Cisco VPN :: ASA 5520 Requires To Accept 2 VPNs From Different Devices
Jul 1, 2012
I use a cisco asa 5520 to terminate multiple site to site VPNs. Due to the configuration of a parteners network, i have had to install 2 routers into this parteners network, i have been supplied static private IP addresses for each router each router has a unidue LAN subnet which is the VPN's protected network.The partener use's PAT with only one public facing IP address.The VPNs are initiated from the parteners network using an IP sla ping.
Upon installing my first VPN router in the partenrs network, once NAT-T was enabled on the local ASA the VPN started working fine. After installing the second VPN router i tried installing the new config on to the ASA but via CSM, the ASA complains that it can not have 2 VPN's with the same peer address configured.
Actually I have to make a VPN between an 5520 ASA and a Cisco 887VA-K9 Router. Connected to ASA I have the outside interface, the inside-DMZ interface, the PCs interface and the VoIP interface. In the other site I will need to have a new subnet and a VoIP phone which I need to connect to the VoIP subnet in the other side in order to work with our CCM servers.I need two VPN established between ASA and 887 Router?
I have a cisco router 881 with advipservices running ios Version 15.2(4)M1 this router is a device that the user will connect company equipement with antivirus and such.is there a way I can force the ports like fe0 fe1 2 3 to accept only devices with specific mac addresses?if not, is there a way for me to apply an acl to vlanX to block everything that's not from these specific addresses?
I got a VPN request form from one of our partners. On my side I have one ASA 5520 running 8.0(3) On their form, It says that their endpoints are two boxes, sitting on different cities, It also says that there is only one encryption domain, (actually just one IP) that I need to speficy on the VPN setting. It looks like they mean that you could access the same encryption domain from any of the two Boxes in different cities. This is strange to me, since every time I have set up VPN before, each endpoint has their own encryption domains.I never seen two enpoints with the same encryption domain behind, so Im confused wether it might be a mistake on their part, or this is expected.
I am looking for a solution to block smart devices from connecting to our network via VPN. Our current VPN solution is ASA5520 and we are using Cisco ACS for user authentication. We use Cisco VPN client only, no anyconnect or SSL VPN. Management is looking for a way we can stop smart devices from using VPN clients to connect and only allow laptops/desktops to connect. Any way we can do this via ACS or another method?
I am putting an pre-labbed DMVPN Hub config onto a production 1841. We had to upgrade the IOS to support protection with NAT so the current IOS we're running is c1841-adventerprisek9-mz.124-25g.bin.I can paste the configuration in fine (via the tunnel interfaces) and the router accepts it however the 'show dmvpn', 'debug dmvpn' and other related commands don't work. I have checked the IOS feature navigator and it definitely shows that DMVPN phase 1 and 2 are supported in this image.
I have a pair of 5505s with an IPsec VPN between them. On the first 5505, I also have a user connecting to it via client based vpn. The user cannot access systems on the other side of the ipsec tunnel. That 5505 protects subnet a.b.c.d, the user is on subnet a.b.e.d which is not inclusive to a.b.c.d. First, am I correct in the assumption that I need to add the vpn network of a.b.e.d to the list of protected networks, and second if I change the list, does it drop and reset the ipsec vpn?
How much the CPU is impacted by SSL VPNs on Cisco ASA 5500's?I believe that the ASA offloads a lot of its encryption/decryption on a built in VPN accelerator rather than placing load on the main CPU. Is this correct?
According to the ASA 5520 specs - it can handle a throughput of up to 225Mbps of VPN traffic. Of course, it does not say whether this is SSL or IPSEC but I would like to understand what impact say 100Mbps of SSL VPN traffic would have on the main CPU.
We need this information to gauge whether an existing firewall has enough capacity to cope with existing load plus additional new SSL VPNs.
I've got a setup where we have a wireless connection coming in and using mikrotik router. We have multiple stores coming in via the wireless with a dmvpn.
