Cisco Firewall :: Max Number Of Clients And Site To Site VPN Tunnels On ASA 5505
Aug 15, 2012
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

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.
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 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
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 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 no service pad
I've set up a standard site-to-site VPN between 2 ASA 5505s and the VPN is working fine for traffic between these ASAs and computers which are in the same LANs.but when I'm trying to connect to computers which are in another VLAN I have a problem.
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 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?
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?
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 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.
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.
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 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 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'm trying to establish a vpn tunnel with a sonic firewall. We've checked both ends for differences and they are the same. PFS has been disabled on both ends. I'm seeing this in the logs.

cisco products and am struggling getting a VPN going between an ASA 5505 and 5510. I have a VPN created (using the VPN wizward on both) and it shows the VPN is up, but I can't ping the remote site (from either side).
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
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.
i have 2 router asa 5505 with base license i wanna make site to site vpn connection and remote site using vpn client to connect first i have hdsl router with 5 public ip i wanna try it by giving 1 public ip to each router and try the vpn but nothing work?
I have an ASA 5510 8.2(5) in Site1 and a ASA 5505 8.2(1) Site2 they are setup with a site to site tunnel.Each site has VPN clients that connect and I would like to allow clients from both sides access to servers on the other side of the site-to-site tunnel.
I enabled same-security-traffic permit intra-interface I also added the remote networks to access-list that is doing the split tunneling. [code]
I have a situation where I need to have remote users vpn into my ASA 5510 and then turn around and hit a site to site tunnel. Now when I am in our office I can hit the site to site vpn fine. When I am at home and vpn to the asa I can not get to the site to site resources. Do you see where my config is incorrect? result of the command: "show run"
We've just deployed a site-to-site VPN using a 5505 ASA on the client's site and a checkpoint Nokia FW on our site. Everything seems to be fine except that the user's connections to their file shares seem to be intermittently dropping. One minute the connection to the shares is there, next thing it's lost. There is no logic to it because no two users are experiencing issues at the same time, as a matter of fact even on the same PC where a user has access to 3 shares on 3 different servers, one could be showing as connected whereas the other two be dropping. [code]
As you can see the Duplex and Speed are set to auto, I've rectified this since then and I'm keeping a close eye on the output errors, and collisions. However, I'm afraid that this did not rectify the issue and the users are still experiencing intermittent connection dropping to their file shares over the VPN!
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.
im drawing a blank trying to setup a site to site connection with a 5505 ASA using ipsec and isakmp.i have the pre shared key as well as the external address of the other end of the tunnel but do not remember what the commands are to setup the crypto map and isakmp.
I have tried Cisco presales but got bounced - go Cisco !So, i have a small customer who requires a single device which will provide .....
1/ Leased Line connection @ 10mb 2/ ADSL failover onbox (so configurable from CLI, unlike the 860’s which I see only have one ‘active’ wan port) 3/ IOS based 4/ integrated 4 ports (min) switch 5/ site to site VPN 6/ up to 10 x SSLVPN remote users
I did pitch in with ASA5505 with external ADSL router but he is “space-constrained”.It worries me when Cisco doc's say only one WAN port is 'active' - since it doesn't say the second port automatically comes up if the first goes down so I can't take a gamble on that being the case.
I have an ASA5505 running which is on a static IP. I have just got an SRP527W for a remote worker and want to create a site-to-site VPN into the ASA. I have a number of other router of non-cisco brand which just all dial-in and connect no problem.
On other routers I have been abloe to specify the DDNS hostname in the VPN setup so that the ASA can identify it. I'm not sure how I setup the SRP527 to connect to the ASA.
