• ASA inside access DMZ and return

  Hi Expert,

  How configure ASA to allow access from the inside to dmz host and also back?

  Thank you.

  Rgds,

  To the Shaw feel Yeong

  Hello

  By default, access from inside the DMZ is permitted this access is through higher security level to lower the level of security.

  Return to inside host traffic is automatically granted by ASA/firewall if the connection / translation is valid / exists.

  Example:

  Inside of the intellectual property: 192.168.1.1/24

  DMZ: 172.16.1.1/24

  2 two ways to do:

  a. use nat & global command:

  Global (dmz) 1 172.16.1.10 - 172.16.1.20--> help de.10 a.20 will be used inside hosts to access dmz

  Global (dmz) 1 172.16.1.21--> all inside will use this IP like PAT, if the above range is fully used.

  NAT (inside) 1 192.168.1.0 255.255.255.0

  Note:

  -Use the ACL if you need to control the type of service to pass through and apply on the inside of the interface.

  b. static use of translation between inside and DMZ subnets:

  static (inside, dmz) 192.168.1 192.168.1.0 netmask 255.0.0.0

  Note:

  -This will allow inside the host to initiate & access dmz and dmz to initiate & access to the inside (initiate connection to dmz host). When DMZ accessing inside the host, DMZ use inside physics/assigned host IP.

  -Use the ACL if you need to control the type of service for cross and apply on time interfaces dmz & Interior.

  Example of configuration:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a00806745b8.shtml

  * Watch under command "static (inside the dmz).

• Client VPN on PIX needs to access DMZ

  VPN clients 3.5 ending PIX 6.X cannot access hosts on a PIX DMZ interface. Journal reports of error that there is no 'translation group available outside' for the subnet of the VPN Client (from the vpngroup pool).

  I should add the VPN client subnet to a nat (outside) device?

  Can I add it to the nat inside?

  Can I just add static to the DMZ hosts within the subnet interface because VPN clients can access the inside hosts?

  (I have the subnets in the nat 0 sheep ACL)

  Thanks and greetings

  JT

  You'll need to add is nat 0. You say in your () you have an acl sheep, for the perimeter network or the inside interface? You use the same access list to the sheep inside and dmz? You should separate if you use separate access list. Is your pool of client on a different subnet than your home network and dmz? It must be something like this:

  Customer IP local pool 192.168.1.1 - 192.168.1.254

  IP, add inside 10.10.10.1 255.255.255.0

  Add 10.10.20.1 dmz IP 255.255.255.0

  access-list sheep by 10.10.10.0 ip 255.255.255.0 192.168.1.0 255.255.255.0

  nonatdmz list of access by IP 10.10.20.0 255.255.255.0 192.168.1.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  NAT (dmz) 0-list of access nonatdmz

  If this is correct then clear x, wr mem, reload. I hope this helps.

  PS

  If he did not, only can recommend the upgrade your client and pix because that is exactly how it should look, and if its does not work you are facing an additional feature you want.

• ASA Site, Remote Site cannot access DMZ to the Hub site

  So I've been scratching my head and I just can't visualize what I what and how I want to do.

  Here is the overview of my network:

  Headquarters: ASA 5505

  Site1: ASA 5505

  Site2: ASA 5505

  Training3: ASA 5505

  All Sites are connected L2L to the location of the Headquarters with VPN Site to Site.

  Since the HQ site I can ping each location by satellite, and each satellite location I can ping the HQ site. I will also mention that all other traffic is also correctly.

  Here's my number: HQ site, I have a DMZ set up with a web/mail server. This mail/web server is accessible from my HQ LAN, but not from the satellite location. I need allow that.

  What should I do?

  My second question is that I want for satellite sites to see networks of eachother. I should create a VPN network between sites, or can this be solved in the same way that the question of the DMZ?

  I enclose the show run from my ASA HQ

  See the race HQ ASA

  For the mail/web server that requires access on the remote site VPN tunnels, you must add the servers to the acl crypto, similar to the way you have it for network access. Make sure that both parties have the ACL in mirror. If you're natting from the DMZ to the outside, make sure you create an exemption from nat from the dmz to the outside for VPN traffic.

  For the second question, because you have only three sites, I would recommend creating a tunnel from site to site between two satellite sites.

• Access DMZ, internal

  I use a PIX 506 6.1 (1) with such a DMZ. It's our first DMZ and I need assistance to access to the web server in the DMZ. We use a 172.16.0.0 subnet for the demilitarized zone and a 192.168.40.0 internal subnet. In 12.19.xxx.xx public subnet address. I added the following to the Web server on the PIX:

  static (dmz, external) 12.19.xxx.xx 172.16.0.21 netmask 255.255.255.255 0 0

  Global (dmz) 1 172.16.0.100 - 172.16.0.110

  NAT (dmz) 1 172.16.0.0 255.255.255.0

  I need to access the Web server in the DMZ to the 192.168.40.0 subnet.

