Cisco Routers :: Setup VPN Tunnel Between Linux Machine And RVS4000 At A Remote Site?
Jul 21, 2011
I'm trying to set up a VPN tunnel between a Linux machine and a RVS4000 at a remote site (served via satellite connection). After many efforts, I finally succeeded (based on Openswan). However, while PINGing is OK, big packets (from the RVS4000 LAN to the Linux box) arrive corrupted.
I lowered the WAN MTU, with no success. What finally did the trick is to lower the MTU at the RVS4000 LAN interface. Since this is not possible via the Web I/F, I did it via telnet ("ifconfig eth0 mtu 1400"). However, this change is lost after router reboot. How can I make the LAN MTU setting permanent?

I bought 2 RV180 to setup a VPN tunnel between a remote site and central office.The VPN tunnel is established, I can ping from central office to remote site but browsing on that server fails. [code]
Seems the routing is not really working through the VPN Tunnel.

We have an RVS4000 router at two ends of a VPN tunnel. The VPN tunnel is working fine, however a phone at the remote site drops calls, even though they sound clear and unblemished. I have set highest priority on the port the phone is hooked up to at the remote site, and have set a priority for upload traffic on both routers, but the phone stills drops calls after 2 to 3 minutes.

I am monitoring 2 or more source interfaces which are running 1G traffic on each interface. Destination is 10G interface.There are 2 kinds of traffic running through the source interfaces: icmp and regular IP traffic. I am only interested in capturing icmp traffic. How can I achieve my goal?I don’t have any vlan traffic at all. Router is c6500.

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

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?

I have a situation where I need to have remote users vpn into my ASA 5510 and then turn around and hit a site to site tunnel. Now when I am in our office I can hit the site to site vpn fine. When I am at home and vpn to the asa I can not get to the site to site resources. Do you see where my config is incorrect? result of the command: "show run"

I have an GRE Tunnel across my head office and remote site with multiple subnets using cisco 1841 routers.I can ping most of the devices on the remote side, but I can not ping certain devices.These devices respond to ping requests on the local LAN, but not through the WAN link. If I change the IP of device than it start responding. I am using same gateway and mask on these devices.The remote site is running classic STP on switches with distribution switch being the root bridge.

How can I set up a Cisco 831 router (branch location) so that it will accept inbound VPN Client connections and initiate a site-to-site IPSec tunnel to our hub location that uses a VPN 3005 Concentrator? I could get the tunnel to work by configuring it in a dynamic crypto map but interesting traffic on the Cisco 831 side would not bring the tunnel up.

I have succesfully config an IPSec VPN Tunnel by using a Router Scientific Atlanta Cisco 2320 and a RVS4000 4-Port Gigabit Security Router with VPN.On the site of Router Scientific Atlanta Cisco 2320 this is some info: [code] On the site of RVS4000 4-Port Gigabit Security Router with VPN this is some info: [code] Remember that you can not be on the same range of IP, I mean, you can not have 192.168.0.X if the remote network is on 192.168.0.X, you have to change some of the Routers.I show the configuration on Router Scientific Atlanta Cisco 2320: I show the configuration on RVS4000 4-Port Gigabit Security Router with VPN:If all is correctly configured, you should see on Router Scientific Atlanta Cisco 2320 the Status Connected:
If all is correctly configured, you should see on RVS4000 4-Port Gigabit Security Router with VPN the Status Up.As you can see, I'm connected to the remote Router (RVS4000 4-Port Gigabit Security Router with VPN) by my own web browser accesing by the local IP 192.168.0.10.I have used Authentication MD5, maybe is not the best one but I had no time to test SHA1, I will when I will have time.

Is it possible to have a site-to-site IPSEC tunnel between 2 identical RV110W routers?I basically want one of them to initiate a secure tunnel with the second so that computers from one router subnet see the computers from the other router subnet.

the RV110W IPSEC site-to-site tunnel, are there necessary 2 x public IPs for it to work, or only 1 public IP is enough? [code]If it works with 1 public ip, the "CLIENT" RV110W configuration should be straightforward (in Advanced VPN SetupRemote Endpoint i fill in the dyndns address?), but how do i setup "HOST" RV110W?

