Last week, I was able to establish a site-to-site VPN tunnel between an ASA 5505 and Cisco C881 router just fine. The tunnel was up and and running for a number of days but today the tunnel is no longer up. I was wondering how, if there are any commands to re-establish or re-initiate the tunnel.
View 3 RepliesAs you can see i have problems with connecting 2 SRP521W together for an VPN tunnel. I tried as much as I can but now i dont know what to do or how and where is the mistake? the connection between these two devices was there last week, after weekend (nothing changed in configs) the connection suddenly was interrupted, without any reason or warning. another day it worked again and 20 mins later connection was dead again...and now it wont establish at all.. here are some screenshots from the vpnconfigs of my devices. one has a static IP the otherone uses FQDN. These are the IKE policies: Here the IPsec Policies: and the GRE policies:
View 10 Replies View RelatedWe have configured a site to site tunnel from our ASA to another organizations Cisco 3030. It appears to have just one way initiation. We can do a ping to a device on the remote site and it will ping just fine. however, when the tunnel needs to be initiated from the remote site, it will not work until we have initiated the tunnel and then everything works.
I continue to see Error processing payload: Payload ID: 1 errors on the ASDM logs.It appears that all the configuration is in place because we can in fact establish the IPSec tunnel unidirectional. And once established, traffic can flow bidirectional.
I have ASA 5505, i configured site to site vpn between central site and remote site and is working. Now the problem is we use remote site for troubleshooting purpose, so we need to create a tunnel from remote site to central site. I need to configure such a way that remote site can craete a tunnel to central site, but central site not able to create a tunnel, it just respond to remote site.

After a while like 5-10 min the vpn site to site tunnel is up and here is the strange thing happening I have all accesslists and tunnel accesslists right I can only access one remote network (Main site Clavister Firewall) trought the vpn tunnel behind the Cisco ASA 5505, and I have 5 more remote networks that I want to access but only one remote network is working trought the vpn tunnel behind the Cisco ASA. I see that when I do this syntax in ASA: show crypto ipsec sa.They had a Clavister Firewall before on that site before and now they have a Cisco ASA 5505 and all the rules on the main site thats have the big Clavister Firewall is intact so the problems are in the Cisco ASA 5505.

All these remote networks are at the Main Site Clavister Firewall.
Remote-access users aren't able to reach our remote network through a site-to-site VPN tunnel between two ASA 5505's.
I've seen several threads about that here, I've run through the walkthrough at [URL] I've taken a stab at setting split tunnelling and nat exemption, but it seems I'm still missing something. Remote-access users can reach the main site, but not the remote site.
Remote-access (vpn-houston) uses 192.168.69.0/24.
The main site (houston) uses 10.0.0.0/24
The remote site (lugoff) uses 10.0.1.0/24
I have a 5505 asa code version 8.3(2). Trying to set up a site to site tunnel with someone and he is asking if I can use ike v2. How do I go about setting up the tunnel to use ikev2? Is ikev2 an option with site to site tunnels?
View 5 Replies View Relatedi have a client who needs to establish a VPN tunnel from his satellite office (Site A) to his corporate office (Site Z). His satellite office will have a single PC sitting behind the ASA. In addition, he needs to be able to VPN from his home (Site H) to Site A to access his PC.The first question I have is about the ASA 5505 and the various licensing options. I want to ensure that an ASA5505-BUN-K9 will be able to establish the site-to-site tunnel as well as allow him to use either the IPsec or SSL VPN client to connect from Site H to Site A. Secondly, I would like to verify that no special routing or configuration would need to take place in order to allow traffic not destined for Site Z (i.e., general web browsing or other traffic to any resource that is not part of the Site Z network) to go out his outside interface without specifically traversing the VPN tunnel (split tunneling?)Finally, if the client were to establish a VPN session from Site H to Site A, would that allow for him to connect directly into resources at Site Z without any special firewall security rules? Since the VPN session would come in on the outside interface, and the tunnel back to Site Z goes out on the same interface, would this constitute a split horizon scenario that would call for a more complex config, or will the ASA handle that automatically without issue?
View 1 Replies View RelatedI am using a Cisco ASA 5505 Here is a description of my topology.
Headquarters = 192.168.201.0
Client X = 172.16.0.0
Datacenter = 10.12.0.0
Site to Site Tunnels:
Headquarters ---> Datacenter
Datacenter ---> Client X
I want to ability for computers in the Headquarters subnet to access the Client X subnet.I have tried setting up a static route to push all traffic destin for 172.16.0.0 to the datacenter, but was unsuccessful. how I can route all 172.16.0.0 through the tunnel.I have tried ading a static route on my ASA but without success.
I do have a 5505 up and running, and passing data... url...Now I am trying to get a IPSEC VPN tunnel working.I actually have it up (IKE phase 1 & 2 both passed), but it is not sending/receiving data through the tunnel.
The networks concerned: name 10.0.0.0 Eventual (HQ Site behind Firewall)name 1.1.1.0 CFS (Public Network Gateway for Palo Alto Firewall - Firewall IP: 1.1.1.1)name 2.2.2.0 T1 (Remote site - Outside interface of 5505: 2.2.2.2)name 10.209.0.0 Local (Remote Network - internal interface of 5505: 10.20 9. 0.3) On a ping to the HQ network from behind the ASA, I get port map translation creation failed for icmp src inside:10.209.0.9 dst inside:10.0.0.33 (type 8, code 0)
I am suspecting that there is a NAT error and/or a lack of a static route for the rest of the 10.0.0.0 traffic, and that I may have to exempt/route the traffic for the HQ network (10.0.0.0), but I haven't been able to get the correct entries to make it work. [code]
I'm currently trying to configure a Site to Site tunnel between an IOS Router and an ASA 5505 running 9.1
When the private subnet of the IOS Router was 10.0.0.0/24 and the private subnet of the ASA was 172.16.1.0/24, it connected fine.
I'm now trying to set it up where both private networks are 10.0.0.0/24, and created network objects, edited the ACL for interesting traffic, and created the twice NAT translation rule, but the tunnels aren't coming up.
There is the IOS Router(R1) and the ASA(F2). In between them is one Internet posing router that is just set up to allow both sides to reach their WAN addresses.
R1 and F2 have private network (10.0.0.0/24) and need to communicate. Twice NAT can be done all on the ASA to allow this, but I must be doing something wrong. The way I understand it, is that the R1 should see the traffic coming from 10.51.0.0/24 and sending to that traffic. The ASA will take that traffic, and the inside network should see it come inbound as 10.50.0.0/24. So the F2 private network communicates with 10.50.0.0/24 and R1 private network sends traffic to 10.51.0.0/24.
I turned on "Debug crypto ipsec" and "debug crypto isakmp" but no output is showing up or giving any hint that it is trying to establish anything.

