I have multiple site-to-site vpns using ASAs 5510 and 5520, tunnels were configured 3-4 years ago, and all these 3-4 years one vpn tunnel hangs until I clear isakmp sa peer. When I say hangs, I mean I can see the tunnel is UP and MM_ACTIVE with sh crypto isakmp sa, but I can not ping the remote subnets. When I clear the tunnel, it somes up again and communication is successful.

View 2 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.
What are the possibilities that exist for running a site to site vpn in our environment with the following infrastructure Cisco ASA 5520 - running on a multiple context mode
-Cisco 3750 switches
-Microsoft TMG
I believe these options are limited in terms of providing end point for VPN.Is there a VPN module that we can buy for 5520 to run IPSEC VPN?

We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ).

View 1 Replies View RelatedI am building a site to site VPN from our headquarters to a customer. I am using an ASA 5520. The customer is using Cisco 3945 routers. The customer has two VPN termination points. The customer requests that we make one of their termination points the primary VPN connection and make the other termination point the backup in the event that the primary VPN fails. How do I configure this on the ASA? Does the below configuration fulfill this goal?
View 3 Replies View RelatedWe have 3 sites, with a Cisco ASA 5520 at each location.
HQ (Headquarters) internal network: 172.16.110.0/24,
DR (Disaster Recovery) internal network: 172.16.120.0/24
BO (Branch Office) internal network: 172.16.150.0/24
HQ and DR have a 100Mbps permanent MPLS link between each other.Branch Office has a Site 2 Site VPN connection to HQ. If it fails, it establishes a Site 2 Site VPN connection to DR. This works perfectly.Now the routing issue... There is no route to the BO in the routing table at HQ/DR. The default gateway is used to reach the BO and that works for HQ when the VPN is between HQ/BO. If the VPN fails over to DR/BO, HQ can't reach BO anymore.I need to have some kind of conditional route injection from the ASA where the VPN is established. I was considering a tracked static route, but I was wondering if the S2S VPN itself has a functionality to do so. I thought the Reverse Route Injection was it but it's enabled on our crypto map and doesn't seem to work...
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.

View 36 Replies View RelatedI try configure VPN site to site, with ASA 5520 and Ruter 891.The topology is LAN-->ASA 5520-->INTERNET<--ROUTER 891<--LAN.
The configuration of the VPN site to site on ASA5502 is UP, but in Router 891, I dont understand the commands. url...
I have a pair of ASA 5520s configured in failover mode that also acts as VPN endpoint for about 25+ site to site ipsec VPNs. Of the 25 sites, 2 sites consistantly are having VPN issues while the other sites never have this issue.
For example, at a branch office the network is 192.168.1.0/24, and at the headquarter the ASA has an interface with network 192.168.254.0/24. VPNs are setup to tunnel all traffic destined to the headquarter network 192.168.254.0/24 and a couple of other networks with public IP addresses not directly connected to the ASA.
When the issue occurs, I can ping anything in the 192.168.1.0/24 or the 192.168.254.0/24 range across the VPN, but I cannot ping anything in the public IP range. ASDM reports that the tunnel is up. Restarting the routers at the branch offices do not work.
So far, I have been able to resolve the issue whenever it occurs by doing the following, however this issue happening more and more frequently:
first, try killing the VPN tunnel and wait for the router and ASA to re-establish the tunnel, sometime that works. If that doesn't work, I would failover to the standby ASA. Sometime even that doesn't work, then I have to reload the standby ASA before I failover to it.
All these site to site VPNs are setup the same way for the same purpose (to tunnel ad/exchange traffic), and this issue only happens to 2 of the branch offices which are using different ISPs - I even switched one of the 2 offices to a different ISP and router recently - still have the same issue.
I'm having slow performance thru a Site to Site VPN. I have an ASA 5520 in each site with the version 8.2(4) in both ASA's.I have a 20Mb internet service in one side and in the other side I have 50Mb.

Can the ASA 5520's support dynamic IP for site to site VPN
View 1 Replies View RelatedWe have a site to site client that is having issue with intermittent disconnects. The Main endpoint is a CIsco ASA 5520 8.4.3 and the remote site has a a Cisco ASA 5505 8.2.5.
If we have a disconnect, we can "logout" of the Main ASA and the connection seems to find itself and traffic will flow. This take place about every 1 - 5 minutes but if you reset the crypto (which I am assuming you do) by logging out under the Logging Monitor Session - ikev1 sessions. It all starts right back up.
I am stumped. At first I thought MTUs but I am not sure that is the answer.
I configurated Ipsec vpn at asa 5510. my inside ip 192.168.10.156my public ip: 85.x.x.xmy peer ip : 62.x.x.x
the project is that:
the remote site want the interesting traffic like that:
source ip 172.16.1.104 can access destination ip 10.0.154.27
My inside ip is 192.168.10.0/0 and i can not to change it 172.16.1.0/24 and i can not to add this ip at my network.
Our Headquarter (asa 5510) is running a site to site vpn connection with a Branch office (router 2811). All remote users are accesing the internet through the VPN and also accesing headquarter file servers.I want to know if there is a way for some remote users to be able to use the vpn for accesing the file servers but to access the internet through the branch office. The rest of the remote users will be still accessing the internet through VPN.

View 5 Replies View Relatedwe have two ASA 5510s one in 8.4(4) and one in 8.2(5) in a site-to-site VPN setup. All internal traffic is working smoothly.Site/Subnet A: 192.160.0.0 - local (8.4(4)) Site/Subnet B: 192.260.0.0 - remote (8.2(5)) VPN Users: 192.160.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible.
Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise.There are also some weird NAT rules that I am not happy with that were created after I upgraded Site A ASA to 8.4
Site A internal: 192.160.x.x External: 55.55.555.201(main)/202(mail)
Site B (over site-to-site) is 192.260.x.x External: 66.66.666.54(all)
I pretty much just have the basic NAT rules for VPN, Email, Internet and the site-to-site.What do I need to add for the VPN to be able to access the site-to-site network?

I setup RA-VPN under local asa 5510 IP pool (192.168.127.0/24) and all was working fine. I got internet and local network access.
Then i have 5 site to site VPN working fine but when im traying to access to those L2L VPNs from the remote acces client im not able to do that. So after that i decided to obtain IP addresses from my DHCP server so i can obtain IPs from my local network (172.17.16.0/16) and then access normally to the VPN site to site. But the surprise was that the VPN cisco client is getting local IP address (172.17.16.222) perfectly but im not able to access even to my local network.
I have the same-security-traffic permit inter-interface same-security-traffic permit intra-interface enable.
