IPsec VPN between two routers - mode ESP Transport and Tunnel mode
Hi experts,
I have this question about the Transport mode and Tunnel mode for awhile.
Based on my understanding of 'Transport' mode is not possible because you always original "internal" private in the IP headers or IP addresses. They are always different as public IP on interfaces enabled with Crypto Card addresses. When encapsulated in the VPN tunnel, the internal IP addresses must be included or the remote VPN router won't know where to forward the packet.
To test, I built a simple GNS3 with three routers laboratory. R1 and R3 are configured as VPN routers and the R2 must simulate Internet.
My configs are also very basic. The R2 is routing between 1.1.1.0/24 and 2.2.2.0/24. It is defined as the gateway of R1 and R3.
R1:

I configured transform-"null" value, while it will not encrypt the traffic.
Then I tried the two 'transport' mode and mode "tunnel". I ping a host in the internal network of the R1 to another host in the internal network of the R3. I also tried 'telnet'. I also captured packets and carefully compared in both modes.
Packets encapsulated in exactly the same way!
It's just SPI + sequence No. +
I will attach my screenshots here for you guys to analyze it. I would be grateful for any explanation. I confused maybe just when it comes to the NAT... I guess my next step is to check if the two modes to make the difference when the GRE is used. Thank you Difan Hi Difan, As you point out the mode of transport is not always applicable (i.e. applicable if IP source and destination is equal to corresnpoding proxy IDs). A typical scenario in this mode of transport is used: -Encryption between two hosts -GRE tunnels -L2TP over IPsec Even if you set "transport mode" this does not mean that it will be used. IOS routers and I blieve also ASA will perform backup even if the mode of transport is configured but does not apply in tunnel mode. I can take a look at your traces to sniff, but all first can you please check if you transport mode on your ipsec security associations? "See the crypto ipsec his" exit you will show the tunnel or transport mode. HTH, Marcin Tags: Cisco Security 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?

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! Concerning Regnier Please note all useful posts 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.

I am trying to solve a practical problem and I can't seem to deliver the VLAN. The presentation is as follows: You have two two routers connected to each other. Each router has a switch and each switch has four related generic PC. Each PC on this switch belongs on its own VIRTUAL local network. Thus,. So A PC on the router/switch 1 1 can ping ROUTER2/switch 2 E PC and it cannot ping all the others. So on and so forth. So I tried to adjust the C VLAN 10 PC to check if the configuration of my work, and it does. But then I tie my router and sub interfaces, set the fa0/1 interface on my switch such as trunk and permit VLAN 10, 20, 30 and 40. Now, all PC on the router can ping each other! That should not happen. Now I don't know what the problem is. Can someone help me? I have attached the docx and the tracer file package. Sorry that I just realized you don't want connectivity between all computers. Which is a relief, because watching your Setup, I didn't see why they wouldn't be able to :-) You must use the ACLs on your subinterfaces to allow only the traffic you want. If you want to allow any PC from any other PC on the same site to ping but only the PC in the same vlan on the other site, then use an outbound acl on the router serial interfaces. If you only want to allow ping between the PC in the same vlan ACL use traffic entering on the subinterfaces. Jon Easy VPN between two ASA 9.5 - Split tunnel does not Hi guys,. We have set up a site to site vpn using easy configuration vpn between ver 9.5 race (1) two ASA. The tunnels are up and ping is reached between sites. I also configured split tunnel for internet traffic under the overall strategy of the ASA easy vpn server. But for some unknown reason all the customer same internet traffic is sent to the primary site. I have configured NAT to relieve on the side of server and client-side. Please advise if no limitation so that the installation program. Thank you and best regards, Arjun T P I have the same question and open a support case. It's a bug in the software 9.5.1. See the bug: CSCuw22886 IPSec VPN between ASAs with same subnet for disaster recovery Hello I need some clarification from you guys. To do disaster EasyVPN tunnels for the Cisco ASA 5505 firewall recovery site. Now, there is only one main site and 3 remote sites. Dr., must use the same subnet that it is on the main site because virtual machines Vmware will be replicated to DR. For the DR we use Double-Take software. What is the best solution for this? I think we could use NAT of Destination on ASAs. Other sites (HQ and remote control) will be directed to only address NAT of the DR and not real which is the same as on the main site. So guys, will this work? We are using IPSec VPN? In packet - trace on ASA, I see that the package is the first using a NAT, and then encrypted, so it should work, Yes? I hope someone can confirm this. I can confirm that this will work certainly, for prior type natting see 8.3: http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml#diag for 8.3 and later it is also achievable. VPN between two computers xp via a dsl connection Is it possible to remotely connect to two computers xp via a dsl connection? Using vpn Hello To establish a VPN connection must act as a VPN server. There are hardware devices (such as some routers) that can do the job. Or try this, http://www.aeonity.com/frost/howto-windows-xp-vpn-server-setup 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. Site to site VPN between ios routers spoke with one asa possible hub? Hi people, I have a couple of series of routers 1841 ios as the rays and a nodal point using an ASA5520 box. Lan to Lan VPN has no problem of communication with nets of void behind the box of the ASA for A rays & speaks B. Problem with inter communication of talking, talking cannot ping spoke to B and vice versa. I now use GRE tunnels for inter communication speaks. I know that this is not a good way to do it if the VPN L2L must increase in size. Is it better average as the use of DMPVPN or a way to activate any function in the box of the ASA? (Tried to use the command same-security-traffic permit intra-interface on the ASA but did not work). Can advice you here other experts? Hello Talk to talk through the Hub of the SAA is possible. And it looks like you were going in the right direction by setting up "permit same-security-traffic intra-interface". Did you get a chance to look at the URL below and configure the Crypto and ACL SHEEP to include remote subnets. Also, did you do the necessary changes to the side talking to reflect the new set upwards. Kind regards Arul * Rate pls if it helps *. Tunnel VPN between two Cisco ASA5505 drops every 15-30 minutes authentication attempts but never reconnects. I have to restart the app dence to back tunnel.
