VPN site to site - IPSEC TUNNEL
I have 2 servers that communicate with each other, using a middleware which has no NAT support.
This middleware, named RTI DDS uses multicast packets.
I need to place the 2 servers in 2 different cities.
On each location, I have a router connected to the other end with a dedicated line.
The version of the IOS on the cisco routers is ADVANCED (the one with the cryptographic features)
The middleware using NAT (which cache servers IP address) cannot work.
A VPN between my two sites can solve my problems of communication?
If so, I'll show what I did (maybe I did something wrong in the creation of VPN).
Because I am tring to create a VPN with an IPSEC TUNNEL
Thank you.

The first several times I have lived these configs I was concentrating on the ISAKMP and IPSec - aspects and did not find a problem with them. Then after you posted my answer I went through the congfigs once again, and I think I see the problem. There is no routing information in the configs. If Site_Router does not know where 172.27.1.0/24. When the server on its local network attempts to ping the server else she has no way to transfer the package. And the same CO_Router don't know how to get to 172.27.2.0.
If solve you the problem with the routing information, I think that the ISAKMP negotiation can work.

remote users access site ipsec tunnel
How to configure the ACL and the road to allow remote users access to site ipsec as local users?
Current scenario is
1. distance users (192.168.2.0/24) ipsec <->Cisco 870 (192.168.0.0/24)
(2 cisco 870(192.168.0.0/24) ipsec tunnel <->cisco 1811 (10.0.0.0/24)
Now remote users can access the 192.168.0.0 network, no problem, but how they can access 10.0.0.0 network?
I guess I can do like this:
1. in cisco 870, site to site ip 192.168.0.0 tunnel allow 0.0.0.255 10.0.0.0 0.0.0.255
(add) permit ip 192.168.2.0 0.0.0.255 10.0.0.0 0.0.0.255
2. in the site-to-site vpn cisco 1811
(add) permit ip 10.0.0.0 0.0.0.255 192.168.2.0 0.0.0.255
3. in settings vpn split cisco870 add the 10.0.0.0/24 network
Is this fair?
Thank you.
You must configure the interesting traffic that an ACL contains the source is remote destination as local LAN and LAN.

Site to Site IPSEC tunnel (5505 at 5505) blocking certain ports?
I have problems with the traffic between two connected 5505 at 5505 sites (lan to lan) ipsec tunnel. feature of 99% of the traffic on the tunnel seems good with one exception. When a pc on Site A tries to access a mangagment base tool (java embedded) web for an IP_PBX to the site B, part of the traffic does not result in an odd error. The client pc can ping and hit port 80 to prompt the web GUI, gets invited to download java and load the java web application embedded. The java application itself (a terminal CLI to replicate if you were just Telnet to) gives an error as it cannot successfully connect to the IP_PBX. We have other sites where the ipsec tunnel is between two 2800's, and there is NO problem. The provider IP_PBX suggest that we open port 2000. Personally I'm not familiar with the ASA to uderstand why he would block only certain ports on an ipsec tunnel. I'm particularly confused because there is no NAT'ing involved in trafficking through this tunnel ipsec 5505 to 5505.
Any suggestions would be greatly appreciated,
BH
I can post configs if necessary, but thought someone might be already familiar with this issue.
Thanks again.
Ok.
What is stable with the ACL I mentioned:
test2000 list access permitted tcp/udp any host x.x.x.x eq 2000
test2000 ip access list allow a whole
Access-group interface inside test2000
The idea is to check if the ASA transfers traffic x.x.x.x on port 2000 coming out to the inside network.
If you see hitcounts on the first statement, the ASA transfers the packets and the problem is maybe with the server itelf or return circulation.

