I have inherited a PIX 525 environment and I need to document a lot of stuff to catch-up on what is going on. I was gathering IP address information and ran "show interface outside" and "show interface inside" and noticed the same IP assigned to both. I checked the MAC address and they are different. This IP is also listed as the Management IP. So I am sort of confused. What condition would warrant both the inside interface and outside interface along with the Management IP having the same IP?
The PIX and the hosts it comms it monitors do live in a VLAN controlled by a Brocade switch which also is our gateway out.
I am able to ping from Switch to firewall inside ip and user desktop ip but unable to ping from user desktop to FW Inside ip.. config is below for both switch and FW Cisco ASA5510....

I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?
I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.
I am trying to configure our ASA 5505 so that our users can access our ftp site using [URL] while inside the firewall. Our ftp site is setup so that you can reach it by either browsing to the above url or by browsing to ftp://99.23.119.78 but we are unable to access our ftp site from either route while inside the firewall. We can access our ftp site using the internal ip address of 192.168.1.3.

I have two control point, two firewall the second one is linked inside one DMZ from the first firewall route is good and inside the DMZ from first firewall I have servers too.so to be more clear we could call as IP for the DMZ from first firewall, Interface IP 1.1.1.1 that generate this DMZ with first firewall (netmask 255.255.0.0)
inside the DMZ I have an interface from second firewall with IP 1.1.1.5 and inside DMZ 1.1/16 I have servers too keep one test server with IP 1.1.1.3.The LAN passing the second firewall is 2.2.2.1 ever 16 bits of netmask (255.255.0.0) inside the DMZ generated from second firewall I have a machine with IP 2.2.2.9 that need to access in TCP services on machine 1.1.1.3
TCP packets from 2.2.2.9 pass the second firewall and arrive inside DMZ with net 1.1/16 and arrive to server with IP 1.1.1.3 defaul gateway (to answer to originating machine with IP 2.2.2.9) is 1.1.1.1 ASA interface 1.1.1.1 claim a missing related as it haven't mapped the connection that has passed on first firewall. I need only that 1.1.1.1 route packets to second firewall (who own net 2.2/16) avoiding to be trappen in missing related check
at start it was working! around 1 year ago we upgraded IOS to 8.4 and ever so late (one year) doing maintenance to a machine I discovered it was no longer talking with these server on net 1.1/16
I have found on cisco docs chapter 51 and TCP State Bypass before was working, is something that has changed inside ASA IOS 8.4 ?
I have 2 questions.Om my cisco 2811 (IOS 12.4(15) T9 IPBASE W/O Crypto) i am using 3 interfaces.And i have a pool of Global addresses: 200.x.z.97-200.x.z.126 255.255.255.0

