Cisco VPN :: ASA 5505 / Dynamic-to-Static Site To Site VPN?
Nov 7, 2012
I have some sites already connected with ASA 5505 site to site VPN with both end static IP. Normally, all traffic can come across without any problem. Even I used "management-access inside" for both ASA.Now I have a new office with only ADSL pppoe connection. I used easy VPN to connect from Site B:remote dynamic IP site to SiteA:static IP with similar example of this: [URL]
All my 5505 ASA are running 8.4(4)1
Site A - Static IP
Site B - dynamic IP with pppoe connection.
After EasyVPN connected, i do not know how do I remote manangment from site A lan to site B 5505 ASA?

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 am having a heck of a time configuring 2 RV180W's to establish an IPSEC VPN tunnel. I have some experience at this with other Cisco products (RV042/082) but I can't get these beasties to cooperate.One RV180W is at a client's office and there are to be 1x RV180W and 1x RV120W located at 2 employee's residences.The office has a Static IP and the homes have dymamic IP.I figured I would config the units in the homes to be initators and connect to the office where the static IP is. This is failing for me so far. Any example (screenshot?) of a config where this is working? The firmware on the RV180W's I am trying to configure first are current.I even tried testing from my office (where I have multiple static IPs available) from RV180W here to RV180W at client's office (static at both ends) and I can't get a tunnel to come up. Obviously I am missing the boat at some point in the setup.

I am using a Cisco ASA 5505 Here is a description of my topology.
Headquarters = 192.168.201.0
Client X = 172.16.0.0
Datacenter = 10.12.0.0
Site to Site Tunnels:
Headquarters ---> Datacenter
Datacenter ---> Client X
I want to ability for computers in the Headquarters subnet to access the Client X subnet.I have tried setting up a static route to push all traffic destin for 172.16.0.0 to the datacenter, but was unsuccessful. how I can route all 172.16.0.0 through the tunnel.I have tried ading a static route on my ASA but without success.

I need to set up a site to site vpn between 2 ASA (1 5510 and a 5505). The 5505 internal network is also in use on the internal portion of the 5510 so I wanted to NAT the outbound traffic from Site A (5510) to Site B (5505) and vice versa. I was thinking of doing something along these lines:To allow the traffic to flow through the tunnel when having the same addressing scheme on both ends, you should NAT the VPN traffic. [code] And then I would use the "crypto" acl for building the crypto map.

I'm trying to figure out how to get two 5510 ASA's to establish a Site-to-Site VPN.The version with two static IP's is working perfectly and stable but I haven't figured out how to get a VPN running between a static and a dynamic IP

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 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 want to connect two sites through a VPN tunnel, such that each machine can access all others, regardless of which site they're located.
The two sites have a VDSL connexion with dynamic public IP addresses. Unfortunately, our ISP does not offer static IP addresses with VDSL connexions.
I plan to do the following : install two RV 120W routers, one at each site, right after the VDSL modemconfigure the modems in bridge mode, such that the 120Ws get directly the WAN IP address and trafficuse DynDNS to assign domain names (site1.dyndns.org and site2.dyndns.org) to each siteassign different subnets to each site (ie 192.168.1/24 for site 1 and 192.168.2/24 for site 2)configure a VPN tunnel in gateway mode using the FQDN (site.dyndsn.org and site2.dyndns.org) of each site on both routers, with corresponding remote subnets

I have Cisco 877 routers, with ethernet (LAN) and ADSL (external) interfaces. The ADSL interface gets dynamic IP. Is Site to Site VPN with Dynamic IP and Internet Browsing Possible on the Same Router.

I recently bought two RV042s to create a site to site VPN for a client. I have several of these setups installed at other locations but this is the first version 3 hardware I've used.It seems like the dynamic IP functionality of the VPN setup may not be working correctly. I've verified all settings on each router match and have deleted/recreated the setup several times just to make sure. Here's the logs from the router with a static IP.
Nov 29 06:49:51 2012 VPN Log (g2gips0): deleting connection
Nov 29 06:49:51 2012 VPN Log added connection description (g2gips0)
Nov 29 06:49:51 2012 VPN Log listening for IKE messages
Nov 29 06:49:51 2012 VPN Log forgetting secrets
Nov 29 06:49:51 2012 VPN Log loading secrets from '/etc/ipsec.d/ipsec.secrets'
Nov 29 06:49:51 2012 VPN Log (g2gips0): cannot initiate connection without knowing peer IP address
Nov 29 06:49:51 2012 VPN Log (g2gips0): cannot initiate connection without knowing peer IP address
I've tried both dynamic IP + email and dynamic IP + FQDN to authenticate the router using the dynamic IP and both give the same error as above.I did a firmware update hoping to fix PPPoE which seemed to be broken with a Netopia modem in bridge mode so both routers are on the latest firmware, v4.2.1.02.

I've got a problem with establishing VPN site-to site tunnel from client (Cisco 1801/871) with dynamic ip addres. My central site using static address but remote site(s) has dynamic IP, and I don't want using dyndns etc. ... just simple any ip client connecting to central site. It had worked very well with Cisco 1812 which was changed for RV220W. Any other tunnels between two static sites works fine with RV220W.

Scenario using ASA V8.4
RemoteLan - Router Dynamic WAN IP ----------- site to site VPN --------------ASA - ASA Lan 192.168.1.0/24
10.1.1.0/24
I am trying to get my head round configuring an ASA with V8.4 code where things have changed especially NAT.In earlier ASA 7/8.x code I belive the crypto map below would have allowed a properly configured remote router to connect irrespective of its WAN IP
I am struggling to get my head round how I achieve the same in ASA V8.4 . I have searched the web and found plenty of examples for earlier code but specificlly am trying to learn about how to achieve it with v8.4
access-list outside_cryptomap_20.1 extended permit ip 192.168.1.0 255.255.255.0 10.1.1.0 255.255.255.0

I am trying to set up a Site to Site between two RV042 with static IP at both routers.at the log at site 1 i get: packet from XX.XXX.XX.167:5: initial Main Mode message received on 10.2.32.1:500 but no connection has been authorized with policy=PSK.At site 2 i get: packet from xxx.xxx.xxx.146:500: initial Main Mode message received on 192.168.1.1:500 but no connection has been authorized with policy=PSK.I have tuned off the firewall and added a Port forwarding to the router ip and port 500.Tried with different autentication methods, but get the same message.

I'm trying to set up a site to site VPN link between the ASA5510 that we use exclusively as a VPN endpoint on campus and a D-Link DIR130 VPN Router off campus, at a local business with a dynamically assigned IP. We currently use the ASA for remote access users who use the Cisco VPN client on mobile devices, as well as for a single site to site link to our telecom provider for the purposes of monitoring telecom equipment remotely.We are looking for a way to cheaply deploy secure VPN connections to local businesses to allow them to use point of sale devices which connect back to systems on campus, so students can use their meal cards at local restaurants, similarly to how they use them at the on-campus cafeteria.
I have experience configuring Cisco switches, APs and routers, but this ASA device absolutely baffles me. I've futzed around with the ASDM 6.4 gui config and tried to match up configurations between the DIR130 and the ASA, but I can never get a VPN connection to come 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 ?

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

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.

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.
