Cisco VPN :: Separate L2L VPN Tunnels On Multiple External ISP Interfaces With ASA 5510
Oct 18, 2012
Due to special circumstances we have 2 ISP links on an ASA5510. I am trying to terminate some L2L VPN tunnels on one link and others on the second ISP Link, eg below:
LOCAL FIREWALL
crypto map outside-map_isp1 20 match address VPN_ACL_Acrypto map outside-map_isp1 20 set peer 1.1.1.1crypto map outside-map_isp1 20 set transform-set TS-Generic
crypto map outside-map_isp2 30 match address VPN_ACL_Bcrypto map outside-map_isp2 30 set peer 3.3.3.3crypto map outside-map_isp2 30 set transform-set TS-Generic
crypto map outside-map-isp1 interface ISP_1crypto map outside-map-isp2 interface ISP_2
crypto isakmp enable ISP_1crypto isakmp enable ISP_2
route ISP_1 0.0.0.0 0.0.0.0 1.1.1.254route ISP_2 3.3.3.3 255.255.255.255 2.2.2.254
Establising the VPN tunnels in either direction when using ISP_1 works fine establishing in either direction from remote access users and multiple L2L tunnels (only showing one for example).
On ISP_2
1. Peer 3.3.3.3 device establishes a VPN tunnel, but the return traffic does NOT get back to devices on 3.3.3.3 tunnel.
2. The local firewall does NOT establish a VPN tunnel going to 3.3.3.3
It would seem to indicate that the problems lies with this multihomed firewall not directing the traffic correctly to either return down and establised VPN tunnel (point1) or to intiate a tunnel if none exists (point 2).
Reconfiguring the VPN tunnel peer for 3.3.3.3 to be on ISP_1 of the local firewall, all springs into life! There are sufficient license etc...
I have ASA5510 with PLUSE License.I have 2 Inside interfaces as STAFF and MAIL and two Outside interface OUT_STAFF and OUT_MAIL which is in separate ISP's.now i want to nat STAFF to OUT_STAFF and MAIL to OUT_MAILbecause I'm having two default routes it gets impossible to do.
I am trying to enable a second WAN interface on our ASA.the end goal is to move all internet traffic to the new connection, but first i want to test it working.I have setup my computer as an object in the ASDM and the interface is configured correctly (same settings on a different router and that was working)I setup a route with a lower metric ( 1 lower than the default route which routes everything through current main internet interface) to route traffic from my computer out through the new interface but i am still connected on the old interface.I duplicated some of th NAT rules (but i would have thought if these werent working then i would have no internet connection anyway)
I am working on replacing our Checkpoint Firewalls with ASA's, and am running into the following NAT problem. On some of our Checkpoints, there are external NAT's that are mapped to multiple internal hosts based on ports.Is there any way to translate that to the ASA? I'm not sure the ASA will let you have multiple internal hosts mapped to one external IP using static NATs. The main issue, is these are alarm panels that receive data from external hosts (the traffic is initiated externally on the Internet) so I can't use dynamic PAT with this.
I am trying to build a new network from scratch, I have the WLC 5508 w/ Aironet 3600e APs connected to my Netgear Smart Switches and a Linksys RV082 router that I'm using as my DHCP server with several VLANs for several stuff on my Switches.
I have 2 questions:
1. Can I have 5 Interfaces configured on 5 different VLANs, each SSID on each a different Port:
Port 1: Controller management only=> 192.168.x.x /24 Port 2: SSID 1: WiFi Internal=> 172.16.x.x/12 (Radius Auth with no sharing) Port 3: SSID 2: WiFi Internal w/ sharing=> 192.168.x.x/24 (Radius Auth with sharing) Port 4 :SSID 3: WiFi Guest=> 10.0.x.x/8 (Web Auth) Port 5: SSID 4: WiFi IT=> 192.168.x.x/24 ( Radius or certificate Auth with access to the controller management interface)
2. How can I use the Controller as the DHCP server for all the WiFi traffic, and how should that be configured to work with my other DHCP server?
I have a 2811 Router with two fast ethernet wic cards installed. I need traffic to go out one interface, but it's received back through another. Both interfaces have public IP's and the same subnet, and are connected directly to satellite modems. One can receive data / the other only send.