VPN site-to-site does not not between PIX515e and ASA5505
Hello
I was hoping that someone could help me to get this vpn to work. IPSec tunnels are not and I noticed the error:
3 August 9, 2011 05:13:26 IP = 39.188.41.188, error during load processing: payload ID: 1 Read on this it seems that this could be a problem of IKE, but I am struggling to find the cause (not helped by the News 8.4 orders).
The configuration is as follows: -.
Head office
PIX515e v6.3 (4)
IP LAN 10.0.160.254/24
Branch
ASA5505 v8.4 (1)
IP LAN 192.168.47.254/24
I have attached the configs - can someone help me with this?
See you soon,.
Huw
Huw,
1. you do not have an ISAKMP policy that corresponds to the remote site (BTW, you do not have a lot of policies of serving, you may want to consider cleaning your config before adding a new policy)
HQ you have this:
part of pre authentication ISAKMP policy 20
ISAKMP policy 20 3des encryption
ISAKMP policy 20 md5 hash
20 2 ISAKMP policy group
ISAKMP duration strategy of life 20 86400
You need this on remote sites:
IKEv1 crypto policy xx
preshared authentication
3des encryption
md5 hash
Group 2
life 86400
2. your interesting traffic is not appropriate:
At the remote sites, you must
the DM_INLINE_NETWORK_1 object-group network
object-network 10.0.160.0 255.255.255.0
object-network 192.168.1.0 255.255.255.0
access extensive list ip 192.168.47.0 outside_cryptomap allow 255.255.255.0 DM_INLINE_NETWORK_1 object-group
On the AC:
name 10.0.160.0 ENO_LAN
name 192.168.47.0 EASTMOORS_LAN
outside_cryptomap_20 ENO_LAN 255.255.255.0 ip access list allow EASTMOORS_LAN 255.255.255.0
Need to add this:
inside_outbound_nat0_acl ENO_DMZ 255.255.255.0 ip access list allow EASTMOORS_LAN 255.255.255.0
Once you have applied these changes try to ping through the tunnel. If this still does not please take a show crypto isa's and see the crypto ipsec its on both sites.
Thank you.

ASA ASA from Site to Site VPN IPSec Tunnel
Any help would be greatly appreciated...
I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.
Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24
Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24
Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.
Internet access works very well in all workstations of this site. A static route is configured to redirect all traffic to a public router upstream.
Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address. A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA. A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253. This device then performs its own private Public NAT. Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)
The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24). The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254). The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem. However, all traffic passing on networks ICMP does not end and the Syslog reports the following-
Site #1-
6 January 19, 2011 15:27:21 302020 ZEFF-SB-01_LAN 1 10.1.1.51 0 Built of outbound ICMP connection for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1 6 January 19, 2011 15:27:23 302021 10.1.1.51 0 ZEFF-SB-01_LAN 1 Connection of ICMP disassembly for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1 Site #2-
6 January 19, 2011 15:24:47 302020 10.1.1.51 0 10.0.0.30 1 Built of outbound ICMP connection for faddr gaddr laddr 10.1.1.51/0 10.1.1.51/0 10.0.0.30/1 6 January 19, 2011 15:24:49 302021 10.0.0.30 1 10.1.1.51 0 Connection of disassembly for faddr gaddr laddr 10.1.1.51/0 10.1.1.51/0 10.0.0.30/1 ICMP It's the same for any form of traffic passing over the tunnel. The ACL is configured to allow segments of LAN out to any destination. At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).
Anyone can shed light on a possible cause of this problem?
Thank you
Nick
did you bypass the vpn traffic between 10.0.0 and 10.1.1 to be NAT - ed on the two ASA?
Please provide the following information
-set up the tunnel
-show the isa cry his
-show the ipsec cry his
-ping of the site 1 site 2 via tunnel
-capture "crypto ipsec to show his" once again
-ping from site 2 to 1 by the tunnel of the site
-capture "crypto ipsec to show his" once again
-two ASA configuration.

I tried ISA550 a config with the same constelations, but without suggesting.
Anyone has the same problem?
And had anyone has a tip for me, or has someone expirense with a site-by-site with ISA550 and Cisco 2821 ipsec tunnel?
I can successfully establish a tunnel between openswan linux server and the isa550.
Patrick,
as you can see on newspapers, the software behind ISA is also OpenSWAN
I have a facility with a 892 SRI running which should be the same as your 29erxx.
Use your IOS Config dynmap, penny, you are on the average nomad. If you don't have any RW customer you shoul go on IOS "No.-xauth" after the isakmp encryption key.
Here is my setup, with roardwarrior AND 2, site 2 site.

IPSec VPN Site-to-Site router Cisco 837 to Firewall FortiGate 200 has
I had a challege for a site to site vpn scenario that may need some brainstorming you guys.
So far, I have had a prior configuration planned for this scenario, but I'm not very sure if the tunnel I created will work because I did not test it before with this scenario. I'll go next week on this project and hopefully get a solution of brainstorming you guys. Thanks in advance!

