Cisco Firewall :: ASA5510 - Connect Two 10.10.10.x Networks Using NAT
Dec 26, 2012
I've got an ASA5510 with an IPS/IDS module. Because of a merger, I've got two 10.10.10.x networks (West and Central). I'd like all West traffic to be IPS checked before going into Central. Once it goes into Central, it's out of my hands. Can I set up NAT to accomplish this?
Again, the traffic flow would be from West (10.10.10.1) through the ASA/IPS, and then to Central (10.10.10.1).
Is this possible? If not, do I need another router?

We recently got a Cisco ASA 5510 Security Appliance and I have some general question.
We have 1 T1 internet connection, and we have 2 internal networks. These 2 internal networks currently hav access to the internet. I am having issues with the 2 internal networks being able to communicate with each other.

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 have an @Remote appliance through Ricoh for our copiers. This appliance connects to their site to transfer meter readings and other information. This appliance can't connect to their site to transmit data. Ricoh is telling me the problem is on our firewill. I have assigned the Ricoh appliance a static IP address in our network. Our firewall is a Cisco ASA 5510. I don't have much expereince with logging on the ASA, so I'm not sure what "teardown dynamic TCP translation from inside" means. Is there something that is preventing this IP from contacting the Ricoh site? [code]

We have an ASA5510 with the IPS ASA-SSM-10 module installed. All is working well except event notification. When sending a test email from the SSM IPS, we get the error "could not connect to SMTP host". The Exchange SMTP host does allow traffic from the IPS and ASA. I can ping to the SMTP host by IP and name. What am I missing here?

I'm configuring an asa device for web access: SSL VPN service. I can have a user authenticate for web session with their active directory domain credentials (username and password). Once their web session has started, moving to the "browse networks" feature for a share viewing requires them to authenticate once again - "authenitcation required". I'd like to configure the device so that authenticating to the windows file share will be attempted using the previously entered credentials.

I've cloned the configuration off one of my ASA5510's to another 5510 to use as a template for a new data center deploy. I have configured the new firewalls networks and rules, and of course changed the WAN IP config to its new setting.
I want to test the firewall in y office before I deploy it. How should I configure my Macbooks ethernet configuraiton to test the firewall?, as I have tried without success to connect to it.
Let's say that my WAN configuration is 134.5.169.98/255.255.255.224 with a static route of IP address 0.0.0.0, Netmask 0.0.0.0 and a gateway IP of 134.5.169.97.
I've tried setting the route to force all traffic through the interface (sudo route add 0.0.0.0/1 134.5.169.98), but that did not work either. A trace route to the external interface IP of the firewall (or the external IP of an expose server) get's a "no route to host" error.
I've tried many configurations and have not been able to access the internal servers/services/VPN at all.I've also tried with a cross over, and straight through cables.
What should I configure my macbooks network configuration as so I can connect directly to the WAN port to test external access to the internal servers/services and test the VPN client?

I have two ASA5510's set up in failover, and the secondary keeps crashing after doing the interface checks when bringing failover up. This only happens if I try to upgrade the image on the secondary to anything newer than 8.4.1 (I've tried with 8.4.1-11 and 8.4.2). The primary one run just fine with new images.
I don't have the exact error right now, as I need to do a screen capture from console. It's just a huge crash dump.Are there anything I might have missed during the upgrade? Should I cold-boot both the firewalls in the correct order?

I have a ASA5510 and I have a question about the speed the ports can handle, here is one port:
-interface Ethernet0/2
- speed 100
-shutdown
- no nameif
-no security-level
-no ip address
it's ethernet and not fastethernet so I figure it will only go to 10Mbps, but at the same time I can hard code the speed to 100.

I was planning to do in active /standby mode for failover .But i have a doubt , when i do "show version " on live asa output says Active /active failover , does this means that i can only configure failover in active/active mode not in active/standby (which i want to do )?

We have to use scp on all of our network devices. It worked quite well on our routers and switches but I can't seem to get it to work for the firewalls and IPS. I enabled scp on my ASA5510 using the command "ssh scopy enable". I also ensured that a rsa key was generated and that ssh ver 2 was enabled. But I can't seem to locate the commands to actually have my firewall either copy it's configuration to a server or reach out to a server to pull down a file. We are using IOS 8.2(1).

My device has 3 interfaces configured: inside, outside, DMZ. Right now I can access the DMZ from the Internet and I can access the DMZ from the LAN using an exempt nat statement. I am having a few issues setting up DMZ > LAN access however. The servers running on the DMZ need to send information to my LAN such as syslog traffic for example. Will DMZ traffic be NATed or should this somehow be excluded? Bascially all LAN devices should get to the DMZ devices by their actual IP and vice versa. Are there any special statements I need to add to the ASA such as nat or ACLs to make this work? My LAN is 10.10.6.0/24 and DMZ is 192.168.254.0/24.