I am using the Site to Site Wizard on an ASA 5520 and ASA 5505 from the ADSM. Both are using 8.4(5). When you create the configurations. Do you have to follow up the wizard configurations with manual ACL's to allow for traffic from each connected subnet to talk to each other? Or are they automatically generated in the configuration file? Have not been to school yet to properly understand how to create the VPN tunnels from the CLI and what to look for.

I have ran into this problem in the past but clearly I usually change one of the remote host sub net ranges to something other than main site. Now I am in a situation that I just have to configure it this way. I just need some insight before implementation.
Inside (10.10.10.x/24) ASA5505 outside (97.65.x.x) ßà (97.664.x.x) outside ASA5505 (10.10.10.x/24)
Trying to create a site to site tunnel between each location with same sub net. I have found a lot of information about setting up this configuration with 8.3 and later but nothing for the image 8.4 and image 9.1(1) as everyone knows the ACL's and NAT statements are written differently now.
I've got a Cisco 5520, to which is a Cisco 5505 is connected via a Site to Site tunnel.The tunnel works just dandy, with traffic happily being passed to and from my Inside interface.
The issue comes with users connected to the 5505 access our DMZ, it simply refuses to work. I've read many posts about the changes made in 8.3 (which I'm running on the 5520) when it comes to NAT exemptions which I believe is the issue I'm having but I'm not able to implement any configuration to allow my site to site VPNs to connect to hosts within the DMZ.

our customer unfortunately uses a Watchguard.Finally we could establish a site-to-site vpn connection.To test if the connection re-establish again, we cleared our vpn session by "clear crypto isakmp <session id>" and after that "clear crypto sa <ip address of the peer>"After that, the session is down on our site, but the watchguard keeps the Phase I still up, either the deleting messages from our cisco are visible in the watchguard log files.Watchguard helpdesk told us, that the messages are only seen as a deletion message for Phase II, therefore Watchguard keeps Phase I up and running.Here you could see the cisco 7206 log messages aftre the clear commands:
: Nov 10 13:22:06.508 MEZ: IPSEC(delete_sa): deleting SA,
2011-11-10 13:22:06 Local7.Debug 649460013: : (sa) sa_dest= <local peer>, sa_proto= 50,

[code]....
In my opinion, it looks ok and we do not have problems with other VPN devices with this kind of tests.what could be done that the watchguard deletes Phase I, too? Or that an explicit Phase I deletion message is created and sent by our cisco 7206?
