Cisco VPN :: Create A Site To Site VPN Using 2901 And Linksys Router?
Mar 28, 2012
I am trying to create a site to site VPN using a cisco 2901 and Linksys router.I have the VPN configured and connected and I can ping gateway to gateway. However, from the Cisco I can't ping any of the devices beyond the gateway.Example, from the cisco I can ping 192.168.5.254 (gateway IP address) source gig 0/1 and it works great.
However if I ping from the cisco 192.168.5.50 (end user PC) source gig 0/1 it doesn't work.I have created a client VPN and that works perfectly.Below is my config.
crypto isakmp policy 1

We have approx 40 branch offices - all of which are connected to a single core site over VPN Tunnels using various gear. At one particular site, we are having issues with the tunnel dropping sporadically throughout the day - some days it happens 10 times, some days it happens none. This just randomly started happening two weeks ago, without any changes taking place. Since it started happening, I have upgraded the code to latest versions, but still the issue persists. This particular site has a 2901 and connects back to a 2951.
Below is the output from:

Our HQ office has an ASA 5510 with full access to internal and external IP's. We have a small group of remote users that are working from a shared office suite and they only have Internet access by way of internal default gateway. Using a VPN client is not desirable due to many other devices requiring access to HQ. Is there a way to create a site-to-site VPN from this remote office space back to HQ (ASA 5510) if they have no access to the public IP address on their end?

I have a new WRVS4400N configured with a site to site VPN to connect to my office. At the office, we're running a Cisco PIX 515E. I have successfully established an IKE preshared key and the tunnel is listed as Up. I can successfully connect through the VPN tunnel into the office network through the tunnel and all seems good. After some period of time, the tunnel apparently goes into a bad state. Access to the office network is no longer available. When looking at the VPN status screen, the Linksys indicates that the tunnel is up. However, I cannot ping any resources on the office lan. If I disconnect and connect the site to site VPN tunnel, it connects and comes back up successfully. It seems like there is some sort of timeout taking place here. I am running the 1.1.03 firmware.

Today i'm running with an ASA 5510 at the HQ and a ASA 5505 at my home address with a site-2-site VPN connection.
I'm only using the 5505 to hold this site-2-site VPN so it's a bit overkill. I would like a router at my home with build in access point, but it needs to support site-2-site vpn with the ASA 5510 at the HQ.
Are you aware of any Linksys routers that can hold this VPN connection, or is it only "real" cisco routers/firewalls where this is possible?

I need to configure a site-to-site VPN using a Cisco 881 router on my end and connecting to an ASA5510 on my suppliers end.Our supplier has configured their end and I do not have access to their configuration.
They told us we have to NAT all inside address' to a single address (192.168.89.1) as this is the only one they will let through their firewall/tunnel.I know how to set up the VPN but not too sure how to set up the NAT part.
My sanatized config is attached. The code I am using to NAT my inside network to the single address 192.168.89.1, and send all traffic accross the VPN tunnel as this address is correct? With the router running this config the VPN tunnel does not connect.

I have an issue with 2 site to site VPN tunnels from a RV042G router. The issue is for both VPN tunnels is that in the logs, it is showing that when the RV042G router is trying to establish the tunnel, it is getting a response from the remote gateway internal address and not the Public address of the remote gateways. On the remote gateways I have other site to site VPN's terminating fine and the tunnels are passing traffic. I only have an issue with the RV042. On the VPN Tunnel page it shows for both tunnels waiting for connection. This is an output from the log of the RV042G

Just now my boss asked me to prepare to set up site-to-site VPN on Cisco 881 Integrated Services router to ASA 5505 router which is now running at the HQ side. I am now learning pdf file from Cisco which mention how to setup site-to-site VPN between Cisco 1812 IOS router and ASA 5505 router by using ASDM V6.1 and SDM V2.5. Can't find the paper for that Cisco 881 device.

I'm setting up a site-to-site VPN between two offices, Site A uses a Cisco RV110W VPN Router with a static WAN IP and local IP 192.168.1.0/24 while Site B I have set up with a Belkin N300 VPN router which also has a Static WAN IP and the local IP is set to 192.168.2.0/24
I'm able to ping from Site B (192.168.2.xxx) to Site A, however I can't communicate from Site A back to Site B.how I could go about troubleshooting this? I've been scouring the internet for 3 days trying to get to the bottom of this with no luck.

I have recently bought two CISCO routers RV220W for our main and brach office mainly for VPN tunneling. I didnt know they are routers only not modems. so I have set it up using BT 2wire Router as modem only.
I have successfuly setup the routers and manage to establish the VPN tunneling between two routers. AS bt doesnt give static WAN IP address so I have used Dyndns which works fine. although I have 5 static ip address which cannot be used for WAN unless i cahnge to one IP address even then BT tech said it will not work.
when I created the tunnel i could ping both servers with their IP only not with the names. I can ping them fine locally. I could also see the network from branch office to main office but not from main office to branch office. today when I restarted the server I cannot ping both server i mean vice versa but VPN tunnel is established. now I cannot see the network from branch office to main office as well.
Both sites running windows server 2008 standard. main office server has 6 NIC cards two wwith public and three with private ip addresses, its also runing Terminal server, exchange, file etc. the branch office has two NIC card one with private and one with public ip. Intially I could establish the VPN tunnel as the network range was same on both sites so I changed one in th e10.0.0.0 range other in 192.168.1.0 range and VPN tunnel was established straightaway.
As soon as the VPN tunnel was created I manage to creat an external trust without any problems and both servers are added in each other forward zones as name servers.
in the main office the fues went off and I had to re-start the router and now the VPN tunnel is not establishing, mainly the error is ISAKMP-SA Expired I will paste the log of both routers below
1. How to Clear Old or Existing Security Associations (Tunnels) on RV220W
2. how to fix the problem where I can ping the server with their IP as well as domain names ?
3. how to set it up so that both sides can see the network resources as well as access it ?
4. how to set it up so if the staff in branch office wants to log on the domain in main office he can simply do it as he does it in his office.

I'm setting up site to site VPN on a RV110W router. The administrator guide site to site instructions don't match the options on the router.The first step tells you to click on VPN then Basic VPN Setup. The router under the VPN option only has three choices, (1) VPN Clients, (2) Certificate Management and (3) VPN Passthrough. I have upgraded to the latest firmware 1.0.0.9.

I'm looking to configure a DMVPN spoke with a Site to Site VPN Connection to a different destination than the DMVPN. I'm using a Cisco 2800 router. When I add the crytpo map to the outside interface for the Site to Site VPN. The DMVPN drops. Is there something I could be missing? The Tunnel interface for the DMVPN has the shared optioin applied to the tunnel protect ipsec profile.

I have a remote office with a dual WAN router (2911) in front of an ASA (5510). Our main office currently has an ipsec site to site vpn to that remote office ASA. The router has two ISPs. ISP-A is the wan link used for the site to site and has provided us with a /28 public address space which we use on the ASA outside interface for the site to site. Now we are in the process of getting a second ISP which will also provide a /28 or /29 public address space. I would like to use that second ISP for backing up the site to site in case ISP-A link goes down. I think I have the IP SLA config worked out. My question involves NAT. On the router I would like to configure a static nat that only takes place if ISP-A goes down. In other words, if everything is working fine, then the router does not nat the ASA outside address, but if the ISP-A link goes down, then the router will NAT the ASA outside address to one of ISP-B provided public addresses.
