Cisco WAN :: AES-128 IPSEC Site-to-Site VPN Multiple Crypto Maps For One Peer
Jan 28, 2013
With à customer we have à site to site VPN connection. In this tunnel there is one subnet routed with a 3des-sha encryption / hash. Now the want to add a new subnet in this tunnel, but with a AES-128 / MD5 encryption / hash. Is it correct if we make a new crypto map with a higher seq. number?
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.
The scenario where a Site to Site VPN tunnel has been established between Site A and Site B. Lan on Site A can ping Lan on Site B. My problem is a Printer behind Site B needs to be accessed by using the WAN IP address of Site A. Also i could not ping the remote lan or printer from the router.
Below are my configure on the Cisco 877 in site A.

I have a Cisco C837 router all functional with client access VPNs setup and working, its a inherited setup and not our own and i need to create a site to site VPN to another Cisco small business router preferably whilst keeping the current client access setup, from what ive read you can only have 1 crypto map per interface and i can just about get my head around creating a static VPN for site to site when the router doesn't have a existing crypto map and policy, i cant however figure out how to add the site to site on top of this setup and from what i have read it can be done using the existing crypto map but im only getting bit of the required setup information from here and there nothing concrete.
I have a ASA 5510 actve/standby and create one site to site VPN with remote peer ip address xx.xx.xx.xx, Our VPN traffic running on 6 mb internet link for video conferancing traffic.Now client give another link 2 mb internet and client told to us our data traffic runnig on 2 mb link but this data traffic running on the same remote peer IP xx.xx.xx.xx.
Secondly request also they need failover over the ISP link.
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.
I am trying to set up a site to site ipsec connection. AT site A, I have Vlan's 652-10.55.216.0/24, Vlan653 -10.55.217.0/24, Vlan 654-10.55.217.0/24 and Vlan655-10.55.219.0/24 and at site B, Vlan650-10.55.214.0/24 and Vlan651-10.55.215.0/24.The problem is that I am unable to get any associations when i do a "sh crypto isakmp sa"/"sh crypto ipsec sa" on either router at each site.I am also unable to ping by pluging in a laptop into the site at each site. Laptop at site A is set to access vlan 655 and laptop at site B is set to acess vlan 651. I can ping all the devices from one end to the other.I have turned on debug crypto isakmp, debug crypto ipsec, debug crypto ipsec errors but dont get anything at all as output.I have attached the sh run for each router Cisco (1941/K9) and switch (Catalyst 3750) at each site.
I have an ASA 5525 and need to configure site to site ipsec vpn to 3 peers. I currently have an existing /28 public address from my ISP that is used by other services.Is there a way to use this existing ip range to configure IPSEC tunnels to 3 peers ?
I have two Cisco routers - 2911 in HQ and RV180 in branch office. Because in HQ LAN network I have some development servers, to which guys from branch office need to have acces, I decided to setup VPN site-to-site between HQ and branch office. Everything went quite smoothly, on both devices I see, that ipsec connection is established. Unfortunately I am not able to ping resources from one network to other one and vice versa. Below is the configuration of 2911 router (I skipped som unimportant (imho) configuration directives) :
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.
We have a scenario where the Cisco ASA 5505 will be one end of a site-to-site VPN. The same ASA 5505 also allows Client VPN connection. The question is around IP pooling. If I assign a pool of IP's (192.168.1.20 - 192.168.1.30) for Client VPN connections - do I need to be sure that those same IP's are not used on the other side of site-to-site VPN ?
There could be PC's/Servers running 192.168.1.0/24 on the other side of site-to-site VPN. Would this cause an address conflict ?
I have configured Ipsec vpn tunnel beetween two routers (from site A to site B) over untrusted internet connection by cisco 3825 routers and i can successfully access both of this routers. But now i need to access internet on site B router sitting on site A router. So that if i run traceroute from A site machine then the gateway by which internet passing through shows the ip of site B.
The Architecture of our both site routers :
Site A 10.1.11.0-----Router A 172.18.12.1-----VPN tunnel----Router B 172.18.12.2-----Site B 10.4.11.0

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.
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 situation where the site-to-site tunnel is already established using PPTP IPSec VPN with non Cisco Gateways terminating the link on each end. These non Cisco Gateways do not support L2TP tunneling, and there is no plan to change them.Beyond the Gateways on both ends, we have a Cisco 4500 series switch. We need to forward the 802.1q tagged VLANs between the two sites. Is it possible to use 802.1Q tunneling in this case, going via a PPTP tunnel ?
Cisco's setup uses dot1q-tunnel over a L2protocol-tunnel to preserve the original client VLAN tagging, so does this mean that the only option we have is to setup a L2TP tunnel at the Cisco device endpoints, and have that tunnel go through the existing PPTP tunnel (established between the 2 non Cisco VPN Gateways) ?