The vpn's terminate on the cisco c870 and can be seen when running: show dmvpn.The cisco has a default route to the fibre router (10.0.0.252). The wireless router is the default gateway for the network. The failover from wireless to adsl fails. (due to the cisco routing traffic back to the wireless router when wireless fails)
If I change the default route on the cisco to dialer1, the failover works, but none of the vpn's connect. The Branches all have dynamic ip addresses. The HO has a static ip.
My goal: I want to achieve adsl failover for when the wireless goes down and still have the vpn's connected.
Can I have some sort of "Dynamic" route on the cisco. So when the vpn traffic comes in via wireless and hits the cisco, the vpn traffic can then go back out that way via the wireless router, but still have a default gateway on the dialer interface for failover?
I have been endlessly searching around online, and trying things on the firewall, and cant seem to find an answer to this problem. Its probably something really simple right under my nose! I am using an ASA 5510, which currently has a few seperate site-to-site VPN connections configured, which connect to other Cisco devices on clients networks.
I work from home, so also connect to our network using Remote Access VPN (any connect) to connect to the network at the data centre.
Just to be clear, here is my amazingly drawn network diagram:
[[my house]]-------------- <any connect VPN>------------[[ASA 5510 / Data centre]]-----------<site-to-site>-----------------[[Client network]]
The problem I am having, is that I cannot connect directly from my house to the client network, I need to RDP into some server in the data center, then from there I can see the Clients network. Is there routing to be setup somewhere? between VPN's? Ive looked into the routing options on the firewall and cant seem to find anything that works. I've searched for this and cant find answers, even some sources saying its impossible.
I have a Cisco Valet wifi router that works fine with my laptop and my computer that has a usb wifi adapter. The problem is that for some reason when I try to connect my moms computer to the router it can only connect to the guest router and when I try to connect to the regular router it just fails even when I use the correct password. I have tried uninstalling the driver and re-installing it for the usb wifi adapter for my moms computer (NetGear N150 USB Adapter) and its nothing works. Her computer by the way is an Acer Windows XP SP3 machine.
I just got Charter cable internet and decided to purchase my own cable modem instead of paying 5 dollars a month to rent one. I got a D-Link DCM-201. I know it is a little old but it was brand new/unused so I figured it would work out well. Ever since we got it hooked up every few hours we lose internet connectivity. The power, cable, and status lights are solid green and the Ethernet light is blinking green. The only fix I have found for this is to power cycle the modem. The problem is this happens about once every 4 hours...having to reset the router every few hours is making having cable internet a much more painful experience than it should be.
I just bought a Westell modem 6100 model online, and when I try to change the profile, I get a message saying: The server 192.168.1.1:80 requires a username and password. The server says: Modem Secure."
I'm currently trying to setup a Linksys SRW2048 switch.
The switch came with version 1.0.0 of the firmware (circa 2005), which worked fine with Google Chrome and Safari on OSX.
However, I recently upgraded to 1.2.2 (circa 2009), and the in-built web configuration page doesn't seem to work in anything except for IE6 or IE7.
Chrome and Safari give me a whole bunch of resource not available errors, and the page itself doesn't render properly at all:
Firefox also doesn't render it properly either:
It seems a bit strange on Linksys/Cisco's part that they'd release an updated firmware that meant their switch could only be used by Internet Explorer.
Or failing that, are there any known workarounds to get this to work with Chrome, Safari, Firefox - anything other than IE? Or anything on OSX or Linux?
Also, I heard that firmware 1.2.1 still works on non-IE browsers - any archives of older Linksys switch firmwares?
