Cisco VPN :: 1841 / VPN Site-to-site With Zone Based Firewall
Jan 28, 2013
The problem I am having is very strange and I have tried to upgrade the IOS on the 1841 to solve the problem but no luck. The issue is when I enable Zone Based firewall security on of the 1841 routers two VPN site-to-site tunnels stops working. If I turn off CEF (no ip cef) then the traffic for both tunnels works. Someone told me that the Zone Based firewall must have a match for the VPN traffic and I created that with ACL 160 and 161 but it did not solve the problem.
Current IOS is below.

I have a cisco 1841 router , and i want to configure zone based firewall on it. But the document of zone based firewall only said that "after 12.4(6)T" can support zone based firewall. I use the ios " c1841-ipbasek9-mz.124-15.T9.bin ", but it can't support ZFW. What kind of ios support ZFW. for example: ipbase, ent base, ip service ,advent etc.
I want to implement site to site vpn among our Head Office and Barnch routers (300 Sites).Head Office Site I have a cisco 7200 Router Im going to terminate the VPN conection on that.Branches we are having cisco 1841 series routers. They all are capable of working with VPN.In the present it is act like a EazyVPN Server for selected sites(30 sites).Is there any license limitations in Cisco 7200 Router ?Can I run both Site to site VPN and Eazy VPN Server together ?
Using the Cisco Configuration Professional software I have created a site to site VPN connection (between a cisco 1841 and 1811).The tunnel appears to be up as far as the routers are concerned, but I am unable to ping anything on the remote networks. I thought route maps may have had something to do with this but I cant see what is worng with them.Just so you know, the 1841 device already has a functioning VPN tunnel to another site. The peers I am concerned about are 141.0.59.x and 109.238.78.x.
I am in the process of setting up a site to site VPN connection with a Cisco 1841 with the AIM-VPN-SSL-1 module and an NEC IX2015. We are using a GRE tunnel with IPSec.The problem we are having is the NEC router will not repsond to ICMP packets (and there isn't a way to make it respond). Will this cause any problems with the tunnel?
Is there a guide to set up a site to site VPN using 1841.
I have 3 points, 1 1841, 1 pix 506e and 1 ASA 5500. I need a good guide/manual to set up this. I would like to connect to any of the points, and be able to see all the infrastructure.
i have 2 routers both 1841's and am trying to get a simple static vpn up and running. Now One router is at our main location (ill call it router a) and the remote location (ill call it router b). Both have internet connectivity that works, can ping router a from b and b to a. Now on router b side when i run show crypto isakmp sa on router b i get the following:
SBOneonta#show crypto isakmp sa IPv4 Crypto ISAKMP SA dst src state conn-id status 72.43.229.138 66.194.51.66 MM_NO_STATE 0 ACTIVE (deleted) 72.43.229.138 66.194.51.66 MM_NO_STATE 0 ACTIVE (deleted) 72.43.229.138 66.194.51.66 MM_NO_STATE 0 ACTIVE (deleted)
[code]....
i72.43.229.138 is the router and the other ip is i have no idea! its no where in the config, but that shows me this router is trying to do something. Now on router a when i run the same command i get this:
show crypto isakmp sa dst src state conn-id slot status
a whole lot of nothing! now i have been working on this for a few days now and i cant understand why i cant get this simple vpn tunnel to work! I have debuging on both routers, router a shows nothing period for vpn traffic, router b shows a connection from the 66.194.51.66 which again i have no idea who or where this ip is and its not in the config any where.
I have an 1841 that I set up to do site to site VPN between my company's network and an external network. This has a backup connection point. All works well including automatically failing over to the backup site.
We also want to be able to VPN remotely to our company's network using the same 1841.I have tried many different ways to configure this, but the best I had resulted in an external VPN request taking down the site-to-site link.
Is this possible? Our internet connection is through an ADSL router set up with pasthrough, then into the Cisco 1841 which does the dialer PPPOE authentication.
How many site-to-site VPN can we establish in Cisco router 1841. When we start 1841 we get the message that VPN Module 1. What is the meaning of it, does it mean that we can establish only one VPN. How about the limitation of GRE VPN Tunnel.
I have a requirement to create a site to site vpn tunnel on ASA 5510 from a remote site to my HO, ihave already other site-to-site tunnels are up and running on the ASA.The issue is my remote site has got the network address which falls in one of the subnet used in HO(192.168.10.0/24).My requirement is only My remote site need to accees couple of my servers in HO which is in 192.168.200.0/24 subnet.
I have a request to establish a site to site VPN with a customer. While collecting the information I give them our local network subnet which is a private subnet (192.168.5.0). They asked me if I could give them a public address instead. They can not work with the 192.168.5 subnet. Is this possible?
