Cisco Firewall :: ASA 8.4 NAT Internet IP To Private
Mar 22, 2013
I have a server with IP address 10.10.10.10/24. I have two ISPs and their public IP address subnets are 1.1.1.0/25 and 2.2.2.0/25. The gateways are ASA 8.0 and ASA 8.4.I am getting rid of the 1.1.1.0/25 ISP. However I will need the Internet users to be able to access the server via both ISPs at the same time.The only way I can think of is to do policy based dynamic PAT so the Internet user IPs will be translated into an internal IP. Idealy, users connecting on 1.1.1.10 will be PAT to 10.1.1.10 and users connecting to 2.2.2.10 will be PAT to 10.2.2.10. When the server responds to them, it will then route to the correct ASA..
I am trying to provide internet access to public and private SSID's on Cisco AP541n using VLAN's connected directly to ASA5505. VLAN1 is inside interface (private) and VLAN12 is wlan interface (public SSID). The AP541n is plugged into switch port 0/7 on an ASA 5505.Port 0/7 is configured as trunk mode. I have internet access when connected to private SSID but no internet access when connected to public SSID. why I can't access internet on public SSID?

We have some Cisco 2911's that we are configuring 2 VPN's ( second is for redundancy) We are pretty confident on the failover VPN setup using SLA monitoring.
One thing we are stuck on is the redundant VPN will be setup over a 3G connection provided by verizon. Verizon issues a Private IP ( 192.168.100.X) the far end device terminating the VPN has a public ip of 183.172.22.XX , what kind of NAT translation do I need to make this work ? Also does Cisco have any good configuration examples for VPN Failover setups for Cisco 2911's?
I am now using ASA 5510 as a firewall device.I have configured 3 interfaces ethernet 0/0,ethernet 0/1,ethernet 0/2 as Wan interface, DMZ interface and Internal Lan interface. Internet is working fine from LAN as well as DMZ.The WAN interface use the Public Point 2 point IP(/30) Provided by the ISP and another pool of Public Ip is also provided by the ISP (/28). Now I want to Map the /28 IP to some servers in DMZ . DMZ servers currently have 192.168.101.0/27 private IP . Now the problem is how to Map the Public IP to those Private IP in DMZ servers.
We have the setup as shown above, our requirement is to access mail server via ports smtp and pop3.But as the mailserver is hosted at internet users at site were not able to aceess. we need to nat a intranet ip with mail server ip and mail server ip back to intranet ip and provide the access.We use ASA 5510 firewall.
I'm having an issue with out going sip traffic showing my private IP in the header instead of the public IP. I have a cisco asa 5510 and everyone seems to think the issue resides on the firewall.
How to setup this Nat on an ASA 5520 running 8.3.2 code? I know this must be possible as I can do the same thing on my Check Point with no issues. I need to Nat two dmz mail servers to one public mx record. I will have an F5 to load balance inbound and outbound traffic from the mail servers. So I need to Nat two private IP’s to one public.
I have the following situation. A colleagues installed a spam block (Norton something) and he put two ip's on itsinterfaces. 192.168.2.20 and 192.68.2.21. One will be used to receive and one to send mail but both on port 25. They use a sinlge real IP 175.75.67.32. I am using a 5540 ASA with 8.2 IOS.
I am pretty sure this cannot happen but i got some advice to NAT the outgoing IP/Port and then PAT the incoming port to both IP's and it will work. I tried to do it with no success. I know that ASA 8.4 changes everything in NAT/PAT but is there any way with the newer OS my setup can work or not?
Currently a network consists of two subnets, one subnet is behind a ASA and the other behind a PIX, both connecting to the ISP's routers. If the PIX is retired, is it possible to create/consolidate the two networks protected by the ASA5510 with the default gateway being the ISP?
How can two private networks be protected by the ASA5510? One conceptual way is to create the VLANS on a layer 3 switch, on the "inside" interface of the ASA. In this senario what would the "inside" network's IP address? If the above is possible, how would natting occur?
Is there an efficient configuration to protect two networks protected by the 5510, other than creating a DMZ?
Is it possible to create two private networks with same level of security, 100 on a three network interface connections?
I'm trying to achieve a site-to-site ipsec tunnel to a Cisco ASA 5520. Most examples feature the ASA with a public interface that terminates the tuennel and a private network on another interface that the tunnel interacts with. Where my scenario differs is that the interface that accepts the tunnel is part of a public /29 network where I want the remaining hosts on that subnet to be able to route thrugh to the other end of the tunnel. My tunnel gets established, but any attempts to route via the IP assigned to that one interface result in the ASA rejecting traffic. If so, what configuration options should I consider?