As indicated in the subject, wireless users are finding that it is either unattachable (shows up in the list but fails to attach) or if you manage to authenticate and get in, it's painfully slow or simply drops out. Security is WPA-PSK. Only noticed the issue after a couple of Windows 8 laptops came into the household, but the problem still seems to be there when they are off so not sure if they are connected in some way or not. Updated to the latest firmware - no change. Wired connections are fine and when it's initially restarted, so is the wireless, seems to happen sometime after wireless services are restarted. Only the one Wireless SSID, nothing fancy, max users around 5, all on laptops or the odd pad. I changed channels done narrow wide etc, (using mixed mode - some Wireless N laptops some Wireless B/G. Nothing seems to make any difference. No log entries until the Wireless system is restarted, doesn't require a reboot of the router, just a SUBMIT of the existing wireless settings to force it to restart.
I am fairly new to the Cisco world and aim to take my CCNA in the coming months.I am now working with a customer who has several Cisco 857 (UK PPPOA ADSL over POTS)The have sonicwall firewall VPN devices that needs to have one block of 8 static ip addreses from the ISP at each site.The current configurations use the network address on the VLAN interface use Static NAT to a private IP address to connect to port 23 on the VLAN interface. Why would you set up the router this way?,I thought that from a block of 8 IPs the first would be the network address the last the broadcas address, one for the router (on the VLAN interface) leaves 5 usable for the hosts attached to the ethernet ports on the VLAN.
I have a Cisco 877 ADSL router which won't let me play with my VPNs like I used to in pre-Cisco days.I have a VPN server which resides on the inside of the network which used to get it's L2TP as well as PPTP tunnels passed straight through the ADSL router. No problems there with the old router.Now I opened the relevant ports for both TCP and UDP on the 877, but VPN simply won't establish when trying to connect from the outside. Process of getting the 877 to stop wanting to take charge of things VPN and just pass them off to an inside server?
I need to VPN into my work from my laptop on the private side of the 877. This works fine until after authentication, then the VPN connection goes silent, no traffic going through. Works fine when for instance using my iphone hotspot to connect through from my laptop. It's only not working when the 877 is in the equation.
We have a corporate site with a Cisco ASA 5580 (8.1), a remote office with a Cisco ASA 5510 (8.2) with a L2L VPN to corporate. A vendor has a L2L VPN to the corporate ASA with access to the remote office across the VPNs (hairpinning). The corporate office accesses an application at the vendor on port 23. Everything is working with regards to the vendor accessing resources to the remote office and the corporate office accessing the application at the vendor. Our goal now is to restrict the vendor to port 23 from the corporate network and port 9100 to the remote office. On the corporate ASA I setup a VPN filter and applied to the vendor's L2L vpn but when I apply the filter (see below) all traffic stops to the vendor such as telnet.
I understand ip addressing and what a subnet is.But why is it sometimes I connect two things together,it always requires a subnet mask, and other times no? For example when I try to connect two computers together, it requires both IP and subnet mask.But if I use FTP software all it ask for is IP.Same thing when connecting to a website through their ip, doesn't require subnet.
I've been having this issue where my wireless network completely disappears from my computer and it requires a restart to fix.I know for a fact that it is not my modem/ISP as my iPad still connects just fine to the network.My network disappears about after 10-20 minutes of being logged on.
Shareport recognizes the printer only after resetting the DIR-825 router. I don't know if this is a Shareport issue or an issue with the DIR-825 disabling the USB port.This happens after there is no PC connected to the router for a number of hours such as overnight. I have 1 laptop and 1 desktop running Win 7 64-bit and 1 laptop running Win 7 32-bit. The desktop is connected directly to the router and the laptops connect via wifi. All PCs work perfectly when the DIR-825 is reset.This isn't a big issue but it's extremely annoying and shouldn't happen. I use a Cisco WAG320 in my office that has similar USB functionality and this never happens.
DIR-655(A3) 1.33NAb02_HNAP_beta I used to be able to send notifications on log full etc... When my ISP was still allowing outbound email w/opt out of block on port 25. This worked on my old DI-524, and used to work on my DIR-655.In an effort to clamp down on spam my ISP formerly SBC now AT&T began requiring SSL. Secure Authentication is not required. With the ever increasing concern for controlling spam DLink really needs to get in gear and provide the support customers need and back the efforts of ISP's to control spam. Otherwise it's wasted code occupying space. On that note if space is a concern, need space for the code ~ throw SecureSpot out !

