EZ VPN on SAA
We have an ASA 5505 configured for EZ remote VPN. If assign us a static ip address for the external interface in our test lab, it remains standing. When we go out on the remote site, which has a FiOS connection with dhcp for the external interface address, it gives every hour. When we put a pix there, it remains standing. At sh crypto isakmp his on the side remote shows an AM_WAIT_MSG2 (when the SAA is in place and the tunnel fails) I have to restart the SAA, and then the tunnel will come back to the top. For an hour. Also has anyone seen this type of behavior? It has been very frustrating and I have a tac case, but they said that configuration seems fine.
Today is your lucky day. I had this problem with my ASA5505 on my FiOS connection. Apparently Verizon ping your device before it will allow you to request or renew your IP address. When your ASA comes first in line they can it ping because you have ICMP enabled outside and the VPN tunnel is not. Once the tunnel is established and you do not use the split tunneling, they can't ping your ASA. If you drop the tunnel the dhcp lease does not expire. What I had to do was the tunneling split on the vpn group that I used for the ASA and enable ICMP on the external interface. After that the ASA would stay for good.

Route Internet traffic against the default VPN on SAA route
I want to transfer all internet traffic to a VPN connection via the internal network and not divided the digging of tunnels or direct connection to the internet from the OUTSIDE interface.
I have a VPN connection default gateway, so all traffic is pushed back on the OUTSIDE interface when the VPN is in place and the user connects to the Internet.
Is it possible to send Internet traffic to the INSIDE interface, internal network, to route to the Internet.
I'm not looking for another solution, it's the design, I would like to implement.
As always, any help is greatly appreciated.
Of course you can, simply set the following text:
Route inside 0.0.0.0 0.0.0.0 in tunnel
The foregoing will force all VPN traffic after be decrypted to the next break of the SAA within the interface defined above

Refer to this link. There is an improvement that has been opened to support VPN filters in each direction, but it is not yet applied.
The only way I see is to modify the default behavior and configure ASA to submit VPN traffic to ACL interface using the command of not sysopt connection VPN-enabled and then configure ACL interface accordingly. I don't know if it's worth to you.

And this is done without L4-information (knowing that there are cases where this is done, but I do not see that in your scenario). And as said before, the filtering is performed using the vpn-filter.
Works for nat, you must use the correct order of the sentences-nat (descendant). So this Exemption-NAT must be above the general NAT for internet access. You can control that with 'see the nat.

Hello
Is there a difference between WebVPN and remote VPN access or they are the same.
Thank you.
access remote vpn consists of
-IPSEC VPN remote access. It is part of the ASA, no permit required, requires pre-installed Client from Cisco VPN IPSEC on PC
-with AnyConnect SSL VPN remote access. It requires licensing of SSL VPN on SAA. AnyConnect client can be installed automatically on the PC with the launch of web.
-with Essentials AnyConnect SSL VPN remote access. Beginning with ASA 8.2 (1), almost license $ 0. It's the same AnyConnect client as in the previous article, but it cannot be installed automatically with the launch of web. It must be previously installed as of Cisco IPSEC VPN client.
-webvpn aka clientless vpn. It is a portal HTTPS which allows HTTP connections, file sharing, telnet, RDP and much more (with smart tunnels) resources without having to install a real client on the PC. It requires licensing of SSL VPN on SAA. It cannot be used if "AnyConnect Essentials" license is activated on SAA after 8.2 (1)
Kind regards

Hi dude, I want to address this topic to understand ipsec VPN throughput.
I have 1 router 1921 and 1 ASA 5510 behind the router. I want to set up remote access on ASA firewall by traffic shaping router forwards (port UDP 500 and UDP 4500 port). I have 1 public IP address and I already configure NAT on the router. In fact, I heard that IPsec cannot pass through the NAT. So if I want to configure VPN on SAA, it is possible to do? All the guys comment on and propose your idea to me. Thanks for your reply.Hello
When you say, you have a public IP address. Is this address IP is assigned to the interface of the router or not attributed distinct IP address.
If its not assigned public IP address, you can make static NAT with ASA outside the IP address to a public IP address on your router as below
{100.100.x.x}fa0/0<-(R1)->fa0/1{192.168.100.1}<------->{192.168.100.2}eth0/0(ASA)eth0/1{172.16.01}
IP nat inside source 192.168.100.2 static 100.100.x.x
This way you have full IP to IP NAT.
If you got the only IP address that is assigned to the interface of the router then you will need to nat as port said
For VPN gateways running versions of the Cisco IOS software prior to version 12.2 (13) T, the functionality of IPSec passthrough is required on the router that runs PAT to enable payload ESP (Encapsulating Security) through.
Note: This feature is called IPSec through NAT (NAT) network support Advisory software (registered only customers).
In order to initiate the tunnel of the local counterpart (PATed), no configuration is necessary. In order to initiate the tunnel of the remote peer, these commands are needed:
IP nat inside source static esp inside_ip interface, interface
IP nat inside source udp static inside_ip 500 interface interface 500
For VPN gateways that run a version of the Cisco IOS software later than 12.2 (13) T, IPSec traffic is encapsulated in data protocol packets UDP (User) port 4500. This feature is called IPSec NAT transparency . In order to initiate the tunnel of the local counterpart (PATed), no configuration is necessary.
In order to initiate the tunnel of the remote peer, these commands are needed:
IP nat inside source udp static inside_ip 4500 4500 interface interface
IP nat inside source udp static inside_ip 500 interface interface 500

