I'm looking to put together a solution for a customer that wants to "bridge" between their current office and a new office space they have rented. I know how to set up a site-to-site VPN between two sites with different private IP ranges. For example, site A is 192.168.1.0/24 and site B is 192.168.2.0/24. But is it possible to make both sites appear as a single IP block? This way, systems could be moved one by one without renumbering.I am guessing there might be a way to tunnel the layer 2 traffic and make it work, but I am concerned about broadcast services being broken. I am using non-cisco platforms so I am just looking for pointers on the protocols that might be used so I can do further research.
I would like to know if there is a possibility to create 2 Remote access VPNs for 2 ASA situated in different sites and using only one PCF file.Is set up a tunnel between the 2 ASA the only way to reach the 2 destinations with the same PCF file?
We have a Main ASA 5520 and two remote site ASA 5505's that connect to each other via S2S VPN tunnels. Currently they are doing split tunneling, so only local traffic goes over the tunnel. We have are local LAN (10.0.0.0/16) and our DMZ (10.3.0.0/24) network at the main site. The DMZ hosts our external sharepoint, but we have access to it internally The problem is site A (10.1.0.0/24) and site B (10.2.0.0/24) have no idea of it, and when attempting to go to the site, it fails. You can access it via the external site address, but that's the only way. Normally the external address is blocked when you are internal.What i'm stuck at is even when we had all traffic sent from Site A to our main hub, it still wouldn't find it. Would i have to make a separate vpn tunnel purely for that DMZ traffic?
I have inherited a sbs 2008 network where they have a SBS2008 server and Server2008 running as a terminal sever at the main office and they have 2 satellite offices. These offices all connect through router to router vpn tunnels. The main site is on 10.0.0 and dhcp is done by the sbs. Satellite site a is on 10.0.10 and dhcp is done by the vpn router and Satellite site b is on 10.0.5 and dhcp is also done by the vpn router. All client computers can run rdp to access shares / programs etc on the two servers but when trying to push out group policy, antivirus updates or even using remote control through the SBS2008 server it is hit or miss. DHCP records on the SBS server do not seem to update correctly, manually changing the ip address in DNS records results in warnings that the PTR record cannot be created.
So I am wondering if the configuration they currently have setup is correct. What might be stopping some but not all computers from updating, why I can connect to some but not all computers at site "a" but I am not able to remotely connect to any computers at site "b".Why I can do remote installs of Eset Endpoint Security on roughly 10% of the clients but the other 90% fail.
I would like to understand how public IP works in remote access. I do have belkin router and when I access it remote I type my public IP and after it the port number for example xxx.xxx.xxx.xxx:80 and if I would like to access an IP cam remotely in the same network i would do the same thing xxx.xxx.xxx.xxx:5656 (public IP). I do know my Public IP is unique.Thus, its quite logical I can access my devices remotely. my understanding of the port number is application specific that addresses packets in different applications in the same computer. For example port 80 is for HTTP connection used browsing the web, for chatting in MSN i will use different port number specifically for MSN...etc. my question is how I can access my belkin router remotely by typing the public IP and the port number knowing that the port number is application specific not device specific? My second question is, is it possible to access two routers in the same network remotely?
I have been asked to setup wireless and we have purchased WLC 5508 and 1142 APs.We have several remote sites and a centralized WLC. The requirement are to have a common SSID (Corporate) advertised across all the remote sites and have that SSID locally switched, and have another two SSID Guest and Mobile tunneled back to the central site (WLC).I want all the wireless (Corporate) clients to use the same subnet as the wired clients at each remote site, the IP assigment will be done by a DHCP server at the central site. The Guest and Mobile users will use a common subnet each across all the site and this will also be handled by the DHCP server at the central site.
I have enabled H-REAP with Centralized Authentication and Local switching but I'm not sure about the second part which is to have a common SSID (Corporate) across the remote sites and localy switched whilst having the other two SSIDs tunneled back to the WLC. Cisco TAC told me to configure dynamic interfaces for each of the remote site but then he said I still wouldn't be able to switch the Corporate traffic localy if I use a different subnet to the wired subnet for the wireless clients.
