Cisco Firewall :: 5520 - Denied Due To NAT Reverse Path Failure - Asymmetric
Jul 4, 2012I am trying to lock down the VPN access on my Cisco 5520 ASA's whereby I wish not to allow users to SSH access etc on servers running on the same interface that they are VPNing into.
I did not originally configure the ASA and so I am slightly confused by some config on it. Currently when I attempt to PING a server within the same interface as the VPN network I get the following error in the logs below.
5 Jul 05 2012 09:45:15 305013 monitoringsystem Asymmetric NAT rules matched for forward and reverse flows; Connection for icmp src dmzAHdata:VPN IP dst AHdata:monitoringsystem (type 8, code 0) denied due to NAT reverse path failure
As a workaround I created a NAT exempt rule which then allowed traffic to the server in question however I wish to limit the traffic to only ICMP and when I do this in the firewall it does not take affect. Is this because of the NAT exempt rule?
Cisco Firewall :: ASA 5520 - NAT Reverse Path Failure After Upgrading From 8.4(1) To 8.4(4.1)
Jul 2, 2012After upgrading an ASA5520 from 8.4(1) to 8.4(4.1) I ran into the following trouble:
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:192.168.149.21/53 dst inside:192.168.37.123/53 [code].....
All the subnets mentioned above are connected via VPN.

Cant seem to get around this one yet. I have a remote ASA that I can VPN into. It has 2 dmz's, outside and inside interface configured.
Inside subnet is 192.168.11.0 / 24
DMZ2 is 192.168.13.0 / 24
VPN client pool is 192.168.15.0 /24
I login in fine. But have no access to the DMZ2 subnet. I get the failure listed above.
Cisco Firewall :: ASA 8.2(5) / UDP Reverse Path Check
Jun 15, 2012ASA running 8.2(5).When I enable ip spoofing on my network interfaces I see this getting logged:
Deny UDP reverse path check from 10.100.100.102 to 10.100.100.255 on interface SPECTRA-LAN
This is because interface SPECTRA-LAN (VLAN50) is the interface connected to the network with ip 10.100.100.0/24 but the interface do not have a ip address so it does not exist in the routing table I believe?However interface INTERN do also belong to network 10.100.100.0/24 which also is the management interface and the default route for hosts in network 10.100.100.0/24, but has no vlan.
1. move the management0/0 to SPECTRA-LAN and give SPECTRA-LAN ip 10.100.100.1?
2. give SPECTRA-LAN a ip address in the 10.100.100.0 range?
My routing table and interface list is:
Current available interface(s):
DATA-BACKUP Name of interface Redundant1.10
DMZ Name of interface Redundant1.900
GUEST Name of interface Redundant1.990

Cisco Firewall :: ASA 5505 Inbound TCP Connection Denied

Cisco VPN :: ASA 5505 - Reverse NAT With Only One IP Assigned To Interface
Jul 27, 2011I'm new to working with the ASA 5505 ,VPN and reverse NAT.
The basic setup is as follows. I'm trying to setup a IPsec site to site tunnel with reverse nat on the remote side.
I have as the tunnel up and it passes traffic. I have setup reverse NAT for 172.x.x.1 to translated IP 216.x.2.101 my ASA also has an IP address of 216.x.2.102.
Any connection from 172.x.x.1 to 216.x.2.1 should appear to be comming from 216.x.2.101
When I ping or telnet from 216.116.86.1 to an open port on 216.x.2.101 I get the banner from 172.x.x.1, seems like it is working.
However in my setup I'm only given a singel IP that of the NAT address 216.x.2.101, so when I remove the IP address assigned to the inside interface 216.x.2.102. all conductivity is lost.
When I set the inside interface to 216.x.2.101 and I setup a static NAT rule for 172.x.x.1 to 216.x.2.101, I get a message that says all traffic will be redirected and I will be unable to connect to the ASA.
Once thats in place, and I make any connection from 216.x.2.1 to 216.x.2.101on any port I get a connection but then it's reset, I no longer get the telent banner I was expecting.
My running config is,
ASA Version 8.2(1)

