HOW connection NAT on ASA 5505
Hello guys
first of all, thank fully any community of cisco, they helped me a lot withouth expert and University...
Today, I have some question on NAT
We HAVE site-to-site VPN, his job very well. our company demand of patern to use the public Ip address instead of the ip address private field of encryption. and they said, you have to NAT for you the private to the PUblic ip address. really, we don't know how NAT for cisco ASA 5505.
THIS IS THE CASE
OUR COMPANY = USES CISCO ASA 5505
OUR PUBLIC IP ADDRESS: 155.155.1555.20
PRIVATE IP: 192.168.7.2 SOUND LINUX SERVER, THEN HOW WE CAN NAT THIS IP PRIVATE AND CHANGE IN PUBLIC
Thank you very much
If you have 1 public IP address and it is assigned to your ASA outside interface, then you need to configure static PAT (you will need to know what exactly they want to access and configure the specific port they need).
However, if you have a free public IP address, then you need not to know exactly what they need to get to and you can configure the linux server using the public IP to spare.
Also, they need access to the linux server using public IP via the VPN tunnel (encrypted)? or they are happy to access only via the internet (clear text)?

How much of VLAN asa 5505 security plus support
Hello guys. I have asa 5505 Adaptive Security more. and I have only 3 VLAN. outside, inside, restricted DMZ.
If it works well, but I want to connect my inside another private network, so please can someone help me out here. or I have to buy a license.
and how can I activate the license key
Thank you very much
Here is the explanation since I have no idea about your topology.
The devices allowed for this platform:
The maximum physical Interfaces: 8
VLAN: 3, restricted DMZ
Inside guests:10
Failover: disabled
VPN - A: enabled
VPN-3DES-AES: enabled
Peer VPN: 10
WebVPN peers: 2
Double ISP: disabled
Junction ports VLAN: 0
This platform includes a basic license.
Here is an example of the license feature set more security:
The devices allowed for this platform:
The maximum physical Interfaces: 8
VLAN: 20, unrestricted DMZ
The hosts on the inside: unlimited
Failover: Active / standby
VPN - A: enabled
VPN-3DES-AES: enabled
VPN peer: 25
WebVPN peers: 2
Two Internet service providers: enabled
VLAN Trunk Ports: 8This platform includes an ASA 5505 Security Plus license.
No explanation for DMZ limited.
- Only 10 of the hosts in the DMZ and LAN combined may contacted outside interface at any time.
- Only 2 VLAN fully functional (inside and outside generally) are allowed. The 3rd VLAN, usually a demilitarized zone can only be activated with the command 'no attacking vlan n'that prevents connections to one of the other VLANS, usually inside
Just in case where if you have basic servers then put inside dmz connections do not allow. If you have more security then should not be any problem. As you mentioned on the IP ranges vlan if all belong to the inside and then connecting with outside shouldn't be a problem.
Thank you

Connection refused because of the failure of path opposite of that of NAT
I put a second location of ASA and not can communicate through the VPN is implemented. The error I get is (rules asymmetrical NAT matched for flows forward and backward; Connection for icmp outside CBC: 192.168.72.14 internal dst: 192.168.73.103 (type 0, code 0) rejected due to the failure of reverse NAT) when trying to ping a host on the network iinsde the 73 to a host within the network of 72.I mirrored the statements of nat VPN work. I see an ACL to a group of objects but don't see where this is important. Am I missing something obvious?

can you try to change the transformation of dynamic value ESP-3DES-SHA map.
for example
remove the encryption scheme dynamic-map outside_dyn_map 20 transform-set TRANS_ESP_3DES_MD5
and replace with
Crypto-map dynamic outside_dyn_map 20 the value transform-set ESP-3DES-SHA

Internet VERY slow connection on SD2008 connected to ASA 5505
I recently bought a SD2008 (2008/11/28) to replace an older Linksys 10/100 switch for my home network. This switch connects to an ASA 5505 to go to the internet. I have improved since most of my pc have 10/100/1000 and the new NAS I purchased also connects to 1000 so I wanted to speed internally.
The cries of network domestic now
BUT...
Get out to the internet has now slowed to crawl of a lily "slowski". I used to get 16-18Mbps using the 10/100 switch. Now, I'm lucky to get 1 MB/s dl speed.
Any suggestions would be greatly appreciated.
Too bad. I found the answer on a completely different thread that actually worked. I've linked the SD2008 to the ASA 5505 with a crossover cable, set the port speed/duplex AUTO/AUTO, restarted the ASA, and everything was back to normal.
So much for the detection of cut MDI/MDI-X auto...
Hope this helps someone else.

