LAN-to-lan ipsec vpn

Hi all

I need to change my actual lan-to-LAN vpn configuration in host-to-lan, and I have a few questions. Maybe someone here can help me.

Current configuration:

SITE A:

-cisco 892

-subnet: 192.168.1.0/24

SITE B:

-hub cisco 3000

-subnet 192.168.2.0/24

I have access to only the site router.

Currently, all clients in the site one can reached site B and vice versa.

Here are my ACLs of the SITE a router:

ip permit 192.168.1.0 0.0.0.255 192.168.2.0 0.0.0.255

Now, I need to change the vpn config in:

-vpn ipsec must be configured between 192.168.2.0/24 (SITE B) and 10.1.1.1/32 (ip protocol used for the nat all clients from SITE A to SITE B)

SITE A router ACL shoul become:

permit host 10.1.1.1 ip 192.168.2.0 0.0.0.255.

All SITE A clients who want to join the SITE B are nat - ed by 10.1.1.1. SITE B cannot reach subnet A SITE, only 10.1.1.1

Now the questions:

IP address 10.1.1.1 shoul be configured on a loopback interface?

How the nat configuration?

Thank you very much.

Hello Richard,.

10.1.1.1 will be configured on loopback interaface. Here's the basic config->

interface Loopback0

10.1.1.1 IP address 255.255.255.255

NAT outside IP

interface FastEthernet0/0

IP 192.168.1.1 255.255.255.0

IP nat inside

interface FastEthernet0/1

IP 23.0.0.2 255.255.255.0

NAT outside IP

card crypto WCPA

overload of IP nat inside source list VPN_NAT_ACL interface Loopback0

VPN_NAT_ACL extended IP access list

ip permit 192.168.1.0 0.0.0.255 192.168.2.0 0.0.0.255

VPN_TRAFFIC_ENCRYPT extended IP access list

permit host 10.1.1.1 ip 192.168.2.0 0.0.0.255

LAN-to-LAN IPsec VPN with overlapping networks problem

I am trying to connect to two networks operlapping via IPsec. I already have google and read

http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml

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 (like 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 (mainly 10.100.x.0/24). I have not implemented this ASA, we took over this infrastructure without other documentation whatsoever.

According to the above link I should use double NAT. Site_B will see the Site_A as 10.26.0.0/22 networks, and Site_A see networks in Site_B as 10.25.0.0/24. Site_A is allowed access only 10.100.1.0/24 in the Site_B, and Site_B is allowed access to all the networks of the Site_A 10.100.x.0/24 - so / 22 10.26.0.0/22 mask. I would like, for example, ssh to host in the Site_B to host the Site_A using 10.26.1.222 as the destination ip address (and it should be translated in 10.100.1.222 on the side Site_A). I'm looking for something like ip nat type match-host in Cisco routers - I want to translate only a part of the network address leave the intact host Party. Anyway, following the steps from the link displayed above everything is ok until the command:

static (companyname, outside) 10.26.0.0 access list fake_nat_outbound

which translates into:

WARNING: address real conflict with existing static

TCP companyname:10.100.0.6/443 to outside:x.x.x.178/443 netmask 255.255.255.255

TCP companyname:10.100.0.28/3389 to outside:x.x.x.178/2003 netmask 255.255.255.255

Those are redirects to port on Site_A used for mail, webmail, etc. What should I do to keep the redirects from the Internet to companyname vlan and at the same time to have work l2l ipsec tunnel linking networks that overlap?

Thank you in advance for any help or advice.

Are you sure that static-config does not make to the running configuration?

By applying this 'static big' you're essentially trying to redirect the ports, which have already been transmitted by the rules in your existing configuration. This explains the caveat: what you are trying to do has some overlap with existing static.

(Sorry for the use of the transmission of the word, but this behavior makes more sense if you look at it like this; although "port forwarding" is not Cisco-terminology.)

But... whenever I stumbled upon this question, the warning was exactly that: a WARNING, not an ERROR. And everything works as I want it to work: the specific static in my current config simply have priority over static grand.

If you would like to try to do the other opposite you would get an error (first static major, then try to apply more specific) and the config is not applied.

So could you tell me the config is really not accepted?

Using to relay DHCP on LAN remote IPSec VPN WRVS4400N

Hello

I have a WRVS4400N. I want to know if it is possible to configure the remote relay DHCP WRVS4400N to find a DHCP server on the local network. The local network is 192.168.2.0/24, and the Remote LAN is 192.168.1.0/24. I am entered the field of relay DHCP server 192.168.1.100 but my local PC does not get an IP address. So, I would like to than the local PC to get an IP from DHCP address 192.168.2.x server remote (LAN) through the IPSec VPN tunnel. Is this possible?

