Cisco VPN :: ASA 5520 - Routing Traffic Between Two Site To Site Tunnels
Feb 24, 2013
I am trying to establish routing between two Site to Site vpn tunnels, both of which are terminating on the same outside interface of my Cisco ASA.
find attached Network Diagram for the same. All Firewalls used are Cisco ASA 5520.
Both VPN tunnels between Point A and Point B, Point B and Point C too are up. I have enabled Same security level intra interface permit command also.
How do i enable traffic originating from LAN Subnets behind Point A to reach LAN Subnets behind Point C without having to create a Seperate tunnel between Point A and Point C
We have ordered a pair of Cisco ASA5520 (ASA5520-BUN-K9).Now there is a requirement to terminate site-to-site VPN from remote site. Do we need VPN plus licence for this and how much it cost?
I wanted to know the maximum VPN client sessions (using the Cisco VPN client) and Site-to-Site VPN tunnels that I can connect to my ASA 5505 simultaneously.
In other words, if I have x VPN clients and y Site-to-Site tunnels, at any time, does x + y have to be <= 10 (Total VPN Peers)? If yes, can I upgrade to the security plus license to increase the Total VPN Peers to 25?
Licensed features for this platform: Maximum Physical Interfaces : 8 VLANs : 3, DMZ Restricted Inside Hosts : Unlimited Failover : Disabled VPN-DES : Enabled [Code]...
Question on ASA VPN tunnels. I have one ASA 5510 in our corporate office, I have two subnets in our corporate office that are configured in the ASA in a Object group. I have a site to site IPSEC tunnel already up and that has been working. I am trying to set up another site to site IPSEC tunnel to a different location that will need to be setup to access the same two subnets. I'm not sure if this can be setup or not, I think I had a problem with setting up two tunnels that were trying to connect to the same subnet but that was between the same two ASA's. Anyways the new tunnel to a new site is not coming up and I want to make sure it is not the subnet issue. The current working tunnel is between two ASA 5510's, the new tunnel we are trying to build is between the ASA and a Sonicwall firewall.
I have an issue with 2 site to site VPN tunnels from a RV042G router. The issue is for both VPN tunnels is that in the logs, it is showing that when the RV042G router is trying to establish the tunnel, it is getting a response from the remote gateway internal address and not the Public address of the remote gateways. On the remote gateways I have other site to site VPN's terminating fine and the tunnels are passing traffic. I only have an issue with the RV042. On the VPN Tunnel page it shows for both tunnels waiting for connection. This is an output from the log of the RV042G

VPN tunnel terminating on 203.43.XX.XXX is a Checkpoint firewall running R70 software version?VPN tunnel terminating on 203.47.XXX.XX is a Cisco ASA 5510 running ASA 8.2.4 software?As stated above, I have other VPN tunnels working fine. This RV042 is a replacement router as the original router suffered a power surge.
We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ). When Remote vpn users try to connect to computers located on the distant end of site-site VPN, their request failed. I tried No-Nat between remote vpn private IP to the remote site private IP, also stated the same in Split tunneling. I cant find even the tracert, ping also timed out.
We 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'd like to create a site-to-site vpn between an SRP527 and an other vpn gateway. The problem is i don't see how to route all traffic from the local network (network defined by the lan ip interface of the SRP527) to the other vpn gateway? It seems to be only possible to define the destination network (accessible via the vpn) with ip/mask (but only for "small" network: for exemple i tried with 10.2.0.0 mask 255.255.0.0 and it's ok but i tried with 10.0.0.0 mask 255.0.0.0 -> it's not working. I obtain the message "invalid ip")
I have a setup with a pair off ASA5510 on the central site, and approx 20 sites with ASA5505.A couple off network are configured as site to site tunnels to every remote site.Its very stable, but the last year or so ocassionally one of the tunnels go one-way.Just like one of the nat exeptions suddenly stops working.I can see the remote side transmitting packets, but no answer.Central site is running 8.22, want to upgrade but have to mount more RAM.The only cure i have found is to reboot the central pair off ASA5510, not very popular as all 20 tunnels goes down.
I'm working with a client who has a site to site VPN between the main office and a branch office. The main office is 192.168.200.0/24 and the branch office is 192.168.1.0/24. The issue is when the branch office users use the VPN in they receive a 192.168.200.x address, however, they cannot access a server or any other resources at the branch office.
