ISAKMP for vpn

to my knowledge, I think that pix & asa allow ipsec to be attempted (or possibly put in place) from anywhere.

I read that, but could not understand what he entirely & there is no mention of avoid it.

If it does not attempt, can she really be established even if this peer is not mentioned in sets related ipsec vpn.

If there is such a condition, how can it be configured to accept ipsec still started from only a specific public source.

appreciate your help.

Thank you.

Hello

ASAs the PIX allow any source IPsec connections (if properly configured).

For example, as soon as the PIX / ASA is configured as a VPN IPsec server, it will allow connections from any source on the Internet.

I guess that since the main purpose of remote VPN access must be able to connect from anywhere, this is the behavior.

The ASAs now include an option to apply the ACL on the interface of traffic to employment (as well as the traffic through the box).

If you apply that ACL ISAKMP only from a certain IP address (or the refusal of certain IP,) then the ASA will follow this rule, but this is not often used because it defeats the purpose of being able to connect from anywhere.

The security normally applied for remote connections is through the name of user and password, OTP, digital certificates, etc. to validate the authenticity of the user trying to connect. In addition, you can use Secure Desktop to do a posture check of the remote device and allow connections only if certain conditions are met.

However, if you are referring to VPN Site to Site, the PIX / ASA allows only a valid counterpart (already configured IP) connections.

It will be useful.

    Hello

    For me, it looks like it has configured the route correctly;

    ip route 0.0.0.0 0.0.0.0 fastethernet4 -> for all traffic to the internet.

    Road 10.1.0.0 ip 255.255.255.0 Dialer1 -> for vpn traffic to HO.

    The public_IP_HO must be defined according to the map of encryption using the set by the peers command.

    I want to add is on the isakmp policy hash attribute, you can choose between sha/md5 or whatever available on your device. Make sure that the isakmp policy to match political isakmp of your HO.

    The other thing is the acl for the internet. You may want to consider replacing the deny statement if you want to deny traffic only to your jar currently it is said to deny all traffic 10.10.100.0 10.0.0.0 network, not to the 10.1.0.0 HO (network).

  • ASA - several IPS for VPN

    I'll put up Anyconnect to replace our customers of Cisco IPsec VPN, since it is end of life. A part of the process is to get an SSL certificate and a FULL domain name to use for this. I've got that and it is applied to the ASA very well. Now we don't get these warnings to the subject it is not not sure and such.

    The problem is that we use a non-standard port for the SSL VPN from 443 is already sent to an internal device. I have unused public addresses to the external interface of the ASA, but I don't know how I could use them. I would like to have a different IP address for SSL VPN, so I don't have to mess with the port forward that is currently in place. I read on proxy arp, but that looks like it could be a problem. I could have someone connect another cable to a different interface on the ASA (5512-X) and assign this static interface I want for the VPN, but I'm not sure it will work well. We have connections VPN site to site in place as well. Can I have the ASA listening on two different interfaces at the same time?

    Recap:

    IP 1 - address primary NAT, Site at tunnels put end here, some Cisco IPsec VPN terminate customer

    IP 2 - want to have all customers of Anyconnect connect here, to migrate all legacy Cissco IPsec clients until they are all over Anyconnect.

    Key is that I can not stop listening on IP 1 for site-to-site connections.

    Thoughts?

    Thank you!

    On the SAA, you cannot use the additional IPS for VPN.

    If tcp/443 is already used for an external server, then I would reconfigure the DNS entry for it to use the second IP address that must be sent to the internal server. You can then use the IP interface of the ASA for AnyConnect.

  • Can the NAT of ASA configuration for vpn local pool

    We have a group of tunnel remote ipsec, clients address pool use 172.18.33.0/24 which setup from command "ip local pool. The remote cliens must use full ipsec tunnel.

    Because of IP overlap or route number, we would like to NAT this local basin of 172.18.33.0 to 192.168.3.0 subnet when vpn users access certain servers or subnet via external interface of the ASA.  I have nat mapping address command from an interface to another interface of Armi. The pool local vpn is not behind any physical interface of the ASA. My question is can ASA policy NAT configuration for vpn local pool.  If so, how to set up this NAT.

