PIX stops passing all traffic at the entrance to command crypto

I have a strange problem with a PIX 515 6.1 (2).

I have 3 VPN tunnels already implemented. While trying to set up a 4th the PIX stops passing all traffic. He arrives precisely when I enter ANY command "crypto map.

cancellation of the order by using "no card crypto...". ' or "clear xlate" is no help either. The PIX must be restarted before the traffic going on again. The CPU usage drops to zero and my telnet for the PIX session remains connected.

Anyone have any ideas?

I put the relevant configuration below:

Hi Ishaq,

Please make sure you remove the card "Crypto" off the coast of the Interface by doing a ' no card crypto toVPNs no interface out ' and then add the necessary commands before reconnecting the Crypto map. Usually when we add a new command "toVPNs xx ipsec-isakmp crypto map" without removing the Crypto Card it starts encrypt all traffic passing through the PIX. After you make the required changes, reapply card Cryptography.

Hope this helps,

Kind regards

  • Send all traffic through the vpn tunnel

    Does anyone know how to send all traffic through the tunnel vpn on both sides?  I have a server EZVpn on one side and one EZVpn client on the other.  I'm not natting on each side.  I use the value default 'tunnelall' for the attributes of group policy.  On the client side all traffic, even if not intended for the subnet of the side server, seems to pass through the tunnel.  But if I ping the side server, the same rules don't seem to apply.  Traffic destined for rates aside customer through the tunnel, but the traffic that is not pumped on the external interface in the clear.  That's not cool.

    Hello

    Clinet traffic to server through tunnel, that's right, right?

    Traffic from server to client through tunnel, but the rest of the traffic is not, no?

    This works as expected because in ezvpn, politics of "tunnel all ' is for traffic is coming from the client., do not leave the server.

    Side server, customer traffic will pass through tunnel, the rest used.

  • Tunnel of RV042 V3 that routes all traffic to the VPN

    Hi all

    I use Cisco Linksys RV-042 with V2 hardware to set up a VPN tunnel that route all traffic to the remote gateway (a Cisco ASA 5510). This configuration works very well, and I can access the local router and other resources to the central site.

    I'm doing the same thing with Cisco RV042 with version V3 of the material, but I can't access the local router until the VPN breaks down. I can ' ping, SNMP the local router, or access but I can access the central site. Very strange.

    Do you know what can I do to access the router local (for example, hardware V2) with connected VPN?

    Thank you

    Rafael

    Just a hunch, but in the remote network you agree with what the network and subnet?

    I've seen this symptom before.

    LAN on the RV series.

    10.10.2.0 255.255.255.0

    Trust remote networks

    10.10.1.0 255.255.248.0

    It is traffic destined to the router on the 10.10.2.1 ip address is through the tunnel forward. So, for this purpose, you can only access the router LAN interface when the tunnel is out of service. I'm not sure why ping works but it does. I'm looking into this symptom on a different device, but the device has a similar graphical interface.

    I would like to know if you have a similar setup.

    My mail server and FTP servers have adjustments because of the anti-hammering problem this creates.

    Has anyone seen this problem and know of a fix for this?

    @Cisco... Before you suggest that I have to call tech support, I already have. I just had the race and they told me to call level 2 support and do not provide me with a phone number. For some reason, he refused to escalate the call. He simply told me to contact a person of a previous issue, in which they gave me the beta firmware to download and I spent a lot of time on the phone to get there. I don't want to talk to the same person who spoke to my last question.

    Yes, I have seen this problem and reported it. Should have the Bug ID CSCue49377, but I can't verify this, because I don't have access to the bugs database.

  • Software exists for the creation of a 'virtual' network card and going to all the traffic on the local network through a proxy server, then by this adapter?

    I can access net through LAN and my college requires a proxy for all access to the internet. If you want to use the internet, it is impossible to do not use a proxy. This is a problem for many programs that do not seem to allow you to enter the proxy settings.

    any software is to create a 'virtual' network adapter that will pass all traffic network (or any protocol x traffic) through the proxy?

    So I have do not need to enter the proxy anywhere... and I have normal internet access.
    What I saw is possible with OpenVPN, but it is a vpn service that I need .i just want to use the feature. In OpenVPN I just enter my proxy server in its framework and OpenVPN to connect to a VPN service and routes all traffic to the FAUCET adapter after which I don't need to set the proxy address anywhere... so my idea is how can I use only the last part that is routing all my LAN traffic to a virtual card.

    Support the LAN---> proxy---> virtual adapter--->, then software I access the net

    That's what I like to do...

    Although I am facing this problem on Windows 7, solutions for all operating systems are welcome.