They have a SSL-VPN 2000 connected to a TZ100 at the main office and a Juniper device at the branch office. I did try setting the Tunnel All mode on the NetExtender but that does not allow me to access the resources at the branch office. Additionally, those users at the main office can access the resources at the branch office without getting on the VPN.
I have vpn-concentrator on vyatta, 8 cisco 881w and 2 cisco 1941 with vpn site-to-site connected to vyatta. They all are in one ISP's vlan native L2 level.
I user pre-shared key, aes128 and md5 hash.
Traffic goes both sides, everything is okay, i strated cacti monitor of traffic and CPU, started netflow analyzer.
Sometimes one ipsec connection between any of branches go down, it doesn't have any extra CPU load, not more then 20-30%, no huge traffic but somewhy i recieve phone call like "i can't reach server" i check on vyatta - tunnels are down with one router, i do "reset vpn ipsec-peer N" and everything is ok.
I mentioned that when I added "keepalive periodic 10" on ciscos, tunnels started go down more often, for exmaple usually I recieve 1-2 phone calls during a day, whan I added this command, i started to recieve 4-5 phonecalls from branches.
it's always random tunnel down branch, today it was one 1941 and one 881w, yesturday it was 3 881w during all day
We 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?
Have asa 5520 ver 8.0(4) I have vpn client access created and working I have l2l vpn created and working with another set of asa The issue at hand VPN client from internet connects and authenticates, this client can access Site A's networks with no problems. However vpn client on Site A ASA can not access Networks through l2l tunnel located at Site B.
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. When I transfer a file from the Sita A to Site B I get a transfer rate of 130KB/S.
I recently faced an issue at work. Clients want to make ipsec site-to-site vpn redundant. I have 2-asa-5520 working in a stack. Is it possible to configure site-to-site vpn in a redundant mode, like first peer ip address is x.x.x.x and secondary is y.y.y.y (backup) ?
I 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?
Got an ASA5505 connected to another endpoint running IPsec and being NAT'd at each end to a 10.0.0.0/24 network. I can pass other types of traffic through the ASA 5505 but not RTP traffic. The moment it is NAT'd and hits the firewall rules it gets denied by the default deny at the bottom of the list.
Currently the rules are as follows
Incoming External allow ip any any allow tcp any any allow udp any any default deny
[code].....
It wont allow us to setup a voip call...however when the same call manager sets up a voip call NOT using this ipsec tunnel it works just fine.

I have some challenges with a VPN config I recently setup for a client.I have at the HO the following:
- 1800 router - Avaya phones and Gateway - 1MB radio internet access
At the BO(branch office), i have:
- 871 Router - Avaya phones - 256k internet bandwidth
The only reason we setup the VPN in the first place was for the phones at the BO to be able to connect to the gateway at the HO and also able to make calls and receive calls as if the phones were at the HO.The phones at the BO successfully register to the HO, but are unable to recieve calls and dial out. Everytime I try to make a call, the phone displays a "connecting..." message. [code]
All have a Security Association Lifetime (Time) of 8 hours. All have a Security Association Lifetime (Traffic Volum) of 4608000 KiloBytes.
We have an issue when we do Oracle logshipping between the sites.
This triggers the Traffic Volume rekey as can be seen by this entry in the logs: -
%ASA-7-702307: IPSEC: An inbound L2L SA (SPI= 0x169FA1C1) between and (user= ) is rekeying due to data rollover.
However it does not appear as if the renegotiation is occurring properly. Within 10 to 15 minutes data stops being transmitted along the link, even though the IPSec tunnel still appears up in the ASDM GUI.
The 'fix' for this is that we are using is to login to the ASDM GUI and bounce the link by going to Monitoring => VPN => VPN Statistics => Sessions => IPSec Site-to-Site. Then select the appropriate VPN tunnel and click on 'Logout'. This forces a link renegotiation which works fine.
I have attached a logfile from the local ASA (there's nothing in the logfile of the remote ASA until we bounce the VPN tunnel).
I have 2 ASA 5505 Firewall, I Configured Site 2 Site VPN no both the fitrewall, as i have a dual ISP, i am able to create the tunnel with primary but once my primary is down i am not able to create the tunnel with back up ISP. During the troobleshoothing by typing Show isakmp sa and Show ipsec sa, i can see my tunnel is up, but not able to decap the packets.
At the main site, I have 3 5508 WLCs each part of a mobility group (wlcMain-MG). In NCS, under "System/Mobility Groups" for each controller, I see each controller listed as "local" with the other Controllers listed with the group name "wlcMain-MG". None of the SSIDs are "anchored".
