I'm trying to translate my inside network of 192.168.20.0 to my outside ISP address on ASA 5505. The ping from all hosts to 4.2.2.2 works, but it still only let's one address out to translate.My configuration is:

nat (inside) 1 0.0.0.0 0.0.0.0

I guess I'll start with the easy stuff, Cisco ASA 5520 ver 8.2, ASDM ver 6.2, IPSec L2L tunnel with overlapping private IPs.
I have about a dozen L2L connections on our 5520 but never had to do one with overlapping IPs. I have two that I have to build and one definitely overlaps our inside locals, and the other is requesting that we NAT our inside locals to a 10.x.x.x.
I've searched the board and found several good posts including document 112049, but I just don't seem to be able to get my head around how to translate one inside address to another. It would seem like is would be as easy as doing an (inside,inside) static NAT, but most everything has the solution as a policy NAT or doing an (inside, outside) but in the less secure address space place the name of an ACL. I have ordered that brick of a book on ASAs from Cisco Press, but need to get something going and I'm not having much luck getting this thing up and running.
Perhaps my basic understanding of NAT rules is wrong. I thought that when using NAT the command speaks to the interfaces and the direction of travel, (inside,outside). I also thought that the IP adresses used must be valid on the interface refferenced, so any refference to "inside" would have to be an address on the "inside interface of the FW and likewise for the "outside" interface. Finally, to be sure I'm not calling a duck a goose my understanding is that the following are correct; "inside local" = my private, "inside global= my peer, "outside local"= their private, "outside global"= their peer.
So if I'm translating say a 192.x.x.x on my inside local and wanted to present them a 10.x.x.x, wouldn't I need an (inside,outside)? And even though I'm translating my private IP into a different private IP, the translated IP must be on the "outside" interface because that is the interface that I want to present the new private IP on?
So for the scenario I suggested at the top where I need to translate my private 192.x.x.x into a 10.x.x.x and present that 10.x.x.x to the other side, I need something like NAT Static (inside,outside) 10.x.x.x 192.x.x.x?
I know the CSS is too old but I have one in production environment and I was asked if it is possible to CSS to make NAT from inside addresses and translate them into one external IP address to diferent kind of communications, for example: 172.16.4.9 and 172.16.4.10 (inside addresses) should start connection to external IP addresses destinations 50.50.50.50 / 60.60.60.60 70.70.70.70 / 80.80.80.80 and so on, the default gateway to those Servers is the CSS and I would like to know if it is possible that all connection to external world to be translate into one IP address 172.16.4.100.

I 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]
We have two sites: 192.168.100.x and 192.168.101.x currently connected via IPsec VPN. On each end we have a Cisco ASA 5505. However, each site also has an MPLS VPN with intentions to move all traffic to this link. Will this work on the ASA? We need to make sure traffic can hit the ASA @ site A on the inside interface and trafiic will forward to the MPLS VPN router which then handles the traffic. Too, will it cause any problems in bi-directional flow between the two sites?
View 3 Replies View RelatedI am desperate to make some kind of translation which convert an outside IP Address of our web server to its inside ip address so that requests can be routed internally to the server.
This is what we have: A wireless network with an SSID to serve visitors. We also have an in-house web server which can be accessed internally and externally. We have a ASA 5520 that protects the internal network, including the Web server, and also routes all traffic from the all visitors connected to the public SSID to the outside. The DHCP server for the wireless network for visitors is configured to give the 8.8.8.8 as dns server. The problem with that is that the www.ourwebserver.com is resolved by Google's dns server to the public IP Address of our web server! The traffic then is sent to the outside interface of the ASA 5520. The visitor who wants to access our web server cannot connect!
How can I configure the ASA to route that traffic to our web server with the public ip address to the inside ip address of the web server?
I have an ASA5505 with 8.4 software used on a business DSL account.This means I am running PPPoE session to the provider and am then given an Inside Global subnet /29.I have various servers NATed to specific IP's then have the DHCP users NAT with overload to another of my inside global addresses. When I try to establish an IPSEC tunnel to any of my inside globals and monitor I get an access denied message but there is nothing that is blocking.If I determine my PPPoE IP address I am able to extablish a IPSEC session to that but cannot exchange traffic. Not that I want to use that IP anyway because that PPPoE Session IP changes and only my inside globals are static.I spent several hours on this and cannot put my finger on it. Do I need to allow VPN to the INSIDE interface?

