Cisco Firewall :: ASA 5505 How To Map SSH From Outside Network Range To Internal
Feb 21, 2013I have a Cisco ASA 5505 (version above) and I have someone that needs to SSH into a box behind the ASA. I'm having a few issues trying to configure this access-list and NAT. I've tried many combinations and clearly my IOS is not as good as I thought. What commands should I enter to accomplish mapping SSH from an outside network range to an internal host ?

Oct 27, 2011For a customer I have configured a new ASA 5505 firewall with 8.42 software. I had to build 3 ipsec tunnels to different locations and firewalls. All tunnels are working except one. I have to translate the inside network 1 to 1 to a different private range before it is sent over the tunnel. Each host from network 192.168.133.0 /24 has to be translated to a 192.168.112.0 /24 host and then sent over the tunnel. (e.g. 192.168.133.22 translated to 192.168.112.22)

Cisco Firewall :: ASA 5550 - Cannot Ping SITE 1 PIX From Internal IP
Oct 15, 2012We have two networks HQ and Site1 and for some reason we can’t ping the inside IP for Site1 PIX device. We have site-site-VPN set up between the two and everything works fine except we can’t ping the Site1 PIX from internal IP. However, I can ASDM/SSH in from HQ to the external IP of the Site1 PIX.
HQ is using an ASA 5550 (172.1.0.1) PC from HQ (172.1.64.x) Site1 is using a PIX-515E (172.2.0.1) PC from Site1 (172.2.64.x)
Ping from HQ PC to Site1 PC (172.1.64.x to 172.2.64.x) works fine
Ping from Site1 PC to HQ PC (172.2.64.x to 172.1.64.x) works fine
[code]...
ASDM/SSH from any HQ PC to Site1 PIX internal IP (172.1.64.x to 172.2.0.1) doesn’t work
ASDM/SSH from any HQ PC to Site1 PIX external IP (172.1.64.x to Site1 external IP) works fine
Everything was working fine until we recently changed the outside IP address for Site1 because we switch to a different ISP. Nothing changed on the HQ ASA or Site1 PIX other than the outside IP address on Site1 PIX. I did rebuild the site-to-site VPN tunnel between Site1 and HQ.

Feb 18, 2013I am new to Cisco ASA and have been configuring my new firewall but one thing have been bothering. I cannot get internal networks and routing between them to work as I would like to. Goal is to set four networks and control access with ACL:s between those.
1. Outside
2. DMZ
3. ServerNet1
4. Inside
ASA version is 9.1 and i have been reading on two different ways on handling IP routing with this. NAT Exempt and not configuring NAT at all and letting normal IP routing to handle internal networks. No matter how I configure, with or without NAT I cannot get access from inside network to DMZ or from ServerNet1 to DMZ. Strange thing is that I can access services from DMZ to Inside and ServerNet1 if access list allows it. For instance DNS server is on Inside network and DMZ works great using it. [code]
Cisco Firewall :: Can't Access Internal Servers From Behind ASA 5505
Apr 3, 2013I am having some trouble accessing some backup Email (Outlook Web Access) and Citrix servers located behind an ASA 5505 firewall at a remote datacentre. Simply put, when I go to the specific URL (e.g. [URL]) I do not arrive at the splash page, I just get a message saying that the server took too long to respond in the web browser. I'm wondering whether I have missed something on the configuration or the firewall itself is not letting my requests through. The remote servers are located at a remote Disaster Recovery site and use the subnet 192.168.4.0/24. I am at head office which is connected to the DR site via a VPN using 192.168.1.0/24.