Our bank is required to do disaster recovery testing. We are doing this offsite at one of our director's businesses. His setup is as follows: His ISP is Time Warner which provided him with a wall unit and a switch He has a Cisco 1841 router out from the Time Warner switch and then down to his internal network, so TW wall unit --> TW switch --> Cisco 1841 --> internal network.The IPs provided to them from TW are 74.219.xxx.1-254 We are trying to use the external address of 74.219.xxx.222, which his business is not currently using internally The Cisco 1841 router holds and NATs all of these addresses currently. We have a Cisco 800 series that is a dedicated router that needs an unused external static IP setup separate from their network. We were trying to plug into their Cisco 1841 and give the 800 series an internal address of 192.168.xxx.222. This will not work for our bank's core processing data center. It has to be out of the TW switch and have an address of the 74.219.xxx.222.
We tried plugging into the TW switch and making the 800 series router parallel to the 1841 router. Communication is not functioning when set up this way. This was tried on a laptop before using the 800 series router. Is there a way to pass through the 74.219.xxx.222 address internally through the Cisco 1841 so we can connect the 800 series directly to this address and the 1841 doesn't use or NAT it in any way?
We had contacted TW support and they made it sound like we would have to block out some addresses and resubnet our director's network. This probably will not be an option. Basically we need to pass the 74.219.xxx.222 addresses internally and have the Cisco 1841 pretend not to see it at all.So we would like to have 74.219.xxx.1-254 into the TW wall unit --> TW switch --> Cisco 1841 --> all 74. addresses resolved to 192.168.xxx.1-254 to internal EXCEPT 74.219.xxx.222 which would pass through to the Cisco 800 series router.
I have got a 1TB external HDD...I want to use this to backup my data (dokuments , pics , video) that are on 2 desktops and one laptop---
AS I understand the terminology a I won't have enough room to do image backups (these back up all info incl OS ??) as on pc is usingb 677 gb and the other 400 gb ---- and anyway I can re-install windows if anything goes wrong...
SO---am I able to do this-
1. connect the ext- HDD to PC running win 7 64 bit....create a folder called "win 7 64 bit" and then drag and drop filesand folders into that folder(or use windows backup..which i am unfamilar with)
2. then connect to PC running Vista 64 bit ..create a f�lder called "Vista 64 bit" and do as above....
3. Do the same for the laptop running win 7 32 bit
Am I right in assumming that because it's just data I can put info from different OS on to it without and conflicts when connecting it to different Pc's?
I have a question about external antennas on an access point. I have to plan a wireles solution, that also includes coverage in the industrial freezers. The freezers are one part of the sotck rooms, so the general coverage will be done with 1602I access points.
Since there are quite a lot of freezers in one location, installing separate AP in every freezer will be very expensive. I wondered if there is a possibility to put one 1602 access point with external antennas outside the freezer and then extend the antennas with 2m cables inside different freezers (1602E has three external antennas, so one antenna to each freezer).
Would this installation even work?
The freezers are quite small rooms maybe 2-3m2 sow the coverage is not a problem. But does this installation support multiple clients per AP in different freezers doing stocktaking with handheld terminals?
I am a employed at a credit union with 17 branches. We have a mpls circuit connecting the branches to our main office. I setup DSL as a backup connection. I have 17 RV042 Cisco VPN Routers. I created a secure vpn tunnel for every branch to the main office. I made a delayed route in our main router to fail over to the VPN, in case the mpls failed. Almost everything works great except our ATM's are required to connect to a router at our main office to a different subnet than the tunnel is connecting, therefore not routing through the tunnel. I've tried creating another tunnel but only works with one of the branches, cause I get a conflict at the main office when I try a second tunnel with the same ip network. Also I tried routing all the traffic through the vpn by putting in the address 0.0.0.0 subnet 0.0.0.0, at the branch site. But I can only do that for one branch, The Downtown Cisco won’t let me create another tunnel with that setting.
