Cisco Firewall :: HTTPs Access From DMZ To Inside On ASA 5505
Jan 5, 2012
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?
Configuring an asa 5505 with 8.42 software.I need to access an https server on the inside via the outside interface. have moved the http server enable to port 10443.Tried to make a "network object nat rule"
I have a closed network that is not connnected to the internet, just other sites that we want to communicate with. We have a cisco router connected to the outside interface on an ASA5505 and a cisco router connected to the inside interface on the same ASA5505. I have an inside interface that connects our management LAN, five separate DMZ interfaces with a separate LAN (VLAN) on each DMZ interface and the outside interface that connects to the other sites. Data is not allowed to mingle between the five DMZ's.
Alll connections to the other separate nodes are handled with the router on the external interface. IPSEC GRE tunnels have been established between all sites and BGP routing has been verified. Pings are good between inside, dmz and external interfaces and between the DMZ's and the other sites, to include hosts on our local networks and hosts at the remote sites. Inter and intra traffic is enabled.
When a remote site attempts an https connection, the initial ACK handshake makes it through the ASA5505, but the return SYN/ACK is being knocked down and I don't understand why (it is not because of ACL's, they are any any at this point).
Why the return SYN/ACK to the remote site isn't getting through the ASA5505 outbound. Will probably have the same issue with FTP, but right now, just trying to solve one problem at a time.
ASA5505 is in routed mode, not looking to NAT since the IP addresses in the DMZ need to be reached by their real IP address.
I have been asked to set up remote access VPN on an ASA 5505 that I previously had no invlovement with. I have set it up the VPN using the wizard, they way I normally do, but the clients have no access to anything in the inside subnet, not even the inside interface IP address of the ASA. Thay can ping each other. The remote access policy below that I am working on is labeled VPNPHONE, address pool 172.16.20.1-10. I do not need split tunneling to be enabled. The active WAN interface is the one labeled outside_cable. [code]
I'm having trouble setting up the correct rules on an ASA 5505 I'm using in my home office. I have a couple of IP Cams I need to access remotely.
I've tried setting up simple NAT(PAT) and/or Access Rules, but it hasn't worked. I have a single dynamic IP for the Outside interface. Call it 77.76.88.10 and I am using PAT. The CAM is setup to connect on port 80, but could be configured if necessary. I've tried setting up NAT Rules using ASDM as follows:
Match Criteria: Original Packet Source Intf = outside Dest Intf = inside
[Code]....
I'm afraid to use CLI only because I am not confident I'll know how to remove changes if I make a mistake.
I have a cisco asa 5505 firewall. Is it possible to block secure websites in it like [URL]? I have already tried regular expression filtering but it filters only http traffic.
I'm trying to access my ASA 5505 by https://192.168.1.1 but I can't. I'm using Windows 7. I already have installed ASDM and I can enter in the box by ASDM. I am preparing to reformat my PC and I'm afraid that I won't be able to access my ASA if I do.
The Mozilla show the message: An error occurred during a connection to 192.168.1.1.Cannot communicate securely with peer: no common encryption algorithm(s).(Error code: ssl_error_no_cypher_overlap)
I have an ancient Alteon load balancer which only supports HTTP and telnet access. Our management people only allow HTTPS through the management firewall farm, and don't want to change this policy. So I need a low cost HTTPS to HTTP conversion, ideally on Cisco hardware like an ASA5505. It only needs one concurrent user. Is there a way to configure an ASA 5505 to terminate the inbound HTTPS seession and re-originate a HTTP management session to the Alteon? It looks to me as if the Clientless SSL VPN might do the job.Is there a way to do a SSH to telnet conversion on the ASA, or on a router?
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 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.
Here is our current confguration:

I have an ASA 5505 with the base license,When I setup the DMZ interface I had to add the deny access to the inside VLAN. The DMZ works fine with WiFi on it, but user's iPhones can't get email unless they turn WiFi off.Is there a simple way to allow HTTPS traffic through the DMZ interface to our internal Exchange server which is NAT'd on the 5505's external IP?
I have an ASA 5505 that I am using to connect my contractors to via an inside interface, the outside interface is my private LAN. I have setup on our corporate Proxy server to allow traffic from my outside interface of my ASA to go to the internet without credentials BUT log internet activity. The question is I want to know if the ASA can send that http & https traffic to my proxy server and all other traffic to my default route? I want to be able to send all internet traffic to my proxy server. This will avoid me asking the contractors to place proxy credentials in their browsers.
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 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 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.
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?
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.
I have an ASA 5505 that I'm trying to set up a guest network on. I've configured an interface as a trunk and allowed the 2 vlans but I'm not getting any layer 3 to it. The switch connected to it is a 3560 and port is configured as a trunk with the same vlans.
I can't ping the ASA inside interface but I see its MAC address in the swtich's table.
Inside is connected to my internal network, inside 2 is connected to the network of a sister organization, outside is outside.
I'd like to be able to route between from inside to inside 2, and have NAT translate me to inside2's address.
I have inter-interface traffic configured, and when I use a NAT exemption, I can route fine. But the resources on network 2 must see my request as coming from the inside2 interface IP.
i have an asa 5505 firewall with asa version 8.2(1). my asa connected on wan port over isp router on internet.inside users connected over dlink switch and the allied telesis 24 ports switch on this asa. the inside users are blocked and they can't communicate. all inside ports of asa 5505 are in one vlan and all ports are switch ports. the configuration of my firewall is
