Cisco Firewall :: HTTP Inspect In ASA 5510 Messes Up SVN Authentication

May 13, 2013

I have a strange problem in my ASA 5510 firewall. I turned on HTTP inspect policy to block certain URLs, but that destroyed svn communication. Interestingly, if I use simple web-browser to access svn server - it works, but any svn-client requests fail with an error "Could not read status line: An existing connection was forcibly closed by the remote host". I did some packet sniffing, and discovered that with HTTP inspect off the Webbed request is answered, but with HTTP inspect on it is rejected with an error unauthorized. Here are examples of success and failed conversation packets:

Success:
1. <Client-IP> <Server-IP> WEBDAV WEBDAV:Request, PROPFIND /svn/repos/myrepo/trunk  {HTTP:3, TCP:2, IPv4:1}
2. <Client-IP> <Server-IP> WEBDAV WEBDAV:HTTP Payload, URL: /svn/repos/myrepo/trunk  {HTTP:3, TCP:2, IPv4:1}
3. <Server-IP> <Client-IP> TCP TCP:Flags=...A...., SrcPort=HTTP(80), DstPort=58882, PayloadLen=0, Seq=4139355337, Ack=3464798063, Win=258 (scale factor 0x8) = 66048 {TCP:2, IPv4:1}
4. <Server-IP> <Client-IP> WEBDAV WEBDAV:Response, HTTP/1.1, Status: UNHANDLED HTTP Status Code, URL: /svn/repos/myrepo/trunk  {HTTP:3, TCP:2, IPv4:1}
 
Failure:
1. <Client-IP> <Server-IP> WEBDAV WEBDAV:Request, PROPFIND /svn/repos/myrepo/trunk {HTTP:3, TCP:2, IPv4:1}
2. <Client-IP> <Server-IP> WEBDAV WEBDAV:HTTP Payload, URL: /svn/repos/myrepo/trunk {HTTP:3, TCP:2, IPv4:1}
3. <Server-IP> <Client-IP> TCP TCP:Flags=...A.R.., SrcPort=HTTP(80), DstPort=1137, PayloadLen=0, Seq=1075661931, Ack=4049054406, Win=64240 (scale factor 0x0) = 64240 {TCP:2, IPv4:1}
4. <Client-IP> <Server-IP> TCP TCP:Flags=......S., SrcPort=1138, DstPort=HTTP(80), PayloadLen=0, Seq=1032908784, Ack=0, Win=64240 ( ) = 64240 {TCP:4, IPv4:1}
5. <Server-IP> <Client-IP> TCP TCP:Flags=...A..S., SrcPort=HTTP(80), DstPort=1138, PayloadLen=0, Seq=4184445498, Ack=1032908785, Win=8192 ( Scale factor not supported ) = 8192 {TCP:4, IPv4:1}
6. <Client-IP> <Server-IP> TCP TCP:Flags=...A...., SrcPort=1138, DstPort=HTTP(80), PayloadLen=0, Seq=1032908785, Ack=4184445499, Win=64240 (scale factor 0x0) = 64240 {TCP:4, IPv4:1}
 
Packet # 4 is an actual differentiators.

I found one mentioning of that error with that assessment: "Older firewall/proxies do not understand the Webbed related HTTP requests for accessing Subversion using HTTP{ URL} in that post But not any useful tips.

Cisco Firewall :: ASA 5510 Can't Inspect And Intercept For HTTPS Traffic

Feb 23, 2011

I want to block some social networking sites using ASA 5510-CSC-SSM, As I searched and come to know that ASA 5510 can't inspect and intercept for https traffic because it is encrypted while traversing throught the ASA. I want the ASA to make functioning for https too, not only http. Can i perform this task by updating any software on existing device?

Cisco Firewall :: 5510 Inspect SIP Dropping Request Message Packets

Mar 17, 2011

I have 2 ASA 5510 firewalls at 2 different sites. Both running on version 8.0.4. Users are using an Instant Messaging type of application provided by a local telco here which is able to send and receive SMS using SIP (from the packet capture that I've done).
 
When users use the IM in site A, they are able to send and receive text messages via the IM from behind the firewall. However, when the users are in site B, users are able to send out text messages but not able to receive them.
 