I am installing 2 ASA 5505s at home offices with dynamic IPs. The EasyVPN server is a ASA585x. I am using the 5505s in NEM mode. I configured a unique DHCP scope on each 5505. I have a dynamic crpto map on the server. I configured unique tunnel groups, group policies and usernames for each site on the server. This seems to work fine. Is it normal to configure unique tunnel groups, group policies and usernames for each remote site?
We have a Cisco 2921 router at the head office (Easy VPN Server) and been deploying Cisco 887VA (EasyVPN remote - Network Extension) for remote offices using EasyVPN. We are allowing Voice and Data traffic over VPN. Everything has been working great until this issue was discovered today:
When a remote user behind Cisco 887VA calls another remote user also behind Cisco 887VA, the call connects and Avaya IP phone rings but no voice in either direction.
Calls to/from head office and external mobiles/landlines are fine. Only calls between two remote sites are affected. As there is no need for DATA connection between Remote office, our only concern is Voice support.
I think "hair-pinning" of traffic over VPN interface is needed. (Examples configs etc).
I have got two 878 integrated services routers and I need to configure them as transparent bridges in order to connect 2 remote sites over ATM.
As I'm testing the topology, I configured two switches (representing the sites) at each end with a VTP domain. VTP works while the switches are connected directly with eachother, but it won't work with the bridges in the middle. [code]
I have been working with my ASA 5505 VPN Concentrator to maintain a connection with one of my remote sites. I have several tunnels that work fine and dont have any issues at all, but one tunnel with outside IP ending in 146 and inside LAN 192.168.3.0 goes down every 24 hours. Attached is the config from the concentrator. I changed around the Security Association Lifetime Settings and the tunnel would drop after that amount of time expired. If I set it to 24 hours, the tunnel would drop every 24 hours. If I set it to 8 hours it would go down every 8 hours.
I have swapped the router a few times, double and triple checked my key settings, disabled keep alives on both ends, and this problem just started happening a few weeks ago after working fine for years. I also get the following e-mail error every time it goes down:
<161>Jul 10 2011 16:19:47: %ASA-1-713900: Group = xxx.xxx.xxx.146, IP = xxx.xxx.xxx.146, construct_ipsec_delete(): No SPI to identify Phase 2 SA!
5 - Remote sites (no static IP there) 3 - Remote users (comercial) 1 - Central building (using static ip address)
Is it possible to establish a permanent vpn tunnel between each one of my remote sites to the main building, even if I have no static IP address in the remote sites?
Do you think that RV180 is the best choice to mannage vpn connection between remote sites and the central building securely and faster?
for example, there are 3 sites, A, B and C. A and B are 1.5 km apart and both are separate LAN(mixture of wireless and wired). C is 35 km apart from A and B. I have to connect A, B and C so that they can communicate with each other. Security is required.
MY ISP installed one router in my lab.for internet connectivity they mail me steps :connect your Laptop directly to gi0/3 port to check internet connectivity with public ip 1.1.1.x and Gateway 1.1.1.1 with subnet mask 255.255.255.240 after connection I surprised because I am able to access only google sites like gmail,google search etc. but I am able to ping/traceroute all sites.from browser I am able to access only google sites only.In Router no firewall no such access list.
We have two ASA 5500 series Firewalls running 8.4(1). One in New York, another in Atlanta.They are configured identically for simple IPSecV1 remote access for clients. Authentication is performed by an Radius server local to each site.
There are multiple IPSec Site-to-Site tunnels on these ASA's as well but those are not affected by the issues we're having.First, let me start with the famous last words, NOTHING WAS CHANGED.
All of a sudden, we were getting reports of remote users to the Atlanta ASA timing out when trying to bring up the tunnel. They would get prompted for their ID/Password, then nothing until it times out.Sames users going to the NY ASA are fine.After extensive troubleshooting, here is what I've discovered. Remote clients will authenticate fine to the Atlanta Firewall ONLY IF THEY ARE USING A WIRED CONNECTION.
