We have to setup an IPSEC tunnel for a client that does not what to exchange private IP address information for security and overlapping address space reasons. We will both be natting our source private ip address space as public IP address space and send those packets through the established tunnel. Im using a Cisco 3000 concentrator.
View 1 RepliesI have been trying to setup a LAN-to-LAN VPN between two sites that are using a 3000 series CISCO Concentrator. After following the basic setups from the CISCO site, I am still unable to create a tunnel. At the moment I'm starting to believe it is how I have physically setup the network. Site 1 is using a Billion BiPAC 7404VNPX ADSL2+ Modem, Site 2 is using a Netgear DGN2000 ADSL2+ Modem, The VPN Concentrators are setup behind these devices with each firewall setup to allow the needed ports forwarded.

The Conncentrator is currently setup several groups of users and the base group is set up to all other products to connec tin via a pre shared key. It took alot research to get it configured to this point and all the searches i pull up are for a ASA.
I have a VPN Concentrator 3000 with LAN-to-LAN DES-56 connections connected to it (Cisco PIX 506). Everything was working fine and then over the night something messed up on it. No settings were changed or anything.
First issue was anything using DHCP (getting IPs from the sites local PIX) couldn't be pinged or reach out through the Concentrator. It was only Thin Clients that didn't work. I could still ping the PIX, printers and desktop computers that were static set IPs. But this was happening at every site going through this Concentrator. The sites going through out MPLS network are fine.
I tried setting the Thin Clients to a static IP but still couldn't ping them.
I then decided to reboot the Concentrator, when it came back up all sites reconnected back to the Concentrator but now couldn't ping anything at the sites, not even the LAN IP of the PIX (or printers and desktops now). I power cycled a few of the sites PIXs but they still were not pingable even though the Concentrator showed they were connected.
I then decided to physical power cycle the Concentrator, it's back up and all sites are connected but none of the devices on the LAN side are reachable.
The Concentrator can ping the sites WAN IP but nothing on the LAN side going through and out the Concentrator. It can ping the LAN through the private interface (going back towards my LAN) just not going through the public interface (over the WAN).

I have 3000 concentrator in 192.168.1.x/24 network (concentrator has static IP of 192.168.1.4/24 assigned to its private int). I can manage it thru HTTP from any PC in the same subnet, but connection failes while trying to connect from PC on different subnet (i.e. 10.1.1.x/24). Is there ACL in concentrator config which needs to be modified to allow management from different subnet?

The problem is that the normal VPN Dial-up connection (a utility of windows) are getting connected but Cisco VPN Client throws error 412. Here's what I've tried (Initially groups and user were created):
(1) Allowed port 10000 on PIX ( access-list from-outside-coming-in permit tcp any host <public ip> eq 10000) and checked IPSec over UDP on VPN Conc. under Mode Config tab. Also checked IPSec over TCP tab under tunneling panel at port 10000. Tried connecting through VPN Client but it threw error 412
(2) In the reference guide, I read that IPSec over NAT is allowed on ports ranging from 4000 something to 40000 something.
I tried 33333, both on PIX and VPN Conc. under Mode Config tab but still no use. Same error 412.

View 5 Replies View RelatedI manage a VPN 300 concentrator which has been happily working for several years without any problems. All users are part of the same group and authenticate to an RSA server. We recently moved from RSA authentication manager 6.1 to RSA authentication manager 7.1. Everthing continued working fine for several weeks, then at the beginning of this week we started getting users intermittently failing to connect to the VPN. I'm not sure if this problem relates to our new RSA server, but we have other network devices which authenticate to it with no problem so I guess the problem is with the VPN concentrator itself.
When users fail they just get a generic "Reason 427 connection terminated by peer" error message. The live event log shows "group = vpn, status = Not-in-service" when their connection fails. Other times they connect normally and no error messages are displayed. There seems to be no real pattern, sometimes your connection fails but if you keep trying you will eventually get in [however it can take many attempts over an hour or two before you succeed, or you may get in straight away with no problem].
I dont believe its a network problem, as I have run continuous pings to the concentrator and the RSA server whilst users are experiencing these problems and there are no drops.
The RSA servers authentication monitor always shows that the user has successfully authenticated, whether the users connection actually succeeds or not. I am tempted to just reboot the concentrator, but we have site-to-site VPN tunnels connected off it and I'm a little concerned that if it is faulty it may not come back up at all.
We recently had a Port Scan done on our external IP Addresses. One of those IP Addresses scanned was our Concentrator 3000. The report came back with the following TCP ports being open on the Concentrator 3000 - 80, 443, 1723, 10000, 10001, 10002, 10003, 10004, and 10009. I am unsure if it is necessary to have any or all of these open. The Concentrator 3000 is in front of our ASA5520.

