Redundancy of site to Site VPN
Hello
I have two ASA 5510 configured with tunnel from site to site. on both sides of the ASA 5510 I set up the links of redundancy (completed 2 ISP links) which works very well.
Now, I need to configure site-to-site vpn for the help link.
Please suggest me how to configure the redundancy of a site on both sites.
Kind regards
Ramanantsoa
I don't know exactly the topology of your network, but it is possible to define two peers for site-to-site VPN connection. You can do this in
toSanJose 20 ipsec-isakmp crypto map
correspondence address card crypto 20 90 toSanJose
toSanJose 20 set transformation-strong crypto card
card crypto toSanJose 20 peers set 209.165.200.229 125.126.127.22
The first pair is always given priority, in case if it is not available it failovers exchange of a second.
It will be useful.
Kind regards

Troubleshooting IPSec Site to Site VPN between ASA and 1841
Hi all
in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.
I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).
I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.
It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),
On the ASA:

It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.
Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto. (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.
I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!
It's the running of the 1841 configuration

Joerg,
ASA receives not all VPN packages because IOS does not send anything.
Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)
The problem seems so on the side of the router.
I think that is a routing problem, but you only have one default gateway (no other channels on the router).
The ACL 100 is set to encrypt the traffic between the two subnets.
It seems that the ACL 101 is also bypassing NAT for VPN traffic.
Follow these steps:
Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.
I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.
Federico.

Site to Site VPN Cisco IOS 1941 15.0 (1) M1
Hello
I am currently developing a Site VPN site between an ASA and a router in 1941. Configuring VPN on the SAA seems to be ok, because it works without problem with router 1841 with IOS 12.4 to the other site. The same VPN configuration on the new router in 1941 with M1 IOS 15.0 (1) does not work. It seems that the access to the crypto map list is the problem. The router never start the VPN connection. When the ASA attempts to establish the VPN, the debugging of the router log shows:

IPsec Site to Site VPN multisession?
Hi people.
I recently faced a problem at work. Customers want to dismiss ipsec site to site vpn. I have 2 asa 5520 working in a stack. Is it possible to configure the vpn site to site in a redundant mode, as the first ip address is x.x.x.x and secondary is y.y.y.y (backup)?
Thank you much in advance.
Hello
You can define several counterparts in the card encryption, see:
http://www.Cisco.com/en/us/docs/security/ASA/asa72/command/reference/c5_72.html#wp2066090
You can define several tunnels and leave the routing protocol to choose the best route.
Hope this helps,
Bastien.

IPsec site to Site VPN on Wi - Fi router
Hello!
Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?
I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?
See you soon!
Michael
I suspect that.
Thank you very much for the reply.

Site to site VPN, I need all internet traffic to exit the site.
I have 2 sites connected via a pair of SRX5308
A = 192.168.1.0/24
IP WAN = 1.1.1.1
B = 192.168.2.0/24
IP WAN = 2.2.2.2
Now what I need to do, is to have all traffic from B to go to the site one even traffic destined to the internet. That is, I need internet traffic out of our network with the IP 1.1.1.1, even if it is from the network B.
On my I have set up a route 1.1.1.1 of the ISP, then a value by default 0/0 to 192.168.1.1 it ASA knows how to get to the peer VPN is a more specific route, but sends everything above the tunnel, at the remote end which then hairpin of ASA routes internet outside its own WAN port traffic.
I can understand though not how to so the same thing on the pair of SRX5308 they either don't raise the tunnel or internet route to the local site address B.
Anyone have any ideas?
I need to do this because we are logging and monitoring of internet traffic to A site via tapping from upstream to various IDS solutions and will not (cannot) reproduce this to all our remote sites.
Thank you
Dave.
After some more thought and testing I came up with a workable solution to my own problem. I'll share it here in case it can help others.
(1) use the wizard at both ends to implement a normal VPN that connects the two segments of network 192.168.1.0 and 192.168.2.0
(2) go to site VPN - VPN policy remote router192.168.2.1 and click Edit
(a) disable Netbios
(b) select "None" from the drop-down list the remote IP address.
(c) to apply the change
3) go to the VPN-> VPN policy on the head end site (192.168.1.1) and click Edit
(a) disable Netbios
(b) select "None" from the drop-down list the local IP address
(c) to apply the change
Now all the traffic wil go down the VPN tunnel and exit to the internet on the site of head end. Hope this helps others with the same question.