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?

I have 5 workstations with 2 servers but the backup server (black) is shut down intentionally.I have 1 cisco gigabit unmanaged 8 port switch and 1 cisco 1941 vpn router.The cisco 1941 vpn router is configured for IPVPN connection to other branches.
Challenge:
1. Configure NAT to enable the 5 workstations to be connected to the internet thru the router to the ISP.
2. Configure NAT to enable the server to be accessed from outside using the public IP address provided by the ISP. [code]
Verification:
1. I can ping other pc on 10.71.5.0/24 network.
2. When I typed in the ISP's public ip address on the browser, i got into the modem user interface for configuration.
I still can't connect to the internet. When i do tracert, it stops on the 192.168.15.1 hop and didnt continue. This shouldn't be the case since i want to connect using the GE0/1 outside port for the internet.
I just purchased an ASA 5555 and started to configure. I was successful in natting all the IPs that are on the same subnet as the ASA eth0. I could not get the nat working for the 2nd address block.

ip address 192.168.1.33 255.255.255.224

I'm looking for a content filtering/antivirus/antispyware appliance for my company. Right now we have an ASA 5505 at the edge. We have several outside employees connecting via Cisco VPN clients to the ASA. I need an appliance that can do content filtering for my inside network, guest network, and VPN users. That's two local VLANs and a VPN pool which are all terminated at the ASA.
I've had good luck with Cymphonix in the past, but their boxes are a bit steep for the amount of throughput I need. We'll probably be moving from a 15/15 fiber connection to 80/10 cable soon since our provider can't seem to keep us online; even with an alleged "100%" SLA. They just don't have a network capable of anything close to 100% uptime, plain and simple.
I'd like to keep the ASA running as our firewall and VPN server, so the device needs to be able to do content filtering/av/as in a transparent mode.
I have a virtual machine running in my desktop which connected on the gigabit lan port on EA4500 with firmware 2.0.37.What I want to be able to do forward a port that came from an external ipv4 address to the ipv6 address and a different port to my virtual machine (to remote desktop port 3389).The reason I want to convert the traffic to ipv6 is because virtual machine is running vpn and is not reacheable through ipv4 (unless bunch of routes are setup and things get complicated etc). I verified my phsical server and virtual server get both ipv6 ip addresses through ipv6 tunnel from comcast. Without tunneling I could not get ipv6 setup using automatic mode with comcast, it simply did not work for some reason.

I'm not sure it's the best solution, but he insists on using his Cisco ASA 5505 Firewall via a clientless VPN. His set-up is a simple residential cable modem (Motorola SurfBoard/TimeWarner) set in DMZ mode, the Cisco ASA, and an Ubuntu server.
The Clientless VPN is set up, as are the user groups, and bookmarks. I'm able to browse to the firewall's internal interface IP (https://192.168.1.1) and log in to the Clientless VPN portal, and from there, I can access all of the plug-ins I've configured (CIFS, VNC, etc). The problem is that I cannot connect from outside the local area network.
I think it's something very basic that I'm missing, like a NAT rule. I've tried adding some, but they always seem to interfer with the NAT rule allowing users to connect, via the internet, to the Apache web server (port 80) running on the Ubuntu machine behind the ASA Firewall.
Like I said, I'm not sure this is the best solution for him. Using an ASA seems like overkill for something that can be accomplished with some software, but he and I are both fans of Cisco, and, as I said, he is adament about using this set-up.