  What Miss me? Thank you

• PIX 515E external SMTP and POP access DMZ

  Hi all

  I need help to solve the problem I am facing with the configuration.

  config: PIX515E Ver 6.3 (1), with 6 interfaces outside the interface is connected to the Internet router and assigned public IP. Access to the Internet is configured for users connected inside Interface only using the command Nat & Global (Global off-1 Interface). I want to activate the access to electronic mail (SMTP & POP3) host couple in one of the demilitarized zone.

  1 NAT configured on the interface & access list applied. If I allowed SMTP & POP only I even don't get a kick on the access list. If I have IP enable any of these hosts, I can surf the net, E-mail etc. After that when I restict to SMTP & POP only, it works for a while, after some time, I don't see any future success to the access list.

  What could the case of such behavior, I missing something...?, I'm confused.

  Thanks in advance.

  Best regards

  Ensure that you allow DNS from these hosts too (UDP/53), as they're going to do queries DNS for the remote host IP address and the domain MX record before they can establish a connection to the mail host relevant external.

  If you allow all IP then they will be able to make the DNS query, then perform the connection SMTP/POP, and they will be cached DNS queries for awhile that's why it works for a while after the removal of the ACL. Once the DNS cache expires in these hosts, they must make another DNS query causing crashes so that you don't have him through the ACL permits.

• ASA5500 - anyconnect VPN not access Web server in DMZ

  I am at a loss. I enclose my config. I can access DMZ from within the network, but cannot access DMZ of VPN.

  Any help would be great.

  Also have question access to management 0/0 (192.168.1.1) of the Interior of the E0/1 (192.168.2.0) network

  @richyanni1 ,

  For your VPN - DMZ problem, the following is the most likely cause of your problem:

  nat (inside,dmz) source static obj-dmz obj-dmz destination static obj-vpnpool obj-vpnpool

  You should have in place:

  nat (outside,dmz) source static obj-vpnpool obj-vpnpool static obj-dmz obj-dmz

  That's because VPN clients appear to come from the outside (to some purposes NAT) and the need to be exempt from NAT to access the resources of the DMZ. Management problems, the problem is asymmetric routing. When your packages arrive on the management UI, the ASA will try to send back traffic (starting with the 3-way TCP transfer protocol which will fail) through the inside interface but that won't work because ASA helped him, the source of the acknowledgement of receipt would SAA within the interface IP address, not the address of interface management in which the SYN sent. That's why most of the people have not historically used the management interface to ASA unless you have a real out-of-band network for management. Cisco recently introduced a separate fair management routing table, but you need to switch to 9.5 (1) or later to take advantage of that.

• LRT214 - routing of DMZ

  Hello

  for some reason I can't connect from the DMZ network to the internet.

  Installation program:

  Internal network: 192.168.0.0/255.255.255.0

  DMZ: 192.168.100.0/255.255.255.0

  WAN: connected to the cable-modem (DHCP)

  Even with the firewall disabled.

  So, for me, it seems that the unit is not "Routing" of the demilitarized zone.

  At the moment I activated the firewall again and added two rules to give them access DMZ:

  1 REFUSE all traffic to DMZ (any) to 192.168.0.0 - 192.168.0.255 (to deny access to the local network to DMZ)

  2 ALLOW all traffic to DMZ (any) to EVERYTHING (in order to select "WAN" here, would be great!)

  I had this problem before in the local network.

  But I could solve this problem when I switched the "operating mode" 'router' for 'bridge '.

  [Just a little note: after Linkysys support told me that the device if default!]

  BTW... so far, I found no clue about the difference between these two modes.

  Thanks a lot for your support

  Who was I had the suspicion on the VLan to.

  But I think that it is not completely right... you have a DMZ with a privat-ip-area, but these DMZ servers do not have access to internet (NAT number of DMZ in WAN) possible.

  To be honest, I find the DMZ - of the implementation of the very strange LRT214.

  No one expects such an implementation! And IMHO, this does not meet the definition of DMZ (see wikipedia).

• AnyConnect client can not access local network

  Hello

  I have a problem with the Cisco anyconnect. Once clients are connected they cannot access anything whatsoever, including their default gateway.

  Pool of the VPN client is on the same subnet as the LAN (139.16.1.x/24). Local network clients can access DMZ, VPN clients can ping computers on the local network, but they cannot access the DMZ.

  I guess that any rule providing that traffic is absent but I m new with Cisco ASA and I m totally lost. I read as much as I could on this topic, but I do not understand which rule is necessary.