I am having a spot of bother with a Cisco PIX515, I have posted the current running config below, now I am no cisco expert by any means although I can do basic stuff with them, now I am having trouble with traffic sent from the outside to address: 10.75.32.25 it just doesn't appear to be going anywhere.
Now this firewall is deep inside a private network, with an upstream firewall that we don't manage. I have spoken to the people that look after that firewall and they say they they have traffic routing to 10.75.32.21 and 10.75.32.25 and thats it (although there is a website that runs from the server 172.16.102.5 which (if my understanding is correct) gets traffic via 10.75.32.23.

We currently have a HP blade platform which has two Cisco CBS30X0 switches built into it running Version 12.2(55)SE. These are connected to two Cisco C2960 aggregation switches running Version 12.2(44)SE6. According to this article I need to upgrade these to 12.2(25)FX: url...
1.)This will according to that article only allow me to create edge ports on them, is this a hardware limitation or am I just not finding what firmware I need to upgrade them to, in order to allow the creation of community VLANs? We have these aggregation switches conncted directly to multiple types of firewalls which take care of each of our clients networks including internet access etc. We are wasting many VLANs and IP addresses with our current setup so I am hoping to move over to using private VLANs. The setup of the private VLANs looks simple enough.
2.)When the private VLAN's try to communicate, all info will be sent directly to the layer 3 device I gather, which will not need to know anything about the private VLANs?
I have purchased a subnet of 8 private IP addresses from my ISP. 109.x.x.128/29.The ISP has placed a juniper router within our data centre which is routing purely from 109.x.x.206/30 to 109.x.x.128/29 with the ip of fa0/1 set to .129.
I have linked a cisco 5505 to fa0/1 of the juniper from fa0/0 and configured its IP to .130. I have configured NAT to translate our client pool 192.168.16.x /24 address' to the internet.
Is it possible for the 5505 to route / map my remaing private IP addresses through its external port? I have tried creating a seperate VLAN for a DMZ for our servers to sit within but am returned with a subnetting error as VLAN for my external port is all ready configured within the same subnet.
I'm setting up a Cisco ASA 5510.I did the setup for my public and private interface.From the management software I can ping any outside domain using my public interface, but when I try to do that from my private interface I cannot.Also for some reason my ip phone connected to the private interface work (I'm able to make and receive call), but any computer that I connect to the private interface I cannot access the internet.
In my office we have a private LAN of 10.0.0.0 having no access to internet/broadband. To connect to internet, we do it by using broadbandconnection/Modem from MTNL. Both things require a separate NIC card. My query is "Can I use my BroadBand Modem to connect to internal LAN". I have heard this is possible by some suitable changes in Current Control Set in Windows
the site has a private wireless network for which I pay a yearly access fee. This gives me a code I can use to gain access each time I connect. We used to be able to have all our family's laptops, etc., connected at the same time using this code, but the site has recently changed the configuration so that we can't do this. Is there any way we can share the connection made by one computer so that we can all access the Internet at the same time? The site is in a remote location that gets poor mobile data coverage and landlines are not an option. The yearly fee is already high, so I can't afford to pay for multiple subscriptions.
What I'm trying to do is create a private network for local file sharing but also have internet access. There is a WRT54G router connected to a satellite modem in a separate building, just barely close enough to connect from my laptop, which is what sparked my original idea to use my WRT54GL as an access point.
Can the N150 be set up so that it just runs a private network - not connect to the internet? The auto-setup doesn't seem to work without a modem attached to it and I don't want it to be hooked up to the outside world, just a few computers and a NAS device on a private net.
Why is it that my netbook doesn't have internet access on my Private Network? But when I connect it to my Guest Network, it does have an internet access. It's the only device I have that doesn't have internet access on my Private Network. The rest are working. I tried all the possible options to connect a device but still the problem exist.
We have Cisco ASA 5505 with ASDM 5.2 We have one Proxy server in our Local Lab and pointed to Hosted service(Simple Signal)issue is, When our proxy server send register to hosted server, ASA change private IP and post with outside IP and src port as 1063 every time.
Here is debug log on real time monitoring.

We are planning to split the Private servers from the DMZ Servers and configure an additional Interface and segment for this purpose.
Private Servers Segment: 192.168.4.0/24 (there is no DHCP all servers' IPs are statically configured) DMZ Segment: 192.168.3.0/24 (This is a future deployment) LAN Segment: 172.17.0.0/16
Both, Private Servers and DMZ Servers are in a collocation as well as the ASA5520. There are multiple Branch offices that uses subnets within the 172.17.0.0/16 Network and they are connected to the ASA5520 via Metro-E.