My side of the VPN is an ASA 5505 running 8.2(2). The other side i believe is a Checkpoint.
Got an ASA5505 connected to another endpoint running IPsec and being NAT'd at each end to a 10.0.0.0/24 network. I can pass other types of traffic through the ASA 5505 but not RTP traffic. The moment it is NAT'd and hits the firewall rules it gets denied by the default deny at the bottom of the list.
Currently the rules are as follows
Incoming External allow ip any any allow tcp any any allow udp any any default deny
[code].....
It wont allow us to setup a voip call...however when the same call manager sets up a voip call NOT using this ipsec tunnel it works just fine.
I am try to configure ASA 5510 with 8.3 IOS version.My internal users are 192.168.2.0/24 and i configured dynamic PAT and are all internet .
i want configure identity NAT for remote access VPN.Remote users IP pool is 10.10.10.0 to 10.10.10.10
i know to configure NAT exemption in IOS 7.2 version. But here IOS 8.3 version. configure NAT exemption for 192.168.2.0/24 to my remote pool( 10.10.10.0 to 10.10.10.10).
I have a ASA 5510 at our corporate HQ that has one site to site VPN. I need to add 6 additional site to site VPN's to this ASA for our remote branches. How can I add them without affecting the existing site to site VPN? The 6 site to site VPN's will all have the same settings however these settings are different from the existing site to site that I already have set up. How can I set it up so the 6 additional VPN's use their own crypto map and all use the same settings?
We have a client that has a Cisco 1801W Firewall that is setup as a site to site VPN terminating to a Cisco ASA 5505. The tunnel is up and established, I can ping from both sides of the tunnel.
The problem is the clients behind the Cisco ASA (192.168.2.x) cannot reach certain ports behind the Router (192.168.1.x). The main thing we're trying to do is browse via UNC path (ex: \192.168.1.120 from a 192.168.2.x machine).
I got 3389 working after I changed the - ip nat inside source static tcp 192.168.1.120 3389 y.y.x.x 3389 route-map DM_RMAP_1 extendable Modified the command to include the public IP instead of interface FastEthernet0
I believe it has something to do with the way NAT and route-maps are setup currently but I'm not familar enough with them to make the changes. I worked with Cisco to ensure the VPN tunnel was fine and it's something security related on the Router.
Here is the configuration (removed a few lines not necessary. y.y.x.x = WAN IP of Router x.x.y.y = WAN IP of ASA).
Building configuration...
Current configuration : 23648 bytes ! version 12.4 no service pad
I have a ASA 5510 that has multiple site to site VPNs. I need to create an additiona site to site VPN but only allow 1 host to access and traverse the tunnel. The network is on a 192.168.5.x but the host that will need to access this tunnel needs to be on a 172.16.33.x network. I dont want any other traffic allowed to access or traverse the VPN tunnel for this host. How can I set this up?
I've set up a standard site-to-site VPN between 2 ASA 5505s and the VPN is working fine for traffic between these ASAs and computers which are in the same LANs.but when I'm trying to connect to computers which are in another VLAN I have a problem.
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 have weird problem with a Site to site VPN tunnel from a Cisco ASA 5505 to an Clavister Firewall.When I restart the Cisco ASA 5505 the tunnel is up and down,up, down, down, and I get all strange messages when I see if the tunnel is up or down with the syntax: [code]
After a while like 5-10 min the vpn site to site tunnel is up and here is the strange thing happening I have all accesslists and tunnel accesslists right I can only access one remote network (Main site Clavister Firewall) trought the vpn tunnel behind the Cisco ASA 5505, and I have 5 more remote networks that I want to access but only one remote network is working trought the vpn tunnel behind the Cisco ASA. I see that when I do this syntax in ASA: show crypto ipsec sa.They had a Clavister Firewall before on that site before and now they have a Cisco ASA 5505 and all the rules on the main site thats have the big Clavister Firewall is intact so the problems are in the Cisco ASA 5505. [code]
All these remote networks are at the Main Site Clavister Firewall.
I wanted to know the maximum VPN client sessions (using the Cisco VPN client) and Site-to-Site VPN tunnels that I can connect to my ASA 5505 simultaneously.
In other words, if I have x VPN clients and y Site-to-Site tunnels, at any time, does x + y have to be <= 10 (Total VPN Peers)? If yes, can I upgrade to the security plus license to increase the Total VPN Peers to 25?
Licensed features for this platform: Maximum Physical Interfaces : 8 VLANs : 3, DMZ Restricted Inside Hosts : Unlimited Failover : Disabled VPN-DES : Enabled [Code]...
I'm having slow performance thru a Site to Site VPN. I have an ASA 5520 in each site with the version 8.2(4) in both ASA's. I have a 20Mb internet service in one side and in the other side I have 50Mb. When I transfer a file from the Sita A to Site B I get a transfer rate of 130KB/S.
