:access-list dmz extended permit tcp host 1.2.3.4 host 5.6.7.8 eq 1433access-list dmz extended permit udp host 1.2.3.4 host 5.6.7.8 eq 1434 access-list dmz extended permit tcp host 1.2.3.4 host 5.6.7.8 eq 63796
But, I would like to add mssql inspection and I did the next:
class-map class_sqlnetmatch port tcp eq 1433policy-map global_policyclass inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect ip-options inspect netbios inspect rsh inspect rtsp inspect skinny inspect esmtp inspect sqlnet inspect sunrpc inspect tftp inspect sip inspect xdmcp class class_sqlnet inspect sqlnet service-policy global_policy global

I currently have the default inspection engine configured in my firewall to inspect http traffic. I noticed that the ASA will drop packets when visting legitimate websites. I've tried googling for a workaround but have been unsucsselful. How can I exclude some websites or IP's from being affected by the inspection engine?

I'm looking into starting a file sharing server (think this is what its called) which will allow people to login into one of my PC's over the internet and download my files. My goal is to allow family members and friends to access my files and only specific files on this PC. The files could be family videos as well as pictures. Some video files will be in excess of 10gb along with typical jpegs and what not. I'll probably be running windows server 2008 on it. I'm also considering allowing people on some other forums that I'm a member on (cars, hobbies, ect) and allowing people to host vids on my server. My current IP provider is Comcast and I'm on a Dynamic IP so wondering how easy this is or if its recommended I get a static IP.
I' am looking for some articles that you'd recommend on this. I'd also like to have password protection / or login criteria so car members aren't able to view all my family videos, but can only log into some folder labeled (cars) and not my folder labeled family. Or another option would be that people have to login before they are able to even see what folders are accessible.For instance car members could only see car folders Family members could see anything stored on the PC?

i've configured 4 connection profiles (IT,HR,Admon,VIP) on the asa everything works well, but our boss wants to know if it's possible to assign the right connection profile without using group drop-down list, what he wants is to use a unique connection profile (non-default) and via radius attributes using ACS 5.X to assing the right profile.

Does the ASA treat an object-group with a network-object containing a range of IP addresses as a netmask? For example, I can apply this configuration without the ASA throwing any errors though the configuration calls for a 'net mask':
object-group network test
network-object 192.168.0.0 192.168.63.255
?
network-object-group mode commands/options:
A.B.C.D Enter an IPv4 network mask
sh run ob id test
object-group network test
network-object 192.168.0.0 192.168.63.255
I found that in the documentation it requires a netmask as oppose to a range. Is this a bug in the code? I am running code version 8.0(5)23 on a 5520. If this is not a bug how does the ASA treat this type of configuration when applied to an access list? When I ran a quick packet trace and denied access from that range it looks like the ASA doesn't read that configuration properly.

I have two Nexus 5520 running 5.0(3)N1(1c).
I have both boxes heading off to ACS for TACACS lo gin authentication and for command authorization. When I first set things up everything works fine. I have a shell profile configured in ACS with Cisco-av-pair*shell:roles="network-admin" to set the network-admin role. I even have command sets configured to deny the use of configure terminal as I am using switch configuration profiles. Everything runs fine. User lo gins are authenticated by ACS and users have the correct command set applied to them.
The problem comes when I make a change to a shell profile in ACS. Even something as simple as changing the name of a shell profile causes the 5520's to crash as soon as I try to log on. If I unplug the management link so that the TACACS server is unavailable I can log on fine with the local admin user.
The NEXUS console reports this error. (amongst many others)
EDNAM-NEXUS-2 %$ VDC-1 %$ %SYSMGR-2-SERVICE_CRASHED: Service "Tacacs Daemon" (PID 4331) hasn't caught signal 11 (core will be saved).

Could this be a bug with Nexus/ACS?

I have multiple customers and servers behind my ASA5510s. After moving a new customer with an FTP server behind the firewalls, they immediatly had issues with customers connecting to their FTP server. I had the default inspection rules running regarding FTP. After removing the "inspect ftp" from the global policy their issues went away. Since this is a larger customer I can't force them to change their server, I need to accomodate and fix this on the firewall. I left the "inspect ftp" command out and there have been sporatic issues from other customers, unable to connect to outside FTP servers from the terminal servers and timeouts and disconnects to our own FTP servers.
This is what I "think" is the solution.. I added a second inspection policy after the default one and only added "inspect ftp" to it. Then I used the "exclude" option to exclude the new customer. That new customer is fine and things are better, but still not working right. Does the following config accomplish what I want?? Does the exclude ACL get what I need or do I need an "include" or permit statement in that ACL?
object-group network DM_INLINE_NETWORK_10 network-object 172.24.X.0 255.255.255.0
object-group service DM_INLINE_TCP_1 tcp port-object eq ftp port-object eq ftp-data

Options a user may reside in Austin, TX and I want the user to utilize the local proxy (i.e. texasproxy:8080). We currently only require the user to enter the RSA passcode and username to authentication (RSA/AD username are identical). Is there a way to have the user authenticate via RSA and have the user's AD group membership (TX) assign the user the specific IE proxy settings? We are utilizing an ASA 5520 on 8.2, but we are willing to upgrade to newer IOS or even consider anyconnect to resolve this issue.