View 2 Replies View RelatedCisco Firewall :: ASA 5510 - Reverse Or Outbound NAT Redirect?
Jan 24, 2012I have the need to do an outbound NAT redirection. So what I mean is this. I have a custom program that uses SSH to port 22 from a server inside the ASA firewall. This goes out to a server on the Internet over port 22. The ISP of the SSH server told me that they changed their SSH port from 22 to 2102. So instead of changing the custom code on the developed application on the server... I thought it would be easier to do a OUTBOUND NAT redirection for the ASA to see port 22 from the server and redirect it OUTBOUND to port 2102.
so for example:
The server is at 192.168.0.2 and it uses a program to initiate SSH traffic to 205.246.1.1. The server sends to port 22 but I need it automatically changed on the firewall to port 2201 at 205.246.1.1.
It is a Cisco ASA 5510. The server at 192.168.0.2 does have a fixed IP address on the outside with INBOUND NAT for things like port 25 (mail) traffic etc. Lets pretend that was at 64.18.23.60.
Cisco Firewall :: Reverse Port Redirection With ASA 5505?
May 16, 2013We have a singe IP Address in the Internet and want to forward SMTP traffic that hits our ASA Outside Interace to the internal Mailserver.And we like to forward Http Traffic to our Webserver.
Example.
212.23.23.23 Port 25 -> 192.168.1.100 Port 25
212.23.23.23 Port 80 -> 192 168.1.200 Port 80
How do i acomplish that. Which NAT rules do in need?
Error Occurred While Connecting To Network Path Was Not Found
Sep 3, 2012I am running a Windows 7 Professional 32 bit as my office computer. About 3 PCs in the office are connected to the office server through wireless connection (including mine), and another 3 are connected through a wired connection. My connection to the server doesn't work at times. I get an error message that "An error occurred while connecting to . The network path was not found." The other PCs using the network have no problem connecting to the server. Also, the internet connection is shared from the server and I have no trouble with it. The problem is only with accessing the shared folder on the server.

Under "Specifying Hosts and Networks / Remote Network" i use not the external ip of remote Site, i use the internal networks ( 10.0.1.0 and 10.0.2.0 ). I need connetion to two remote internal networks ( from 10.0.0.0 to 10.0.1.0 and 10.0.2.0 ). The Tunnel (Phase1 and Phase 2) comes up when i ping a host of the second (10.0.2.x) remote network, but a ping is not possible.

Sharing :: Error Code - 0x80070035 Network Path Not Found
Feb 12, 2011On my home LAN I have computers running Ubuntu 10.10, Win XP, Win7 32 bit and Win 7 64 bit, as well as an Iomega Home Network Media Drive. I can share files and folders between Ubuntu and XP without problem. I can CRUD (Create, Read, Update, Delete) to the Iomega device from all the computers. I can share folders when using the 64-bit Win 7 computer that are located on the XP computer.
I can see the 'users/Public' folder on the 64bit Win 7 computer from the XP computer (but that folder being empty, this access is not a lot of use - a secondary probelm). I cannot see my 'user name' files/folders on the Win 7 computer from the XP computer
From Computer, Network on the Win 7 computer I can see the Ubuntu computer by name (approximately - it's all in upper case, which is not correct as far as Ubuntu is concerned).
I cannot access files on the Ubuntu computer via its name - I receive the usual 'network path not found' error, inviting me to check the spelling of the computer, which I can see is wrong, but which I can find no way to correct.
If I try to access the Ubuntu computer by IP address, then I am presented with an 'Enter Network Password' panel. I have never allocated a network password, so I have no idea what user name or password to enter here. If I enter my valid account name forthe Win 7 machine, along with its valid password, then a Logon failure is reported: 'unknown user name or bad password'. If I use the single valid user name and password for the target Ubuntu computer, I receive the same failure message. I thought I had set the same user name on both computers (I certainly have the same password), but for reasons best known to Bill Gates, the username on the Win 7 computer has been initially capitalised, making it absolutely not the same as any valid user name on the Ubuntu computer.
So, in short, I can find no way to access the Ubuntu computer from Win 7. Further more the Ubuntu computer cannot see the Win 7 computer in the windows network at all.
I have the same internet security software (Comodo) running on all Windows computers. It is enabled on the XP computer. It is disabled on the Win 7 computer - but with no effect on the failure to connect.

