Routing through a VPN.

I was wondering if anyone knew a good article to explain via a VPN routing works.

If you a SSL VPN with transatlantic lines in it are the routing table

----------------------------------------------------------------------------------------

Route outside 0.0.0.0 0.0.0.0 204.90.21.1 1

Route within xxxx 255.255.255.255 172.18.0.1 1

Route inside 204.110.220.0 255.255.240.0 172.18.0.1 1

Route inside 204.110.250.0 255.255.255.0 172.18.0.1 1

The VPN works great, but I'm just wondeirng how it is possible to connect to the VPN

and then with successful ping 192.168.1.1 or 204.110.210.0 when there is no route in the route

table of the SAA.

Maybe I just don't understand how routing works by the VPN through ASA so to speak.

Well, basically once the VPN client creates a connection to the VPN server, if traffic matches to networks, pushed by the server, the traffic gets encrypted and sent to the peer it VPN using the default gateway to the client.

The VPN server or peer receives the packet unencrypts he then sends it to the printer.

The routing part works pretty all the only difference is that the package traverses encryped thruought Internet.

  • PIX: Dialin routing through a different VPN VPN

    Here's the scenario: I have 2 PIX firewall on various sites connected to the internet with public (PIX A and B PIX) IP addresses.

    There is a permanent VPN site to site between the two and there is a clear separation between subnets between the two sites (internal network behind PIX is 10.10.4.0/24 and the internal network behind PIX B 192.168.0.0/16).

    I created dialin VPDN access to PIX for laptops to dialin via VPN - it currently allows access to the subnet 10.10.4.0/24 without problem.

    Now - I need these users of portable computers, when connects via the VPN to PIX has to be able to access the other remote site and access the subnet 192.168.0.0/16 of routing through the VPN site to site of PIX B.

    Is this possible? I would be grateful to anyone who helps with that. Thank you...

    This is currently not possible on the PIX as the PIX will not route traffic back on the same interface, it is entered in the.

    This feature will be available in the upcoming v7.0 version, which is currently in beta, so look out for it and you're ready to go.

  • burned by another router through vpn

    Hello

    Here's the deal:

    RV042G <--------VPN------->ROUTER1 ROUTER2<---lan1--><---lan2--->

    I have a RV042G connected to a router '1' (LAN1) via a VPN. I have another ('2' for LAN2) router behind the local '1' with another network router (no bridge, a different IP address).

    For now, I PING the IP wan router "2" of the RV042G, but the distant RV042G, I can't access the devices behind the router '2' on LAN2. The opposite is true, the LAN2 I can ping all devices on any LAN included behind the VPN LAN

    On the RV042G, I put a static route to indicate that the IP address of the LAN '2' was available router WAN '2', but a traceroute always shows that I don't use the VPN and ask my gateway provider instead. The static route list does not show the road, that I put.

    At this point, I'm a little lost. What can I do to tell the RV that route to ROUTER2 is via the vpn and not my provider gateway?

    Thanks for any help (and sorry for my bad English)

    After reading this guide:

    http://www.Cisco.com/c/dam/en/us/TD/docs/routers/CSBR/rv0xx/administrati...

    ... take a look on page 110. Group "remote control" is where you would list the subnets that are accessible through the VPN. Currently this group must contain "LAN1", so you'll need to add "LAN2.

  • Should I wear to the front through a VPN

    I currently have a Cisco 1905 as my hub router, running v15.1 (4) M4. (192.168.1.0/24)

    This router has a static public IP address on interface GI0/0 and the internal address is enabled GI0/1 and we use NAT for Internet access.

    I have an ASA5505 (v8 (4)) Branch (192.168.12.0/24) connection to the router with EZVPN and the VPN is setup and works as it should.

    I can access the branch out of the hub and vice versa.

    I have a security camera in the branch that I can access through the VPN without problem.

    The problem occurs when I try to access the camera from the internet using port forwarding.

    We have several camera in the Office of hub that we access using via the following command port forwarding

    IP nat inside source static tcp 192.168.1.40 80 40001-stretch SDM_RMAP_1 route map

    It works 100%

    I tried to access the camera in the Office using the command

    IP nat inside source static tcp 192.168.12.40 80 41001-stretch SDM_RMAP_1 route map

    but I can't get through.

    I can see the NAT translation in the branch for the port 41001, but I'm not through.

    Is this possible? should I wear to the front in a VPN tunnel?

    The problems is that the branch office is an Office suite and we rent space. We are not provided a public ip address and I have no control over the router providing an address in the ASA5505.

    Any help would be appreciated thanks

    If you have crypto-cards running and you prefer split tunneling, then I suggest a completely different way to resolve that:

    You can install a small linux box (or Win2012R2 will also do the job) in the main exercise (better would an own DMZ for that) and set up as an agent reverse. This system takes requests and passes them to the cameras.

