Cisco Firewall :: 5512X - IP Address Associated With Device Or Is It Interface Specific

Jan 21, 2013

I'm trying to get started on setting up my first Transparent ASA.I understand an ASA in Transparent Mode can now have an ip address with Bridge Groups or some such mechanism. I'm looking for examples of how to set that up and other information below. Is the ip address associated with the device or is it interface specific? Will I be able to SSH with that ip address setup? Can I use ASDM if the Transparent ASA has an ip address? This 5512X has an IPS. Any one who has setup an IPS on this platform knows it has some very particular requirments in order to communicate with the outside world. I need examples of how to do that with a Transparent ASA.How is NAT setup differently (if at all) on a Transparent ASA?Are ACLs done any differently?

Cisco Firewall :: ASA 5512x Restrict Email Delivery To Ip Address Range

Feb 2, 2013

I was wondering how to tighten the security of my email delivery to a range of ip addresses (I know how on my old firewall but the cisco is quite a bit different).  Right now anyone sending email to a particular ip address on my firewall can do so.  I want to restrict that to two ip address ranges it will accept deliver from.  I'm thinking I need two network objects for the two ranges then add to a network object group.  Configuring the ACL for delivery using that group if I'm correct about that ?

Cisco Firewall :: Force ASA 5520 Traffic Out Specific Interface

Jun 1, 2011

I'm trying to route all default traffic from my production environment through my ASA 5520 on the "outside2" interface.The 5520 has a site to site VPN to our DR site on the "outside/inside" interfaces via one ISP. On another ISP, interfaces "outside2/inside2" go to the internet.
When I make my 3750 stack default route for the inside2 interface IP I cannot get to the internet. When it is pointed to the inside interface on my 5505, I can.
I get the following errors when I try to open from a production server:Why is the 5520 trying to use the "outside" interface instead of the "outside2" interface to go out?

Cisco Firewall :: Upgrading From PIX To ASA 5512X

Mar 12, 2013

We are in the middle of upgrading from two PIX's to some new ASA5512X's. To give you some background on the situation we are upgrading these since the PIXs are fairly old. We had one extra that we had to use since one PIX has failed already. The guy that implemented the PIXs orginally was learning how to do so as he went so there is alot of needless config in the PIX, atleast from what I can tell. Another guy that works with me has done some configuration on the new ASAs and has done the majority of it so far. Today we went to install the new ASAs and switch everything over hoping it would work, but that didn't happen. It seems that there is something wrong with our NAT and ACLs somewhere along the lines. The way our network is laid out is that we have two school campus with a site-to-site VPN one is and the other is We also have a remote-access VPN on both ASA's. When we connected the new ASAs up and brought up the interfaces, nothing on the inside could ping the internet nor the other side. The VPN showed active on the ASA's and each ASA could ping the others outside interface, but that was it. I have posted the configs below.

Cisco Firewall :: 5512x - Static Translation From DMZ To Inside On ASA 8.6

Dec 20, 2012

Recently upgraded to an Asa 5512x from a pix 515e. I have an Ipswitch secure MoveIT server on the dmz1 interface that needs to be accessed from both the inside and outside interfaces. I have setup a static nat from the outside to the dmz1 and it works, I can also connect from the inside interface. Now I need the MoveIT server to access the DNS server and email server on the inside interface so it can send notifications. On the pix I just created a static from the inside to the dmz1 using its own IP address - static (inside,dmz1) net mask I would then add the access-list to allow. How would I set this up with the Asa 8.6 commands?

Cisco Firewall :: 5512X Any Extra License Or Part Number To Get IPS Features

Apr 30, 2012

url...For the New Firewalls i.e. 5512X , 5515X etc there seems to be integrated IPS and we don't need to order any extra license or part number to get the IPS features .
But for the 5585X It says 2Gbps for SSP10 engine but I have seen in the Dynamic Configuration Tool that SSP10 and IPS-SSP10 are different things . Which means that I will have to order 2 service engines SSP10 and IPS SSP10 to get the IPS features and if I only order SSP10 with that Chasis I will only get firewalling  ?

Cisco Firewall :: ASA 5510 - Two Separate Address Pools On Same Interface?

Dec 25, 2012

We have an ASA 5510 and we also have two separate address pools which have been provided by our ISP.  The addresses are not contiguous.  Is there a way to configure an interface on the ASA to handle both sets of public address pools?  If the outside interface is set up on eth0/0 would I create two subinterfaces (eth0/0.1, eth0/0.2) and assign each subinterface an address pool?  Then just NAT/PAT to my heart's content?   At that point I would want both to route to our inside network.  So it's basically two inbound sets of IP addresses comming into one interface and then comming into the network...  Right now the outside interface is configured with our first set of IP addresses.  We wanted additional addresses and when we called our ISP they told us we already had them - just a different pool.  Hence the question.  I'm guessing that I wouldn't put anything specific on the outside interface and I would put the specifics on the subinterfaces?