As you can see i have problems with connecting 2 SRP521W together for an VPN tunnel. I tried as much as I can but now i dont know what to do or how and where is the mistake? the connection between these two devices was there last week, after weekend (nothing changed in configs) the connection suddenly was interrupted, without any reason or warning. another day it worked again and 20 mins later connection was dead again...and now it wont establish at all.. here are some screenshots from the vpnconfigs of my devices. one has a static IP the otherone uses FQDN. These are the IKE policies: Here the IPsec Policies: and the GRE policies:

I have a site to site VPN tunnel configured between a rv220w and rv180. Everything works fine going from site to site on LAN connections. I'm now trying to tie in the remote site wireless (rv220w side) by pointing radius to my ACS server which is on the other side of the site-to-site tunnel but it seems as though it doesnt route across the site to site tunnel. If i put a radius server on the local lan on the remote site that authentication works fine. I have confirmed there are no ACL problems. the RV220W capable of using a radius server across the vpn tunnel?

I'm replacing my RVS4000 with the RV180 but having VPN connection issues with the RV180. Let me know the VPN tunnels work perfectly fine on the RVS4000.I have configured my RV180 for 3 VPN tunnels. My ISP is Comcast (cable) Business class with a Static IP. First VPN tunnel is to another Comcast ISP and the VPN works flawlessly - connects immediately.Second VPN Tunnel is to Business class ISP (Verizon-NJ) and VPN will NOT connect.Third VPN Tunnel is to Business class ISP (Cox Network-VA) and VPN will NOT connect.I had opened both the RVS4000 and RV180 up on a browser and both settings from the units were idential. I reconnect the RVS4000, VPN tunnels work great, I unplug and reconnect the RV180, the Comcast VPN works, but the other two do not.From what the log is saying "[IKE] WARNING: no phase2 found" and the other says "[IKE] ERROR: remote identifier not found". It has to be something with the RV180 that I'm missing or possibly configuring incorrectly.

I recently purchased a RVS 4000 (firmware V2.0.0.3) and am having some issues creating a second (third...fourth?) IPSec VPN Tunnel. The first one is up and running just fine. On the VPN Summary screen it says [1 Tunnels Used 4 Tunnels Available].
When I go to configure the second tunnel, I select --New-- from the "Select Tunnel Entry" drop down and proceed to fill in all the connection information. When I click Save, it seems to be processing and after a few seconds just returns me to the same screen, with none of the information I just input and no connection created. No errors given.
I have another RVS4000 to connect at a different location which will require a similar setup, but don't want to do anything with it until I have the one mentioned above working fully.

I have two routers on my internal network.
10.10.199.106 is a Cisco ASA5510.
10.10.199.108 is a Sonicwall NSA 3500
The sonicwall handles our site to site VPN tunnels. The Cisco handles our client to site VPN connections.
I have a unit that points to 10.10.199.106 (Cisco) for internet access. All other clients on the network point to 10.10.199.108 (Sonicwall) for internet access.The device in question, a Synology NAS, is using 10.10.199.68 as it's IP address.
I'm trying to hit the web interface on the NAS from a remote site across our VPN tunnel. The IP scheme on the remote end of the VPN tunnel is 192.168.72.0/24.
Going through the VPN, I can hit every object on the network that uses .108 (Sonicwalll) as it's gateway. However, I cannot hit the unit that uses .106 (Cisco) as it's gateway.
I added a route statement (using ASDM) that routes all traffic destined to 192.168.72.0/24 to the Sonicwall so it can send it back down the VPN tunnel. If I'm understanding routing correctly, this should allow responses from NAS destined for 192.168.72.0/24 to go back down the VPN tunnel.

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 ?