We have 2 Cisco ASA 5520 configured as Active/Standby with public IPs 68.171.xxx.xx6 and 68.171.xxx.xx7 respectively.We have 3 different vendors who are trying to access our Data Center. Do I have to have 3 different public IPs for these 3 different vendors? Or, just share the public IPs assigned to our 'Outside' interface?
i am building new vpn tunnels for multple sites using 2 ASR 1004, and 100 remote devices cisco 2800 routers.I am thinking of using getvpn to do it, am i thinking correct ? can i use DMVPN
I purchased the RV180 to replace a dead Linksys BEFVP41 to connect a home office to HQ. The Linksys was configured with three IPSEC tunnels to connect to three different subnets all through the main HQ gateway. Note that each tunnel is independent with its own pre-shared key. I can configure the same tunnels on the RV180, and each one works correctly, but I can only get one to run at a time. I have to disable the other two. Enabling a second tunnel results in the No phase2 handle found error. I could not use the Basic VPN setup as it complains that the remote endpoint is already in use. I had to use the Advanced VPN Setup to create the IKE and IPSEC policies. In a different discussion [URL]
I am using a 6500 with FWSM. I need to separate an internal server/HQ network from 3 or 4 different external connections. The external networks do not necessarily need to be isolated from each other.I have the option of using a 3 layer model: L2 Access layer to SVIs on the Distribution layer and then L3 to the 6500.L2 Access, connecting directly to the 6500s, with the SVIs on the FWSM.Is it better to have the FWSM outside the MSFC or Inside? Am i correct in thinking that "inside" vs "outside" is determined by whether the SVI's are configured on the FWSM or the MSFC? is there any performance impact from having the FWSM doing the routing instead of the MSFC.If the vlans are all configured on the FWSM, what is the 6500 doing, other than providing switch ports?
I'm trying to research the tunnel limits on a 5508 controller if you're terminating controllers to two different SSID's. For example. In my DMZ i have a GUEST SSID for contractors and guests and then I have another SSID used by employees so that tablet and mobile phone users can access the interenet. Because we don't trust any of these devices we have that SSID is termiated just as we do our GUEST SSID.
To reduce the number of anchor controllers I deploy, I wanted to start with one 5508 Controller. (then move up to about 3) This controller would have two SSID's, GUEST & MOBILE. On the Foreign controllers when I setup anchor tunneling I will be anchoring to the same controller however to two different SSID's.
Per the 5508 specs it supports 71 tunnels.
So my question to the group is, will the 5508 see this anchoring as one tunnel each? Or does it support 71 Tunnels per SSID?
We have several remote sites with Linksys WRVS4400N and Smoothwall firewall/vpn devices. I need these sites to be able to connect to multiple dis-contiguous subnets at our main office. This was easily done with smoothwall and linksys. You create a separate tunnel for each subnet and voila, you're done. However, when I tried this with our newly installed ASA, it will not let me create multiple tunnels to the same remote peer address. This is a problem since these sites only have a single static public IP address. Am i missing something or does the ASA not allow connections to/from multiple subnets form a site with a single peer address?
Has come across issues with multiple GRE tunnels between two devices when using the same source and destination addresses. I've tried using tunnel keys but this makes no difference. The only way I can get this to work is between different source & destination addresses.
I need to create multiple ip-sec vpn tunnels on A Cisco 837 ADSL Router. I am able to create one tunnel but the second connection is asking for the outside interface which is atm and already taken by the first tunnel. How can i create more tunnels?
Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?
I'm trying to monitor Tunnels activity. We want to gather statistics like bandwidth utilization per Tunnel and in the case of Remote Access also the user name associated with a tunnel. All this via SNMP
I've browse through the Cisco-IPSec-Flow MIB and found the TunnelTable, this seems to provide everything I need in Regards to Tunnels, I just need a tip in how to calculate or obtain the bytes Tx and Rx. I can obtain packets and Octets amounts but not actual bytes. Is there another OID I should be inquiring?
In regard to Remote Access I found the CRASSessionTable From here I can obtain the Group associated with the tunnel and I should be able to obtain the User name through the 1.3.6.1.4.1.9.9.392.1.3.21.1.1 OID, but I'm getting an UnSupported response when querying this particular OID.
What OID can provide the User name?
I know that Cisco Performance Monitor can in fact obtain all that info from the ASA so there must be an appropriate OID I can query to obtain this particular info.
I have an ASA 5510 running ver 8.0(2) that has (4) Ipsec tunnels going from it to various other locations. I am having an issue with data transfer speed on only one of the Tunnels. This tunnel is between the 5510 and the 5555, on that link I am getting a dat transfer rate of a little over 120k a second, whereas if I pull the same set of files from another location I am seeing a transfer rate of 5m per second.