I have a new site with a 2500 series WLC that I would like to push out 2 SSIDs. This site contains two customers. One customer is the Main customer with the second customer leasing space.
I have the Cust2 WLAN at the remote site set to have traffic egress out of a local interface on the 2500 WLC (this traffic is then tunnelled back to their Main location via an ASA which houses the DHCP scope for that vlan). I can connect to this SSID, obtain an IP Address off the ASA and am tunnelling without issue.
For the Cust1 WLAN at the remote site, I would like to broadcast an SSID from the Main location on those same APs which are registered to the 2500. It is my understanding, that I anchor the SSID at the Main site and identically configure the SSID at the remote site. This will allow the end user to authenticate to the RADIUS server at the Main site and be placed upon the correct vlan (we are using DOT1x and dynamic vlans).
For my test, I am starting simple. I have created a test WLAN with no authentication. At the main site, on 5508 WLC3, I have created the test WLAN, and placed the interface into a low security vlan (call it VLAN-low). I have anchored this test WLAN to that controller. At the remote site, I have created the same WLAN (but placed it into the management interface for now - the VLAN-low does not exist at the remote site) and configured that WLAN to anchor back to the WLC3 at the main site. I am unable to obtain an IP address from the remote site. I have placed the remote site WLC in the wlcMain-MG as well. How close does the code need to be on the controllers - the 5508s are at 7.0.116.0 and the 2500 is at 7.0.220.0? What could I be missing?
A user with Easy VPN client connects to a 876 ISR (router A). This router also has a site-to-site VPN to another 876 ISR (router B). What I want to achieve is that the user dials in to router A and can access the network on the remote end of the site-to-site tunnel (router B) In diagram:
user (192.168.18.x) - Easy VPN - Router A (192.168.16.x) - sitetosite - Router B (192.168.17.x)
I have added routes in router B to the 192.168.18.x network with router A as next hop, but I can't reach the other segment.
I have set up a site to site VPN from a Cisco ASA 5580 to a Netgear FVS318v3 using 3DES, MD5, GH 2 and preshared key, My VPN Tunnel is always up, I can see on the netgear and firewall ASA that the connection VPN is established at both phase 1 and phase 2 level, but no traffic is flowing through the tunnel sometimes. The only way I can see the traffic passing, it is reload the tunnel on the firewall netgear.the configurations on the firewalls are same.
I can see the requests of the ASA Red_Lan to server located at the remote site, behind the Netgear Firewall and observe traffic on the ASA but on the outside/inside interfaces of the firewall Netgear there are not traffic. Is necessary to configure and others parameters for VPN?
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 want to configure QoS for voice traffic over a site-to-site VPN tunnel. I have a Cisco 851 router on the branch end and a Cisco 1800 router at the HQ. The setup is an Avaya Gateway located at the HQ and the idea is that the phones at the branch office are connected over the VPN tunnel to the gateway at the HQ.
I have a 1MB internet link at the HQ from a service provider and 256kbps internet link (from a different service provider) at the branch office. The branch office has just 3 users.
I have a functioning site-to-site VPN between two ASA 5505 appiances. Sub-net on one side is 192.168.20.0/24 (inside I/F) and on the other side is 192.168.30.0/24 (inside I/F). VPN is built over public Internet (outside I/Fs of those two ASAs).
Now I connected another subnet on 192.168.30.0/24 - e.g. 192.168.35.0/24. Traffic from 192.168.30.0 subnet is routed to 192.168.35.0 via Gateway at 192.168.30.250 IP.
My task is to make packets from 192.168.20.0 subnet to go to 192.168.35.0 subnet and vice versa.
I setup a static route on 20.0 ASA's Inside interface as 192.168.35.0 255.255.255.0 to 192.168.30.250. I also created NAT examptions for outbound packets from 20.0 to 35.0 and inbound as well. I also added destination network of 35.0 to VPN cryptomap traffic selection (on both ASAs).
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 am configuring Cisco ASA 5520 site to site vpn with Avaya VPN Phone? According to Avaya, the Avaya 9630 phone acts as a VPN client so a VPN router or firewall is not needed.
I'm trying to establish site to site VPN between ASA5510 to ASA5520, scenario. [code] our Vendor said to nat the local network to specific ip and use that ip as local pool,here the configuration details [code] i create static nat but its doesn't work for me phase 1 is not up, how to create nat local network to 10.10.10.10.