    Thank you

    Haiying

    Elijah,

    NAT_VPNClients ip 172.18.33.0 access list allow 255.255.255.0 10.1.1.0 255.255.255.0

    public static 192.168.33.0 (external, outside) - NAT_VPNClients access list

    The above configuration will be NAT 172.18.33.0/24 to 192.168.33.0/24 when you go to 10.1.1.0/24 (assuming that 10.1.1.0/24 is your subnet of servers).

    To allow the ASA to redirect rewritten traffic the same interface in which he receive, you must also order:

  • Policy NAT for VPN L2L

    Summary:

    We strive to establish a two-way VPN L2L tunnel with a partner. VPN traffic is one-to-many towards our partner, and our partner they need of a many-to-one to us (they need to access a host on our network). In addition, our partner has many VPN, so they force us to use a separate NAT with two private hosts addresses, one for each direction of the tunnel.

    My initial configuration of the tunnel on my grown up side of Phase 1, but not IPSec. Partner ran debug that revealed that my host did not address NAT'd in the NAT policy. We use an ASA5520, ver 7.0.

    Here is the config:

    # #List of OUR guests

    the OURHosts object-group network

    network-host 192.168.x.y object

    # Hosts PARTNER #List

    the PARTNERHosts object-group network

    network-host 10.2.a.b object

    ###ACL for NAT

    # Many - to - many outgoing

    access-list extended NAT2 allowed ip object-group OURHosts-group of objects PARTNERHosts

    # One - to - many incoming

    VIH3 list extended access permit ip host 192.168.c.d PARTNERHosts object-group

    # #NAT

    NAT (INSIDE) 2-list of access NAT2

    NAT (OUTSIDE) 2 172.20.n.0

    NAT (INSIDE) 3 access-list VIH3

    NAT (OUTSIDE) 3 172.20.n.1

    # #ACL for VPN

    access list permits extended VPN ip object-group objects PARTNERHosts OURHosts-group

    access allowed extended VPN ip host 192.168.c.d PARTNERHosts object-group list

    # #Tunnel

    tunnel-group type ipsec-l2l

    card <#>crypto is the VPN address

    card crypto <#>the value transform-set VPN

    card <#>crypto defined peer

    I realize that the ACL for the VPN should read:

    access allowed extended VPN ip host 172.20.n.0 PARTNERHosts object-group list

    access allowed extended VPN ip host 172.20.n.1 PARTNERHosts object-group list

    .. . If the NAT was working properly, but when this ACL is used, Phase 1 is not even negotiating, so I know the NAT is never translated.

    What am I missing to NAT guests for 172.20 addresses host trying to access their internal addresses via the VPN?

    Thanks in advance.

    Here is the order of operations for NAT on the firewall:

    1 nat 0-list of access (free from nat)

    2. match the existing xlates

    3. match the static controls

    a. static NAT with no access list

    b. static PAT with no access list

    4. match orders nat

    a. nat [id] access-list (first match)

    b. nat [id] [address] [mask] (best match)

    i. If the ID is 0, create an xlate identity

    II. use global pool for dynamic NAT

    III. use global dynamic pool for PAT

    If you can try

    (1) a static NAT with an access list that will have priority on instruction of dynamic NAT

    (2) as you can see on 4A it uses first match with NAT and access list so theoretically Exchange autour should do the trick.

    I don't see any negative consequences? -Well Yes, you could lose all connectivity. I don't think that will happen, but I can't promise if you do absolutely not this after-hours.

  • AAA for VPN - Kerberos, LDAP or an NT domain?

    All,

    After that a small return on what you think is the best method for AAA authentication for VPN clients when authenticating against a Windows domain for remote access?

    I have always used "NT Domain" because it seems to correspond roughly to the NT Auth I used to use on the old hubs. However, I (finally) decided to take a look at the Kerberos and LDAP, since they must have been added for a reason...

    Far as I can tell LDAP adds the ability to search a little more finely (basic DN) AD, but that's all. Am I missing something? Are there more reason to use LDAP or Kerberos domain auth?

    What is more reliable? That you guys use?

    See you soon!