    I need to do a port forwarding on my router. My internet connection works (even if she falls occasionally) and I can also connect to other computers on my network.

  • AAA authentication for external router through PIX 515

    I have been in vain, to get the authentication AAA works to my external router, through the PIX.

    When I connect the router directly within that network (bypassing the PIX) AAA works fine, so I know the configuration of the AAA works between the router and the ACS server.

    Initially, I got the PIX configured with a static map between a global external address 192.x.x.12 and a 10.200.1.187 for the ACS server local address, but that didn't work either. So, currently I am using NAT exemption for the ACS server, but it does not work either.

    If I activate the debug on the PIX package, I see the ACS authentication request and response between the router and GBA when I try to connect to the router, but it is not successful. After the three way TCP handshake, the router repeats it is last receipt, and then the ACS asked an RST.

    The attached diagram shows the simple connection that I'm trying to create.

    The configuration of the PIX is also attached. (too large messages size):

    Thanks in advance for your help. I tried EAC for two days and have not found solutions that look like this.

    Ron Buchalski

    What to do is:

    1 PIX:

    -static map the ACS/GANYMEDE to a public IP address

    static (inside, outside) x.x.x.10 10.1.1.25 netmask 255.255.255.255

    -otherwise, if you have enough public IP, use the port forwarding for card IP ACS to PIX outside IP of the interface, IE x.x.x.2, via a specific TCP 49:

    public static tcp (indoor, outdoor) interface 49 10.1.1.25 49 netmask 255.255.255.255

    * allow ACS talk to external router via public IP

    Create/add entry for ACL applied to the outside interface to allow the GANYMEDE Protocol + switch router external to the ACS:

    access outside permit tcp host XXX1 host x.x.x.10 eq 49 list (Ganymede + use tcp 49)

    outside access-group in external interface

    * x.x.x.1 = outside the router

    2 ACS

    -Add the outside router IP (FastEthernet face PIX outside interface) interface as a client of the AAA

    -Making of course secret key is identical at ACS and router

    3. the outside router

    -Add the ACS as radius-server using its IP public, as mapped in PIX which is x.x.x.10.

    -check the key AAA statement is accurate.

    The test without saving the config is outside the router. Save ok once confirmed.

    I have similar facility before, and it worked very well.

    Pls note all useful message (s)

  • An ASA inspect traffic through a VPN?

    The ASA did inspect the traffic through a VPN using the default inspect the rules?

    Hi Justin,

    The SAA can inspect traffic encryption before or after decryption. The ASA cannot inspect encrypted traffic.

    This means that if the VPN tunnel ends on the ASA, ASA can inspect traffic sent through the prior encryption tunnel and could inspect the traffic post decryption when received.

    If the tunnel is not over on the SAA but pass instead through the ASA, ASA cannot inspect traffic encapsulated inside.

    It will be useful.

  • SA520w routing through site-to-site VPN tunnels

    I have several offices that are connected using site-to-site VPN tunnels and all will use the SA520W (firmware 2.1.18). I currently have 3 routers in place, router tunnels created for the router B and c of router. I need assistance with the configuration to allow the guests to router site B get to the router site C. I have attempted to add a static route, but get a destination unreachable host trying to ping. Also, if I connect to the router site has via the Cisco VPN client, I'm not able to get resources on each site, B, or C.

    A - the site 10.10.0.0/24

    Site B - 10.0.0.0/24

    Site of the C - 10.25.0.0/24

    Any help is greatly appreciated.

    So, that's what you have configured correctly?

    RTR_A

    ||

    _____________ || ___________

    ||                                            ||

    RTR_B                                RTR_C

    Since there is no tunnel between B and C there is no way for us past that traffic through RTR_A for two reasons. The most important reason is that subnet 10.25.0.0/24 (rtr_c) is not allowed to pass through the IPSec tunnel (it's okay to IPSec?) of rtr_a ==> rtr_b. You can't just add a statement of road because your addresses are not routable which is the reason why it fails.

    Your only option is to create another tunnel between rtr_b and rtr_c. This may not be the ONLY option, but you should get what you need.

    I hope this helps.

  • Configuration of the router to allow VPN traffic through

    I would like to ask for assistance with a specific configuration to allow VPN traffic through a router from 1721.

    The network configuration is the following:

    Internet - Cisco 1721 - Cisco PIX 506th - LAN

    Remote clients connect from the internet by using the Cisco VPN client. The 1721 should just pass the packets through to the PIX, which is 192.168.0.2. Inside of the interface of the router is 192.168.0.1.

    The pix was originally configured with a public ip address and has been tested to work well to authenticate VPN connections and passing traffic in the local network. Then, the external ip address was changed to 192.168.0.2 and the router behind.

