We are using a CISCO1921-SEC Router. On the "WAN" side we have 1 public IP Adress assigned by DHCP. At the moment we are using the WAN Interface with a crypto-map as endpoint of some IPSec connections. We set up a zone-based-firewall with "WAN" and "LAN" zone. In this setup all IPSec Endpoints are on one Interface - connections to the "LAN" zone can be managed by rulesets. What about connections between IPSec connections and the zone "self".We like to terminate each IPSec connection in a separated zone. How can this be configured ?Each one on a "tunnel inetface" with "tunnel source ..." binding ?
On our ASA 5510 we already have one ISP link terminated on outside interface. There is correspoinding nat and global configured for outbound access to internet.
Now we need to terminate second ISP link on one of the DMZ interface to have redundancy for the primary ISP.
When primary ISP link or router is down we need to send all the traffic to secondary ISP router. How do we configure NAT and global for this condition that only when primary is down then only this NAT -Global should be used. Do we have anything like object tracking associated with the NAT-global.
So that as long as Primary RTR - object is up ASA will use the first NAT-Global pair. When primary ISP is down RTR-Object is not reachable then ASA will perform the second NAT-Global operation.
Also can we have default route pointing to Outside interface (primary ISP router) and in case of primary router failure it will point to secondary ISP. Do we have "track" in the static route commands on ASA.
I have a 5510 with me. I want to terminate two Internet links on that. The primary Internet Leased Line to access my DC network using Site-to-Site VPN, and the secondary ADSL connection to access my other location network via VPN and and for web browsing. How can I achieve these goals.
I have a customer that wants to purchase an ASA 5510 security plus to terminate client VPN access for an external support team. The customer claims to want URL content filtering/proxy which leads me to suggest a CSC SSM 20 plus module. But upon further conversation, he mentioned wanting IPS. In this case, the customer does not seem to know the difference between the URL content filter/proxy and the IPS and uses both terms interchangably.
1. What would you suggest in your expert opinion would be the best module to get for this customer? IPS or CSC
2. If I go with the CSC module, where can I find good documentation on how to configure it and get it up to date?
3. does the CSC module provide any web proxy functionality?
I would like to know if there is any command that i can use to terminate a site-to-site connection and restart it whenever i want to.I don't want to use the shut down command since i use the specific interface as an exit point to the internet.
We're in the process of setting up an ASA 5510 as our main VPN appliance.
The Outside interface of the 5510 faces our DMZ, the Inside interface sits on our main network. The 5510 uses radius for authentication going to a server on the same subnet for the authentication. That works fine. VPN client can connect to the 5510 and successfully authenticate. Routes are pass through to the VPN client, no problem. PC with VPN client can access internet (which is by design, it should use it's own internet connection), but cannot ping/access/trace over the tunnel at all.
My hunch is that this is a nat issue - but I am confused as to how the NAT should be configured - I've tried several configurations with no luck.
The VPN client is set to pull an ip address from the pool - 192.168.56.10 - 100. The 5510 is sitting on a separate subnet (50.x/22). This seems to work on the Cisco 1700 that it will be replacing just fine. I mirrored routes and ACLs as well onto the new 5510. No luck. Client connects, authenticates, pulls an IP address and routes, but can't see anything on the inside of the 5510.
I have an ASA 5510 running 8.4(2) which has a site to site IPSec VPN to a 3rd party who run some form of Checkpoint. The VPN establishes and allows access to a server in our DMZ on all ports that we have tested (so far HTTP, SSL, RDP, FTP) except for SQL which doesn't even seem to reach the server. I've got Wireshark running on the DMZ server and if the 3rd party initiates a TCP conversation from their server on any of the working ports to the server I see all of the expected packets arrive with the correct IPs etc (no NAT takes place across the VPN) but when an ODBC client attempts to query the SQL server on our DMZ box the packets do not arrive at the server. What I can see is the RX byte count on the VPN increasing each time the query is run but definitely no SQL arriving at the server.
Also if I revert the ASA back to the old PIX it has replaced with the same VPN config but on version 7.x then it works just fine.
I have been given the following details by a company for us to connec to their IPsec VPN.
IP Address 18.104.22.168 VPN Device Description Cisco ASA VPN Device Version 5510 Encryption Domain 10.152.24.10 Authentication Method Pre Shared Key Encryption Scheme IKE
I was going to use VPNC with linux but the company said they do not use remote access. So I tried a draytek vigor 3300v, that as well did not work. Had very bad logging so i couldn't troubleshoot.In the end I have decided to buy the cheapest cisco device that will allow me to connect to this.
