  Where is the static nat translation, or configuration of port forwarding?

  you have bellows acl lines, these access lists is not yet applied to the external interface of the firewall.

  access-list extended 100 permit tcp any host 192.168.1.110 eq ftp
  access-list extended 100 permit tcp any host 192.168.1.110 eq ftp - data

  How the outside internet hosts are able to connect to a non-public such as the 192.168.1.110 IP address?

  you need little things to fix in your configuration, your external interface is first attributed to dynamic ip for ISPS to provide the public IP seen in your config like:

  interface Vlan2
  nameif outside
  security-level 0
  IP address dhcp setroute
  

  Number 1- because we don't know what address IP of the ISP dynamically given the firewall, you must know what address is provided by the show on the asa show ip interface brief command line and take notes on the IP Vlan2... that Ip address will be the use of a single for hosts on the internet so you can connect to your FTP 192.168.1.110 server.

  Number 2 - because you do not spared a public IP address to use a one-to-one translation NAT for your server ftp within a public IP to the outside address, you must use the keyword interface on your translation of static port and the real access list 100 for the firewall to allow this connection and sends the request to the server ftp inside.

  public static tcp (indoor, outdoor) interface 192.168.1.110 ftp ftp netmask 255.255.255.255
  public static tcp (indoor, outdoor) interface ftp - data 192.168.1.110 ftp - data netmask 255.255.255.255

  Then re - configure acl 100 as below and apply it to the external interface

  access-list extended 100 permit tcp any which interface outside eq ftp
  access-list extended 100 permit tcp any which interface outside eq ftp_data

  Access-group 100 in external interface

  Finally, make sure you have your FTP server is running, don't forget not that from outside you will be using the public IP address you got output show ip interface brief , which will be the IP address that will be used to FTP from the outside to the inside.

• 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.

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

• ASA 5505 8.41 dynamic configuration NAT NAT/static

  Hello

  I am having some problems of configuration statements NAT on my ASA5505 which has recently been upgraded to 8.41.

  I have a unique dynamic IP on the external interface of the ASA and wish that all internal hosts NAT/Pat it. In addition, I would like to have multiple ports 'sent' to internal hosts, one of which is TCP/4343. With the current configuration guests originate from the external interface correctly, but the service running on TCP/4343 is not accessible from the outside. See the output of the command below:

  exit "sh run object:

  network of the object DrJones
  Home 10.81.220.90
  network of the LAN object - 10.81.220.0
  10.81.220.0 subnet 255.255.255.0

  exit "sh run nat:

  network of the object DrJones
  NAT (inside, outside) interface static 4343 4343 tcp service
  network of the LAN object - 10.81.220.0
  NAT dynamic interface (indoor, outdoor)

  exit "sh run access-list":

  access extensive list ip 10.81.220.0 inside_access_in allow 255.255.255.0 any
  outside_access_in list extended access permit icmp any any echo response
  outside_access_in list extended access permit tcp any interface outside eq 4343

  Any help would be appreciated, if additional information is needed please let me know and I'll post it.

  Thank you in advance.

  Hi Mitch,

  There are two major changes between 8.3 - pre and post - 8.3.

  1 NAT

  2 interface Access-list.

  You went directly to step 1, but have set up the pre - 8.3 outside_access_in access list.

  The correct config would be:

  outside_access_in list extended access permit icmp any any echo-reply //you can remove this and add inspect icmp to the overall strategy.
  outside_access_in list extended access permit tcp any host 10.81.220.90 eq 4343

  8.3 and above, the access list interface should have the real ip and not the ip translated.

  I hope this helps.

• VPN on ASA-5510 with Configure a dynamic encryption card

  Hi all

  My name is ping, I have ASA-5510 for site to site VPN configuration, but am not clear with a few conifguration on ASA-5510 series, not sure on poin than, when I install on other sets of cisco router I can use

  ASA2 (config) #crypto card outside-card 10 ipsec-isakmp

  % NOTE: this new map encryption will remain disabled until a peer

  and a valid access list have been configured.