View 2 Replies View RelatedWe are planning to use an ASA 5540 to terminate about 3000 IPSec connections. The maximum supported IPsec VPN Peers for this platform ist 5000, so this should be ok in theory.
What is a bit unclear to me is what exactly happens when (for whatever reason) all 3000 clients try to connect at once ? Perhaps it's not at once but depending on timers this could mean 3000 incoming IPsec connection within 10-20 seconds.
Will the the ASA cope with it ? I can't find any info regarding this on CCO. It's also not that easy to test/simulate.
We have a VPN router(ASA5505) which connects to the client, B. IP address for one si 195.xx.xx.xx and for B it is 14.xx.xx.xx. Both can extablish a IPSEC VPN nicely.Now, B throws a condition that the IP coming thru the VPN has to be PUblic. They want it as such so that they can be routed across the VPN tunnel.It still can because the firewall does not do NAT.

View 7 Replies View RelatedI have been tasked to install the first "hosted & managed" network setup at work. I've actually been tasked to clean this up, since one of the other engineers on my team botched the install. Here's my issue:
A small business customer ordered 4 VoIP phones/numbers, a T1 circuit, and a managed firewall service from my company. We provided them with Cisco 504s, T1 router with two Ethernet ports, a Layer 2 switch for their phones, and a Fortigate firewall to manage their network. They also wanted us to install & configure their Linksys wireless router for net access on their laptops and i Pads. The higher ups decided that V LANs were not an option, and they wanted to have the Voice and data on two separate Ethernet interfaces.
Here's the problem: In the initial work order our T1 router (an Adtran900 series - a reverse engineered Cisco OS) will connect the VoIP phones to the F0/0 interface (using the layer 2 switch) and act as the DHCP server, using Private IP adressing. In order to perform this, the first engineer enacted the Adtran's firewall, configured NAT, and setup an IP policy to allow the phones to communicate (allow any any basically). On the F0/1 interface, the firewall is connected. The Firewall is given a Public IP using the F0/1 address as the default gateway, and performs NAT to their internal data network. The problem is that outbound traffic works fine, and inbound/outbound works on the F0/0 interface where the phones are connected and the Adtran is performing NAT - but I cannot get access the firewall from the outside world. I know the issue has to do with the firewall on the Adtran router, and it trying to block inbound attempts to the public IP block assigned to the second interface. I attempted setup firewall rules to allow all traffic to that sub net and interface, but it did not work. As soon as I disabled the firewall feature on the main router, voila! - the Fortigate firewall was accessible from the outside world. But, this disabled their phones from working, as this disabled NAT for the private IPs for the phones.
Ideally I could use the switch and setup V LANs to segment the voice/data traffic, but that option was denied. I think the way we're doing this is over-complicated, but this is the desired configuration from my boss. He doesn't really understand V LANs and Firewall rules too well, so he wants the two interfaces approach. To make things even more complicated and redundant, I'll need to setup 1-to-1 NAT rules in the Fortinet firewall to allow access to the /29 we have allotted the client for their connections to Ford/GM/& Chrysler. I can't think of an efficient way to make this work - every scenario I come up with hits a roadblock. I've attached a network diagram so this can make some sense. The IPs have been changed.

I thought it could be VPN but then u still need a public facing ip , or can it be the fact that the public ip is router to nat and from nat to internet but then 10 range will need to be converted back to public which does not happen as from the private 10.10.10.10 it moves to the next router which is an isp device and not clients one?
I'm currently setting up two VPN 3000 Concentrators at two different sites to create a IPsec LAN-to-LAN Tunnel.

I'm trying to make a setup on my Cisco 881 router, but I'm having some trouble.I've managed to configure logging in with a Public-Private key pair over SSH, but it's also still possible to log in over SSH with just a username and password. I'd like to prevent this, if possible. I imagine I might have manually configured this to be allowed at some point, but I can't quite figure out how I did this, as no matter what I've tried to remove, it keeps allowing this option. I still need to be able to log in with a username, because I want users to have different privileges.
Once I've logged in using the Public-Private key, I don't automatically go into privilege mode, even though the user is configured with a privilege level. I'd like to configure that users that I've configured to use a certain privilege mode, automatically go into privilege mode without a password prompt. I know it did this before I started using the Public-Private key (or before I used AAA, which was configured around the same time), so I wondered if it's possible to do this still.
is it possible to set up a public and private password on a single router so that the public connection can be dissabled without having to turn off the private one?

I know you can have private and public wifi but the two routers have to be connected. I haven't talked to him about the fact that he needs to secure his router mainly because we never cross paths.