I have a VPN site-to-site existing on Azure and Azure a new subnet created on the local network that must be able to reach.
I added the new subnet within azure for the VPN and add a static route on the RRAS server win 2012 for routing.
On the initial installation of a RRAS-Site VPN site (I didn't configure it) I think the interesting traffic specified must be sent through the VPN Tunnel, but I knew how to specify the new subnet via RRAS, I don't want to delete and re-create the VPN Site to Site.
Y at - there anyone who can help please.
Thank you
Philippe

IPSec Site to Site VPN Solution needed?
Hi all
I need a solution to provide full connectivity to one of my clients. I created two IPSEC Site to Site VPN, one between the INFO and RITA and second between NIDA and RITA. I can access RITA machine that is 172.16.36.101 at the INFO and 10.0.0.5 to NIDA.
Now, I need to give access to my customer INFORMATION to direct NIDA 10.0.0.5 without established VPN machine to NIDA 10.0.0.5 of 172.16.36.101 access.
Could you please give me the solution how is that possible?
Concerning
Uzair Hussain
Hi uzair.infotech,
Looks like you need to set up a grouping between the 3 sites, at the end of that your topology will look like this:
INFO - RITA - NIDA
You can check this guide that explains step by step how to configure grouping:

Hope this info helps!

Thank you
Next step will be sending real traffic, or just run a package Tracker to ensure that traffic flows very well:
entry Packet-trace within the icmp 192.168.15.x 8 0 172.10.10.x detail
If all goes well, you should be good to go.
Hope this info helps!

Improve SA540 site to site VPN perforamce
Site has SA540: 50 M / 50 M DSL (country A) (15 users)
Site B SA540: 2 M / 520KB ADSL (country B) (10 users)
MTU: 1464 (Test on frame of ping)
We custom applications and server work on port 80 of services, it comes to legacy applications and need to call the java prompt back.
We do server on Site A and alos configuration port front of WAN custome application server.
I find the Site B use direct http services over the Wan just need 5-10 seconds to launch the applaciton
On the same machine, we use the site to site VPN to connect to the application, that it will take about 15 ~ 20 seconds or more, alos sometimes cannot load success via VPN enforcement, how can I improve it? Or participate in any suggestion that I have to pay?
Thank you
Hi yururuhgftdy, your vpn is only as good as the slowest connections. If you want to improve performance, update the connection from the other end.

Remote monitoring Pix on IPSEC site to site VPN
I have a few 501 s PIX that connect through the VPN site-to site. We use Orion NPM and I can't add monitoring. I was able to add remote routers that connect through site-to-site VPNs. I guess that the rules of the Pix security/NAT prevent that. The configuration of the remote Pix is attached.
You need on the 2800...
access-list 131 permit ip host 172.16.30.19 24.172.234.126

Cisco 3640 to the PIX 501 site 2 site VPN performance specifications.
I intend on creating a site-2-site VPN in Star configuration with a Cisco 3640 as the hub and PIX 501 at the remote sites. My question is around the plug that I read.
.
The specifications for a PIX-501-BUN-K9 tell PIX 501 3DES Bundle (chassis, SW, 10 users, 3DES).
.
A question is what really "10 users. Which is the limit of the number of concurrent sessions, I have on the VPN at a given time, or that it means something else?
.
I also read the specs say that the Maximum number of VPN tunnels that can support a PIX 501 is 5. Because I'm not going to make a tunnel between the PIX 501 at the remote site and the 3640 on the central site, I think I would be OK. Is that correct or is the max value talk the maximum number of concurrent sessions on the tunnel tunnels?
.
Thank you.
UDP traffic always creates a session in the PIX so that the return traffic will be allowed in. The UDP timeout is 2 minutes but IIRC. If you go around NAT with a statement of "nat 0" should not create an xlate I think.
The real time is hard to say really, probably around 2 minutes for a UDP-only user, you would probably make a few 'local sho' orders on the PIX to really see for sure however.

SA520w routing through site-to-site VPN tunnels
I have several offices that are connected using site-to-site VPN tunnels and all will use the SA520W (firmware 2.1.18). I currently have 3 routers in place, router tunnels created for the router B and c of router. I need assistance with the configuration to allow the guests to router site B get to the router site C. I have attempted to add a static route, but get a destination unreachable host trying to ping. Also, if I connect to the router site has via the Cisco VPN client, I'm not able to get resources on each site, B, or C.
A - the site 10.10.0.0/24
Site B - 10.0.0.0/24
Site of the C - 10.25.0.0/24
Any help is greatly appreciated.
So, that's what you have configured correctly?
RTR_A
||
_____________ || ___________
|| ||
RTR_B RTR_C
Since there is no tunnel between B and C there is no way for us past that traffic through RTR_A for two reasons. The most important reason is that subnet 10.25.0.0/24 (rtr_c) is not allowed to pass through the IPSec tunnel (it's okay to IPSec?) of rtr_a ==> rtr_b. You can't just add a statement of road because your addresses are not routable which is the reason why it fails.
Your only option is to create another tunnel between rtr_b and rtr_c. This may not be the ONLY option, but you should get what you need.
I hope this helps.