My requirment is Clients from site A should access the Internet from site B (B will be providing internet to site A), So I have configured Ipsec vpn tunnel beetween two routers (from site A to site B) over untrusted internet connection by cisco 3825 routers and i can successfully access both of this routers.I have configured a client machine in site A and configured gateway of this client is 10.1.11.254 but dont have internet there.
I have a Cisco 2911 router and a Cisco RV 120W router and i would like to establish a VPN tunnel between theese two. I have defined the settings on the Cisco RV 120W router and i just want the Cisco 2911 to follow those. setting up a connection with Cisco IOS.
Site A has an ASA 5510 and a single internet connection.Site B has two internet connections (primary and backup). If Site B also has an ASA, I can configure Site A's ASA to deal with a failover at Site B (set peer 220.127.116.11 18.104.22.168). Does this work if Site B has an IOS router instead of an ASA? In other words will "set peer 22.214.171.124 126.96.36.199" on the ASA work when it's talking to IOS on the other end?
I am having issues getting my ASA 5540 at site A, to pass TFTP and SYSLOG from itself across the IPSEC tunnel to our SYSMON servers (Syslog and TFTP) that live at site B. I have followed the suggestions of other threads and I am still not getting anywhere. Here is a quick topology diagram.
I have cisco pix connected at the edge of my GPRS network. Inside is the GPRS core network and outside is the ISP.On cisco pix, i have site to site IPSec configured between my inside GPRS network and Blackberry servers. for blackberry services.Using the ASDM I can see the total number of packets in and out on this site to site IPSec, but if I want to measure the trand of the bandwidth utilisation over this IPSec, per sec, then how can I do this? I have PRTG traffic monitoring, through which I did try, several MIB (listed below) but still not able to find the correct way. how can I get the measurement for the IPSec from cisco pix?
I cannot get it to work : if interesting traffic comes ffrom the IPSO side, the box would not even try to set up the tunnel. and If it comes fomr the ASA side, the box attempts to do so but it with this strange message : AM_WAIT_MSG2
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) ?
currently I have a Cisco 2921 router and I have one active site-to-site VPN connection through the internet.my question is; how I can create another Ipsec site-to-site VPN connection ? I have to keep the 1st VPN connection active.
you can configure a cisco 1905 router with vpn ipsec site-to-site in an aggressive mode? If so, any link to what I do? The VPN works well, but on site A, I had to configure a crypto map associating the IP address for site B (wich is dynamic), so if the connection on site B broken, I will have to configure another crypto map.
The scenario is:
Site A - ASA 5510 configured as a VPN concentrator and firewall for enterprise.
Site B - Cisco 1905 connected to Internet through a ADSL through a dynamic IP address and starting connection to Site A, bellow is the configuration:
I have a very basic lab site to site vpn setup where I have a ASA 5505 running v7.2(4) on one side and a cisco 2811 on the other side.
What's my issue?
I can't seem to ping from cisco router to the 'inside' network of ASA (see config below) and can't seem to ping from ASA packets leaving the 'inside' interface to cisco router even w/ an ICMP ACL permit outside in. However I'm able to ping within ASA inside network & ping cisco 2811 side w/ packets leaving ASA 'outside' interface just fine.
example: ------- ciscoasa# ping inside 10.20.20.1 (to cisco loopback1 from ASA inside) Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.20.20.1, timeout is 2 seconds: [Code].....
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'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.
[code] Site-to-site VPNs in place between Site A and Site B and between each site to the DC. Site A and Site B have Cisco 2911 routers, there are ASA’s at the DC. The existing Site-to-site VPNs carry data and voice traffic between the sites (though voice and data is on separate VLANs in separate subnets)
ISP1 currently used for the existing circuits at Sites A and B but we have experienced issues with them recently which has disrupted service. So new circuits are to be installed at each site with ISP2. (See basic diagram attached which shows current set-up with intention to get new circuits via ISP2 installed)
We have 3 ports on our Cisco 2911 routers with 2 ports already in use for the existing connections (1 for the LAN and 1 for the WAN connection to ISP1) Can we simply use the 3rd port for the connection to ISP2 or would it be far more advisable to use a 2nd router (for redundancy, etc)
Would it be feasible to have a set-up where we have e.g. voice traffic go over a site-to-site VPN via ISP1 and data traffic go via site-to-site VPN via ISP2 but each can take over from the other in the event of a failure?
I've spent 2 days already trying to get 2 ASA 5505's to connect using an IPSec vpn tunnel. I cannot seem to figure out what im doing wrong, im using 192.168.97.0 and 192.168.100.0 as my internal networks that i'm trying to connect over a directly connected link on the outside interfaces with 188.8.131.52 and 184.108.40.206 as the addresses (all /24). I also tried with and currently without NAT enabled. Here are the configs for both ASA's, the vpn config was done by the ASDM, however i have also tried the command line apporach with no success. I have followed various guides to the letter online, starting from an empty config and from factory default. I have also tried the 8.4 IOS. [code]