My RVS4000 router freezes up when a lot of data is being pushed through the Ipsec tunnel. Let me explain in detail.
On physical location A, I have an RVS4000 router (with IP 192.168.3.1) which is permanently connected with a WRVS4400 router (with IP 192.168.1.1) on physical location B. The Ipsec tunnel has been configured using the Easy Setup Wizard of Cisco and has been working fine and stable for months. Both routers have another Ipsec tunnel with another WRVS4400 router (with IP 192.168.2.1) on physical location C, but this router does not play a role in the problem below.Recently, I’m trying to set up a remote backup service between physical location A and B using “rsync”, which uses port 873. Due to the Ipsec/VPN tunnel, I could configure rsync to move the backup files from our NAS on location A (NAS has IP 192.168.1.2) directly to location B (NAS has IP 192.168.3.2). Both NAS-devices are of the brand Synology (DS211J). The Ipsec tunnel guarantees that the data is coded and thus secure.
However, when pushing the first batch of data, I noticed that the router on the receiving end (RVS4000) freezes up after approx. 1,5h after the batch has started, which is after approx. 1 gigabyte of data has been transmitted. The connection with the WAN is lost, also the VPN-tunnel is not working, I cannot ping the device or reach its configuration pages (on 192.168.3.1), the only option is unplugging it and letting it reboot. I’m thinking the router cannot deal with the huge amount of data that needs to be decoded. I tried 5/6 times, with always the same result (timing / amount of data pushed through before router freezes varies slightly).

I have a RVS4000 at one location and a second RVS4000 at home. I have established an IPSec VPN tunnel between them and it is UP. I can ping the routers from each end no problem. I can ping the IPs listed in the "Local Group Setup" and the "Remote Group Setup" from both ends no problem. I can even open up a shared resource from a Win 7 machine (e.g. by typing \10.10.10.100 in start-run from a computer on my home network).
But - i can't ping anything else on one network from the other. What gives? I need to access a 10.10.10.101 machine but can't even ping it.
- both RVS4000 boxes have latest firmware (V1.3.3.5)
- home RVS4000 setup with IP 10.10.11.1
- home network has a server with IP 10.10.11.20
- other location RVS4000 setup with IP 10.10.10.1
- other location server setup with IP 10.10.10.100
Tunnel settings on home RVS4000 (the other location properly mirror these).
- Local Security Gateway Type : IP Only
- Local Security Group Type : Subnet

I configured a RVS4000 router to work a VPN terminator for remote users, like traveling or work from home staff. The Cisco quickVPN utility works as it shows VPN connection is successfully connected. However I can not ping any IP address in my office network.
The laptop is windows 7 64bit. The office network subnet is 192.168.1.x/24. Home network subnet is 172.24.105.x/24.I also did "route print" after quickvpn showed me successful but I do not see anyroute about 192.168.1.x.BTW, I openned QuickVPN as administrator and disabled windows firewall while using QuickVPN.

I am getting ready to setup an RVS4000 so we can use the VPN functionality of it, but I am not quite sure of the correct way to integrate it into our network though. I do not need site to site, just the client portion of it for a few salesmen/off site people to use. I have never used or setup a VPN before, so I'm learning everything as I go along.
We are in the middle of switching our ISP and I am waiting to set this up until the new service is live so I can test it prior to moving the rest of the company to the new ISP.
We are switching to Comcast, and will have 5 static IP's available to use. Currently, the firewall does all our NAT and is the forward facing device on our network. I would like to leave the firewall in place (although I am setting up a new firewall for the new internet connection) and have th RVS 4000 sit behind it and receive VPN traffic from a WAN to LAN rule We currently have a 192.168.100.0/24 network.
Do I need to setup another /24 network for the VPN to function behind (and still have access to the 100.X network), or is there a way to allow everyone who connects to receive a 100.X ip address from our DHCP server. I'm not sure how to set everything up with the WAN/LAN connections on the RVS4000 to acheive this.
We are running a domain on a 2008R2 server. The clients will be using laptops that are already part of the domain, if that will make a difference.
