IPSEC VPN between Pix 515E and 1841 router
Hi all
BACKGROUND
We have implemented a site to site VPN IPSEC between a Pix 515E 8.0 operation (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and the ASDM the pix to build initial tunnels. Now the site with the router is evolving into a dynamic IP address from the ISP so we have implemented dynamic DNS to update dynamic IP address.
PROBLEM
The problem is that ASDM will not allow us to set a domain as the address of peers, it will not accept an IP address. We believe that the solution will be to remove the static Crypto map and replace it with a dynamic Crypto map on the side of Pix. Our questions are simply; is this the best solution? can change us the original static list or is it better to delete and make a new dynamic encryption card? Y at - it a shortcut to change the config command-line? This is a real network, so just check it out before make us any changes on the live kit.
Any help much appreciated.
You don't have to change anything when the peer-address changes. The dynamic crypto map aims to take dynamic peer connections. The only thing to remember, is that only the dynamic peer can initiate the connection. And you reduce your security if you use Pre-Shared key that now you can use a generic-PSK character.
As I remember, the PIX / ASA does not support the dynamic use of FQDNs for peer-resolution. This feature is supported in IOS.
For a feature, it would be preferable to static IP addresses on both sides.

IPSec VPN between Cisco ASA and Fortigate1000
Hello
I find a useful document on how to create a tunnel VPN IPSec with ASA 5510 firewall Fortigate 1000...
the configuration of the coast FG is done without any problem, BUT the document (. doc FG) said I must configure the ASA with a GRE interface and assign an internal IP address in order to communicate with the FG...
The question is: How do I configure the interface on the SAA ACCORD?
Thanks in advance, Experts...
Kind regards...
ASA firewall does not support the interface/GRE GRE tunnel.
If you need to have GRE configured, you will need to complete the GRE tunnel on router IOS.
If you want to configure just pure tunnel VPN IPSec (lan-to-lan), here is an example of configuration on the side of the ASA:
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080950890.shtml
Hope that helps.

If the RIP is not absolutely necessary for you, try adding the default route to R2:
IP route 0.0.0.0 0.0.0.0 172.16.2.1
If you want to use RIP much, add permissions ACL 102:

PPTP VPN between clients Windows and Cisco 2921 router
Hi all!
I have a problem with PPTP VPN between Windows clients and router Cisco 2921 with permission of RADIUS (IAS). When I try to connect to Cisco 2921 of Windows 7 by using MS-CHAP v2 I get the message 778: it was not possible to verify the identity of the server. Can I use PAP - power is OK. On Windows XP, the same situation.

I'll be very grateful for any useful suggestions
We had the same problem using MS-CHAP-V2 and 3945 router using IOS 15.2. When you add the same combination of username/password locally it worked fine but it wasn't no of course of the solution. We have solved this problem by adding the following line in the config file:
AAA authorization network default authenticated if
This is because Windows 2000 clients require the use of a statement of authorization aaa in the router config. Maybe it was default (and therefore not shown) previous iOS releases.
Success!

ASA 5505 - I can't create an IPSEC VPN between two ASA 5505
Hello
I have two ASA 5505 with basic license and I'm trying to create a VPN IPSEC using the CLI. Here are the steps I did:
1 Configure ASA-1 (host name, vlan 1 and vlan 2).
2. configure a static route
3. create object network (local and remote)
4. create the access list
5. create ikev1 crypto
6. create tunnel-group
7 Configure nat
and I repeat the steps above with the ASA but another change IP.
Are to correct the above steps?
Why can I not create an IPSEC VPN between devices?.
No, you needn't. The ASA configuration is ok. Packet trace proved it. I think it can be a problem on the hosts. Please, check the firewall on the PC and try to put out of service, if it is running.

Configure several IPSec VPN between Cisco routers
I would like to create multiple ipsec VPN between 3 routers. Before applying it, I would like to check on the config I wrote to see if it works. It's just on RouterA configuration for virtual private networks to RouterB, and RouterC.
As you can apply in a cyptomap by interface, I say with the roadmap, that it should be able to manage traffic for both routers. Or is there a better way to do it?

Hi Chris,
The two will remain active.
The configuration you have is for several ste VPN site is not for the redundant VPN.
The config for the redundant VPN is completely different allows so don't confuse is not with it.
In the redundant VPN configuration both peers are defined in the same card encryption.
Traffic that should be passed through the tunnel still depend on the access list, we call in the card encryption.
This access-lsist is firstly cheked and as a result, the traffic is passed through the correct tunnel
HTH!

Setting up a VPN between a WRVS4400N and ASA device
I'm a newbie when it comes to Cisco devices and I have a problem setting a VPN between a local and a seat some distance away.
Here, our local office, we have a device Cisco WRVS4400N Small Business.
At Headquarters, they have a feature of Cisco ASA.
We must set up a point to point VPN and I have no idea how to proceed with these devices.
To compound things, resources, I'm at the other end in an unknown entity that also does not seem to have a lot of experience with this.
Is there any type of step by step guide for such a configuration?
If not, can someone please help with this?
Hello William,.
I would call 1866-606-1866 Support Center for assistance on the side the tunnel then the entire side of the ASA WRVS has to do is match the settings. If the side ASA needs support with which we can transfer more TAC.