The IPSec tunnel works. I ping the 192.168.1.100 remote DHCP server, if the local PC, a static IP address 192.168.2.x I have the configuration of the DHCP server with an IP of 192.168.2.x/24 range.

The remote VPN router is a Netgear FVS114.

Thank you

NIC

The wrvs4400n, you cannot do the dhcp relay in the vpn tunnel. You may need to get a business for which solution or a connection point to point for both networks on the same local network configuration.

I'm sure it has something to do with NAT or an access list, but I can't understand it at all. I know it's a basic question, but I would really appreaciate help!

Thank you very much

Trevor

"No. - nat' ACL doesn't seem correct, please make sure you want to remove the following text:

do not allow any No. - nat icmp access list a whole

No No. - nat ip 172.16.0.0 access list allow 255.255.0.0 any

No No. - nat access list permit icmp any any echo response

No No. - nat access list permit icmp any any source-quench

No No. - nat access list permit all all unreachable icmp

No No. - nat access list do not allow icmp all once exceed

No No. - nat access list only allowed icmp no echo

You must have 1 line as follows:

access-list no. - nat ip 192.168.5.0 allow 255.255.255.0 172.16.0.0 255.255.0.0

Please 'clear xlate' after the changes described above.

In addition, if you have a personal firewall enabled on the host you are trying to connect from the Client VPN, please turn it off and try again. Personal firewall of Windows normally blocks the traffic of different subnets.

Hope that helps.

Customer remote cannot access the server LAN via VPN

Hi friends,

I'm a new palyer in ASA.

My business is small. We need to the LAN via VPN remote client access server.

I have an ASA5510 with version 7.0. I have configured remote access VPN and it can establish the tunnel with success. But I can not access the server.

Client VPN is 5.0.07.0290 version. Encrypted packages have increased but the decrypted packet is 0 in the VPN client statistics, after I connected successfully.

Next to the ASA, I show crypto ipsec sa, just deciphering the packets increase.

Who can help me?

Thank you very much.

Unable to access company LAN via VPN

Hello

I have an ASA 5505 that I used to test run them the IPSec VPN connection after having studied the different configs and crossing the ASDM I get the same question that I can not receive any traffic.

The company LAN is on a 10.8.0.0 255.255.0.0 network, I placed the VPN clients in 192.168.10.0 255.255.255.0 network, 192 clients may not speak on the 10.8 network.

On the Cisco VPN client, I see a lot of packets sent but no receipt.

I think it could be to do with NAT, but the examples I've seen I think it should work.

I have attached the complete running-config, I might well have missed something.

Thanks a lot for all the help on this...

As you can see, I have create a new pool, since you already have an interface in the 192.168.10.0/24 network, which affects VPN clients.

Once you have finished, connect the client and try:

Ping 10.8.127.200

It work?

Try to ping so another internal IP.

Let me know how it goes.

WRV200 ipsec VPN

Hi guys,.

Tried to set up an ipsec VPN LAN - LAN between my WRV200 and WRVS4400N my companion. Filled all the relevant config... simple... but still nothing. They don't seem to connect. We are both on ADSL and using IP address by DNS. Routers are in the log file and try to establish the connection. Tried all the setting, both routers are configured the same. STILL NO JOY! Can anyone help, before having to migrate to a netgear or something nasty!

Sorry forgot to mention, using an AM200 modem in Bridge mode. It my router DHCP address direct WAN instead of NAT. The two systems are fixed the same where routers have outside the WAN address. The modem is transparent. I guess that NAT traversal in not required in that State.

Router Cisco 1941 - crypto isakmp policy command missing - IPSEC VPN

Hi all

I was looking around and I can't find the command 'crypto isakmp policy' on this router Cisco 1941. I wanted to just a regular Lan IPSEC to surprise and Lan installation tunnel, the command isn't here. Have I not IOS bad? I thought that a picture of K9 would do the trick.

Any suggestions are appreciated

That's what I get:

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:

Microsoft l2tp IPSec VPN site to site ASA on top

I have a specialized applications casino that requires end-to-end encryption. I'm under the stack of Microsoft IPSec l2tp between my XP machine and my Windows 2003 server on the LAN. Can I use the same type of protocol stack Microsoft l2tp IPSec between my XP machine and the Windows Server 2003 a branch on the SAA to site to site ASA VPN tunnel? The VPN site-to site ASA is a type of key Preshare IPSec VPN tunnelle traffic between our head office and a branch in distance.

In other words, the ASA site-to-site IPSec VPN will allow Microsoft l2tp through IPSec encrypted traffic? My ACL tunnel would allow full IP access between site. Something like:

name 192.168.100.0 TexasSubnet

name 192.168.200.0 RenoSubnet

IP TexasSubnet 255.255.255.0 RenoSubnet 255.255.255.0 allow Access-list extended nat_zero

Hello

Yes, the L2TP can be encapsulated in IPSEC as all other traffic.