Problem with ASA 5505 VPN remote access
After about 1 year to have the VPN Client from Cisco connection to an ASA 5505 with no problems, all of a sudden one day it stops working. The customer is able to get a connection to the ASA and browse the local network for only about 30 seconds after the connection. After that, no access is available to the network behind the ASA. I have tried everything I can think of to try to solve the problem, but at this point, I'm just banging my head against a wall. Anyone know what could cause this?
Here is the cfg running of the ASA

SCP behind the ASA 5505 may not help ping an internet address,.
There must be a problem of ACL configuration. How to configure the ASA 5505 so that computers
behind an internet can ping 4.2.2.2 such IP address or www.google.com.
Thank you
David
If you have no ACLs on the external interface, please use the following command to allow ICMP through the ASA.
fixup protocol icmp.
So try and ping. Let me know if this helps.
Also, please give us a little more in detail so that we can understand and help you better
See you soon,.

ASA 5505 as internet gateway (must reverse NAT)
Hi all the Cisco guru
I have this diet:
Office-> Cisco 877-> Internet-> ASA 5505-> remote network
Office network: 192.168.10.0/24
Cisco 877 IP internal: 192.168.10.200
Cisco 877 external IP: a.a.a.a
ASA 5505 external IP: b.b.b.b
ASA 5505 internal IP: 192.168.1.3 and 192.168.17.3
Remote network: 192.168.17.0/24 and 192.168.1.0/24
VPN tunnel is OK and more. I have the Office Access to the remote network and the remote network access to the bureau by the tunnel.
But when I try to access the network remotely (there are 2 VLANS: management and OLD-private) to the internet, ASA answer me:
305013 *. * NAT rules asymetrique.64.9 matched 53 for flows forward and backward; Connection for udp src OLD-Private:192.168.17.138/59949 dst WAN:*.*.64.9/53 refused due to path failure reverse that of NAT
Ping of OLD-private interface to google result:

Result of traceroute
How can I fix reverse NAT and make ASA as internet gateway?
There is my full config

Why you use this NAT type?
Access extensive list ip 192.168.17.0 WAN_nat0_outbound allow 255.255.255.0 any
NAT (OLD-private) 0-list of access WAN_nat0_outboundYou are basically saying the ASA not NAT traffic. This private IP address range is not routed on the Internet. This traffic is destined to be sent over the Internet? If so, that LAC should then not be there.
If you want NAT traffic to one IP public outside the ASA, you must remove this line and let the NAT and GLOBAL work:

Strange behavior of NAT ASA 5505
Hello
We have an ASA 5505 version 9.1 (5) and we need to open port TCP 55055 firewall that redirect to TCP port 80 on ip QNAP Viostor 192.168.11.254
I added a network object in this way:
The Viostor object network
Home 192.168.11.54
Description QNAP_Viostor
NAT rule:
NAT (inside, outside) interface static service tcp 80 55055
Firewall rule:
access-list outside_access_in line 8 Note Viostor
allowed to Access-list outside_access_in line 9 extended tcp any Viostor eq 55055 object
When I try to connect with the application Android Vmobile I see that notify the journal of the ASA:
Request TCP and eliminated from MY_EXTERNAL_IP to outside:X.Y:Z.W/55055
The ASA has no server UDP which serves the UDP request
I don't understand why UDP instead of TCP.
Please help me!
Thank you
Ahmed, thanks for your replies... However're missing you something important (sw ASA version). Tracer package shows THAT NAT is not affected; and on this sw version ACL does not use external_IP or mapped IP, but the real_IP instead.
s.be00001, follow these steps:

Run the packet - trace and send us the results:packet-tracer input outside tcp 8.8.8.8 1025 [outside interface IP] 55055 detailed