If they are using the wireless adapter for their client machine, they will get stuck trying to login to Atlanta.These same clients will get into the New York ASA with no problems using wired or wireless connections.Windows 7 clients use the Shrewsoft VPN client and Mac clients use the Cisco VPN client. They BOTH BEHAVE the same way and fail to connect to the Atlanta ASA if they use their wireless adapter to initiate the connection.
Using myself as an example.
1. On my home Win 7 laptop using wireless, I can connect to the NY ASA with no issues.
2. The same creditials USED to work for Atlanta as well but have now stopped working. I get stuck until it times out.
3. I run a wire from my laptop to the FiOS router, then try again using the same credentials to Atlanta and I get RIGHT IN.
This makes absolutely no sense to me. Why would the far end of the cloud care if I have a wired or wireless network adapter? I should just be an IP address right? Again, this is beyond my scope of knowledge.We've rebuilt and moved the Radius server to another host in Atlanta in our attempts to troubleshoot to no avail. We've also rebooted the Atlanta Firewall and nothing changed.
We've tried all sorts of remote client combinations. Wireless Internet access points from different carriers (Clear, Verizon, Sprint) all exhibit the same behavior. Once I plug the laptops into a wired connection, BAM, they work connecting to Atlanta. The New York ASA is fine for wired and wireless connections. Same with some other remote office locations that we have.
Below I've detailed the syslog sequence on the Atlanta ASA for both a working wired remote connection and a failed wireless connection. At first we thought the AAA/Radius server was rejecting us but is shows the same reject message for the working connection. Again, both MAC and Windows clients show the same sequence.Where the connection fails is the "IKE Phase 1" process.

On wireless (lenovo tabletx61) I cannot connect through the intranet - no problem connecting through internet. When I manage to connect through intranet connection is dropped quite often.No problem connecting via Ethernet cables.
my private ip add is been hacked by someone, I have chk from various sites but the host name is unavailable so pls let me know how to get the host name of that pc & how can i get my ip 10.62.11.33 back to my org
how the address stops at 31 in the second octet. I'm not even completely sure how it starts at 16 for the first address (172.16.0.0). are we dealing with subnets?
Is it possible to use 1 private IP through VPN and same private IP mapped with Public IP? For example 192.168.0.1 is configured in VPN tunnel. i m able to ssh on both ends. ( VPN phase 1 and phase 2 gets completed)But when i map 192.168.0.1 with some public IP problem starts. when i try ssh i see public IP in my destination firewall logs. IPSEC: Received an ESP packet xx.xx.xx.xx "mapped public IP". The decapsulated inner packet doesn't match the negotiated policy in the SA, The packet specifies its destination as
i recently get high speed link for my compagny to replace the old frame realy.the internet service provider gave me a non routable range to set on my asa like this : [code]then the ISP tell my public ip wan range was x4.23.209.166/29.i made this kind of configuration works when i put a cisco routeur in befor the cisco asa like this: [code] it is possible to make this works on cisco asa 5510 without putting a router in front ?if it works problem can happen to establishing vpn from the outside interface having a private ip ?
I have a server with IP address 10.10.10.10/24. I have two ISPs and their public IP address subnets are 1.1.1.0/25 and 2.2.2.0/25. The gateways are ASA 8.0 and ASA 8.4.I am getting rid of the 1.1.1.0/25 ISP. However I will need the Internet users to be able to access the server via both ISPs at the same time.The only way I can think of is to do policy based dynamic PAT so the Internet user IPs will be translated into an internal IP. Idealy, users connecting on 1.1.1.10 will be PAT to 10.1.1.10 and users connecting to 2.2.2.10 will be PAT to 10.2.2.10. When the server responds to them, it will then route to the correct ASA..
we have one OC-24 private line between our data centers. we are looking to get best throughput but we get max. avg throughput of 300Mbps with peaks of 800Mbps throughput. i.e. we transfered 2TB of data over this link and we got average throughput of 300Mbps with peaks of 800Mbps.
we should at least be getting 800Mbps throughput since we have OC-24 (1244Mbps) private line. we contacted our ISP but they said there isn't any problem in private line from ISP side. what can we do to increase average throughput?