I do not know if this is possible but what I want to do is this:
In order to avoid the change of internal DNS records I want to mask the DMZ servers with a Private Server IP when a Private server or LAN host wants to access it like this:
The FTP server in the DMZ has the IP address: 192.168.3.100. But when a PC from the LAN wants to reach the FTP server it should points to its old IP: 192.168.4.100. This way the PC sends a packet to the ftp.corporate.net (192.168.4.100) the ASA recieves the packet and translate it to the (192.168.3.100) and send it out through the DMZ Interface.
Also if the Private Servers wants to reach the same FTP the ASA will act like a proxy-ARP and send the paquet to the DMZ by means of the translation of the IP.
my private ip add is been hacked by someone, I have chk from various sites but the host name is unavailable so pls let me know how to get the host name of that pc & how can i get my ip 10.62.11.33 back to my org
how the address stops at 31 in the second octet. I'm not even completely sure how it starts at 16 for the first address (172.16.0.0). are we dealing with subnets?
Is it possible to use 1 private IP through VPN and same private IP mapped with Public IP? For example 192.168.0.1 is configured in VPN tunnel. i m able to ssh on both ends. ( VPN phase 1 and phase 2 gets completed)But when i map 192.168.0.1 with some public IP problem starts. when i try ssh i see public IP in my destination firewall logs. IPSEC: Received an ESP packet xx.xx.xx.xx "mapped public IP". The decapsulated inner packet doesn't match the negotiated policy in the SA, The packet specifies its destination as
I'm looking to put together a solution for a customer that wants to "bridge" between their current office and a new office space they have rented. I know how to set up a site-to-site VPN between two sites with different private IP ranges. For example, site A is 192.168.1.0/24 and site B is 192.168.2.0/24. But is it possible to make both sites appear as a single IP block? This way, systems could be moved one by one without renumbering.I am guessing there might be a way to tunnel the layer 2 traffic and make it work, but I am concerned about broadcast services being broken. I am using non-cisco platforms so I am just looking for pointers on the protocols that might be used so I can do further research.
i recently get high speed link for my compagny to replace the old frame realy.the internet service provider gave me a non routable range to set on my asa like this : [code]then the ISP tell my public ip wan range was x4.23.209.166/29.i made this kind of configuration works when i put a cisco routeur in befor the cisco asa like this: [code] it is possible to make this works on cisco asa 5510 without putting a router in front ?if it works problem can happen to establishing vpn from the outside interface having a private ip ?
we have one OC-24 private line between our data centers. we are looking to get best throughput but we get max. avg throughput of 300Mbps with peaks of 800Mbps throughput. i.e. we transfered 2TB of data over this link and we got average throughput of 300Mbps with peaks of 800Mbps.
we should at least be getting 800Mbps throughput since we have OC-24 (1244Mbps) private line. we contacted our ISP but they said there isn't any problem in private line from ISP side. what can we do to increase average throughput?
I have my SSL server certficate on my old acs 3.3.along with private key file , How i can export this private file with .pem extension from windows 2000 server , This private key file is not identified under certificate mmc console , Because my acs application is being installed on a separate hardisk partition under D drive .
file path : d:Certificatesh02cacsw02.pem
how i can export this.pem from that particular folder
I have a router, networking 2 computers. One of them I wish to set to "ad-hoc" I do not want it accessing the internet.
So, a "wired ad-hoc".
The best discriptsion I have is on a Vista or 7 machine you have the Network map I want to disconect the computer from the internet, and leave it connected to the network.
I have a IBM T23 laptop that I have reformatted and am trying to log onto my wireless internet via a linksys pcmcia card which When I try to connect it tells me I have private IP address and I am not sure how I can reconfig so that I can connect via my router to the internet.
I have two Win XP machines. One is connected to the LAN and the other is a standalone. I have installed an additional network card on the machine connected to the LAN. That machine is linked to the standalone through a switch using the 162.198.1.xxx sequence of IPs, with 255.255.255.0 as the subnet mask and no DNSWINS, or anything else. I can ping either machine from the other through the private network, but cannot see the files. I need to pull certain files from the standalone, but have not been able to even see them.
I want to add server(Intel PC with 2.8 P4 processor, 1GB RAM and 80GB harddisk) to my private network (not accessible from outside).I have 50 users in my network ( approximately 30 users login at same time)what simple good things that I could have on the server( website, forum,...) and what OS should I install on it?
