Cisco VPN :: 5520 Remote Site To Internet Connections
Jan 13, 2012
I have a remote office that currently connects back to a Central data center via Site to Site VPN. I am bringing up a 2nd internet connection as a fall back in the Remote Office. How do I configure the Site to Site VPN to work correctly so that if the primary internet connection goes down, the site fails over to the secondary? On Remote the internet connections are from different providers so they have completely different blocks of public IPs.

We have ordered a pair of Cisco ASA5520 (ASA5520-BUN-K9).Now there is a requirement to terminate site-to-site VPN from remote site. Do we need VPN plus licence for this and how much it cost?

We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ). When Remote vpn users try to connect to computers located on the distant end of site-site VPN, their request failed. I tried No-Nat between remote vpn private IP to the remote site private IP, also stated the same in Split tunneling. I cant find even the tracert, ping also timed out.

I am using asa 5520 and asa 5540 for remote access vpn connections. Is it possible to do active monitoring of my vpn connections so that there would be alerts for vpn tunnels that fail to establish due to other reasons other than user authentication?

We have 2 5520 ASA's working in an active/standby function at our central site. The remote agencies have control of their ASA's or other devices able to create VPN tunnels back to the central site. When a new remote agency wants to connect to our central site we assign them a network range that is routable on the central sites network.We ask that the remote agency NAT into the addresses we provided them.This way we are able to route back to them. We assign the interesting traffic and then they we start communicating by way of the tunnel.
Since the central site can't control the traffic coming in on the site to site tunnel other than just defining the interesting traffic AND we aren't able to control the NAT on the remote end how can I put an access list on the central site ASA to allow only certain ports and IP's by way of access list? Ultimately, I'm trying to limit traffic on the central site coming inbound to only allow traffic I want. I tried applying a group policy to the lan2lan site to site tunnel, but it failed for some reason. It actually prevented all traffic. Can I apply a group policy to a site-to-site tunnel?
I'm struggling here a bit as I don't have control of the remote end. They can NAT whatever they want to an address in the range we assigned them. The tunnels interesting traffic is set to full ip to the central site's destination. The interesting traffic on the central site is set the same. However, on the central side...I want to limit that traffic to only certain ports by way of an acl. If it is possible to assign a site-to-site tunnel a group policy and filtering is done in that method, can

I have a site-to-site VPN configured between a 5520 at our data center, and a 1700 at a client's site for site-to-site connectivity. What I've noticed is, is that the VPN can only initiate from my Data Center, never from the client router. I can telnet into the router and start a telnet session sourced from the "inside" interface and it fails, yet I can see the NAT translations get created in the state table that should match the crypto-map. However, if I ping a host on the inside of the remote LAN from my workstation (behind the 5520) to bring the tunnel up, and run the exact same command on the client router once the tunnel is up, it works. Right now I have a continuous ping running from my workstation to keep the tunnel up, but obviously that's not the best solution
I had to modify this config to NAT the LAN addresses at the client to a non-overlapping subnet, so anything coming from 128.1.0.0/16 should be NAT'd to 192.168.105.[50-200]/24. I've also got two static NATs for inbound access from the data center and those seem to work fine.

I have configured vpn filtering on all my l2l vpns. I have restricted access from remote to local resources only to specified ports. It works perfectly.But I want to have also full access from local to remote networks (but still preserve restricted access from remote to local). As I now VPN Filter works bi-directional with a single ACL. So is there some way to open all traffic from local to remote and still restrict remote to local traffic? ASA 5520 8.4(3)

One of our remote sites want to use our firewall for internet access. We have setup a site-to-site VPN with a default route from the remote site to us. All traffic is routed to our firewall (5520). VPN traffic works perfect. Now the internet does not work for our remote site. Is it possible to route internet over the site-to-site tunnel?

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.

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.

What are the possibilities that exist for running a site to site vpn in our environment with the following infrastructure Cisco ASA 5520 - running on a multiple context mode
-Cisco 3750 switches
-Microsoft TMG
I believe these options are limited in terms of providing end point for VPN.Is there a VPN module that we can buy for 5520 to run IPSEC VPN?

we have two ASA 5510s one in 8.4(4) and one in 8.2(5) in a site-to-site VPN setup. All internal traffic is working smoothly.Site/Subnet A: 192.160.0.0 - local (8.4(4)) Site/Subnet B: 192.260.0.0 - remote (8.2(5)) VPN Users: 192.160.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible.
Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise.There are also some weird NAT rules that I am not happy with that were created after I upgraded Site A ASA to 8.4
Site A internal: 192.160.x.x External: 55.55.555.201(main)/202(mail)
Site B (over site-to-site) is 192.260.x.x External: 66.66.666.54(all)
I pretty much just have the basic NAT rules for VPN, Email, Internet and the site-to-site.What do I need to add for the VPN to be able to access the site-to-site network?
Here is my NAT config:
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static VPN_Network VPN_Network no-proxy-arp route-lookup
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static DOMAIN_REMOTE DOMAIN_REMOTE no-proxy-arp route-lookup
!
object network DMZ_Network
nat (DMZ,Outside) dynamic interface
object network DOMAIN_LOCAL

I setup RA-VPN under local asa 5510 IP pool (192.168.127.0/24) and all was working fine. I got internet and local network access.
Then i have 5 site to site VPN working fine but when im traying to access to those L2L VPNs from the remote acces client im not able to do that. So after that i decided to obtain IP addresses from my DHCP server so i can obtain IPs from my local network (172.17.16.0/16) and then access normally to the VPN site to site. But the surprise was that the VPN cisco client is getting local IP address (172.17.16.222) perfectly but im not able to access even to my local network.
I have the same-security-traffic permit inter-interface same-security-traffic permit intra-interface enable.