I have a ASA 5510 with asa8.4(2) and asdm6.4(5)205. Have a new basic config, nothing special at this time. I just cannot seem to get from the inside to the outside. From the outside interface I can ping, so I have a good Internet connection. [code]
I have ASA5550 ruuning Version 8.3(1) with inside and outside interfaces as below [code] On the inside : I have a server (10.20.10.36) that need to be accessed from an outside host (Y.Y.131.34) , so I have the below NAT/ACL rules. [code] is it right that I have to add two ACL entry for outside host to the NATed IP of the inside server , then again add another ACL entry from the same outside host to the private IP of my inside server o get this communication done?
I have deployed a read only domain controller in our DMZ as part of a domain-related project. That machine needs to be able to reach domain controllers on our internal network. To do so, it should traverse our ASA 5510, going from the DMZ Interface (security level set to 60) to the Inside Interface (security level set to 99).
I've created an ACL as following (alerting hostnames in the example):
access-list dmz_access_in extended permit ip host dmz.rodc.domain.local object-group int-domain-controllers
I've read in various spots that you have to create a NAT when traversing security levels, going from a less trusted interface (DMZ) to a more trusted one (internal.) Since this link will carry domain traffic, we do not want to create a real translation. Thus, I created a stand-in NAT that points to its own IP as follows:
Long story short, the connection fails. I'm able to access other hosts in the DMZ and on another interface configured with the same security level (which I've explicitly allowed), but trying to go from the less-trusted DMZ to the more-trusted internal fails.
A Cisco ASA running 8.2.5 with 3 interfaces: Outside (Sec lvl 0)/-nternet IP / DMZ (Sec lvl 2)-192.168.8.0/24 / Inside (Sec level 100)-192.168.1.0/24
An ACL on the DMZ which looks like this:
access list DMZ_IN permit ip 192.168.8.0 255.255.255.0 any access list DMZ_IN deny ip any any access-group DMZ_IN in interface DMZ global (outside) 1 interface nat (DMZ) 1 192.168.8.0 255.255.255.0
Nat Control is not enabled (by default) There is no nat exemption, static identity nat or any nat of any kind set up between the Inside and DMZ.The question is: Will the DMZ network be able to initiate connections to the Inside network or will only outside (internet) access be permitted?
A) No, inside access will not be permitted, only Interenet access will be permitted, because there is no NAT exemption or Static Identity NAT between the lower level security interface (DMZ) and the Higher level security interface (Inside), regardless of the DMZ ACL rule with a destination of ANY.
B) Yes, access to the Internet and the Inside can be initiated because NAT control is disabled and there is an ACL that permits DMZ traffic to 'ANY' destination.
I recently upgraded my asa from 8.2 to 9.1 (reconfigured from scratch - didnot convert old config) and everything seems to be working fine except for communication between my INTERNAL network and my DMZ. Here's my config below -
I have a 5505 that currently has inside/outside interfaces and everything is working just fine. I am trying to create a DMZ that will essentially be just for vendors/guests. the DMZ will have full access to the outside (Internet) but no access to the inside. I am using the FW for DHCP, and 8.8.8.8 and 4.2.2.2 for DNS. I currently have 1 laptop in the DMZ vlan, and it is getting a correct IP, and it is showing 8.8.8.8 and 4.2.2.2 in ipconfig. I can ping/tracert 8.8.8.8/ 4.2. 2.2/74.125.137.147(what url... resolved to on a laptop connected to the inside vlan), but I cannot ping nor browse to url.... [code]
I am very new to Cisco ASA and I am trying many days to implement the design below but still cannot get it done. The situation I am facing is
- a host (e.g. 192.168.5.10) under Inside interface can contact to outside without any problem. - however a host outside (e.g. in VLAN1 or outside this network) cannot contact host under Inside interface. I am using PING test and always get Request Time Out. [code]
I have an ASA 5520 Cisco Adaptive Security Appliance Software Version 8.4(2)8 Device Manager Version 6.4(5)206. I am trying to add a nat for outside x.x.x.77 port going inside x.x.x.22 port 80 . the wan interface is .74 with subnet of 255.255.255.248 the rule will add but traffic wont pass in.
I have an existing ASA Firewall that is configured with an inside interface and an outside interface - communications is working fine in this configuration.I am trying to add a DMZ interface that will be connected to a 3560x switch - the new ASA and Switch configuration are below. [code] I cannot ping from a computer on the LAN (10.10.10.3) to the IP address of the DMZ Switch on VLAN 510 (10.50.10.1).I can, however, ping from the DMZ Switch (10.50.10.1) to the workstation on the LAN (10.10.10.3)
I am trying to upgrade a Cisco ASA over an IPSEC VPN tunnel. My FTP server is on the remote side of the VPN tunnel but I am initiating connections from the inside interface of the firewall. I am currently managing the Firewall over the VPN via it's inside interface (using the management-access inside) command. When I try and update via FTP, the connection is going straight out the outside interface (and not across the VPN tunnel) I have tried upgrading via TFTP but it keeps stopping randomly with (unspecified error) I normally upgrade via FTP though but it's not working in this instance. Essentially what I am asking, is is there an equivalent command for FTP that there is for TFTP: tftp-server interface ip anyconnect I need the connections to originate from the inside interface so they traverse the VPN. I am running 7.2.3?
My customer has a 5510 with the inside interface connected to a routed port on a Cat3560G.When I look at the arp cache on the 5510 all inside IPs have the MAC of the 3560's routed port. [code]
NAT command on 8.4? I am trying to PAT multipule Inside subnets to an IP address. With the example I found I can only PAT one subnet. If I do it the way I have below, it will end up with the last subnet (3.3.3.0) stay in the config. What is the best way of doing it? I have about 20 inside subnets I need to PAT.
I cannot seem to determine exacly why I am not able to ping from the inside to outside using the standard 100/0 security levels respectively. I am dynamic natting the inside to the outside interface, something I don't usually do but cannot see why ICMP's are not passing through.
The Packet trace tool says there is something in the ACL but there really isn't.
Is there simply an issue of Natting to the WAN interface on a 5510?
We recently purchases the Cisco ASA 5505 to get familiar with it, possibly buying more appliances for our branch offices. However, since the appliance is installed, our SIP telephones no longer register with our SIP service provider.
The SIP phones are all on 10.0.1.0/24 while the SIP provider is external via the outside network. I copied our configuration below. how to enable SIP for all 10.0.1.0/24 hosts and ports 5060, 5160, 5260, 5360?