However, make sure that no NAT is performed on each end. L2TP is a default header protection which will see NAT as a falsification of package and reject it.

See you soon,.

Hello guys,.

I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

The question statement not the interface pointing to ISP isn't IP address private and inside as well.

Firewall configuration:

Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

I have public IP block 199.9.9.1/28

How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

Please help with configuration examples and advise.

Thank you

Eric

Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

3 options:

(1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

OR /.

(2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

OR /.

(3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

Internet through a RA IPSec VPN Tunnel traffic

Armed with an ASA 5505 Security Plus, I configure IPSec VPN for RA the VPN IP address pool is in the 192.168.2.0/28 network.

The Lan is 192.168.1.0/24 with inside interface a.254.

The VPN works great. What I would do is to route all internet through the firewall traffic when users are connected to the VPN. I put this gateway 192.168.1.254 tunnel, but I'm having no luck to get it works.

Any ideas?

Thanks in advance!

You are just going to route internet traffic to the remote vpn client to the ASA and backward on the Internet?

If the above statement is correct, you need not configure the tunnel default gateway.

But you need to configure NAT for the ip pool, so they can go to the internet, as well as the 'same-security-movement' command as follows:

NAT (outside) 1 192.168.2.0 255.255.255.0

permit same-security-traffic intra-interface

In addition, assuming that you have not have split configured tunnel.

I only give your router cisco 892 because there is nothnig much to change on linksys wrv210 router.

Hope someone can help me. See you soon

You can run a "ip inspect log drop-pkt" and see if get you any what FW-DROP session corresponding to the traffic you send Linksys to the main site. Zone based firewall could be blocking traffic initiated from outside to inside.

Problems with remote access IPSec VPN

Dear Experts,

Kindly help me with this problem of access VPN remotely.

I have configured remote access VPN IPSec using the wizard. The remote client connects to fine enough seat, gets the defined IP address, sends the packets and bytes, BUT do not receive all the bytes or decrypt packets. On the contrary, the meter to guard discarded rising.

What could be possibly responsible or what another configuration to do on the SAA for the connection to be fully functional?

It can help to say that Anyconnect VPN is configured on the same external Interface on the ASA, and it is still functional. What is the reason?

AnyConnect VPN is used by staff for remote access.

Kindly help.

Thank you.

Hello

So if I understand correctly, you have such an interface for LAN and WAN and, naturally, the destination networks you want to reach via the VPN Client connection are all located behind the LAN interface.

In this case the NAT0 configuration with your software most recent could look like this

object-group, LAN-NETWORKS-VPN network

network-object

network-object

network-object

network of the VPN-POOL object

subnet

destination of LAN-NETWORKS-VPN VPN-NETWORKS-LAN static NAT (LAN, WAN) 1 static source VPN-VPN-POOL

Naturally, the naming of interfaces and objects might be different. In this case its just meant to illustrate the purpose of the object or interface.

Naturally I'm not sure if the NAT0 configuration is the problem if I can't really say anything for some that I can't see the configuration.

As for the other question,

I have not implemented an ASA to use 2 interfaces so WAN in production environments in the case usually has separate platforms for both or we may be hosting / providing service for them.

I imagine that there are ways to do it, but the main problem is the routing. Essentially, we know that the VPN Client connections can come from virtually any public source IP address, and in this case we would need to default route pointing to the VPN interface since its not really convenient to set up separate routes for the IP address where the VPN Client connections would come from.

So if we consider that it should be the default route on the WEBSITE of the ASA link, we run to the problem that we can not have 2 default routes on the same active device at the same time.

Naturally, with the level of your software, you would be able to use the NAT to get the result you wanted.

In short, the requirements would be the following
- VPN interface has a default route, INTERNET interface has a default route to value at the address below
- NAT0 between LAN and VPN interface configuration to make sure that this traffic is passed between these interface without NAT
- Interfaces to special NAT configuration between LAN and INTERNET which would essentially transfer all traffic on the INTERNET interface (except for VPN traffic that we have handled in the previous step)
The above things would essentially allow the VPN interface have the default route that would mean that no matter what the VPN Client source IP address it should be able to communicate with the ASA.

The NAT0 configuration application would be to force ASA to pass this traffic between the LAN and VPN (pools) for VPN traffic.

The special configuration of NAT then match the traffic from LAN to ANY destination address and send to the INTERNET interface. Once this decision is made the traffic would follow the lower value default route on this interface.

I would say that this isn't really the ideal situation and the configuration to use in an environment of productin. It potentially creates a complex NAT configuration such that you use to manipulate the traffic instead of leave the mark of table routing choice in the first place.

Of course, there could be other options, but I have to test this configuration before I can say anything more for some.

Peer IP: 111.111.111.111

Local network: 10.0.0.0

Branch

Peer IP: 123.123.123.123