Host NAT clientless VPN access
Hello
I have an ASA 5520 with a DMZ server accessible from the internet and local network using the public IP (static NAT to the DMZ server). As VPN users can access this server using the address public IP send the addresses of public subnet to the remote users with split tunneling ACL. The problem is that we need Clientless Remote Access users for this server attacker still sound too and it does not work. It works just fine when Clientless Remote users access to the private address of the DMZ server. We all need to connect to this server again a public address for the code page for the web server.
I can't use split tunnel for Clientless Remote users, and connection was apparently the ASA as the source for this traffic. Anyone know if it is possible or an idea of what can I test?
Thank you
Kind regards
Unfortunately, this is not possible for clientless VPN, the SAA is the connection of transmission by proxy because it isn't a full VPN tunnel. Therefore, it can only proxy the connection on the actual address, and not the address using a NAT.

Y at - it a client AnyConnect VPN for Windows Mobile 6.5
Hi people,
I have a client using PDA based on Windows Mobile 6.5 and Windows CE. Is there a version of the AnyConnect VPN client for these devicese and in this case, where they are available for download?
Best regards

Hi Peter,.
There isn't a client available for mobile platforms. However, perhaps, they may work with SSL VPN on SAA... But however the browsers on these platforms are obsolete... (like BONE :-))

L2TP Windows 7, split and site-to-site tunnel
Hi all
I'm going to this interesting problem that drives me crazy all day. I have ASA 5505 (ver 9) where I set up VPN site-to-site to another router and it works. Then I configured L2TP IPsec VPN on SAA with split tunneling, and I can reach my local network. The problem is when I am trying to reach this remote network that is behind this site-to-site VPN. Whatever I do, I'm not able to reach the network. This exact same setup works on different ASA with AnyConnect VPN.
So that's what I did:
(1) adds VPN subnet as ITS 2nd to the existing site-to-site VPN
(2) exemption from NAT configured for subnet VPN when you go to the remote subnet
(3) published the remote subnet to VPN client.
This should do the trick as it does when AnyConnect is in question.
I'll paste some commands concerning:

Hello, Damir Reic.
What do you use NAT for L2TP-VPN? Split tunneling is help your users internet direcrly so you don't need to use NAT. It can be a source of problem as NAT works before VPN site to site. If your remote users traffic could be changed to NAT and IP traffic that wi source address will be different. And for this reason, it is not rules hiting your site-to-site VPN.

(Q) ping remote ip unable on ASA is not Firewall not on pc (VPN site to site on SAA) configired no proxy, icmp not inspect, no chance
Note - I can ping PC but not the same subnet ip on ASA2 L3
PC---> > ASA1 - ASA2<>
Hi Matt,
Let me answer your question in two points:
- You cannot ping an ASA on another interface other than the one where you are connected to the ASA of.
For example, ASA1 and ASA2 are connected through their interfaces 'outside '. ASA1 (or any other device on the external interface) can not ping/access ASA2 on his (ASA2) within the interface. The only time wherever this can be substituted is a tunnel VPN with the command "access management" configured for other interface, for example management-access inside
- Traffic ASA1 ping to a remote client behind ASA2 won't over the VPN tunnel and as such is not encrypted. That's because ASA1 will forward traffic based on its routing table that probably this way through its 'outside' interface Except that traffic is allowed with the ASA2 (using the ACL), it will fail.
We can do on the routers of sourcing our ping to another interface, but it will not work on the SAA.

Dynamic VPN for a SAA with IP tunnel
Hi community.
Can someone please send a simple configuration for a SAA with dynamic IP connected to an ASA with a static IP address. I read some manuals and how to. But neither works with my ASA. All the how to are older versions of software, I use softwareversion 9.0.
Do you need a config tunnel and political group for the ASA for dynamic IP and static IP ASA.
Thanks in advance and greetings patrick
Hello
Maybe that this document could help or have you already had a look?
http://www.Cisco.com/en/us/products/ps6120/products_tech_note09186a0080bc7d13.shtml
It gives simple examples of HUB with a static public IP address and 2 sites of TALKING with dynamic public IP address. Cisco ASA and Cisco router:
In my work I rarely run in the situation where I have to configure VPNS between sites, while the other site has a dynamic IP address. Although the situations that I met were conducted using an ASA5505 as a hardware network Extension Mode client.
I should really lab installation documents a day before me also.

Unique password on SAA for VPN access
Hello
It is posibble create a unique password on SAA for VPN access?
I googled a bit and found a few solutions with unique servers from other suppliers.
I wonder if this is possible without additional hardware/software.
Hello
you will need to integrate the VPN with the RSA. they will give you once the configuration of the password tokenized soft or hard token.
Outside of RSA, there is no other choice I guess.
I hope this helps.
Kind regards
Anisha.

Just to confirm that the VPN endpoint must be on a physical interface on a SAA
I have a client who changes their public IP address range, currently the FORMER IP exists on the physical Interface Internet and the NEW is the ASA, to be able to use the NEW IP to the endpoint of the VPN, it must be on a physical interface, so I think having a trunk to the Internet router, so that the NEW can have a physical address.then IP can pass another on the NEW for VPN.
Hi Richard,
Yes, it must be on a physical interface. Because you cannot configure secondary ip on the ASA, the only approach I can think of, is to set up a trunk according to your suggestion. Unless you use a proxy-arp :).