We have several customers running ASA 8.4x code and all seem to be plagued with the ESMTP inspection bug CSCtr92976.I have tested this in the lab with an ASA 5505 running 8.4(1), 8.4(2) and 8.4(4)1 & 8.4(4)3 and the behaviour is always the same. I have an Exchange 2007 server and I can see in the logs the following messages:
2012-08-10T13:04:37.331Z,EXCHANGEDefault EXCHANGE,08CF3610468A42D7,3,192.168.102.28:25,192.168.250.26:52756,<,XXXX XXXXXXXXXXXXXXX,

This is with the default ESMTP inspection enabled. I have also created a custom ESMTP inspection policy that does nothing but log and the behaviour is still the same. Sometimes traffic will pass but most of the time it won't. The workaround is to just disable the ESMTP inspection.

By default ASA applies DNS packet inspection with a default (maximum) packet size of 512bytes as recommended by RFC 1035, anything above is dropped.
I have a customer that is trying to use larger packet sizes due to extension mechanisms for DNS defined in RFC2671.
My question is , is it safe to increase the default packet size in the DNS inspection thus applied globally for all DNS traffic, or should / can we apply a policy that applies only to this specific customer ?

I have two Cisco ASA 5520's running software version 8.2(2) set up in a HA pair. The L2L vpn is set up and works as expected between this site and another. The issue is that every few months, one subnet of the VPN, the same one all the time, stops forwarding/receiving traffic. The device in the remote location is not a Cisco device but I am certain the issue lies with the ASA as when I fail over to the slave device the VPN works again, failing back again however stays with the subnet still not passing traffic. I need to reboot the device before it starts forwarding traffic on the subnet again.

I was under the impression that all Cisco ASA firewalls shipped with a default inspection policy.
Example
policy-map global_policy
class inspection_default
inspect dns preset_dns_map

can I build this myself? Why is it missing (I have two other ASA 5505s here that also do not have it). What would I do to rebuild it?

On FWSM (running version 4.1 in my case) the default global policy uses the following class map:class-map inspection_default match default-inspection-traffic
What "default-inspection-traffic" includes? Is it all traffic? If so, do I really want all my traffic to go through the inspection engine? I would imagine this would have a performance impact on traffic that is not part of the protocols being inspected.

I am having issues with PXE boot images for PCs cannot be loaded from remotely.The diagnosis revealed that SunRPC & TFTP were being inspected by ASA causing drop of packets.So I excluded these two inspections for the particular server behind the firewall. It seem to resolve the issue for instance but it crawled back again.
Is there a way that the inspection can be turned off for that particular server at the IP level?

I just started configuring AnyConnect with ASA 5520 that uses Cisco SecureACS to pass radius authentication. I configured two profiles with different split tunnel restrictions and what I discovered is that when the client connects to the ASA, they are provided a choice of these two groups (I guess there is no way to restrict this) and I can log into either one with any user account. How do I restrict this so that the user can only use one profile? Currently users capable of VPN would be placed in one specific AD group so that is what SecureACS checks. Is there a sample configuration guide to handle multiple profiles with different levels of access?

I have a branch office set up were all traffic goes back to the core, iincluding internet acces.
It has been working fine for a year, but recently I have started to see the firewalls Asa 5505 closing the connection and stopping the phone from answering the calls.
I have skinny inspection turned on all my branch offices, but had to turn it off at the one site to get one of my phones to registered.
I haven't made any changes to the network that would trigger this issue, such as upgrading phone firmware.
My firewall is configured for default deny, other than Skinny (tcp 2000), do I need Skinny inspection to be turned on?
It's turned on my 5 other branches.How can I debug why the skinny inspection is closing the connection?As a separate note this phone is part of a pool of phones that shares a common DN, would this be causing the issue?

I have a home office with multiple VLANS/subnets I have many VPNs that connect only a specific subnet to a specific remote offfice. On a 5520, can I create a S2S VPN to different remote offices that have the same IP scheme, but from different home office subnets? For example at my home office let's say I have two independant, distinct VLAN/subnets: 192.168.140.0/24 and 192.168.150.0/24. Can I create an S2S from the 140 subnet to a remote office with a 10.10.10.0 addressing scheme and another S2S from the 150 subnet to a totally different office also with a 10.10.10.0 scheme?