I have a 5505 asa code version 8.3(2). Trying to set up a site to site tunnel with someone and he is asking if I can use ike v2. How do I go about setting up the tunnel to use ikev2? Is ikev2 an option with site to site tunnels?
I have cisco pix connected at the edge of my GPRS network. Inside is the GPRS core network and outside is the ISP.On cisco pix, i have site to site IPSec configured between my inside GPRS network and Blackberry servers. for blackberry services.Using the ASDM I can see the total number of packets in and out on this site to site IPSec, but if I want to measure the trand of the bandwidth utilisation over this IPSec, per sec, then how can I do this? I have PRTG traffic monitoring, through which I did try, several MIB (listed below) but still not able to find the correct way. how can I get the measurement for the IPSec from cisco pix?
Site A - headquarters 192.168.1.x Site B - remote office 192.168.20.x Site C - remote office 192.168.30.x
Site A - ASA 5510 Site B - ASA 5505 Site C - ASA 5505
Site-to-site VPN is established and works between A and B, A and C. Users would like to establish a tunnel between B and C to work on a common project and the data is on Site B.
I tried configuring the S2S VPN with pre-shared keys on both firewalls at sites B and C but in the end it is not established (I cannot ping either side). I used the Wizard interface multiple times and one time the CLI. I generally followed the settings chosen between the headquarter and the individual remote sites and tried to replicate them. Obviously I have made a mistake somewhere.
Could there be any limitation on the ASA 5505 in terms of licensing and the number of S2S tunnels?
We have got site to site VPN configured between local site with PIX515 6.3(5) and remote site with ASA 5505 7.2(4) . Because of very unreliable internet connection in remote site , we have added new ISP link which we want to use as redundant link .i understand ASA 5505 can be configured with two ISP link with SLA monitor method for redundancy as per this document ,[URL]
my question is how do i set up this pix 515 to have redundant VPN tunnel with remote site (when primiary ISP link fails in remote site and secondary ISP links takes over ) . I was thinking of using PIX 515 with 2 peers in same crypto map used for that sepcific site to site vpn tunnel,not sure that is the right way or not though.But how would i configure ASA 5505 to use backup interface(where secondar isp router conects ) to particitae in Site to site Tunnel .
We have a Cisco ASA 5510 at our main office that makes connection with a 5505 at our other office using site to site VPN. (works)
Now for the question,
we want to access our other office from the main office but we wont want them to have access to our servers etc. so basically we want to control them but they shouldn't have the rights to control us.
Is this possible with a site to site VPN? and how to do it.
We are setting up a new phone system using the UC540 with a VPN connection between 2 buildings using 2 Cisco ASA 5505's at either end.The problem I am having is getting the phones at the remote site to connect to the UC540 at the main site.
What i am told by UC500 support is that the phones at the remote site will connect if they have connectivity to the TFTP subnet on the UC540, which is 10.1.10.0/30 I added the static route on the ASA and I can ping the 10.1.10.1 TFTP server on the UC540 from the ASA, but not for any other device on the 10.0.0.0/24 network, such as the DC. I added the static route there and was able to ping, so something in the ASA seems to be preventing it.
I also can't seem to get the ASA at the remote site to ping 10.1.10.1. I've tried adding the static route there in hopes it would forward it through the VPN tunnel.
I have Cisco 3560X L3 Switch. We have done Inter VLAN in our internal networks. Below are the VLAN details
Default VLAN1 IP 192.168.125.2 (Gi0/1, Gi0/23, Gi0/24) Interface Gi0/1 (Port Configure as a Trunk) Interface VLAN 10 SERVERS_SW (Gi0/2 to 0/6) IP Address: - 192.168.0.1 255.255.254.0 Interface VLAN 20 USERS_SW (Gi0/7 to 0/18) IP Address: - 192.168.152.1 255.255.248.0 Interface VLAN 30 SPARE_SERVER_SW (Gi 0/19 to Gi 0/22) IP Address: - 192.168.8.1 255.255.248.0
We have Sonicwall NSA2400 Firewall and we have setup Site-to-Site between our other offices who has Sonicwall TZ210 firewall. It works fine and they are able to access all the above networks.
Now the problem is we have one more site which uses Vigor Firewall (with Internal Network 192.168.100.0). We have setup the site-to-site vpn between Sonicwall NSA 2400 (Lets say SITE A) and Vigor (Lets say SITE B) but SITE A is unable to ping to SITE B Firewall but SITE B is able to *ONLY* SITE A firewall.
SITE A is trying to ping from User VLANs whose local ip is 192.168.152.0 range.
How to add route to 100.0 so that we will be able to ping and access SITE B networks.