I have a standard ASA 5505 with inside, dmz and outside with the default security levels, 100/50/0. we have an email server inside which has been NATed and is working fine. However users accessing the wireless on the dmz are unable to access their emails on https (443). How do I allow SSL access ONLY to users on the dmz using ASA 8.4 commands or ADSM 6.4?
Most examples of NAT translation using an ASA 8.4 are based on servers within a DMZ. In my case it's not because the mailserver also functions as an data and Active Directory server for my local domain. If tried to config the ASA for a while now and throw it in the corner for a couple of months out of frustration. Now I got some time left during christmas break I decided to start again.My purpose is to NAT SMTP / POP traffic from the internet, trough the ASA to my (inside) server. This is what I got so far. With this config I'm unable to telnet the inside server (192.168.1.10) from a remote location.
I can ping 192.168.1.10 from the ASA CLI. I can Ping DNS 4.2.2.2 from the CLI (internet access). I can Telnet the server from the inside LAN, using: telnet 192.168.1.10 25.But I can't Telnet from an outside location using: Telnet 95.*.*.218 25 Because my server is on the Inside interface (diffenrent subnet) do I need an additional route?
My internet works. However port forwarding does not work. I want to port forward from the outside to inside obviously. I get an error in my log file which Ill show you and then I will share the running-config I have tried using this method found elsewhere.

I have 2 ASA and would like to build a Side-to-Side VPN between these ASA. So I can learn something about configure a ASA for different thinks. But now I don`t can Ping from a Client to the Internet-Router.My Configuration is:
I also want in internal NAT, but only for certain external hosts, so when they connect to any of the above, their source address is changed. I've attempted the following so an external host (172.16.2.254), has it's source changed to 172.16.1.100.
I'm trying to get my ASA 5505 (IOS 8.4) to work, but got stuck on NAT because I would like to allow 3389 access for just a couple of WAN IP's. This is what I found so far:
I'm trying to traverse from my inside private IP address (10.x.x.x) to my public IP address translation (172.16.x.x) in order to take advantage of the ACLs that are already applied on my outside interface. For example:
Host 10.0.0.1, translated to PAT pool Server 10.0.0.5, translated to 172.16.0.1 Inside-out access-list permits ip any any Outside-in access-list permits tcp any 172.16.0.1/32 eq 80
From my inside host, I can get go 10.0.0.5:80. I can get out to the internet. External hosts can successfully get to 172.16.0.1:80 (address scheme is theoretical). I can do everything except for connect to 172.16.0.1:80 (the translated public IP address) from my inside host address. I did not setup this firewall originally, but I can't see a blatant command that makes this not work. I don't see an ACL rule matched, so I'm assuming this is an issue with NAT or some sort of security policy. I'm running a Pix 535 /w 8.0.4. The response I got from Cisco was "create static (inside,inside) translations for every host", but that's over 300 hosts. I have a friend running the same software set and his works as expected without these static (inside, inside) NATs.
I have a ASA 5505 Sec Plus. I would like to allow outside hosts to our mail server and also our FTP server. So i would like to allow only SMTP, HTTP (for Outlook Web Access) and FTP.
I have a 5505 with Base license running ASA software v8.4(2) that has been working happily for a while with an inside and an outside VLAN.
The outside has a single statically configured public IP, and I have a number of static NAT rules to expose a few internal servers as well as Dynamic-NAT for all devices on inside to gain access to the Internet... the main bits of the config are below:
I now have a requirement to add a "dmz" VLAN for guests to have access to the Internet using a dedicated wireless AP, but not to any of the inside resources. As the ASA has a base license I have configured "no forward interface" to the inside vlan, which suits the purpose fine
interface Vlan12 description Used only for guests access to the Internet - no access to the corporate resources no forward interface Vlan1 nameif guests security-level 20 ip address 192.168.2.1 255.255.255.0
My problem is that when I try to add NATing from the dmz to the outside I get a:
ERROR: Address a.b.c.d overlaps with outside interface address. ERROR: NAT Policy is not downloaded
Having had a look at the ASA Configuration guides, all the examples I can see with several "internal" VLAN's being NAT'ed use one external IP per VLAN - is this a feature/restriction of the ASA software? Are there any workarounds? Or is the overlap in the error message really about the current NATing to the inside VLAN which is done on the "any" 0.0.0.0 subnet - would the following then work:
