Cisco Firewall :: Site-to-Site VPN Between ASA 5510 And 5505 Configuration
Apr 18, 2013
I am not very experienced with Cisco networking.
Here is the situation.
Site A - headquarters 192.168.1.x
Site B - remote office 192.168.20.x
Site C - remote office 192.168.30.x
Site A - ASA 5510
Site B - ASA 5505
Site C - ASA 5505
Site-to-site VPN is established and works between A and B, A and C. Users would like to establish a tunnel between B and C to work on a common project and the data is on Site B.
I tried configuring the S2S VPN with pre-shared keys on both firewalls at sites B and C but in the end it is not established (I cannot ping either side). I used the Wizard interface multiple times and one time the CLI. I generally followed the settings chosen between the headquarter and the individual remote sites and tried to replicate them. Obviously I have made a mistake somewhere.
Could there be any limitation on the ASA 5505 in terms of licensing and the number of S2S tunnels?

I am try to configure ASA 5510 with 8.3 IOS version.My internal users are 192.168.2.0/24 and i configured dynamic PAT and are all internet .
i want configure identity NAT for remote access VPN.Remote users IP pool is 10.10.10.0 to 10.10.10.10
i know to configure NAT exemption in IOS 7.2 version. But here IOS 8.3 version. configure NAT exemption for 192.168.2.0/24 to my remote pool( 10.10.10.0 to 10.10.10.10).

We have a Cisco ASA 5510 at our main office that makes connection with a 5505 at our other office using site to site VPN. (works)
Now for the question,
we want to access our other office from the main office but we wont want them to have access to our servers etc. so basically we want to control them but they shouldn't have the rights to control us.
Is this possible with a site to site VPN? and how to do it.

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.

I just try to build a Site-to-Site VPN over IPSec between a ASA5505 and a ASA5510. But it don`t want to work. Here are the config`s of the ASA 5505 and ASA5510:

I have an ASA 5505 and a 5510 that had a VPN connection working until the external ip address of the 5510 changed. I deleted the existing VPN connection on the 5505 and recrerated it with the new address of the 5510. I can see that the vpn lin is established, but the 5505 isn't transmitting any bytes. I looked in the Monitoring > VPN > VPN Statistics > Sessions and I see that the link is established and the bytes Rx is working, but the bytes Tx stays at 0 (this is on the 5505, on the 5510 there are no Bytes Rx, but there are bytes Tx). I don't think the problem is with the 5510, because that router has a vpn connection to another 5505 which is working fine.
config for the 5505 where the VPN isn't working: The VPN in question is the one with the ip address 207.229.xx.xx the other VPN (208.118.xx.xx is working, but is no longer needed) [code]

I have a problem with a Site to Site VPN configuration between an ASA 5505 and a 1941 ISR. I can get tunnels without NAT up without any difficulty, but there are several remote sites with the same inside network which need NAT to traverse the tunnel from those ASAs to the ISR, which is acting as a hub.
The tunnel from ASA (1) to the ISR vpn router is working perfectly, but the tunnel to ASA (2) is not working. From what I can see in an ASA packet trace that tunnel is sending the NAT traffic out to the internet, rather than across the tunnel. I have tried using the NAT subnet as the interesting traffic for the tunnel, the LAN subnet as the interesting traffic for the tunnel, static NAT entries, policy NAT entries, but all have failed. [code]
How do I get the tunnel to see the NAT IP addresses?

I have a ASA 5510 at our corporate HQ that has one site to site VPN. I need to add 6 additional site to site VPN's to this ASA for our remote branches. How can I add them without affecting the existing site to site VPN? The 6 site to site VPN's will all have the same settings however these settings are different from the existing site to site that I already have set up. How can I set it up so the 6 additional VPN's use their own crypto map and all use the same settings?

I have a ASA 5510 that has multiple site to site VPNs. I need to create an additiona site to site VPN but only allow 1 host to access and traverse the tunnel. The network is on a 192.168.5.x but the host that will need to access this tunnel needs to be on a 172.16.33.x network. I dont want any other traffic allowed to access or traverse the VPN tunnel for this host. How can I set this up?

I would like to know both Cisco 2901 or 2921 router and Cisco 5505 ASA can build site to site VPN.
1) what is the different to build site to site VPN between router and firewall ?
2) which is the best choice if using in site to site VPN connection ?

I have a request to establish a site to site VPN with a customer. While collecting the information I give them our local network subnet which is a private subnet (192.168.5.0). They asked me if I could give them a public address instead. They can not work with the 192.168.5 subnet. Is this possible?
My side of the VPN is an ASA 5505 running 8.2(2). The other side i believe is a Checkpoint.

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.