On the Outgoing Server (SMTP) Settings window click Edit and verify:
# Server Name - displays smtp.att.yahoo.com. # Port - displays 465.
Note: When updating the secure server settings, check SSL checkbox first to update the port setting.
* Under Outgoing mail (SMTP), the box next to server requires a secure connection (SSL) is checked. This works flawlessly with Thunderbird and other mail clients therefore it is clearly a shortcoming of the firmware on the DIR-655 i.e. no SSL? This is totally inadequate.
So I have a server running Linux and am looking to add VPN functionality to my home network. I have OpenSSH running and it works great for tunneling and remote file transfers but doesn't quite get the job done.I would like to be able to map a network drive in Windows to my Linux box and understand a VPN could accomplish this, problem is I really don't know anything about Virtual Private Networking! I was hoping someone could explain to me the differences between SSH / VPNs and point me in the right direction towards configuring OpenVPN on my Linux box.
Currently, we have the AnyConnect client authenticating our users to our AD environment. All is working as desired. Now our Controll Agency is requiring a two step authentication for VPN access. Is it possible (and if so how do you do it) to also configure the AnyConnect client login to send a PIN to the AD usres registered Cell Phone and then require that PIN to be input to make complete the VPN login process?
We have 3 sf-300 series switches in Layer3 mode deployed in different offices. We have found that approximately every 2-3 months at all 3 locations users experience a serious reduction in bandwidth. Only after rebooting the cisco does the problem go away and we're okay for another few months. some setting/feature that may be contributing to this? We are only using several ports and 1 static route on each switch. We are not using any of the bells and whistles on the switch. 2 of the switches are using the original firmware, whereas the other is using the newest firmware. Maybe this is just what we should expect from a Small Business switch?
I have taken over a couple of LMS 3.2.0 standalone servers (two different networks). When I reboot them they tend to be slow coming back up (20-30 min). I"m thinking this may be due to the fact that LMS was reinstalled on both of them as I see an old CSCOpx folder (CSCOpx_old) as well as the current one. I assume that someone reinstalled and the registry may be dirty and service dependencies may be jacked up but honestly I don't know how this works for LMS and I haven't found much good info in the user guide for common services for service dependencies or registry keys in general.
Also, one of the servers never comes up fully on reboot or restart of the daemon manager. I troubleshot this and found that Tomcatmonitor and Apache are always down after reboot/restart. Tomcatmonitor says that it was shutdown by the administor in a pdshow and Apache says that it was never started. I have to go into the server and manually start these processes with a pdexec to get the application up.
I have one ASA 5510, a primary ISP (cable, the single public IP lives on the ASA), and a backup ISP (ADSL, separate router that hosts its single public IP). I use IP tracking to detect link down on the primary. When I pull the plug on the cable modem and go to "Route monitoring", I can see the ASA's default route is now the backup ISP default route.That conforms with [URL] Pings to 8.8.8.8 fail however, and when I do a packet trace the ASA complains about the dynamic nat rule that still points to the primary ISP's interface.Only when I change the existing dynamic NAT rule (on my inside interface) to use the backup ISP's pool (which is a single 192.168.x.y address) , does 8.8.8.8 reply to my pings. So it kinda works but it's not full auto . I can't add a second dynamic nat rule on the same inside interface, nor can I select 2 IP pools in a single dynamic nat rule.
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)
I'm having trouble setting up a second IPSec VPN tunnel on my Cisco ASA 5505 to another office. I was able to setup the first one with no problem through the ASDM, but have not been able to get the second one up.The IPSec tunnel is connecting to a WRVS4400N router at the other office. I tried debugging crypto isakmp, and crypto ipsec, but I'm getting nothing. Below is the config. Does something look wrong on my end? I also attached a screenshot of the parameters setup on the remote router.
