Cisco Firewall :: NAT In ASA 5505 Version 8.3
Mar 14, 2011
I need to fullfill the below configuration which is working fine on my actual D-Link Netdefend firewall.
We have a range of IP assign by our ISP : 194.250.47.128/29
194.250.47.129 is the firewall IP and 134 the isp gateway.
We have 4 interfaces
- The local user interface: lan =192.168.170.1/24
- The servers interface : dmz =192.168.171.1/24
- The database interface : oracle=192.168.169.1/24

ASA 5505 Version 8.2 or older nat (inside) 1 10.0.0.0 255.255.255.0nat (INTF4) 1 10.0.4.0 255.255.255.0nat (INTF5) 1 10.0.5.0 255.255.255.0nat (INTF6) 1 10.0.6.0 255.255.255.0nat (INTF7) 1 10.0.7.0 255.255.255.0global (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224global (outside) 1 interface
I believe this setup does the following. The inside interface and interfaces 4,5,6,and 7 will translate using this line....
global (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224
and if the addresses run out is will start using the ouside interface IP address to translate, so traffic is not disrupted and is based on the line of configuration.....
global (outside) 1 interface
My question, does it do this because of the order of the configuration..
global (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224global (outside) 1 interface
or would it do it that way even if it was like this?
global (outside) 1 interfaceglobal (outside) 1 209.165.200.235-209.165.200.254 netmask 255.255.255.224
and if so why?Now let's convert the above configuration to ASA 5505 Version 8.3 or newer.
object network OUTSIDE-NAT-POOLrange 209.165.200.235 209.165.200.254object network INTERNAL-SEGMENTSsubnet 10.0.0.0 255.255.248.0nat (any,outside) dynamic OUTSIDE-NAT-POOL interface
My question is how does it know to use the outside interface as a backup when the OUTSIDE-NAT-POOL is depleted?Also why do I need to define the INTERNAL-SEGMENTS ? Doesn't the "any" in the (any,outside) take care of that?Also wouldn't the "any" in (any,outside) cover interface 3 or DMZ which could be an issue?

I've have an ASA 5505 with a inside network vlan1 (192.168.0.0/24) - i've configured an IPsec VPN profile and a VPN network of 192.168.0.50/24. I can through my VPN tunnel access inside hosts on vlan1 - but not ASDM on the ASA (192.168.0.1). Under management i've added the VPN network of 192.168.50.0/24 to have access to ASDM, but still does not work.

I'm trying to configure UC-Proxy using an ASA 5505 with software version 8.0.4.I was following the instructions in DOC-5704 and ASA 8.0 CLI.I don't have USB security tokens in UC solution, instead I'm using IP phones Cisco 7961 with MIC.I configure all the items as the documentation says but when I restart the phone outside the Firewall, the 7961 don't registrate with the Call Manager.Checking the troubleshooting I found that it's possible certificates problems but I don't know if I need to do something in phones.
I would like to know if there is any consideration when the UC proxy works just with MIC.The outside phone is a Cisco 7961 configured with static IP address and TFTP address of Call Manager (static NAT in ASA).

I just upgraded my firewall to ASA 5505. Now, my original static ip address cofiguration is gone. Apperantly, Cisco went away from static ip address to something like nat (inside,outside) dynamic interface. how to create a static ip address under version 8.4? By the way, I am sharing what my configuration used to look before upgrading.
!
hostname cisco-asa
domain-name default.domain.invalid

I have upgraded an ASA 5505 to 9.0(1) as I would like to use ipv6 version of dhcprelay. That said, I am unable to obtain a global unicast address but the link-local address is able to communication with the ISP's gateway/DHCP provider which I hope will allow v6 dhcprelay provide internal clients with IP's from the ISP. Trouble is, unsolicated inbound ICMPv6 messages from the ISP's gateway are being dropped on the way into outside interface.
%ASA-3-313008: Denied IPv6-ICMP type=129, code=0 from fe80::201:5cff:fe3b:3c41 on interface outside

I have been using ASDM on a "Cisco Adaptive Security Appliance Software Version 8.2(5)" for a long time and in order to route packets among the interfaces without NATting the packets, I have always been using the function "Add NAT Exempt Rule" under "Configuration -> Firewall -> NAT Rules". Everything has always been working fine.
Now I am trying to use ASDM on a "Cisco Adaptive Security Appliance Software Version 9.1(1)" and I cannot find how to do the same operation: the "Add NAT Exempt Rule" option is no longer available and the only way to make the traffic passing through seems to be NATting it on the OUTSIDE interface.
where I am mistaking? My goal is to let the traffic passing through from the inside interface to the outside interface without being translated.

On the downloads page there's a 9.0.2.ED listed as the 'latest' but then if I expand the '9' below it I get to 9.1.1.ED. Which one is the actual latest? is there any way to tell the one that is not an 'interim' version I think 9.1.1 is also listed under interim?

I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?

I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?

I try to convert a CISCO ASA 8.2 version to 8.4 BUT, I have a small or "little" problem :On Cisco ASA 8.2.x, i have a possibility to create multi-line global with different subnet.Example :
global (outside) 2 217.1.x.65-217.x.x.66 netmask 255.255.255.240
global (outside) 1 interface <-- Ip interface is other subnet : 217.3.x.3
global (outside) 2 217.1.x.67 netmask 255.255.255.240
nat (inside) 1 0.0.0.0 0.0.0.0
nat (dmz2) 2 192.168.4.0 255.255.255.0
What is the method or solution to translate multi-global in 8.4 ? with static translation in 8.4 : i try to use different server in inside's zone, but not in same network on outside. In 8.2 Firmware, it's very easy to use that, but in 8.3-8.4 version, i don't have some idea to manipulate ...

We have 2 firewalls on PIX facing the Internet and connected to interface e1 (behind it) an ASA version 8.3 Both the PIX (Firewall facing) and the ASA are on the same subnet.
By using Routing statements and statics I have been able to reroute specific traffic to the ASA5520 version 8.3 Now I need to inverse the 2 devices. The ASA5520 will be facing the Internet and the PIX will be behind it.Unfortunately the ASA5520 is refusing to route the traffic to the PIX. The access-lists are open accordingly and a NAT on the ASA has been created.