  Thank you very much in advance for your support.

  Hello

  You don't have NAT exemption the DMZ network to the pool of VPN traffic.

  Please try to add the following statement to run:

  nat (DMZ,outside) 1  source static any any destination static NETWORK_OBJ_139.16.1.0_25 NETWORK_OBJ_139.16.1.0_25 route-lookup

  Also please delete the existing instruction manual nat "non-proxy-arp" statement, because it can cause problems like you the ip subnet address pool is identical to that of the Interior of the network.

  no nat (inside,outside) source static any any destination static NETWORK_OBJ_139.16.1.0_25 NETWORK_OBJ_139.16.1.0_25 no-proxy-arp route-lookup
  
  nat (inside,outside) 1 source static any any destination static NETWORK_OBJ_139.16.1.0_25 NETWORK_OBJ_139.16.1.0_25 route-lookup

• The ASA 5510 DMZ configuration

  I currently have an ASA 5510 with which I am configuring a HTTP/FTP host on a demilitarized zone. Currently the DMZ host is accessible outside but the hosts on the internal network can not access. I have a dedicated IP address for the host (1.1.1.228) DMZ and another IP for the PAT interface for internal clients (1.1.1.238). I know I'm missing a piece, either a statement nat() or a static(), please advise.

  The statement above will allow the host to access DMZ hosts inside using DMZ devices own IPs and vice versa.

  And, if necessary, use the ACL to restrict access to inside the DMZ, or DMZ inside.

  See you soon!

• Inside the interface of access IPSec on PIX

  Hi all

  I need advice with the following problem.

  I have PIX 515E with 3 interfaces inside.

  DMZ and outside, to 6.3 (3). Is it possible to access DMZ more inside the interface with IPSec of CISCO VPN client? IPSec creates a tunnel, the customer

  has a new address of the address pool, but

  in the paper, I have a message: not found translation etc... When I try to

  reach any device in the DMZ. The reason seems

  be with nat (dmz) 0, which should be inside the DMZ (social security social security 50 0). Even if I use nat (dmz) 0-list of remote access apart from it does not work. Any tips?

  Thank you

  Zdenek

  Hello

  Can you check if you are able to access the DMZ from the inside? If so, then u shud be able to access DMZ to connect remotely. This is because once the VPN client obtains the IP address of the inside pool, it's as good as he is in your home LAN. You can try putting inside DMZ natting... I mean put this command nat 0 because inside the DMZ, which will allow access to DMZ devices inside.

• PIX DMZ outward

  I have an intranet with 3 PIX 515 6.3 Firewall, exterior, Interior and DMZ interface.

  I want to access DMZ w/o NAT inside and outside, but want NAT to inside.

  the addresses are

  domestic 192.168.10.XX

  DMZ 197.28.10.xx

  outdoor 197.28.8.XX

  Need help.

  Have Web, FTP, and DNS on DMZ servers that must be available for outside and inside.

  Can you ping the web and ftp servers of either inside or outside? How does the PIX itself? Otherwise, I look at the routing configuration (i.e. the default gateway) on each one and check that you have all the IP addresses configured doubles. Check also for any software firewall on servers.

  Looks like you're closer...

  Hello

  I hope I can get this explained to me in simple terms so I understand what is happening. I thought that I had stated in my config that allowed all traffic of my internal networks to external networks, but my Active log is filled with packets are blocked and blocked. I'm just curious to know what is happening here. It is with UDP and TCP.

• 8.3 Cisco ASA VPN problem

  Hi all

  I have some problems with the implementation of a VPN using IPSEC to establish a connection from Site to Site.

  What I'm trying to Setup is the following, his IP address of a site can reach the beaches on site B and visa versa.

  Site A                                                       Site B

  192.168.10.0 172.16.0.0

  192.168.20.0 IPSEC tunnel - 172.17.0.0 -.

  192.168.30.0 172.18.0.0

  I tested with one subnet to another subnet that works. However, when I try to group the objects it fails.

  As an example I can set up a VPN of 192.168.20.0 to 172.18.0.0 that I can pass the traffic through but its unable to reach other subnets.

  Any advice would be greatly appreciated.

  Thank you.

  Andrew,

  Accroding to your config, each network is behind a different interface of the SAA, so you will need to change the NAT rule for each of them, for example:

  NAT (DMZ_Zone, outside) 1 static source ad-network-local ad-network-local destination static obj obj-remote control-remote control

  NAT (DB_Zone, outside) 1 static source local-network-db db-network-local destination static obj obj-remote control-remote control

  NAT (AD_Zone, outside) 1 static source local-network-dmz dmz LAN destination static obj obj-remote-distance

  Please review and give it a try.

  I hope hear from you soon.