Why is the firewall interjecting itself and causing these issues?

May 6, 2013I am new to ASA's and have just configured my 5505 out the box with an outside (10.10.1.7) + inside (192.168.1.1) IP & NAT. The ASA has got a default route to another router (default geteway) thats connected to the internet. I have it connected this way so I can play and **** around with the ASA. My problem is when I try and ping a host on the ASA inside network (192.168.1.0/24) from the outside (10.10.1.0/24) I'm getting the following error: 5May 07 201316:38:36305013192.168.1.6Asymmetric NAT rules matched for forward and reverse flows; Connection for icmp src outside:10.10.1.22 dst inside:192.168.1.6 (type 8, code 0) denied due to NAT reverse path failure The recommendation from the syslog details is:"When not on the same interface as the host using NAT, use the mapped address instead of the actual address to connect to the host.

View 2 Replies View RelatedCisco Firewall :: ASA 5510 Q.264 Video From Axis Outdoor Camera Denied
Apr 9, 2012I have a customer with a Cisco ASA 5510 firewall, an inside network containing a Genetec video recording server, and cameras installed on broadband modems throughout the area (each with a public IP). They've recently purchased Axis Q6034-E cameras that use H.264 to stream back to the video recording server. The camera has a view mode where you can watch it through H.264 or Motion JPEG. The view with M-JPEG works, but when I switch to H.264 the video stream is denied. We have allowed RTSP, RTP, and HTTP (it's setup with only http, not 443)traffic from the camera address on the cable company public network but are still being denied the video stream. The recording software requires that the feed come from the H.264 feed, so the motion jpeg does not fix the underlying issue of being able to record.
We know it's the firewall because if we install the camera on the inside network, the video feed in H.264 works to the recorder.
How to enable something special on the firewall to allow traffic through from the device?

Linksys Wireless Router :: E4200v2 - Error Code 0x80070035 Network Path Not Found
Jun 15, 2012I thought I would leave a message on a problem. I did two chats to the support desk and this was not brought up and it is obvious. I just installed the 4200v2 as a replacement for a NetGear. I bought for the n performance and the USB for a shared disk/media file server. I connected a640G Western Digital My Book to the USB. I was able to see the drive in the asp interface of the router, but I kept getting the "error code: 0x80070035 network path not found" message. My computer is a 6 month old HP with Windows 7 running Bitdefender Internet. I found I could get to the drive from my wife's Toshiba (only used for browsing, so minimal security), so I thought it was a firewall issue (also what Cisco said). After doing some Internet mining, I found that the issue is the Netbios setting in IPv4. My PC had the setting Default, which requires the DHCP server to provide the setting and apparently this was not set by the 4200. Without Netbios the disk cannot be mapped. Changing this to NetBios "enabled" solved the problem. This can be reached by going into the Control panel:Network and Sharing Center. Click on the connection (either local area or wireless), then open the properties, click on the TCPv4, Click properties, then advanced. Go to the Win tab and select Netbios enabled.

May 2, 2012I am running ASA 5505 release 8.2(4) using a clientless SSL vpn to connect my assessors to the server via RDP to a Terminal server. Everything was working fine until last week when we had a Internet outage. During the outage some of the assessors claimed to have accepted a Cisco add-on to get into the site. once the internet came backup they could not connect to the terminal servers - what would happen is they would click on the link - say OK to connect the clipboard and the screen would pause for a few seconds then right back to the select options page.
they can get to other servers (non-terminal servers) but not to the ones they need. I can recreate the issue by waiting a REALLY long time before replying to a prompt to install an cisco add-on. I have users that can connect and others than can not. Also this only seems to affect Internet Explorer 8 and 9 does not affect Firefox
