Cisco :: ASA 5505 DMZ Do Not Talk To Inside Network
Jul 29, 2011
I have a 5505 with the security plus license. I have a web server in the DMZ that needs to talk with a server on the inside network but it doesn't seem to be able to. Im guessing there is something I need to do to enable the DMZ to talk to the inside network.
I have setup two different subnet 192.168.1.0 and 192.168.2.0 on the same 'inside' interface. They are unable talking to each other. I can ping from firewall to both subnet. Both side unable talking to each other unless I add route on the both side systems.I have added the followings in ASA5510. [code]
I've got an aol engineer visiting Thurs.to examine connection loss (since last Weds). But I'm convinced the problem is with the router. But from the tone of the aol tech questions I suspect he's already briefed his engineer to do his best to represent the problem as being either with my computer or positioning of router/filters/condition of wall-sockets - usual getouts.The talktalk router is neww, issued Feb 12, after my original router, speedtouch, started suffering idle timeouts every day.
I can connect to this router via Lan and have no problems.Via Wi Fi it connects but will not communicate with the router or see find the router vias ip address..I have turned on auto ip finding in network settings for Lan and for Wireless but wi fi still does not allow access to internet. It just says local only.when i go to Command prompt and do ipconfig /all it says all DHCP enabled are off!!
Got a problem accessing our webservers on the inside interface from other clients on the inside interface on our ASA 5505.As in, they type in url... in their browser, and it wont work.
However, if we use a PC on another outside network, it works just fine! [code]
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.
What do I need to do for access inside network to DMZ?
I successfully configure, internet Access for DZM and inside network, web server can be accessed from internet, but I have problem to configure communication from inside network to DMZ.
I'm trying to get a couple clients to talk to my Active Directory servers. I've created sub-interfaces on my ASA. So, my clients are on Gi0/1.139 and my two Active Directory servers are on Gi0/1.132. I've enabled traffic on TCP 53-5000 port range according to Microsoft. My clients still can't join the domain. What ports I need to open up? My AD servers are Windows 2003.
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:
global (outside) 1 interface nat (inside) 1 0.0.0.0 0.0.0.0

i am having trouble connecting my msi laptop to my talktalk to router i have another laptop that i cant really use however i turned it on to c if i can connect it to internet and i can but can not not matter what i do connect this one.
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'm setting up a VPN in order to share files between two locations. 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. If it comes down to it, I'd like to be able to honestly tell him that I exhausted every resource in trying to find a way to make this work for him before giving up and going to "Plan B".
I've setup a SSL VPN to a ASA 5505 and can connect.
VPN network 192.168.2.0 /24 Inside Network 192.168.1.0 /24 Outside is connected to Router.
I am trying to RDP to a win server on the inside network but I cant get to it. Can not even ping 192.168.1.1 or (not sure if I could anyways) 192.168.2.1...
I added a ACL on the outside interface and then inside interface permit ip any any but still no ping or RDP...
New at VPN and have survived so far on cisco docs but this problem is evading me.
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]
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?
I'm having problems getting AnyConnect clients to reach a server (192.168.139.3) on the Inside interface of my ASA 5505. Ideally, this would be accessible from the DfltAccessPolicy or another dedicated policy, but right now I'm happy with any access. Everything else seems to be working as expected. I've rebuilt this config a number of times without success. I can ping the IP from the ASA itself.
I've setup a SSL VPN to a ASA 5505 and can connect.

I am trying to RDP to a win server on the inside network but I cant get to it. Can not even ping 192.168.1.1 or (not sure if I could anyways) 192.168.2.1...I can ping from the 192.168.1.0 net to 10.0.0.0 and 192.168.2.0 without issue but not the other way around....I added a ACL on the outside interface and then inside interface permit ip any any but still no ping or RDP...
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 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:
I have an ASA 5505 with the typical inside/outside interfaces. I also have a DMZ that I've named remote for all of my ISP VLAN'd remote offices to connect. I've set the security levels on both the inside and remote interfaces to 100. From remote 192.168.71.0 network I can ping to the remote interface on my ASA, 12.230.129.66/8, but can't ping anything on the inside network, 192.168.1.0, or the web. From my ASA I can ping the router directly attached to the remote interface, 12.233.136.162/8. From my inside 192.168.1.0 network I can hit the web fine, but cant ping the remote router 12.233.136.162 or the remote network..
I dont' know if I missing something with routing, or with the two interfaces w/ same security...or what?
Here's my config. I've also attached an awesomely bad network map.

I have a new ASA 5505 and all is working fine, I can CLI and ASDM into it, but just can't ping the inside interface, do I need to enable a feature to make this work somehow?
I am connecting the inside interface to an upstream switch and therefore will need to assign a static IP address to the inside address as I did below:
#sho int ip brief Vlan1 123.123.123.123 YES manual up up
I will also use this to manage the ASA. I am having a problem with the network configuration of the inside interface as I can't ping the gateway and/or the in IP of the inside interface.Do I need to add any routes?
I am unable to Telnet/SSH/RDP from my inside network to my DMZ. I am not sure where the problem lies, I am able to use VNC from the inside to the DMZ (ports 5800, 5900), and also establish connection on Ports (26700-26899). I have a computer connected directly to the DMZ and those services work to all networks on the DMZ.I have attached Logs of successful VNC connections, unsuccessful RDP and Telnet sessions, and the running config.
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?
For some reason there are some sites that I cannot access websites from inside interface.One such example is lxer.com where I am receiving this message in the browser:The connection has timed out The server at www.lxer.com is taking too long to respond.This has "suddenly" happened, and so I am wondering what others have done when such things has happened. My outside has a dhcp-IP, and I have noticed that this address had changed, so I corrected this in my router settings.ASA version is 5505
I trying to allow traffic between 2 inside interfaces with the same security level. VLAN1 and VLAN15. The are on different physical ports on the ASA. I tried to configure this through the GUI Web interface and checked ' enable traffic between two or more interfaces with the same security levels'. With this ASA version, I do not need NAT to allow this, correct?
We have an ASA5505 UL bundel, updated with this license "L-ASA5505-SEC-PL=" to enable traffic from DMZ to Inside. No NAT or rules deployed for that yet.
On the Inside we have Exchange 2007 in a single server installation. The public url for smtp, ActiveSync, OWA and Outlook Anywhere is mail.company.se. There is a static NAT for outside traffic to access above mentioned services on inside. Now, on DMZ there is the WLAN for guests to access the Internet. How ever, our Smart Phones with WLAN turned on, cannot sync to the Exchange Server on the Inside! The DMZ gets IP-addressen from ASA on DMZ Interface with external DNS configured. How can I configure the ASA to achieve the function of ActiveSync from DMZ to Inside with the public URL from the phones?
I have a cisco asa 5505 and i need a public ip address on the inside of my network without NAT. for example: I can create a static nat translation rule, but this is not what i need.