    The 1721 is configured with an ADSL connection, with fall-over automatic for an asynchronous connection. This configuration does not work well, and in the local network, users have normal internet access. I added lists of access for udp, esp and the traffic of the ahp.

    Cisco VPN clients receive an error indicating that the remote control is not responding.

    I have attached the router for reference, and any help would be greatly apreciated.

    Manual.

    Brian

    For VPN clients reach the PIX to complete their VPN the PIX needs to an address that is accessible from the outside where the customers are. When the PIX was a public address was obviously easy for guests to reach the PIX. When you give the PIX one address private, then he must make a translation. And this becomes a problem if the translation is dynamic.

    You have provided a static translation that is what is needed. But you have restricted the TCP 3389. I don't know why you restricted it in this way. What is supposed to happen for ISAKMP and ESP, AHP traffic? How is it to be translated?

    If there is not a static translation for ISAKMP traffic, ESP and AHP so clients don't know how to reach the server. Which brings me to the question of what the address is configured in the client to the server?

  • PPTP VPN Cisco IOS router through

    Hi all

    I was wondering if there is a trick to get PPTP to work through a Cisco router.  He was in fact at some point, but I don't remember what has been changed over time... However, it no longer works.

    Current configuration includes:

    * CBAC applied inbound and outbound on the Internet interface (I needed to add incoming to fix a problem with the mode passive FTP doesn't work is not on a FTP server hosted behind this router)

    * CBAC inspects, among other things, PPTP

    * ACL applied inbound on interface Internet, GRE and TCP 1723 admitted any intellectual property

    * No other ACL on the router

    * IOS 15.0 (1)

    * Inbound configuration NAT for TCP 1723 (currently using the WAN IP address)

    One thing I saw was so Troubleshooting "IKE Dispatcher: IKEv2 version detected 2, Dropping package! - but I think that it is a wrong journal (router as the Cisco VPN configuration example).

    The server is definitely okay - we are able to connect over PPTP VPN from the local network to the server.  So I think it's a sort of NAT problem, because I don't see anything dropped by the firewall.

    Anyone able to point me in the right direction?

    Thank you

    Hello

    Thanks for fix the "sh run". Could you change the following:

    IP nat inside source static tcp 10.77.99.11 1723 1723 road-map repeating sheep ccc.ccc.ccc.ccc

    to do this:

    IP nat inside source static tcp 10.77.99.11 1723 1723 extensible ccc.ccc.ccc.ccc

    It would be prudent to proceed with this change in the removal of the map of the route if no one connects to the server via the PPTP VPN.

    Let me know.

  • SGE2010 customers have need to route through ASA 5505 &amp; 3750

    Please see the included diagram.

    I need to move out of the 3750 client machines (and DHCP dependence on it) to the SGE2010 and absolutely to carry their internet traffic on through the external interface on the 5505. They must also be able to communicate in the internal environment to communicate with the production servers.

    Customers use actuellement.254 speaking through a silent dell in the 3750 switch, but I'm trying to migrate more slowly at la.253. I know that the 2010 will not DHCP, so I put a DHCP server on this switch now. The 5505 will not let me add a statement additional nameif on one of the other eth0 / x interfaces and I don't know if this has something to do with its capacity to act as a DHCP server (it is not an option in the ASDM) or he has ability to use internet gateway for customers in 2010. (Quick notes: The 5505 has a base license and is currently also site to 1 VPN connection.) As the 5520, then all its interfaces are used as well).

    I have statically assigned a customer moved with an adresse.253 and plugged into the 2010. I tried to give the 2010 both an adresse.4 and an adresse.253 but neither will allow me to ping on the 5505 addresses. The 2010 auto shows routes to two subnets and I put its default route to 253.1.

    The link between 2010 and the 3750 works - clients receive an adresse.254 of the 3750 and can get out to the internet via the 5505 and reach as well production servers.

    Why don't the 2010 see the 5505 as a gateway and allow customers to access the internet and also browse the 3750 when they need to access the production network?

    Now, the key to monkey. The reason why I am not "just connect both cheating and call a day is because I need also Always go out production servers / web applications via the interface of 5520 out outside/inside."

    I have such a package of wire trouble my head around why I can't get my customers moved to the new switch, I have not yet figured out how I'll do it again.

    Any help would be greatly appreciated.

    Scott

    Hi Scott,.

    OK, you'll have several IP networks connected on the SGE2010... that's fine that the switch can operate in Layer 3 mode.

    But the ASA5505 or the SGE2010 may only be granted to PC customers who are hooked the switch SGE2010 default gateway ports?

    If the SGE2010 is made the default gateway for the PC clients, the SGE2010 will go to layer 3 packets between appropriate subnets.

    (depending on whether you have added a few static routes inside your SGE2010)

    If the SAA is the gateway to the host PC, the ASA will route traffic accordingly.