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) :

It's been a long time since I played in Cisco CLI.Using a Cisco 506 Firewall 6.3(4) PDM 1.0?Problem is I created a site to site tunnnel with a vendor and since then our remote VPN does not work. Completely times out so I am sure I broke something in the crypto map or something similar.
Tunnel is policy 10 using access-list 101
Remote VPN is Policy 20

I am attempting to configure Radius authentication accross a site-to-site VPN for my ASA 5510-01 for remote access.
ASA5510-1 currently has a live site to site to ASA5510-2.
ASA 5510-1 - 10.192.0.253
ASA 5510-2 - 172.16.102.1
DC - 172.16.102.10
ASA5510-01 can ping the DC and vica versa but is unable to authticate when i perform a test. ASA5510-01 can authenticate to a DC on it;s own LAN but not on the remote LAN that DC sits on.
I have double checked the 'Server Secret Key' and ports as well as various users which all work locallly. ASA5510-02 authenticates to DC with no problems.

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

At the main site, I have 3 5508 WLCs each part of a mobility group (wlcMain-MG). In NCS, under "System/Mobility Groups" for each controller, I see each controller listed as "local" with the other Controllers listed with the group name "wlcMain-MG". None of the SSIDs are "anchored".
I have a new site with a 2500 series WLC that I would like to push out 2 SSIDs. This site contains two customers. One customer is the Main customer with the second customer leasing space.
I have the Cust2 WLAN at the remote site set to have traffic egress out of a local interface on the 2500 WLC (this traffic is then tunnelled back to their Main location via an ASA which houses the DHCP scope for that vlan). I can connect to this SSID, obtain an IP Address off the ASA and am tunnelling without issue.
For the Cust1 WLAN at the remote site, I would like to broadcast an SSID from the Main location on those same APs which are registered to the 2500. It is my understanding, that I anchor the SSID at the Main site and identically configure the SSID at the remote site. This will allow the end user to authenticate to the RADIUS server at the Main site and be placed upon the correct vlan (we are using DOT1x and dynamic vlans).
For my test, I am starting simple. I have created a test WLAN with no authentication. At the main site, on 5508 WLC3, I have created the test WLAN, and placed the interface into a low security vlan (call it VLAN-low). I have anchored this test WLAN to that controller. At the remote site, I have created the same WLAN (but placed it into the management interface for now - the VLAN-low does not exist at the remote site) and configured that WLAN to anchor back to the WLC3 at the main site. I am unable to obtain an IP address from the remote site. I have placed the remote site WLC in the wlcMain-MG as well. How close does the code need to be on the controllers - the 5508s are at 7.0.116.0 and the 2500 is at 7.0.220.0? What could I be missing?

find attached Network Diagram for the same. All Firewalls used are Cisco ASA 5520.
Both VPN tunnels between Point A and Point B, Point B and Point C too are up. I have enabled Same security level intra interface permit command also.
How do i enable traffic originating from LAN Subnets behind Point A to reach LAN Subnets behind Point C without having to create a Seperate tunnel between Point A and Point C

I am building a site to site VPN from our headquarters to a customer. I am using an ASA 5520. The customer is using Cisco 3945 routers. The customer has two VPN termination points. The customer requests that we make one of their termination points the primary VPN connection and make the other termination point the backup in the event that the primary VPN fails. How do I configure this on the ASA? Does the below configuration fulfill this goal?

We have 3 sites, with a Cisco ASA 5520 at each location.
HQ (Headquarters) internal network: 172.16.110.0/24,
DR (Disaster Recovery) internal network: 172.16.120.0/24
BO (Branch Office) internal network: 172.16.150.0/24
HQ and DR have a 100Mbps permanent MPLS link between each other.Branch Office has a Site 2 Site VPN connection to HQ. If it fails, it establishes a Site 2 Site VPN connection to DR. This works perfectly.Now the routing issue... There is no route to the BO in the routing table at HQ/DR. The default gateway is used to reach the BO and that works for HQ when the VPN is between HQ/BO. If the VPN fails over to DR/BO, HQ can't reach BO anymore.I need to have some kind of conditional route injection from the ASA where the VPN is established. I was considering a tracked static route, but I was wondering if the S2S VPN itself has a functionality to do so. I thought the Reverse Route Injection was it but it's enabled on our crypto map and doesn't seem to work...

We have successfully establish a site-to-site vpn, but we have some difficulties when PPTP users try to access the remote network linked by this tunnel. LAN users can access the remote network without problem, but users who are connected remotly to the lan (PPTP) can't access computer on the remote network. Is there a way to allow PPTP user to access the remote network ? Adding a route ?