We have a client that has a Cisco 1801W Firewall that is setup as a site to site VPN terminating to a Cisco ASA 5505. The tunnel is up and established, I can ping from both sides of the tunnel.
The problem is the clients behind the Cisco ASA (192.168.2.x) cannot reach certain ports behind the Router (192.168.1.x). The main thing we're trying to do is browse via UNC path (ex: \192.168.1.120 from a 192.168.2.x machine).
I got 3389 working after I changed the - ip nat inside source static tcp 192.168.1.120 3389 y.y.x.x 3389 route-map DM_RMAP_1 extendable Modified the command to include the public IP instead of interface FastEthernet0
I believe it has something to do with the way NAT and route-maps are setup currently but I'm not familar enough with them to make the changes. I worked with Cisco to ensure the VPN tunnel was fine and it's something security related on the Router.
Here is the configuration (removed a few lines not necessary. y.y.x.x = WAN IP of Router x.x.y.y = WAN IP of ASA).
Building configuration...
Current configuration : 23648 bytes

version 12.4

I have weird problem with a Site to site VPN tunnel from a Cisco ASA 5505 to an Clavister Firewall.When I restart the Cisco ASA 5505 the tunnel is up and down,up, down, down, and I get all strange messages when I see if the tunnel is up or down with the syntax: [code]
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. [code]
All these remote networks are at the Main Site Clavister Firewall.

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

We have got site to site VPN configured between local site with PIX515 6.3(5) and remote site with ASA 5505 7.2(4) . Because of very unreliable internet connection in remote site , we have added new ISP link which we want to use as redundant link .i understand ASA 5505 can be configured with two ISP link with SLA monitor method for redundancy as per this document ,[URL]
my question is how do i set up this pix 515 to have redundant VPN tunnel with remote site (when primiary ISP link fails in remote site and secondary ISP links takes over ) . I was thinking of using PIX 515 with 2 peers in same crypto map used for that sepcific site to site vpn tunnel,not sure that is the right way or not though.But how would i configure ASA 5505 to use backup interface(where secondar isp router conects ) to particitae in Site to site Tunnel .

We are setting up a new phone system using the UC540 with a VPN connection between 2 buildings using 2 Cisco ASA 5505's at either end.The problem I am having is getting the phones at the remote site to connect to the UC540 at the main site.
Phones/Computers (10.0.1.0/24) -- ASA -------------VPN Tunnel------------- ASA -- UC540 -----------Data Vlan1 (10.0.0.0/24)
|------Voice Vlan100 (10.1.1.0/24)
What i am told by UC500 support is that the phones at the remote site will connect if they have connectivity to the TFTP subnet on the UC540, which is 10.1.10.0/30 I added the static route on the ASA and I can ping the 10.1.10.1 TFTP server on the UC540 from the ASA, but not for any other device on the 10.0.0.0/24 network, such as the DC. I added the static route there and was able to ping, so something in the ASA seems to be preventing it.
I also can't seem to get the ASA at the remote site to ping 10.1.10.1. I've tried adding the static route there in hopes it would forward it through the VPN tunnel.

I have an issue with my site to site VPN. I have 4 sites connected to my main HQ site via Cisco ASAs 5505 firewalls. The problem is that once and then the sites disconnected from my main site. This disconnection is not happening at the same time for the the 4 sites. For example, it might be different site each time disconnected.

I have a site to site VPN configured on a asa5505. The tunnel is up and the interesting traffic is successfully being encrypted. The issue is that when inbound traffic originating from a subnet outside of the encrypted range destin to the subnet within the encrypted range, the return traffic is sent into the tunnel and obviously fails.When traffic from 1.1.1.0/24 to 10.2.2.0/24 traverse the firewall the return traffic goes into the tunnel but it doesn't have the correct match parameters?Am I missing something? I'm expecting that only traffic matching the crypto map will use the tunnel and all other traffic will utilize the default route.

I'm trying to configure a Site-to-Site VPN in a Cisco ASA 5505 firewall which is behind an ISP router (Cisco 800 Series) configured in routing mode (not bridging) and with a static nat of all the ports to the firewall (avoiding bridging mode of the router). [code]

I am trying to setup a site to site VPN between ASA 5510 and SSG 140 firewall. ASA end of the VPN is having dynamic public IP address. I tried sending hostname as peer identity on ASA by changing the IKE parameter setting but SSG somehow is not able to match the hostname of remote peer and reporting remote as unrecognized peer. Need setting up site 2 site VPN in similar setup?

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.

I've setup a site to site vpn on an ASA 5510 using ASDM (as I have many times before) and the tunnel appears to be up but I am not able to pass traffic. When I run the packet tracer from my inside network to the remote destination network, it shows that it is blocked by the implicit deny ip any any rule on my inside incoming access list.

we 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?
Here is my NAT config:
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static VPN_Network VPN_Network no-proxy-arp route-lookup
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static DOMAIN_REMOTE DOMAIN_REMOTE no-proxy-arp route-lookup
!
object network DMZ_Network
nat (DMZ,Outside) dynamic interface
object network DOMAIN_LOCAL
