Cisco Firewall :: ASA 8.2.5 - DMZ To Inside Access?
Oct 18, 2012A 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.

Sep 13, 2011I'm having problems getting AnyConnect clients to reach a server (192.168.139.3) on the Inside interface of my ASA 5505.

Cisco VPN :: Access AnyConnect VPN From Inside ASA 5540
May 5, 2011I have a ASA 5540+SSM-40 on which I have configured webvpn and it's listening for connections on the outside interface. It can be accessed from outside the network (the internet) and works just fine. The problem is, I want to access it from inside the network as well but it doesn't work. I can't ping or connect in any way to the IP address of the outside interface from inside (so I suppose it's not strictly related to the configuration of the webvpn).
I don't think it's a ACL issue because the only ACL filtering I do is on the OUTSIDE-IN (facing the internet), the rest are set to permit any.
What I have to do to be able to access the IP address of the outside interface from networks behind the inside interface?
Cisco :: Allow Inside Hosts To Access A Specific Network?

I created an 'object' for the device and added a Static NAT entry for it, then added an access rule. Its not working so I am guessing I did it wrong. The device uses port 8000 which I also added to the object. correct commands, or using the ASDM works too.

Cisco WAN :: 2821 Cannot Access Inside Server By Its Public IP
Jul 5, 2011The router is 2821 and is setup to perform static NAT from one internal ip address mapping to one external ip address for each of our servers (inside the LAN): [code] Servers all have internal ip addresses and each of them represented to the outside world by their public ip address with above command on the router. Here is the problem.When I'm in a server (for example 192.168.0.210) and try to access other servers by their public ip addresses (i..e. *.*.*.211) the connection fails. However, When i try to access the same server by it's private IP address (i.e. 192.168.0.211) it works!
My issue is i don't want to modify windows host file for a manual mapping (for example mail.mydomian.com goes to 192.168.0.211 rather than *.*.*.211) because we host many domains and just doesn't make sense to do it one by one.So we must be able to access our servers by their public IP addresses in order for us our applications works correctly.

Cisco Firewall :: ASA 8.4(3) - Access To Public IP Address From Inside
May 22, 2012I need to connect from an inside host to a host located in the DMZ zone for DNS queries. The host in the DMZ zone has a static NAT to the outside. The point now is that I would like to connect from inside to the NATed outside address, means to the public Internet address.
Inside host: 10.0.0.1 -> PAT for 10.0.0.0/8 to 20.0.0.254 (Outside Interface)
DMZ host: 192.168.1.1 -> NAT to outside to 20.0.0.1
The traffic should be 10.0.0.1 udp>1024 to 20.0.0.1 udp=53. The source IP address on the outside interface now is 20.0.0.254 (according to the PAT), the destination IP address 20.0.0.1. The DNS reply from 20.0.0.1 should go back now to 20.0.0.254 and then to the inside host 10.0.0.1.
I know that on the PIX it was not possible, to have outgoing traffic on the outside interface which immediately enters again the same interface. Can I realize this scenario with the ASA 8.4(3) release now?
Cisco Firewall :: Inside Access Using FQDN To Web Server On DMZ 571
Aug 21, 2011What I have is 3 interfaces on my PIX.- Outside: 216.116.87.0/24 (security level 0)
- 469: 172.16.6.0 /24 (security level 10)
- 571: 192.168.255.0 /24 (security level 1)
My users on 571 need to access a web server on the 469 interface. However, the requirements are that the 571 users can only access the Website using the public FQDN which there is a static NAT from outside to 469. [code] Here is also the Packet-Tracer and it shows what I expect that the traffic is source from 571 and exits 469. However, the users are not able to access the website.[code]
Cisco Firewall :: HTTPs Access From DMZ To Inside On ASA 5505
Jan 5, 2012We 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?

View 6 Replies View RelatedCisco Firewall :: Slow Access Or NAT To Inside Interface On ASA 9.1
May 13, 2013I did this on the PIX and it worked like a charm, but I am having some difficulty translating the configuration to an ASA.
In the PIX I performed NAT on outside traffic to a specific inside host (web server) to map to the inside interface so that return traffic would go to the same firewall the traffic came in through, The reason for this configuration was because the gateway of last resort was a different firewall and not the firewall the traffic came in through.
Now to further give you some history, the gateway of last resort is an ASA running 9.1 (Now), prior to that it was a PIX with v8.0(4), traffic to the aforementioned web server came in through the gateway of last resort), which at the time was the PIX.
However, for some reason after swapping the PIX for an ASA (same rules, updated NAT rules for 9.1) access to the same web server is slow. Not sure why, but it’s the case. To alleviate the slowness we experienced, and until I can figure out why this occurs on the ASA, I placed a PIX on the network that only listens for traffic for the web server in question. On this PIX I map to the inside interface so that traffic flow works and external clients can access the web server with no issues.
So two questions, one I would like to use the configuration I have for the web server on the PIX on the ASA to see if that setup on the ASA works better, but having difficulty translating the rules to the ASA.
Second question, (Slow access with ASA to a web server, but fast with PIX to the same web server)?
P.S. Addresses in attached picture config are not real, but I know what they translate to.

The connection to this server from the outside is perfectly fine, but access from inside users to the NAT'd IP which is 199.204.50.2/29 is having issues, however, access to the inside IP works fine (this part makes sense)Will It be a must to set the inside DNS A record to the inside IP and not the outside IP, or can users on the inside interface access the NAT'd IP which is assigned to the server

Cisco WAN :: NAT Inside-to-inside (hairpinning) With NVI On 887VA?
Nov 25, 2011I'm trying to configure hairpinning on my Cisco 887VA VDSL router, so all LAN users can connect to the server using SMTP port 25 which is also in the same LAN subnet, using external router address, which is assigned to dialer1 interface.Traffic comming in from outside works fine.
External IP: 1.1.1.1/29
PC address connecting to the server: 192.168.101.28
Server address: 192.168.101.200
IOS: 15.1.4M1
[code]....
I'm running tcpdump on the server on port 25 and... nothing happens. The traffic is not going through.One thing that I've notices in debug ip packet is this line:
s=1.1.1.1 (Vlan1), d=192.168.101.200 (Vlan1), len 52, rcvd local pkt
shouldn't source be internal vlan1 IP - 192.168.101.1?