Cisco Firewall :: Internal DNS Server Entry ASA-5505
Jan 12, 2011I have a client in a workgroup environment. They are a small company with perhaps twenty systems. Their infrastructure consists of a Dell Switch, a Cisco ASA-5505 which hands out the DHCP and a router. And that's that.They have been using an external IP as their DNS Server to get out to the Web. However, they now want to add an internal Linux-based DNS server.In looking through the ASA-5505 today I noticed a field for DNS enteries. Is this where the IP for this new internal DNS Server (in the secondary DNS field) would go?If so, would it be necessary to reboot the ASA-5505 for this change to take effect?
View 12 Replies View RelatedCisco Firewall :: ASA 5505 Connecting 2 Internal Networks?
Nov 7, 2012We recently changed locations and acquired a new circuit from our provider. They also connected our remote branch office to our main office through MPLS. Now, as I understand it, the branch office basically connects back to the main office through our providers network (MPLS). We have a new router at the branch office which has a gateway of 192.168.1.225. The clients in that office have IP's of 192.168.1.96 - 100, using the gateway of 192.168.1.225.
The main office network is 192.168.0.0 (Gateway of 192.168.0.1)
At this end (Main office), I also have a new Cisco 2900 provided by the ISP, with port 0/0 for the outside connection (connected to the 0 port on my ASA 5505). The ASA's port 1 obviously running into my network hub. The provider tells me that port 0/1 on the 2900 is or should be used to connect the branch office back to here and has an IP of 192.168.0.225, as that's how the provider provisioned it. So, I plug that into the ASA's Ethernet port 0/2. And I'm assuming they have a route setup either on the 2900 or the router in the branch office so that 192.168.1.225 can reach me here at 192.168.0.0.
There is already a static route setup on the ASA: (192.168.1.0 255.255.255.255 192.168.0.225 1). As soon as I plug in the cable, the IP phones at the branch office work, but they can't access the internet or any resources in the main office. My questions are:
1. Shouldn't I be able to just go straight from the 0/1 port on the Cisco 2900 to my hub. At first I was plugging right into the ASA, but I don't think I need to do that, why go from the branch office through my ASA to access resources and then back out the ASA for internet. If they're already coming from 192.168.1.225, through the MPLS network, then they should go right to my network and then back out the ASA.
2. They have to route through the ASA first, in which case, do I need to setup another VLAN for that branch network in conjunction with a static route? I can ping the router and hosts in the branch office through the ASA only!
Below is the running sanitized config:

Cisco Firewall :: ASA 5505 8.4(2) Allow User To Access Internal Www Server?
Aug 2, 2011I tried the solution posted at [URL] however it did not work on my ASA5505 8.4(2). I thought that it may be because I only have a single public address so the web server is responding to port forwarding through the one public IP already. looking in ASDM it appears to indicate that a configured access list is blocking the server from responding to the internal hosts.
object network Private_IP
host 192.168.1.15
object network Public_IP
host 1.1.1.1
object-group network internal_net
[code]....
Can I fix an access list (or something) to make this work or am I wishing for too much with only one public IP? This worked by default on my Netgear firewall.

May 30, 2013I have an old ASA 5505, and I'm having some trouble with Nat Hairpinning. I've done this with other firewalls before and I am having no luck now. I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.

Cisco Firewall :: ASA 5505 Intermittent Denies From Internal Workstations

Cisco Firewall :: 5505 ASDM Location Is Using Same IP As Internal Server
Oct 27, 2011I have a server that I need to open up some ports on to allow access to the new internal Sharepoint server we're setting up. I've been having some issues getting the ports open like once I put the commands in and save them that server suddenly stops allowing outbound traffic. After looking at a few things I noticed while I was looking at the config file that the ASDM location is showing 2 IP's, both are the same as the server I'm trying to open ports for one being the private IP and the other is the public IP I'm trying to use. Is this the reason I'm having problems when I try to open those ports to my server? Do I need to use both a different private and public IP for this server so I can get my ports to work? The programmers selected these IP's so if I need to change them I'll let them know in case they need to make changes for the Sharepoint setup. This is on an ASA 5505.

