My company paid a Cisco 1941 SEC/K9. There is no VPN SSL Licence. I would like to know if I can configure IPSec tunnels basically on my router?
In this case, how many IPSec Tunnels I can configure?
how configuring IPSec Tunnels on my router?
ASA 5505 8.2.1
ASA 5520 8.4
We currently have a tunnel configured between 2 ASAs
1- Is it possible to assign 1.5 Mbits of Bandwidth(BW) to this tunnel?. Then if Tunnel number 2 is configured I could assign 2 Mbits to that one for example?
I am not referring to prioritizing certain type of traffic over the IPsec tunnel, I am referring to Tunnel 1 has 1.5 Mbits of BW guaranteed for all traffic that goes thru it. Same for tunnel 2
Then
2- How to monitor the amount of BW in an IPsec tunnel?
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've been reading this site for a while, and finally decided to post I'm really interested to see what everyones opinion on this is.My company currently uses what i would call traditional site to site VPN's using crypto maps, main site has a pair of ASA's in HA and remote sites use ISR's like 1801's.I've recently been playing in my lab with GRE tunnels using IPSec protection (note this is config from my labs, so ip's and key's are just randomly selected)

View 0 Replies View RelatedWe have many VPN tunnels back to our corporate office. All of these tunnels are very slow (same with our client VPN's). Our main firewall device at the corporate office is an ASA5510. We have a 100 Mb/sec Metro Ethernet internet connection here. We do not allow split-tunneling.
Our remote sites vary. We have DSL connections, cable internet connections, and other types of broadband that vary in speeds from 5 to 100 Mb/sec (up and down). The remote sites mostly have PIX 501's, but we have an ASA 5505 in one of the locations.
To take an example. On one of our remote sites that has a 100 Mb/sec connection, if I ping device to device, I'm getting ping times of about 50ms. And I'm pinging back through another 100 Mb/sec connection. If I get on a computer down there and run a speed test, I'm showing down speeds of about 1.5 Mb/sec... nowhere near 100. Some of that could be due to the lack of split tunneling, but I also suspect this could be an MTU issue.
Right now, all my MTU's are just set to the default 1500. Perhaps this is too high. I used this site to check my max: [URL]
I did a few tests from behind several of my firewalls. I pinged from a machine on one side of the tunnel to the firewall on the other end. I'm assuming the max MTU I come up with is the max MTU for the firewall I'm behind while pinging, right? The max amounts I came up with for some of my devices were as follows: Corporate ASA 5510 > 1272 (if you add the 28 byte packet header that would make it 1300) Remote PIX 501 > 1416 (if you add the 28 byte packet header that would make it 1444) Remote ASA 5505 > 1418 (if you add the 28 byte packet header that would make it 1446)
So, do I just need to set my MTU values to the appropriate amounts? I have tried changing the value, but I don't see any change in speed/performance. But I also don't know if I need to reboot the firewalls after changing the MTU. I know with Catalyst switches, you have to reload. But I didn't see any messages about needing to reboot on the ASA's/PIX's.
I tried looking in ASA documentations but unable to find out that how many IPSec Tunnels can be terminated to an ASA cluster. I have 5545 running only two IPSec Tunnels so far but need to terminate 18 sites all up and would like to confirm how many tunnels we could terminate? Is there a limitaion to it?
View 2 Replies View RelatedI 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 have an issue where I can get traffic to pass from HDQ to two branch offices over our ipsec/gre tunnels even though the tunnels appear to be UP. The HDQ is a 2811, branch is a home office using an 871W and branch runs a 2801 router. I initially had HDQ working fine with the 871W but when I configured branch2 (2801), they both broke. The tunnels appear to be up but traffic is not routing across them. The two 2801 routers run 12.4 (c2800nm-adventerprisek9-mz.124-24.T2.bin). These are gre over ipsec tunnels. Currently traffic flows over an exsting MPLS network that we are getting away from due to cost. As soon as I change the routes to point to the Tunnels, it breaks. Traffic doesn't appear to pass through the tunnel. I have attached my sanitized configs.

We have a number of sites running Cisco 881 routers. A few of the sites are connected by IPSec VPN tunnels that have been configured using Cisco CCP without any issues until now. On one location I can ping from a workstations on Site1 to Site2, however I cannot ping from the same workstation on Site2 back to Site1.
Here is a strange behavior. If I have a continuous ping going from Site1 - Site2 and then start a continuous ping from Site2 - Site1 then I get a response until I stop the ping from Site1 - Site2. Site 1 has approximately 5 successful tunnels with absolutely no issues.
Here is some site specific Info:

For additional troubleshooting I established a VPN tunnel from Site2 to our office Site3 with no issues at all. Site3 happens to be one of the VPN tunnels that connects to Site1 with no issues. I have seen a number of articles on this on the net and gone through the troubleshooting steps of an article such as [URL]. The tunnel is confirmed as up when I have done all my troubleshooting.
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 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.

We have a business need that we have to set up a IPsec L2L tunnel (from multiple locations) to a business partner, we require that the connection can only be initiated from our side, not business partner side. I searched the web, one option is configure our side ASA to initate IKE only, this does not seem to meet our requirement, because once IPsec SA is up, IP layer traffic will flow freely in either direction; the other option people suggested is to use VPN filter in tunnel group policy, but the documention of how to use this vpn-filter to enforce one way traffic policy is not crystal clear to me; I actually configured reflexive ACL on core L3 switch before the traffic hits ASA to reflect/evalulate specific traffic to businness partner's LAN network, that worked well. However one of our branch office's core L3 switch is Cat4K which does not support reflexive ACL with the image it is currently running, so I am stuck again .

View 2 Replies View RelatedI'm attempting to configure a tunnel on a PIX-501 version 6.3. It's an old device that's due to be replaced soon, but unfortunately we need a tunnel now... I have been using this document as a reference (6211): URL ,The remote end is a sonicwall.
The problem seems to be that the pix never sees the interesting traffic for the tunnel, and never tries to initiate a connection. I have enabled crypto ipsec and crypto isakmp debugs, but no data is ever displayed, even when attempting to access a device on the remote side of the tunnel! Someone had tried to set up this device with some tunnels in the past, but was never successful, so I'm thinking there might be remaining commands in the running-config causing problems.
I have 2 Cisco 2811 routers that are installed in different locations. I set up a tunnel connection between the two routers.

How to configure an IPSec VPN with router RV042G.I need to know how to configure an IPSec VPN. Cisco Router with RV042G.
I spend this client your VPN parameters. [code]
We have purchased a couple of Cisco 891 routers - both are running IOS 15.0(1) M5 licensed with advanced IP services (default). The literature for these devices on Cisco's website claims they support IPsec stateful failover on advanced IP services.
Our intention is to configure them with HSRP and IPsec stateful failover to provide a highly-available default gateway and VPN end-point.
I have configured HSRP and that seems to work fine. My problem is that I cannot configure IPsec stateful failover. The documentation that I have found implies that I need to configure inter-device redundancy on a particular HSRP group and use the physical IP addresses on the interfaces within that group to allow stateful failover communication between the routers however the routers do not recognise the 'redundancy' command in config mode...
e.g.
(config)# redundancy inter-device