We have some Cisco 2911's that we are configuring 2 VPN's ( second is for redundancy) We are pretty confident on the failover VPN setup using SLA monitoring.
One thing we are stuck on is the redundant VPN will be setup over a 3G connection provided by verizon. Verizon issues a Private IP ( 192.168.100.X) the far end device terminating the VPN has a public ip of 183.172.22.XX , what kind of NAT translation do I need to make this work ? Also does Cisco have any good configuration examples for VPN Failover setups for Cisco 2911's?
I have my SSL server certficate on my old acs 3.3.along with private key file , How i can export this private file with .pem extension from windows 2000 server , This private key file is not identified under certificate mmc console , Because my acs application is being installed on a separate hardisk partition under D drive .
file path : d:Certificatesh02cacsw02.pem
how i can export this.pem from that particular folder
I have a router, networking 2 computers. One of them I wish to set to "ad-hoc" I do not want it accessing the internet.
So, a "wired ad-hoc".
The best discriptsion I have is on a Vista or 7 machine you have the Network map I want to disconect the computer from the internet, and leave it connected to the network.
I have a IBM T23 laptop that I have reformatted and am trying to log onto my wireless internet via a linksys pcmcia card which When I try to connect it tells me I have private IP address and I am not sure how I can reconfig so that I can connect via my router to the internet.
I have two Win XP machines. One is connected to the LAN and the other is a standalone. I have installed an additional network card on the machine connected to the LAN. That machine is linked to the standalone through a switch using the 162.198.1.xxx sequence of IPs, with 255.255.255.0 as the subnet mask and no DNSWINS, or anything else. I can ping either machine from the other through the private network, but cannot see the files. I need to pull certain files from the standalone, but have not been able to even see them.
I want to add server(Intel PC with 2.8 P4 processor, 1GB RAM and 80GB harddisk) to my private network (not accessible from outside).I have 50 users in my network ( approximately 30 users login at same time)what simple good things that I could have on the server( website, forum,...) and what OS should I install on it?
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.
I'm tryig to put a computer into the DMZ and then access it from computers on the LAN using a local IP address. My reason for doing this is that I'd like my DMZ computer to be a locked down web server (just ports 80 and 443 open to the outside), but I need to be able to have more access to it from inside my LAN (e.g. I want to be able to SSH into it from the LAN).
Thus far I've been able to get a computer set up in the DMZ and can access the Internet from the DMZ computer. And I can access the DMZ computer from the LAN computers using the public address for the DMZ computer. But I can't access the DMZ computer from the LAN computers using a private address for the DMZ computer. see the attached file for a diagram of our current settings. A few descriptions:
- Verizon provides us with a number of static IP addresses, i.e. 71.123.123.10-12 (note these aren't actually the addresses, but representative).
-- In the RV042, I have the following configurations made: - Setup > Network > LAN Setting - Device IP Address = 10.4.20.1
I am now using ASA 5510 as a firewall device.I have configured 3 interfaces ethernet 0/0,ethernet 0/1,ethernet 0/2 as Wan interface, DMZ interface and Internal Lan interface. Internet is working fine from LAN as well as DMZ.The WAN interface use the Public Point 2 point IP(/30) Provided by the ISP and another pool of Public Ip is also provided by the ISP (/28). Now I want to Map the /28 IP to some servers in DMZ . DMZ servers currently have 192.168.101.0/27 private IP . Now the problem is how to Map the Public IP to those Private IP in DMZ servers.
My partner imposes that i create a VPN connexion with CISCO ASA5505 and send requests by public IP on my private network.Is it possible to create NAT rules with this possibility?
i have two cisco 2800 routers , and i have three different networks , so can cisco routers supports more than one private network example,My First location i have one public connection of 200.100.100. 1 and private network of 192.168.1.x network and the second router i have one public connection of 200.100.100.10 and two private networks of 192.168.50.x and 192.168.60.x , So can i route my first location to this two different networks , because my router have only two FastEthernet connection , so how it's possible or not.