Hello
Three changes required in this configuration.
(1) change the NAT-list access 102 as below:
access-list 102 deny ip 10.20.20.0 0.0.0.255 172.20.10.0 0.0.0.255
access-list 102 permit ip 10.20.20.0 0.0.0.255 any
(2) place the card encryption on interface point-to-point ATM.
(3) remote all of a default route.
Thank you

Tunnel VPN site to Site with 2 routers Cisco 1921
Hi all
So OK, I'm stumped. I create much s2s vpn tunnels before, but this one I just can't go there. It's just a tunnel VPN Site to Site simple using pre-shared keys. I would appreciate it if someone could take a look at our configs for both routers running and provide a comment. This is the configuration for both routers running. Thank you!

When the GRE tunnel carries your traffic to private ip range, your ACL must contain address of the host of point to point the IPSec tunnel.
Since then, both routers are running EIGRP in the corporate network, let the EIGRP Exchange routes via GRE tunnel, which is a good practice, rather than push the ip ranges private individual through the IPSec tunnel.
Let me know, if that's what you want.
Thank you

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,.

Static - VPN Site to Site DMVPN Tunnel
Hello
I have two sites, Site-a with Cisco ASA 5505 static IP Configuration & Site-B 1841 Cisco ISR with dynamic IP Configuration.
See the diagram attached for a glimpse.
The goal is to have the tunnel VPN Site to Site between the site of two so that desktop sitting in Site B can access the server applications residing in the Site-A.
Please suggest
Concerning
@Mohammed
Hello
A site to Site IPSec, the ASA is the static side and he should have the 'dynamic' configuration, and the side Dynamics SRI 1841 should have the static side:
I'll give an example configuration to achieve, but you can use a different encryption algorithms:
ASA 5505:
Phase 1:
crypto ISAKMP policy 1
3des encryption
md5 hash
preshared authentication

Hey all, I was instructed to set up a tunnel vpn site-to-site between 2 offices. I think I have everything configured correctly for the most part, but when I generate a valuable traffic, tunnel does. Can you tell me to look at the debug output below what could be the problem? Aaa.aaa.aaa.aaa my IP address and the IP address of my counterpart is bbb.bbb.bbb.bbb

Routing of traffic between two VPN Site-to-Site Tunnels
Hi people,
I am trying to establish routing between two vpn Site-to-Site tunnels which are destined for the same outside the interface of my Cisco ASA.
Please find attached flowchart for the same thing. All used firewalls are Cisco ASA 5520.
Two VPN tunnels between Point A and Point B, Point B and Point C is too much upward. I activated same command to permit security level interface also intra.
How can I activate the LAN subnets traffic behind Point to join LAN subnets behind C Point without having to create a tunnel separated between Point A and Point C
Thank you very much.
Hello
Basically, you will need to NAT0 and VPN rules on each site to allow this traffic.
I think that the configurations should look something like below. Naturally you will already probably a NAT0 configuration and certainly the L2L VPN configuration
Site has
access-list NAT0 note NAT0 rule for SiteA SiteC traffic
access-list allowed NAT0 ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
NAT (inside) 0 access-list NAT0
Note L2L-VPN-CRYPTO-SITEB access-list interesting traffic for SiteA to SiteC
access-list L2L-VPN-CRYPTO-SITEB permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
Where
- NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteA SiteC NAT traffic
- NAT = is the line of configuration NAT0
- L2l-VPN-CRYPTO-SITEB = LCA in configurations VPN L2L that defines the SiteA LAN to LAN SiteC traffic must use the VPN L2L existing SiteB
Site B
access list OUTSIDE-NAT0 note NAT0 rule for SiteA SiteC traffic
OUTSIDE-NAT0 allowed 192.168.1.0 ip access list 255.255.255.0 192.168.3.0 255.255.255.0
NAT (outside) 0-list of access OUTSIDE-NAT0
Note L2L-VPN-CRYPTO-SITEA access-list traffic for SiteA to SiteC through a Tunnel between A - B
access-list L2L-VPN-CRYPTO-SITEA ip 192.168.3.0 allow 255.255.255.0 192.168.1.0 255.255.255.0
Note L2L-VPN-CRYPTO-SITEC access-list traffic for SiteA to SiteC through a Tunnel between B - C
access-list L2L-VPN-CRYPTO-SITEC permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
Where
- OUTSIDE-NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteA SiteC NAT traffic. It is this time tied to the 'outer' interface, as traffic will be coming in and out through this interface to SiteB
- NAT = is the line of configuration NAT0
- L2l-VPN-CRYPTO-SITEA (and SITEC) = are the ACL in the configurations of VPN L2L that defines the SiteA LAN to LAN SiteC traffic should use existing VPN L2L connections.
Site C
access-list NAT0 note NAT0 rule for SiteC SiteA traffic
NAT0 192.168.3.0 ip access list allow 255.255.255.0 192.168.1.0 255.255.255.0
NAT (inside) 0 access-list NAT0
Note list-access-L2L-VPN-CRYPTO-SITEB SiteC to SiteA interesting traffic
L2L-VPN-CRYPTO-SITEB 192.168.3.0 ip access list allow 255.255.255.0 192.168.1.0 255.255.255.0
Where
- NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteC to SiteA NAT traffic
- NAT = is the line of configuration NAT0
- L2l-VPN-CRYPTO-SITEB = LCA in configurations VPN L2L that defines the SiteC LAN to LAN SiteA traffic must use the VPN L2L existing SiteB
To my knowledge, the foregoing must manage the selection NAT0 and traffic for VPN L2L connections. Naturally, the Interface/ACL names may be different depending on your current configuration.
Hope this helps