    P.S: Proxifier is not my solution to not offer something like this.

  • PIX 515 no traffic on the new IP address don't block

    We have received a new range of ips 213.x.x.x/28 from our ISP. They are routed through our existing entry door 92.x.x.146.

    The problem:
    We can not all traffic to the pix on the new 213.x.x.x/28 range.
    -If we try to ping 213.x.x.61, we get the lifetime exceeded.
    -ISP Gets the same thing of their router.
    -ISP tries ssh and gets no route to host.

    The ISP has ticked then double the Routing and the MAC address of our external interface. They are correct.

    The strange thing is that we cannot see THE log messages about the new range of incoming connection attempts. The Pix is running at the level of the journal 7.

    Does anyone have an idea what could be the problem? or suggestions for debugging the issue?

    ...we are sending this correctly to your pix, you should see any traffic destined for a 213.x.x.0/28 address hit your interface at 92.x.x.146/32

    Yes 217.x.x.81 and 217.x.x.82 are routers owned by our ISP.

    Is there anything else I can ask the ISP in terms of testing/debugging? I've run out of ideas.

    If the routers are owned by your ISP, then the fault lies with them. They have a routing loop in their network and that's why packages are not your firewall. You have them shown the traceroute?

    They must focus on the routeurs.81 et.82 to establish why the packets are looped between these 2 routers. Until they fix this packet will never get your firewall.

  • Send all VPN traffic and the other end it blocks Internet

    Hello

    I wonder if I can get a RV042 VPN Tunnel to a RV082 and in the RV082 block all traffic on the internet that comes form the computers that are behind the RV042.

    Something like this:

    Remote PC-> RV042-> VPN-> RV082-> firewall RV082 (block internet traffic, allow intranet traffic)

    Thank you very much

    Oliver

    The scenario you describe should be doable with a pair of RV042 and RV082, where all traffic is transmitted by RV042 to RV082. What you need is to configure an access on RV082 rule to deny the RV042 subnet HTTP traffic to ALL (internet).

  • Force traffic into the tunnel?

    No IPSEC applied anywhere yet.

    If you have 2 routers configured back to back with the physical interfaces tunnel interfaces - which way will be the traffic travels above?

    Answer - It will follow the path of the routing table that I guess. OSPF or static or other routes.

    Series enough.

    Now add one IPSEC.

    OSPF fails as IPSEC does not support multicast.

    Series enough.

    Now, add IPSEC and GRE to the mix. Apply card crypto both physical and tunnel interfaces.

    Included here is the common ACL associated with free WILL. That is: -.

    access-list 100 permit will host [address physical source] [address physical destination]

    It's the ACL that is supposed to define what traffic is 'interesting' and which must be encrypted.

    We will repeat the question: what should be the traffic?

    I guess it's the same answer. Refer to the routing table.

    But that traffic is encrypted? Answer - ONLY traffic destined to the IP tunnel interface.

    If you ping from physics to physics, it will be clear.

    Question - do you need to force ALL traffic to the bottom of the tunnel interface in the order so he could match the ACL and therefore get encrypted?

    How do accomplish us this?

    Discussion and debate would be greatly appreciated.

    He

    Only traffic with the source/destination of the tunnel interfaces - you just encapsulate & encrypt what happens / leaves the tunnel. If you have two sites connected through a VPN IPSEC, 'interesting' traffic for VPN is the source/destination on tunnel interfaces you need to LAN traffic in the tunnel interfaces. If you have either the static routes, or run you a dynamic routing such as OSPF or EIGRP Protocol.

    You may have a default route pointing to the firewall, a routing protocol dynamic running - so that all "internal" traffic will take place on the tunnel = encrypted vpn to a remote site, while all the 'internet' traffic routes to the firewall and leaves normally.

  • DMVPN divide tunnling question, not able to pass http traffic to end spoke.

    Hi all

    I would appreciate it please help me solve after publication.
    I've used installation DMVPN (EIGRP routing protocol) for 20 site no problem at all, and everything works perfectly.
    Now, I have received a request that I would need to divide the legitimate business and internet traffic to end talks, so all internet traffic via a local ADSL connection, but I tried to solve it but router speaks constantly forward all traffic to the tunnel.
    Moreover, I found on internet DMVPN a limitation that split tunneling isn't possible.
    Please can you suggest me how can I send internet traffic (HTTP) via a DSL connection local
    Thank you and best regards,

    DMVPN is not based on politics, split tunneling concepts not apply.

    DMVPN relies on the road to understand what traffic should be sent by tunnel.

    In your case, you also have to distinguish between the company and the Internet HTTP traffic, better correct routing in place.

Maybe you are looking for