I have verified that it is not a capacity issue on the Internet bandwidth on both locations, and I can pull the same data from the same location to various other locations via Ipsec tunnels, I am only having an issue with a specific tunnel going from the 5510 to the 5555.
Since it is not affecting other tunnels on the 5510 nor is it affecting tunnels on the 5555 going to other locations, I am leaning toward a routing issue within the ISP? I will say the ISP is taking me a long way around to stay in the same Metropolitan area.
I have an ASA 5510 at Site A with a L2L tunnel to another site, Site B. Single subnet at each site. In a few weeks we will be adding a second Internet connection to Site B, so both connections will be active. But we want traffic to go over the new connection unless it goes down, then use the other. How do I set that up on the ASA so it doesn't get confused as to which tunnel to take to get to the Site B subnet?
I have a trouble with 2 IPSec tunnels on Cisco ASA 5510.Both of them are Site-to-Site tunnels.Both of them are established against the same public IP address on my site.It looks like they cannot run steadily in the same time. It looks like when one of them is actived, the other one could not be up.Is it some kind of limit of Cisco ASA?
I have an ASA 5505 with the security plus software and I'm trying to find out how to assign 2 public IPs to the outside interface and have each IP routed to a separate internal VLAN. For example, IP 1 = X.X.X.1 routed to 192.168.1.0 and IP 2 X.X.X.2 routed to 192.168.2.0. I was told this was possible and I've been trying to find configuration examples, but I can't seem to get anywhere and now I'm getting desperate because I'm scheduled to install it this weekend.
I have an ASA connected to 2 ISPs.I am using object tracking for the default route so only 1 path is used at a time. I have a L2L VPN setup going out interface A. I would like to configure a 2nd VPN going out interface B with identical parameters.

I tried to monitor via SNMP my ASA 5550&5510 my Active IPSEC tunnels , I want to receive Bandwidth for each tunnel interface.I’m running Version 8.2(1)? which OID to use?
If I have a PI 1.2 system that has multiple interfaces configured I can upgrade to PI 1.3 and both interfaces remain and I can see both under the admin webpage under appliance interfaces. But if I do a fresh install of PI 1.3 I can only configure one interface. The commands fail from the cli to configure anything but gigabitethernet 0. Are multiple interfaces not supported in PI?
Having upgraded to 8.3 from 8.2 I and read much about the differences , it seems that 8.3 deals with NAT in a much more managed method.However I am confused on how one would NAT a network object to multiple interfaces? i.e I know you can specficy a NAT adddress within the network object howeveer this only allows you to specific a single IP address.What if I want to talk accross multiple interfaces how would I specify this?
is it possible to have the ASA connected to two ISP's and use the one ISP connection for Client/S2S VPN and Internet Access and the second ISP connection just for the WebVPN Traffic? How would you manage the Routing, as the default route is pointing to the first connection or is that not an issue here?
We have an ASA 5510 firewall. There are 4 ports on it configured as 2 outside, one inside, and one DMZ. We have two cable modems attached to the outside ports. Our plan is to have the "inside" port directed to one outside port/cable modem, and the DMZ port directed to the other outside port/cable modem.
We have been able to get the "inside-to-outside" setup to work but not the "DMZ-to-outside" setup (at least at the same time).First off, is this possible? If so, what are we likely missing - some way to have a second default route for the DMZ?(My manager is the "Cisco person" here, not me, so I may not have enough info.
I am trying not to run before i can walk,.. so first thing I'm trying to do is ping out to a DNS server in the internet: 212.135.1.36 from my internal network.
- If I put a default gateway on my router, and set to 172.16.32.254 (Firewall Vlan100 interface) and ping,.. it works fine from my router. - If put a default gateway on my switch below the router as 172.16.32.252 (VLAN100 interface of the router) and ping from the switch it doesnt work.
I assume its getting to the switch as I can ping the 172.16.32.252 from the switch so the router is dropping the packets... my question is why!?
Once this bit works,.. the intention is to route any external bound traffic that comes from VLAN100 to 172.16.32.254, external bound traffice from VLAN200 to 172.16.64.254 etc etc