I am having ASA5510 firewall which has 1GB RAM currently. I want to upgrade to 2GB. When I opened the box, I can see only 1 slot to insert the RAM. I searched in Cisco website and I got to know that I need to use 2 x 1 GB RAM. So, I need to have 2 slots to do that. But, I am having only 1 slot in the box.

We have an ASA5510 with a backup ISP connection protecting our corporate network. I also have a mail server and I would like to route SMTP traffic over the backup network. I realize that the ASA5510 does not support PBR, but I also know that I can use static NAT rules as a workaround to direct specific types of traffic over a particular interface (e.g. "static (outside,inside) tcp 0.0.0.0 www 0.0.0.0 www netmask 0.0.0.0" and "static (backup,inside) tcp 0.0.0.0 smtp 0.0.0.0 smtp netmask 0.0.0.0"). is it possible to use something similar to force a particular host to use a specific interface? I have tried to make this work on my own without success. Is it even possible?

We are about to upgrade our ASA's from 7.04 to 8.2. Obviously I will be opening a TAC case to assist with the upgrade and I will also be upgrading ASDM software at the same time. These production firewalls are paired with an active --> failover scenario and not active --> active. I had previously engaged cisco regarding the upgrade and they have recommended an upgrade path to ensure success. Also, I have a pair of test ASA's that I've gone through the upgrade process with - documenting the changes in commands and any changes in my config (I didn't notice any).So, the reason for my post is this: What are the gotcha's that you may have run into when upgrading your ASA's?These are fairly high visibility ASA's and any downtime due to the upgrade needs to be mitaged as much as possible.

I have a 2811 ISR configured to provide the following services to my network:
Internet access to LAN users Cisco Call Manager ExpressSite-to-stie VPN to 3rd party networksVPN server to provide VPN access to remote usersSecurity Zone configurationsStatic NAT configurations Now I recently just got the ASA5510 device and I am not sure how to go about with the setup, whether to put the ASA in between the internet and the ISR (Internet - ASA - ISR - LAN), or put the ISR in between the internet and the ASA (Internet - ISR - ASA - LAN)?
While i know I can move most of the config unto the ASA, i know that the CME cannot be moved, hence I would like to do the setup such that users on the network still have access to CME.

We have an ASA5510 and I am getting absolutely no response from the console port. Not even a blip when I turn it on. If I leave the compact flash in the internal bay, I get Green Power, Amber Status, Amber Active and Green VPN when I start it up. The Flash LED flashes Green twice then goes out. If I move the compact flash to the external bay, all of the other lights remain the same as described above but the Flash LED goes to steady Green. How ever, there is still no response whatsoever from the console port. Have replaced the DIMM but that had no effect. This is a four (4) slot ASA5510 and I have just the one DIMM in slot P13 as described on a post I found. The power supply fan comes on as well as the two (2) fans that cool the heatsink. The other two (2) fans on the expansion module side do not come on.

We just switched to a 5510 from a PIX 515 last evening, and the only things that are not working are any services from the outside to the inside. Example: I am unable to connect to a RDP server on the inside from the outside. I've been looking at the config for the past five hours, but am unable to see my mistake. Running 8.2(1) People on the inside are able to get out.

Upgrade from firmware 8.21 5o 8.31? I am installing 1GB of memory in my ASA 5510 and in the process I have upgrade the firmware.
- Will the upgrade change my configuration or will I have to change this manually myself at some point
- What is the meaning of "Real IP" I am not sure what the means (reading up on it now)
- What else should I be concerned about during the upgrade?

i need to move from a pix 515e. V 6.3 to a asa v 8. From what ive read i can use the pix to asa tool to get the converted configuration file to the new asa. So far so good, however, the pix has conduits which i read must be converted via the occ tool. So i ran the pix to asa conversion then ran the occ tool on that output but i keep getting errors. It is not liking the nameif outside, inside, and dmz lines. If i manually edited them out before i run the occ tool it runs but warns there are no interfaces.

We have an ASA5510 which keeps resetting itself for no apparent reason. It does this several times a day and I cannot see any pattern to the times etc. I don't believe it is load related as it also happens overnight when very little is going through the device. When it happens the device just drops off the network (all interfaces) and then when it comes back a few minutes later we can see from the system uptime that it has in fact rebooted itself.
I initially thought it was faulty hardware, so I swapped the device for another 5510, but that does the same thing. I then added a third 5510 and configured it in with the second one as an Active/Passive failover pair. Both devices do the same as the first, the only differences now is that the passive device kicks in and takes over, so we have a little less service disruption each time.

We have network topology:
Inside Network (172.168.1.0/27) --- ASA5510----- Outside network (192.168.10.0/24)
ASA5510 have: Inside interface: 172.168.1.30/27; outside interface: 192.168.10.254
And we config:
# object network obj_inside
# subnet 172.168.1.0 255.255.255.224
# nat (inside,outside) dynamic interface
[code]...
So, we í in from outside, we can't access web at 192.168.10.10?
