Cisco VPN :: WRVS4400N - ASA Cannot Create Multiple Tunnels To Same Peer Address?
Jun 23, 2012
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?

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 find a reference for how many IPSEC tunnels the WRVS4400N can passthrough.

I have an ASR 1002. Behind that and across another small MAN network (considered inside) I have an ASA. On the remote end, I have a simple 2811.
I need to create a vpn peer from the remote router to both the ASR (to hand off traffic there) and also a peer at the ASA (to encrypto across the MAN). The ASR1002 has the serial connection (DS3) to our MPLS cloud in which the remote is on the opposite side of.
So basically, I've created a single isakmp policy with two crypto map's by the same name but set to different peers and placed on the remote router then applied it to the serial interface. This works fine. Now i throw in the ASA which is behind the ASR. However, the connection still comes through that ASR to get to the ASA.After setting it up, it works as long as I don't have the crypto map applied to the ASR. If i apply the crypto map to the so interface of the ASR, my asa vpn connection stops working.It almost seems as if the crypto map on the ASR is grabbing my enrypted traffic destined for xx.xxx.24.14 and trying to do something with it. [code]
Why can't i peer from my remote router to both the ASA and the ASR on the opposite end of the serial link?

I am currently running a 2821 to terminate vpn links from all our branch offices over a WAN. I need to add a second interface in order to facilitate a move to a different WAN provider. seeing as the 2800 models are EOL I was looking for an upgrade. My local retailer wants to sell me the following:CISCO3925E-SEC/K9 IS Router 3925E security bundle SEC license pack,HWIC-2T 2 port serial WAN card,MEM-3900-1GU2GB Upgrade to 2GB 1,now my question is why can't i use the 2900 models in order to save some money?All I need is a router that will accept 2 different incoming WANs and the ability to create vpn tunnels over them..

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 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'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?

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.

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...

We have an HQ site with a 2811 (w/ADVSECURITYK9-M) acting as the firewall. We currently have 1 ASA5505 that has an established ipsec l2l VPN. I'm trying to connect a 2nd ASA, but I've noticed I can only add 1 cryptomap to the outside interface. A show ver shows 1 Virtual Private Network Module... Surely that doesn't mean only 1 VPN?Do I use one crypto map, and add a second 'set peer' & 'match address' inside the crypto map itself?

Any way of narrowing down a degub for a peer address only? For example, I currently run 'debug crypto isakmp 127' which captures everything, but can I run the same dVPN debug for peer address 1.1.1.1?I know you can run 'sh crypto ipsec sa peer 1.1.1.1'.We're using an ASA5520 (8.4.2).

I've been using an ASA 5505 -- ASA 9.1(1) -- with an IPSec Remote Access VPN. Everything works properly, though I recently noticed that when my IPSec session is disconnected, I get the standard message ID 113019, but within that message the Peer IP address is incorrect. In fact, it isn't even close to my actual remote address. [code]
When I first researched the IP, I found it coming from China, which freaked me out. I changed settings, rolled back to 9.0(1), and nothing worked. Finally I rebooted, reconnected the VPN, and the IP changed. This time it was an address from RIPE NIC. I rebooted again, now an address from ARIN in the USA. One more reboot, now a random Comcast residential address.
Within that boot cycle, the peer address always stays the same. I've connected from different devices, different IPs, different ISPs - nothing matters. Additionally, there are no firewall logs for these IP addresses at all.
ASA Remote Access VPN peer addresses in disconnect message are incorrect and change at reboot.

My current set up is 1 HQ router (2911 ISR) and 8 site offices with a non-Cisco router.Each site has an IPSEC tunnel back to the HQ router.All of the site routers have a dynamic external IP address.This set up has worked ok for now, but I would like to look at moving to GRE tunnels so traffic from the sites can be routed to each over.I have read up on the configuration and I can set up an IPSEC GRE Tunnel in test labs using a static IP address on the spokes however I have not been able to find any documentation on how to configure the HQ router to allow the tunnels from any IP address.I did try setting the tunnel destination to 0.0.0.0 on the HQ side but this does not work.

I bought my WAG320N, I too have the internet drop out and from reading in here is a very common problem. Cisco really should bring out a new firmware version and address this issue. Any way you can block peer to peer file sharing with the WAG320N? If so how do you go about it?

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?

One of the schools whose networks I administer has a peer to peer network running about 30 xp machines. DHCP is achieved and DNS settings distributed via a basic Linksys router; is there any way of distributing proxy server address and port short of entering manually in LAN settings of IE on every terminal - there is no budget to install a server.

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.

Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.