I have an ASA 5510 running ver 8.0(2) that has (4) Ipsec tunnels going from it to various other locations. I am having an issue with data transfer speed on only one of the Tunnels. This tunnel is between the 5510 and the 5555, on that link I am getting a dat transfer rate of a little over 120k a second, whereas if I pull the same set of files from another location I am seeing a transfer rate of 5m per second.
I have verified that it is not a capacity issue on the Internet bandwidth on both locations, and I can pull the same data from the same location to various other locations via Ipsec tunnels, I am only having an issue with a specific tunnel going from the 5510 to the 5555.
Since it is not affecting other tunnels on the 5510 nor is it affecting tunnels on the 5555 going to other locations, I am leaning toward a routing issue within the ISP? I will say the ISP is taking me a long way around to stay in the same Metropolitan area.
i've an Cisco ASA 5510 with Security Appliance Software Version 8.0(2), in this ASA i've many L2L tunnels to this ASA, anda sometims new tunnels can't connect, the older tunnels still ok and working, yesterday this situation occured again and i've tried to clear all ipsec tunnels and try to reconnect again no one cames up again. At the time of this situation memory usage was about 78% and CPU is was around 5%. I've made a reload without changes and the situation returns to the normality.
At the time of the fail i've collect the outpu from debug crypto isakmp 255, the outpu was in the annexed file.
We have built IPSEC VPN over MPLS P2P circuit between Head & Branch office using Cisco ASA 5510. Client systems at Branch office connects to Citrix app at Head office, but it gets disconnect intermittently for all user. if any recommendations/changes required for Citrix App whn passing over IPSEC VPN/ ASA.
I have a 5510 that i have configured for L2TP over IPSEC, not using AnyConnect. The first, and most prevelant being, VPN clients are unable to ping/access any of the hosts that are assigned a static NAT from the inside interface to the outside interface. I was able to circumvent this by adding another static NAT to the public interface for the incoming clients, but this caused intermittent connectivity issues with inside hosts. The second issue involves DNS. I have configured two DNS servers, both of which reside on the internal network and are in the split_tunnel ACL for VPN clients, but no clients are using this DNS. What is the workaround for using split tunneling AND internal DNS servers, if any?
i've had two different CCNA's look at this numerous times to no avail. A ping from a VPN client to any internal host works fine, unless it is one that is NAT'd. You can see in the config where i added the extra STATIC NAT to try and fix the issue. And this works perfectly across the tunnel but only intermittenly from the internal 10.1.4.x network. [code]
I have a 2811 that is my HQ router with a 10MB pipe. I was trying to configure a IPSEC tunnel to connect to my ASA that has access to our companies internal servers on the 10.33. and 172.16.31 network. I am having a problem getting phase 1 to even come up. I've looked over the configurations and unless i'm overlooking something I dont see what could be keeping it from at least completing phase 1
Below are the configs. 2811-CFG crypto isakmp policy 10 encr 3des hash md5 [Code] ....
I currently have an ASA 5510 setup with Dual homed ISP's and a remote access IPsec VPN setup to terminate at either interface. The first interface is named Outside and the second is simply called Outside-2. When outside the company(such as at home), the VPN client will connect on the Outside-2 interface and work normally. The problem is while testing on our DMZ, the VPN Client will not connect on the Outside-2 interface. It will try that interface fail to connect and then connect to the backup Outside interface. This isn't a huge concern because it still connects, but if we were ever to get rid of one of those connections, it would be nice to reliably test from our DMZ.
I am trying to pass Traffic thru the IPSEC tunnel but it does not work ([Cisco Router 892] <---> [Cisco ASA 5510] <---> [Cisco Router 892]) The Cisco ASA 5510 doesn't pass traffic UDP=500 & UDP=4500 ports...
Attached are the configuration files for the devices in question. I have a 5510 that belongs to my company and a 5505 that belongs to another company. The 5505 sits behind the 5510 and is able to connect to the Internet. My thought was that VPN access should be a trivial pursuit. I was planning on just giving the admin at the remote office the public IP address that's natted to the 5505 and all would be good.
WRVS4400N Version V22.214.171.124.I have been attempting for weeks to connect an IPSEC tunnel between a Cisco ASA 5510 Version 8.0(2) and a WRVS4400N . Phase one seems connect okay, where as phase two always give me the errors below. This as far as I have got, I tried disabling keep alive monitor, the device never attempted phase 2. I have read endless documentation on both devices and tried almost every combination of setting that I am aware of. The best case scenario answer would be detailed steps on how to setup the IPSEC VPN (linksys) & the site to site VPN (CISCO) as I cannot find any reference material for this combination .