VPN IPSec passthrough ASA 5505 (v9.2.4) - connected but no access
Hello
Here's my situation:
I am trying to connect a client IPSec VPN via an ASA 5505 to an other ASA 5505. In fact, I can make the connection to the VPN but all accesses are blocked (ping or IP access).
When I use a router ISP directly or at home, I have no problem (ping and IP access follow the firewall rules). Connection and access are allowed.
Schema:
I have attached both the configuration for this post
I've recently updated 8.2.5 ASA 8.4.6 and 9.2.4. An another ASA 5505 v8.2.5 works well in both way (via ASA VPN connection) and the VPN through ASA1 this ASA.
I have tried many solution to solve the problem (nat/ipsec static inspection), but I failed to solve it. I tried to see asp in ASA1 drop, but I was right to drop only "nat-xlate-failed".
Thanks for your help because I'm going crazy...
Olivier,
PS: Sorry for my English...
Hi Olivier,.
Could enable you icmp on the ASA inspection?
Use this command and check:
fixup protocol icmp

connect Cisco VPN client v5 to asa 5505
I have remote vpn configuration issues between ASA5505 and Cisco VPN client v5. Successfully, I can establish a connection between the client Vpn and ASA and receive the IP address of the ASA. Statistical customer VPN windows shows that packets are sent and encrypted but none of the packages is received/decrypted.
Cannot ping asa 5505
Any ideas on what I missed?
Try adding...
ISAKMP nat-traversal crypto
In addition, you cannot ping the inside interface of the ASA vpn without this command...

Ikev1 ASA 5505 VPN connection error
Hello
I had previously defined our VPN using IPsec on our ASA 5505 via the ASDM. It was workign fine until an outtage power loses my settings on the device. (possibly a recording of order is not pressed)
Now when I try and put in place, once again I am recieveing an error to port binding. I have configured as normal using the wizard and activate split defintion and exempt the network inside.
The isssue when you apply the settings that I get is:
"[ERROR] crypto ikev 1 activate outdoors.
IkevReceiverInit, cannot bind the port. "
When I try to connect to the VPN I then get an error "the server cannot be reached" or something similar to that...
Could someone please shed some light on what can cause this problem?
Best regards, the Paris
William.
Hello
Thanks for the information!
We will need to know why this host using UDP 4500 and if this host really needs to use this port.
What type of application is running on this host?
What is a host internal or external?
You may also block the host on the SAA on the incoming interface to avoid the use of the UDP 4500 port using a group of access (outside or inside). Don't forget that you will need a ip to allow a at the end of the ACL to avoid any problems. Another option would be to use IKEv1/IPsec over TCP
IKEv1/IPsec over TCP allows a Cisco VPN client operate in an environment in which IKEv1 or standard ESP may not work or may work only with the change of the existing firewall rules. IPsec over TCP encapsulates IPsec protocols both IKEv1 in a TCP packet as and allows a tunnel secure two firewalls and NAT and PAT devices. This feature is disabled by default.
The default port is 10000.
HostName (config) # ikev1 crypto ipsec-over-tcp
You also need to activate on the VPN client under the profile.
Change > Transport > IPSec over TCP.
I hope this helps.

ASA 5505 Anyconnect traversal nat error
Good afternoon gents,
I installed an ASA 5505 and can connect with anyconnect, but when I do, I can't access my LAN, then my LAN can access my laptop. In the newspapers, I see the following error message:

ASA 5505 AnyConnect 8.2 connect other subnets from site to site
Hello
I'm somehwat new Cisco and routing. I have an installation of two ASA 5505 that are configured for the site to site vpn and AnyConnect. The AnyConnect subnet can connect to inside VLANs to the SiteA but I can't for the remote to Site B subnet when you use AnyConnect. Any ideas? I have to add the subnet of 10.0.7.0/24 to the site to site policy? Do I need to set up several NAT rules? Details below.
Site A: ASA 5505 8.2
Outside: 173.X.X.X/30
Inside: 10.0.5.0/24
AnyConnect: 10.0.7.0/24
Site b: ASA 5505 8.2
Outsdie: 173.X.X.X/30
Inside: 10.0.6.0/24
The AnyConnect subnet cannot access the network of 10.0.6.0/24.
Any help would be greatly appreciated! Thank you!
Hello Kevin,
You must go back to identity (outdoors, outdoor) identity NAT (essentially for two subnets (Anyconnect and Remote_IPSec).
And of course to include traffic in the ACL for IPSec crypto and (if used) split with the Anyconnect tunnel.
Note all useful posts!
Kind regards

Hi, we purcahsed a new ASA 5505 and try to configure IPSEC VPN via ASDM; I simply run the wizards, installation vpnpool, split tunnelling, etc.
I can connect to the ASA using the cisco VPN client and internet works fine on the local PC, but it can not access the local network (can not impossible. ping remote desktop). I tried the same thing on our Production ASA(those have both Remote VPN and Site-to-site VPN working), the new profile, I created worked very well.
Here is my setup, wrong set up anything?