I noticed that when I remove "inspect sip" from site-B's global policy map, users from site-B can successfully receive text messages. I have confirmed that it is the firewall that drops the packets as I have captured the inside and outside interfaces of site-B's ASA and I can see the incoming sip "request: MESSAGE" packet on the outside interface but I do not see the packet exiting the inside interface.
 
I have cross check both firewall configurations, and I do not see anything suspicious commands relating to sip that might cause this issue. Is there any command to troubleshoot why the sip inspection is dropping the sip packets on site-B?

Cisco Firewall :: 5510 - Http Connection With Video Flow

May 4, 2011

I am using ASA 5510 and I have a specific problem with Http Connection to receive a video Flow ( RSTP protocol ) in the LAN. Some Pc users (192.168.1.133,in the log)  with ASA Lan Interface as gateway can ping the Camera but don't receveive the video flow.Some Pc users (192.168.1.116,in the log) using another gateway can ping and receive the video flow. I used Whireshark  to capture traffic between camera and Pc using the 2 gateway. I joined Logs with this message.It seems to be a problem of TCP segments on the ASA, I try to changed some TCP options but it's still the same:- Disable Force Maximum Segment Size- Enable Force TCP Connection to Linger in TIME_WAIT State for at Least 15 Second.

Cisco Firewall :: 5510 Unmatched HTTP Traffic To Symantec Public Transparent Proxy

Sep 4, 2012

I am working on a task of redirecting any unmatched http traffic to Symantec public transparent proxy through Cisco ASA. For the definition of uncatched http traffic, we have inbound squid servers for deploying IE proxy pac and redirect the http traffic to Symantec public transpraent proxy, however we can't deploy IE proxy pac to mobile device and non-support web browers.Since we have some application using IE proxy setting for direct http communication with external domains, the current symantec policy addes those domains in the exception list so that they are not redirect to Symantec public transparent proxy server.
 
-For the platform - Cisco ASA 5510 ASA 8.4(4)1

-For the solution, I have the following two nat rules

Cisco Firewall :: DNS Through ASA5510 Returns Inspect-DNS-Invalid-PAK

Dec 27, 2011

ASA5510, ASA 8.0(4), ASDM 6.1(5), this is a productino ASA with plenty of lookups working through its 3 interfaces - outside, inside, dmz.  The problem is a new use.  I've segmented a switch on the inside network with a VLAN, and have a workstation routing through the switch to the default VLAN where all other hosts on the inside network reside so far.  The ASA inside interface is the default gateway for the inside network.  My test worksttion can PING inside hosts, so the static route is OK.
 
     ASA 10.1.1.2/16     DNS Server 10.1.5.1/16
                |                                  |
------------------------------------------------------------------
                    |
               Switch 10.1.8.20/16

[code]....
                        
  But lookups fail, Wireshark says the test workstation sends, the dns server receives and responds, but the test workstation never receives.  I used the Packet Tracer tool, it gets to the last step syayin OK then finally "inspect-dns-invalid-pak".  I can't find any more there to tell just what is invlid about it.  So I'm trying to figure out global inspection.  Here's an extract from the config:
 
class-map inspection_default
match default-inspection-traffic
!
!
policy-map global_policy
class inspection_default

[code]....

Cisco Firewall :: ASA 9.X Routed - Inspect Traffic For All L3 And Transparent Contexts

May 12, 2013

We are currently looking at design models for a Multi-Tenancy solution.The firewall layer will be 2 X ASA's running 9.X to take advantage of VPN's in multiple context mode and mixed L3 and L2 contexts.
 
We will be delivering services through multiple L3 contexts (between 2 and 5 L3 contexts for services) and 1 transparent context for customers infrastructure  who will then have virtual firewalls for NAT's and VPN's etc withing their own environment.
 
I am not very experienced with IPS so my query is; if we were to get an IPS license for both ASA's how would the IPS fit in, can we use it to inspect traffic for all the L3 contexts and the transparent context?

Cisco Firewall :: 3745 / 1811 - Slow Web Connections With IP Inspect (CBAC) Turned On

I have seen this a couple of times on two different routers. One is a 3745 and another a 1811 running 12.4(15)T4 and 12.4(6)T11, respectively.
 
When we have IOS firewall running (either IP inspect or ZFW), we will experience intermittent slow HTTP connections.
 
Symptoms include page timeouts, CSS not loading and just overall slow performance. Disabling the inspection cures the issues.