Dec 23, 2011Currently I have an ASA setup as a Firewall with 1 outside interface and 2 inside interfaces. Initially, the Guest interface was setup to receive DHCP from the ASA and everything was working. I'm adding router and a server for the guest interface and what I'm trying to accomplish now is the following: ASA 5505 > Airport Extreme with a public static IP (69.xx.xx.6), handling DHCP and NAT > Mac Server as DNS Server.Right now, when I connect to my Airport Extreme with any computer, I don't have internet. I don't understand what's wrong. My DNS Server has a reserved IP address: 192.168.226.2 and it's pointing to itself and forwarding the ISP DNS servers, the Airport Extreme is handling the DNS Server IP and the ISP DNS Server IP but I can't connect to the internet from the server.

Cisco Firewall :: ASA 5505 - Discarded Incoming Packets On Internal-Data0/1
Apr 4, 2013How to best troubleshoot some errors I'm seeing on the internal interfaces of my ASA 5505. This is similar to the question at [URL], but the details are different enough that I felt it justified a new discussion.
I have an ASA 5505, running version 8.2(2), 256MB RAM. From time to time (on the order of once a week) our monitoring alerts us that both Internal-Data0/0 and Internal-Data0/1 are experiencing an unusual amount of inbound packets which were discarded with errors, up to 2.3 per second as of this post. Here is what I hope relevant output from my device:
asa# show interface ip brief
Interface IP-Address OK? Method Status Protocol
Internal-Data0/0 unassigned YES unset up up
Internal-Data0/1 unassigned YES unset up up
Vlan1 10.x.x.x YES CONFIG up up
Vlan2 32.32.32.32 YES CONFIG up up
[code]....
1. My understanding is that Internal-Data0/0 is an internal bus that connects to modules like the 4GE. I don't have any modules installed at all, as you can tell. Therefore, what is this bus doing?
2. For that matter, what is Internal-Data0/1 doing? What does it connect to?
3. I'm guessing that due to the input errors and overruns reported for both of these interfaces, it's a buffering issue. Since these are input errors, does this mean that traffic destined to this bus for forwarding is being dropped because the bus itself is running out of buffer memory? How would I see (and subsequently monitor) the buffer memory for these interfaces? Once I am able to see it, what sort of tools can I use to determine what is causing this?
Cisco VPN :: 5505 - Logged In VPN Can't Access DMZ From Internal Network
Apr 9, 2012What I got is a 5505 ASA firewall and I'm connected to it via VPN. I'm pulling an 192.168.169.x address because that's what we set their company's internet LAN to. Which is what we want. What I can't do while I'm VPN'd in is ping from the internet network to the DMZ, and the same when I try and ping from the DMZ to the internal network.
The DMZ is on a 196.0.0.x network.The internet network is 192.168.169.x network.
I don't need them to have internet access on the DMZ I just want to be able to access it from the internal network. What is going on is we need them to be able to VPN into the DMZ and access their equipment. At this point it would just make me happy to be able to ping from the internal network to the DMZ and I can figure it out from there I've setup rules and applied them and when I wasn't having success I referred back to defaults. Right now the rules are set at default, any thing in and anything out, on both internal and DMZ. I'm using a VPN client and going through Cisco ASDM Launcher to setup the rules and static routes, I haven't done anything with the command line. All the research I've done everyone does it command line, I find it easier to do it GUI. This is my first time working with an ASA firewall.

Cisco Switching/Routing :: 5505 Can't Connect To Public NAT Address From Internal Network
Dec 19, 2011I have an ASA 5505 configured with internal network, a DMZ, and a VPN on seperate subnets. The implicit rules allow my internal client computers to connect to the web servers on the DMZ IP, but I can not connect to the public NAT address from the internal network. I have a DNS server on my internal network and it does resolve to the public IP correctly. NAT seems to be working correctly because if I go outside the network and connect to the public IP or qualified name then I can get to everything correctly. I do not see any messages in the Cisco logs and the packet trace tool shows the route of http from an internal IP adddress to the external (NATed) address is allowed.
Specifically, I can go to http://192.168.1.121 from the internal (192.168.0/24) network, but I can not go to http://72.22.214.121 (the NAT address) from the internal network. If I am outside my cisco then I can go to http://72.22.214.121 easily. [code]