Co-worker just got a Blackberry Playbook tablet and, try as I might, we cannot get the darn thing to successfully set up a working IPSEC/L2TP vpn tunnel to our ASA 5510, which acts as a multi-purpose VPN concentrator. Any luck setting up L2TP/IPSEC VPN to ASA from Blackberry Playbook?
I'm trying to connect two operlapping networks via IPsec.
Details:Site_A use ASA 5510 with software version 8.0(4)32. Site_A use 10.100.0.0/24, 10.100.1.0/24 and 10.100.2.0/24 inside networks. 10.100.0.0/24 is directly connected to ASA (as vlan10), 10.100.1.0/24 and 10.100.2.0/24 are routed.Site_B use Linux box and networks 10.100.1.0/24, 10.100.2.0/24, 10.100.3.0/24 and so on (basically 10.100.x.0/24). I didn't set up this ASA, we took over this infrastructure without any documentation whatsoever.
According to link posted above I should use dual NAT. Site_B will see networks in Site_A as 10.26.0.0/22, and Site_A will see networks in Site_B as 10.25.0.0/24. Site_A is allowed to access only 10.100.1.0/24 in Site_B, and Site_B is allowed to access all 10.100.x.0/24 networks in Site_A - hence /22 mask in 10.26.0.0/22. I'd like to, for example, ssh from host in Site_B to host in Site_A using 10.26.1.222 as destination ip address (and it should be translated to 10.100.1.222 on the Site_A side). I'm looking for something like ip nat type match-host in Cisco routers - I want to translate only network part of the address an leave the host part intact. Anyway, following the steps from the link posted above everything is ok till the command:
I'm attempting to debug an ipsec tunnel on an ASA 5510 (8.4(3)) and when I turn on `debug crypto ipsec` and then execute `logging monitor` I get an constant stream of TCP debugging events, is it possible to only view ipsec messages?
I have created an IPSec VPN between our ASA (5510) and a Cisco Router running IOS.Only problem i have is that the VPN goes down if there's no interesting traffic from the router and i can't find anything to initiate the VPN Tunnel from the ASA (so we need to wait 'till someone connects on the other side).
Is there any way to make this connection persistent, just like an ASA-to-ASA tunnel?
I'm opening a new topic related to my problem with the VPN connection, to avoid confusion, since there are many, in the old information, no longer required.
I would like to configure my ASA5510 L2PT/IpSec to accept connections from Windows clients. I happen to authenticate via AD credentials. When I try to connect is because the error 691. I enabled debugging on the machine the following:
I have a 5510 and a 5505 that I'm attempting to configure a simple VPN tunnel over. I have tried step by step configurations form CISCO ASA configs, as well as every source I can find. I have walked throught the config with IOS commands as well as Wizards. All my packets are dropped at the the inside or outside interface.
When I show SH ISAKMP command all I get are 0's straight down.
we have a local Netflow collector working fine. We also have a centralised collector that we’d like to use to send the same Netflow data, but it is not being received. We need to send the data via an IPSEC VPN.
When I do a 'show flow-export counters' I can see the packets sent increasing. The local collector is receive netflow data. I am using the below config,
access-list global_mpc extended permit ip any any ! !IP far end of VPN
we have a Cisco ASA 5510 8.4, this device is reachable through a lan to lan IPsec vpn. We are able to activate the netflow export (we see flow export counters incrementing), but the flow is not passing through the vpn. Our netflow collector is on the other side of the IPsec tunnel so we define it linked to the internet interface.Is the export possible through the vpn? I read in a Solarwinds forum that it should not be possible.What ip address is choosen as source interface by ASA? Is there a way to force a source interface?
i configurated ipsec vpn at cisco asa 5510. all them are working very well. now i want to change ipsec remote vpn to L2tp over ipsec.i have router, asa and 3750 switch. all nat translation are done at router , ipsec vpn configurate at asa.
this is my ipsec configuration. this is working config. as you see i do static nat asa outside ip for vpn at router. now i want l2tp over ipsec. before i do it i have some question
1. must i do static nat port udp 1701 for l2tp over ipsec vpn? can i write access list at asa to open port 1701?
2. can i remove this static nat or i can not be change anything.is this nat is true for l2tp over ipsec vpn?
3.as you see user authentication from radius server at ipsec vpn. i also want this is same as l2tp over ipsec vpn..
4. i think that i must be add this addtional config. is this true? tunnel-group DefaultRAGroup ppp-attributesno authentication chapauthentication ms-chap-v2
is this config enougth for l2tp over ipsec vpn?? what is addtional config i need?