Cisco Firewall :: ASA 8.3(2) / PAT Interface Address With Static NAT Port Translation?

I have an 8.3(2) ASA with a single outside IP.  Dynamic PAT translates inside addresses to the outside interface address.  I would like to use static NAT with port translation to access an inside syslog server.  I got an error when I tried using the outside interface address.  Can I use both dynamic PAT and Port Translation with the same outside address?This is what I would like to use but I receive an error saying there is an overlap using the outside interface address.( is my inside network. is the outside interface IP.)

Cisco Firewall :: ASA5510 - Change Public IP Address On Outside Interface?

Mar 10, 2011

we have two Cisco ASA 5510 in failover configuration.We tried to change the public IP address on the Outside interface of the primary device but it didn't works. The new IP is not reachable from Internet nor pingable from device on the same LAN.The new IP address is in the same subnet of the old IP.

From the switch on which the ASA is connected and from another Cisco PIX we can see the ARP entry. In the analysis, on the old public IP address there was a VPN site-to-site and Webvpn defined.We tried also to shut/no shut the interface and reboot the device.

Cisco Firewall :: 5510 - Duplicate IP Address With ASA Inside Interface

Apr 5, 2012

We've had issues with our Exchange 2010 server (running on ESXi 4.1) since its default gateway was changed to our new ASA 5510.  They manifested as frequent Outlook client connection dropouts or as IP address conflicts whenever Exchange was rebooted.  The temporary fix was to disable the Exchange server NIC, bounce the ASA and enable the server's NIC again.  We saw poor performance from Exchange after a while again, but after some research and testing I realised that disabling proxyarp on the inside interface fixed the problem permanently.
However I've now realised that the client VPN no longer routes properly because proxyarp is disabled on the inside interface, so I still have a problem.

What is happening now, users get authenticated as long as they exists in the AD, luckily they fail on authorization, as it is bound to specific AD group.
how can I bind the authentication aginst specific group in AD, not just using AD1 as the identity source.

I have two ethernet adaptors on my windows machine. OS is Win-XP.I am running ADSL broadband on LAN1 and on LAN2 I am accessing applications on our company's WAN. LAN1 is on subnet and LAN2 is on subnet.Accessing application through LAN2 involves DNS that is located distantly, therefore routers are also in picture.Problem is that while accessing the application that run on the network of LAN2, I have to disable LAN1. Otherwise the traffic goes on LAN1.

Linksys Wireless Router :: E3000 Possible To Limit Access For Specific Device (PC) To LAN Only

Dec 31, 2012

Within the Internet Access Policy section of the browser based utility, is it possible to limit access for a specific device (PC) to LAN only (not allow any traffic to external internet)?  I see that you can block internet access for a specific machine, however I didn't know if this was inclusive of LAN as well.If not, is there another way to achieve this via the E3000 or should I be looking for a solution on the specific PC itself?

Cisco WAN :: 1841 To Block Access To A Specific Interface

Feb 11, 2013

I have an 1841 between my firewall and the ISP.  Three interfaces - multilink to ISP, FA to my firewall, and FA to my inside network.  I use the inside interface for configs aand snmp access, etc.   Only my ISP-assigned fixed address block will get routed to the multilink by the ISP but I am nervous about the inside interface sitting on my LAN.   I know I can remove it, but if I keep it there, how can I set up an ACL so that all traffic from the multilink interface is denied to the inside interface?  I suppose another way to think about it that the inbound iface can only accept traffic from its own outside, not from the router.I think this is fairly simple but I don't want to knock down the traffic if I get it wrong.

Cisco VPN :: ASA 5510 - Configure Remote Access VPNs To Use Specific Interface

Aug 12, 2012

I am adding a second external connection to an existing system on an ASA 5510 with ASA V8.2 and ASDM 6.4. I added the new WAN using an other interface (newwan).
The intention is to route most internet traffic over the new route/interface (newwan) but keep our existing VPNs using the former interface (outside).

I used the ASDM GUI to make the changes and most of it The default route goes via (newwan). Outgoing VPNs of a site to site nature use the previous route via (outside) as they now have static routes to achieve this.
The only problem is that incomming Remote Access Anyconnect VPNs are not working. I set the default static route to use the new interface (newwan) and the default tunneled route to be via (outside) but this is the point is goes wrong....
I can no longer ping the outside IP address from an external location. It seems the outside interface does not send traffic back to the - outside interface (or at least that's where I think the problem lies). How do I force replies to the incomming VPN remote traffic from unknown IPs to go back out on the outside interface?
The only change I need to make to get everything working on the outside interface again is to make the Default Static route use the outside interface. Which puts all the internet traffic back on the original (outside) connection.