Thank you
If your HQ has a (rare) dynamic IP address, you must do 3 things:
1. set up a dynamic DNS host name for your HQ VPN peer (dyndns.org, etc..)
2. your counterpart dynamic crypto map using "dynamic peer hqddns.company.com defined".
3. your isakmp for the peer key a wildcard character ("crypto isakmp key addr 0.0.0.0")
If you say that it is an IP change single opposite HQ, then maybe:
1 Add the new IP address to your 'access-list 101' ACL (remember to use a name instead of ACL numbered for readability)
2. Add another encryption with the new IP address isakmp key
3. Add the new IP address as secondary peer:

IPsec VPN site to site between router problem Cisco ASA. Help, please
Hello community,
I'm stuck in configuring VPN site to site between ASA (OS 9.1) and router Cisco IOS (IOS 15, 2 - 4.M4)
Attachment is router configuration and ASA. I also include the router debug output.
It seems that the two parties must isakmp missmatch configuration, but I have already disabled the KeepAlive parameters. I also turn off PFS setting on both sides. But it does not work. I have no idea on this problem.
Please help me. Any help appreciated.
Thank you
I didn't look any further, but this may be a reason:
crypto map mymap 1 ipsec-isakmp dynamic dyn1
The dynamic CM must always be the last sequence in a card encryption:
no crypto map mymap 1 ipsec-isakmp dynamic dyn1 crypto map mymap 65000 ipsec-isakmp dynamic dyn1
Try this first, then we can look further.

the traffic in a vpn site-to-site tunnel restrictions
Hello
I have install a VPN site-to site between an ASA 5550 7.2 (3) and the external network of the contractor. I have set up the VPN using the wizard and it worked fine. The wizard has created the cryptomap acl see below
outside_2_cryptomap list extended access allowed object-group ip 10.0.0.0 LOCAL_IPS 255.255.255.0
where LOCAL_IPS is a group of objects containing our local subnets to be dug and 10.0.0.0/24 is the network of the remote end.
I'm trying to restrict the traffic tunnel at about 6 tcp ports, so I changed the acl (using the GUI as well from the CLI) to the following:-
outside_2_cryptomap list extended access permitted tcp object-group LOCAL_IPS 10.0.0.0 255.255.255.0 PERMITTED_TRAFFIC object-group
where PERMITTED_TRAFFIC is a group of TCP services containing the ports we'd like to tunnel.
As soon as I apply this acl (applied at the other end also) the tunnel down and or end it can re - open.
My question is - how do you restrict what traffic (tcp ports) that you want to send in the tunnel on the SAA?
Thank you
Andy
You have 2 options.
VPN-filter
Or something like that...
No sysopt permi-vpn connection
list of access vpn extended permitted tcp object-group LOCAL_IPS 10.0.0.0 255.255.255.0 PERMITTED_TRAFFIC object-group
list of vpn access deny ip 10.0.0.0 LOCAL_IPS object-group 255.255.255.0
extended vpn allowed any one ip access list
group-access vpn in interface inside