    Either it is reliable, you can map users in different group policies or apply different DAP political, based on their belonging to a group. If you are basic authentication, then your method is still the best way to go.

  • Traffic permitted only one-way for VPN-connected computers

    Hello

    I currently have an ASA 5505.  I put up as a remote SSL VPN access.

    No worries

    As we change the config I would do as well as possible.

    First, it is strongly recommended to use a different range of IP addresses for VPN clients and the internal network

    No VPN_Pool 192.168.250.100 - 192.168.250.101 255.255.255.0 ip local pool mask

    mask 192.168.251.100 - 192.168.251.101 255.255.255.0 IP local pool VPN_Pool

    NAT_0 ip 192.168.250.0 access list allow 255.255.255.0 192.168.251.0 255.255.255.0

    NAT (inside) 0-list of access NAT_0

    Then give it a try and it work note this post hehe

  • Limit bandwidth for VPN users

    Hi guys,.

    I use ASA Version 8.2 (1), I want to limit vpn users to use less bandwidth of my Interlink to access something on the inside of the network

    example: source vpn pool

    Destn: inside the network

    Please let me know how to achieve this with QOS config.

    Hello

    Probably the best would be to match groups of tunnel.

    class-map TG1-best-effort 
    match tunnel-group Tunnel-Group-1 
    match flow ip destination-address 

    Then this traffic in police policy-map and apply the service policy to the external interface (since you want to traffic police from your home). You can also use the pool for vpn access lists.

    For more details, please see:

    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.

  • Dynamic routing for VPN Failover L2L

    Hello

    Can someone offer me some advice on this please?

    I have attached a simple diagram of our EXTENSIVE referral network.

    Overview

    • The firewall is ASA 5510 running 8.4 (9)
    • Basic to the Headquarters network uses OSPF
    • On ASA static routes are redistributed into OSPF
    • On ASA for VPN static routes are redistributed into OSPF with 130 metric so redistributed BGP routes are preferred
    • Basic network has a static route to 10.0.0.0/8 to Corporate WAN, which is redistributed into OSPF
    • Branch Office WAN uses BGP - routes are redistributed into OSPF
    • The branch routers using VRRP for redundancy of the IP for the default gateway of local customers.
    • Branch router main past off VRRP IP to router backup when the WAN interface is down
    • BO backup router (. 253) contains only a default route to the internet
    • In normal operation, the traffic to and from BO uses Local Branch Office WAN
    • If local BO WAN link fails, traffic to and from the BO uses IPSec VPN via public Internet

    I try to configure dynamic routing on our network for when a branch switches to the IPsec VPN. What I want to happen (not sure if it is possible) is for the ASA announce the subnet to the remote end of the VPN in OSPF to Headquarters.

    I managed to get this working using IPP, but for some reason any VPN stay up all the time when we are not in a failover scenario. This causes the ASA added the table as a static route is the remote subnet in it and do not use the announced route of OSPF from the core network. This prevents the BO customers access to the Internet. If I remove the IPP on the VPN setting, ASA learns the route to the subnet via the WAN BO - resumes normal operation.

    I have configured the metric of the static routes that get redistributed into OSPF by ASA superior to 110. This is so that the routes redistributed by the WAN BO OSPF BGP, are preferred. The idea being that when the WAN link is again available, the routing changes automatically and the site fails to WAN BO.

    I guess what I need to know is; This design is feasible, and if so where I'm going wrong?

    Thank you

    Paul

    Hi Paul,.

    your ASA maintains the tunnel alive only because this path exists on ASA.  This is why you must use IP - SLA on ASA to push network taffic "10.10.10.0/24" based on the echo response, using the ALS-intellectual property

    Please look at the example below, in the example below shows that the traffic flows through the tunnel, only if the ASA cannot reach the 10.10.10.0/24 network via the internal network of HQ.

    This configuration illuminate ASA.

    Route inside 10.10.10.0 255.255.2550 10.0.0.2 track 10

    (assuming 10.0.0.2 ip peering from inside the ip address of the router to HO)

    Route outside 10.10.10.0 255.255.255.0 xxx.xxx.xxx.xxx 254

    (value of 254 is a more expensive route to go via IPSec tunnel and x = the bridge by default-ISP)