Thank you

If you see the MM_WAIT_MSG2, which means that her counterpart (the other side) does not answer and this side where you can see the status MM_WAIT_MSG2 sent the first message IKE, however, did not hear of the peer.
You can check if UDP/500 is stuck on the way between the 2 sites.
Try running traffic on the other side and see if you also get the same status of MM_WAIT_MSG2. If you do, that confirms 100% 500/UDP is blocked on the way between the 2 sites.

Yes, version PIX 6.3 does not support HS running nat or sh run crypto.
Please please post the complete config if you don't mind.
Please also try to send traffic between subnets 2 and get the output of:

PIX 515E and remote access VPN
I use a PIX 515E with: ASDM Version: 5,0000 51 PIX Version: 8.0 (4) and configure it with remote access VPN.
I would like to get an email every time that a user login (and or disconnection) to the VPN. Remote clients use the Cisco VPN Client.
Any help is appreciated,
Hello
Here is a link to the email configuration when you log in to the ASA/PIX: http://www.cisco.com/c/en/us/support/docs/security/pix-500-series-security-appliances/63884-config-asa-00.html#anc7
Then you can create a list of message to send the logs only for the connection/disconnection of the VPN user: http://www.cisco.com/c/en/us/support/docs/security/pix-500-series-security-appliances/63884-config-asa-00.html#anc18

I need to connect two offices (two different LAN) using routers cisco 1841 at both ends.
Currently the two cisco router are in working condition and refer the internet LAN clients. (making the NAT).
Can someone please tell us what is the easiest way to set up a VPN between two sites, so that LAN users to an office to access mail servers electronic/request to the office LAN.

Yes, you need a VPN site-to site. Start with this link which gives a number of examples to set up a VPN S2S between 2 routers Cisco.

IPSec Tunnel between Cisco 2801 and Netscren 50 with NAT and static
Hello
My problem isn't really the IPSec connection between two devices (it is already done...) But my problem is that I have a mail server on the site of Cisco, who have a static NAT from inside to outside. Due to the static NAT, I do not see the server in the VPN tunnel. I found a document that almost describes the problem:
"Configuration of a router IPSEC Tunnel private-to-private network with NAT and static" (Document ID 14144)
NAT takes place before the encryption verification!
In this document, the solution is 'routing policy' using the loopback interface. But, how can I handle this with the Netscreen firewall. Someone has an idea?
Thanks for any help
Best regards
Heiko
Hello
Try to change your static NAT with static NAT based policy.
That is to say the static NAT should not be applicable for VPN traffic
permissible static route map 1
corresponds to the IP 104
access-list 104 refuse host ip 10.1.110.10 10.1.0.0 255.255.0.0
access-list 104 allow the host ip 10.1.110.10 all
IP nat inside source static 10.1.110.10 81.222.33.90 map of static route

Client VPN Cisco ASA 5505 Cisco 1841 router
Hello. I'm doing a connection during a cisco vpn client and a vpn on one server asa 5505 behind a 1841 router (internet adsl2 + and NAT router).
My topology is almost as follows
customer - tunnel - 1841 - ASA - PC
ASA is the endpoint vpn (outside interface) device. I forward udp port 500 and 4500 on my router to the ASA and the tunnel rises. I exempt nat'ting on the asa and the router to the IP in dhcp vpn pool. I can connect to my tunnel but I can't "see" anything in the internal network. I allowed all traffic from the outside inwards buy from the ip vpn pool and I still send packets through the tunnel and I get nothing. I take a look at the statistics on the vpn client and I 2597 bytes (ping traffic) and there are no bytes. Any idea?
Where you you logged in when you took the "crypto ipsec to show his"? If this isn't the case then try again, also this option allows IPSEC over UDP 4500 and it is disabled, enable it.
ISAKMP nat-traversal crypto
Just enter the command as it is, then try to connect again after activation of this option and get the same result to see the.

VPN with ASA 5500 VPN with PIX 515E vs
I wonder what are the differences between the use of an exisitng PIX 515E for VPN remote users as appossed to acquire an ASA 5500 VPN remote users? Information or advice are appreciated to help me lean toward one or the other.
Craig
According to the version of the code that you run on the PIX on the PIX or ASA VPN features must be the same. So if the choice is not based on differences in features, what else would help guide the choice? You can consider if the existing PIX has sufficient resources to add the extra processing VPN load or if you should put that on another box. You might consider that the PIX is an older product range, and his end is near, while the ASA is the product that is the strategic replacement for the PIX. Given a choice I probably prefer to use a technology newer than the old technology. I also believe that the ASA will give you more choice of technology to go forward (a way of better growth) while the PIX provides current capacity but no path of growth.
On the other hand, there is the aspect of consider that using the existing PIX does not need not to buy something new and ASA would be an expense you have to cover in the budget. And for some people the budget constraint is an important consideration.