  ........

  but, when I configure ASA 5510 it as below:

  mtelcoASA2 (config) # crypto?

  set up the mode commands/options:

  CA Certification Authority

  dynamic-map set up a dynamic encryption card

  IPSec transform-set set, life of the IPSec Security Association and fragmentation

  ISAKMP configure ISAKMP

  main activities key long-term

  card to configure an encryption card

  ASA2 (config) # map outside-map 10 ipsec-isakmp crypto ?

  set up the mode commands/options:

  Entry dynamic is a dynamic map

  "Set up a dynamic crypto map" which uses for and why I can't use only "map outside-map 10 ipsec-isakmp crypto" and if not can't, can I skip this command or tell me the other way with explanation with nicely,

  Thank you very much

  hot topic,

  Ping,

  Just use crypto card outside-map 10 match/set without ipsec-isakmp key word and it will be fine.

• The ASA can use 2 dynamic cryptographic cards on the external interface?

  We have an ASA which is currently used with dynamic VPN. I don't know the pre-shared key.  If I was going to try to create another card encryption. I did not want to bring another drop.  I know that the router does not allow.  It would replace the existing info.  I wasn't sure of the SAA.

  David,

  The pre shared key is defined in the specific tunnel-group, not in the crypto map.

  tunnel-group ipsec-attributes

  pre-shared key cisco

  However, by default:

  Dynamics of LAN-to-LAN tunnels using the 'DefaultL2LGroup '.
  

  L2TP/IPsec connections use the 'DefaultRAGroup '.
  

  In order to see the pre shared key in clear text: "more system: run".

  You can have a single card dynamic encryption card crypto, but you can have multiple entries / map instances of this dynamic, for example:

  Crypto-map dynamic dynamic_map 10 the value transform-set ESP-AES-256-SHA
  

  Crypto-map dynamic dynamic_map 20 the value transform-set ESP-AES-192-SHA
  

  
  

  map outside_map 65535-isakmp ipsec crypto dynamic dynamic_map

  More info:

  Dynamic IPsec Tunnel between a statically addressed ASA and dynamically addressed Cisco IOS router that uses the example of Configuration of CCP

  ASA/PIX: Allow the tunneling split for the VPN Clients on the example of Configuration of ASA

  
  

  Let me know if you have any other questions.

• Cannot SSH in ASA after EZVPN configuration and do not specify "split-tunnel-political tunnelspecified.

  Even after the "split-tunnel-policy tunnelspecified" specification with "split-tunnel-network-list value TUNNEL of SPLITTING" and denying all traffic to the public IP address of the ASA, I'm still not able to SSH in the firewall. Everything else seems to work OK, but I have to be able to handle the ASA from the public interface. In fact, I expect little given the mean one sa is the installer for the tunnel, and it would seem that a deny statement would be ignored, but perhaps there is a way around this. Thank you.

  If you want to connect to your home IP through the tunnel, you must specify 'inside access management:

• VPN IPSEC ASA with counterpart with dynamic IP and certificates

  Hello!

  Someone please give me config the work of the ASA for ASA Site to Site IPSEC VPN with counterpart with dynamic IP and authentication certificates.

  He works with PSK authentication. But the connection landed at DefaultRAGroup instead of DefaultL2LGroup with certificate

  authentication.

  Should what special config I ask a DefaultRAGroup to activate the connection?

  Thank you!

  The ASA uses parts of the client cert DN to perform a tunnel-group  lookup to place the user in a group.  When "peer-id-validate req" is  defined the ASA also tries to compare the IKE ID (cert DN) with the  actual cert DN (also received in IKE negotiation), if the comparison  fails the connection fails. know you could set "peer-id-validate cert"  for the time being and the ASA will try to compare the values but allow  the connection if it cannot. 

  In general I would suggest using option "cert."

  With nocheck, we are simply not strict on IKE ID matchin the certificate, which is normally not a problem of security :-)

• ASA 5510 CLI Configuration

  Hello

  Is it possible to perform all the system configuration and management functions through the CLI at the Terminal?

  I think specifically to aspects such as the management of firewall rule configuration of the DHCP Service, VPN configuration, log review. etc etc.

  I have already done some configuration of the interface of base if the CLI, but want to know what depth, I can go.

  Thanks in advance.

  Paul

  The main thing that I know will have to be made through ASDM is manage bookmarks SSL VPN client and other pages.  All the other stuff you mentioned can be done through CLI.  I like to use a hybrid of CLI & ASDM when I managed firewalls.  I prefer to see the logs on the ASDM so, real-time log buffer is an excellent tool.
