Cisco Firewall :: Getting HTTP Behind ASA 5520 (Ver 8.2)

Mar 12, 2013

Two days ago, we changed our old 525 with asa 5520 ( ver 8.2 ). Configuration is the same, except the version. It even retains the same global interface and static public ip address as the old device.All worked well during that period.Yesterday, one of the http applications , not tested other day, was found not to be working. To test, we switched back to the old 525 , however nothing was working when we did that.Does the static statement which actually does the translation for this application carry any arp problems or so.how can i check this problem.

Cisco VPN :: Connection For Accessing Server On HTTP Port Only - ASA 5520

Mar 10, 2013

We have ASA5520 and we want to configure a VPN IPSEC profile so that a partner of ours can access only a server and only on HTTP port.I've tried configuring split tunneling with an Extended ACL but probably I'm missing something. I just configured the ACL so that it included any source to our server's IP on HTTP port but when testing, it didn't work.
 
However, if I configure a Standard ACL on the split tunneling I can access the server and all the services it provides.Do you know if I'm missing anything on the Extended ACL configuration?
 
Should I configure this any other way?

Cisco Firewall :: FTP And HTTP Access Using PPPoE On ASA 5505

Feb 23, 2011

configure my ASA 5505. It is setup using PPPoE. What I want to do is this:
 
I have one of my IP addresses (99.23.119.78) setup for ftp using the ftp protocol to our internal IP address 192.168.1.3. What I need is to also allow for HTTP access but not just that, I need it to forward the http port to port 9000 because the web interface requires port 9000 for customer access. Previously on our old firewall customers were able to access the web interface by browsing to [URL]. I would like to not have to not require the port in the URL.
 
In addition, I would like to be able to setup a different IP address in our range (99.23.119.73) to be setup for http access using the standard port 80 for the same internal IP address (192.168.1.3). This URL will allow us to access the administration web interface for the FTP server.
 
Here is my current config:

Cisco Firewall :: 3700 - ASA Drops HTTP Packets

Mar 13, 2013

My config:
 
Windows 7 host 
MS Loopback Adapter with ICS
GNS3 
ASA 8.42 with ASDM 6.4 
Vmware Workstation 7 with Windows XP SP3 vm
 
All are working like a charm, from my virtual XP machine I can ping every site, e.g. www.google.com which replies nice with it's ip-address.
 
However, I cannot reach ANY website
 
When I connect through a Cisco 3700 router the webbrowser works perfect, so it must be something in the ASA configuration (I presume )
 
I've tried about all possible Access Rules, but still nothing.

Cisco Firewall :: ASA5510 Need To Unblock Http Radio Stations

Apr 1, 2011

I have an ASA5510 with CSC Module which is inspecting HTTP traffic. We need to be able to use http radio stations. Some radio stations work but some don't work. I excluded my computer ip address from the CSC filtering but i am still unable use certain radio stations. I thought since my computer is excluded from the CSC filtering and some radio stations don't work that it must be the firewall that is blocking the traffic. I removed the rtsp inspection and it won't work.

Cisco Firewall :: Redirect Http / Https To Port 8080 PIX 6.3?

Feb 27, 2013

I need to redirect all http and https traffic from one source in a dmz network, to port tcp/8080 on a proxy server on the inside network.
 
The source device doesn't handle proxying very well, so i've been advised to redirect the tcp/80 and tcp/443 ports to tcp/8080 as it passes through the firewall.
 
Scenario is thus:
PIX 515E 6.3 (5)
DMZ server: 172.31.255.250 (Real IP), 10.44.181.236 (NAT IP)
Inside Proxy server: 10.44.132.28 (Real IP), 172.31.255.110 (NAT IP)
 
I've configured a static NAT redirect using the following command: static (inside,dmz) tcp 172.31.255.110 www 10.44.132.28 8080 netmask 255.255.255.255 0 0
 
When I try to add the next command of: static (inside,dmz) tcp 172.31.255.110 443 10.44.132.28 8080 netmask 255.255.255.255 0 0
 
I get the following error: ERROR: duplicate of existing static
 
Is there a work around for this at all or am I stuck with the limitations of the software?

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}

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}

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 :: 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 :: PIX 515E Slow Http From Inside To Dmz Network

Oct 16, 2012

I have a PIX 515E V7.0.4 and I'm having trouble with http access between the inside interface and a DMZ zone I have.  I have a web server setup in the DMZ with an web interface to upload/download files.  I can connect to this interface from a workstation in the inside network but when I try to download a file it is incredibly slow.  If I upload a file there are no speed issues.  If I connect using an https connection then both upload and downloads are at speeds I would expect.
 
I have disabled http inspect but this didn't improve the speed connection.
 
Other http communications from inside to outside do not have any speed issues in either direction.

I'm looking fot a way to do static URL blocking with ASA and when the URL is blocked present a "Web Page" to the user saying that it's been blocked.

So, i was wondering if i can use the http parameter "spoof server string" to replace the original URL sent by the user for another URL that points to an internal web server holding a basic page saying "Your URL request has been blocked".
 
The point is to have a way to tell users that the page they are trying to browse is blocked by a policy.

Cisco Firewall :: ASA5510 - Redirect HTTP Traffic To Internal Proxy?

Feb 13, 2011

I am using ASA5510 and i want to know if it is possible to redirect http traffic to an internal proxy software. I explain : PC from the LAN use a internal proxy in their IE browser but some other PC doesn't use it.They are directy connected to the Internet using the Public IP from the WAN interface ( via NAT). Can we redirected this HTTP Traffic from the WAN interface to the Proxy in the LAN ?
 
Http Traffic will be routed like that : PC ->  WAN interface -> Proxy -> WAN interface -> Internet In fact,can we create a rule saying : All http traffic which doesn"t come from the IP Proxy must be redirected toward proxy.

Cisco Firewall :: 1811 / Zone Based FW With Non-standard HTTP Port

Apr 4, 2011

We are testing a Zone Based FW config since 1month, everything run smooth but we're having problem ( big slow speed access ) when a user try to reach a website on a non-standard port ( 8080 in that case ). All the trafic stay in our LAN, using a IPSEC/EZVPN connection between the 2 sites.As soon as I have disabled the Zone Based FW, the speed was much better.
 
I'm sure I'm missing a parameter to fix that problem but I tried many different options and I didn't find anything yet. All the routers are Cisco 1811 running adv IP Services 15.1.2.T1 IOS.A port-map has been created to map the port 8080 to the HTTP protocol for the inspection.The PC will have an IP address in the 10.2.2.x/24 and will access a server on 10.2.3.x/24, both devices are part of the zone private in each site/LAN.All the access between sites are managed by an ASA; the IPSEC/EZVPN peer.Little summary, it's gonna be something like : SiteA with a PC on private zone then on public zone for the EZVPN to SiteB on public zone and then private zone to access the server in the LAN.

Cisco Firewall :: ASA 5505 - Redirecting Http And Https Traffic To Proxy Server

I have an ASA 5505 that I am using to connect my contractors to via an inside interface, the outside interface is my private LAN. I have setup on our corporate Proxy server to allow traffic from my outside interface of my  ASA to go to the internet without credentials BUT log internet activity. The question is I want to know if the ASA can send that http & https traffic to my proxy server and all other traffic to my default route? I want to be able to send all internet traffic to my proxy server. This will avoid me asking the contractors to place proxy credentials in their browsers.
