Cisco VPN :: 5505 - Site To Site ASA / One Subnet Only Working 1 Way
Nov 23, 2011
I have a 5505 connected to 5510 via a site to site VPN, the vpn has 5 subnets on the acl list at both ends, but 2 of the subnets are assigned for remote access on the main 5510, which means the flow of traffic on these 2 subnets are main to remote, but the VPN only works if the traffic starts from remote to main.
both sides are set to bidirectional and I'm not sure if this is the case for all 5 subnets has remote site always sends data to the other 3 subnets first.

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 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 network of 5 different ASA 5505 they are all connected via site to site VPNs. 4 of the routers are working fine but the 5th one is only connecting to 2 VPNs when it should be connecting to 4 VPNs. I have verified that all the settings are correct on the routers (peer ip address, PSK, etc...) but the router still only connects to 2 VPNs. Is this a licensing issue? The license of the router in question looks like this: [code]

I'm experiencing troubles in setting up a simple site-to-site VPN between two new ASA 5505. I tried several times with the ASDM tool entering configuration manually or using the wizard, resetting every time to factory defaults, but the tunnel wont work.

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 a cisco ASA 5510 at the branch here. It terminates about 8 vpn tunnels and also it supports remote access clients. I just have a quick question. Can my remote sub-net group access the other remote access site-site VPN subnet group. If yes then how should i configure it.

I have some VPN site to site ( site B and site C connect to site A ). This subnet 10.0.56.0/28 is behind site B. Another subnet 10.0.56.16/28 is behind site C. I would like to route this 10.0.56.0/28 to reach the subnet 10.0.56.16/28. Is there any possibility to do this on ASA5520 (site A)?

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).

here is my setup:
ASA 5505 - 192.168.3.1
PIX 501 - 192.168.1.1
PIX 501 - 192.168.1.2
The ASA and the first pix device (192.168.1.1) are connected via site-to-site VPN on the ASA side and the connection works great. I can access hosts in either direction from either network.I'm attempting to add the second pix device to the ASA's site-to-site configuration, but it's not working. I suspect it's because the devices are on the same subnet, but I'm hoing to find a workaround.When I have both PIX devices setup for site-to-site on the ASA, the VPN works only for the connection that has the highest priority. The device with the lower priority can only ping the 192.168.3.1 network, but full network connections fail.Is it possible to do this without changing the subnet on the second PIX?

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 ?

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!

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
no service pad

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 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 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.

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.
As it will look like

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

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

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.

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 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?
