Several outside networks ASA - 1 outside the Interface

Example scenario:

A 20.0.0.0 (primary) site

Site B 30.0.0.0 (primary)

Greetings,

I don't see being a problem from a point of view routing with 2 routers on each site and advertisements via BGP. We will announce the two networks at each site. However, mainly single site will get 20.0.0.0 traffic and site B will get 30.0.0.0 traffic. No problem with the NAT and so on.

What I do not know how to deal with right now is if site B fails and the site began to receive the 30.0.0.0 traffic. There is just a single link between the router and firewall, site with the 20.x.x.x network. Any recommendations how A site can receive 30.0.0.0 transparent if site B goes bankrupt? (from a Point of view of ASA/NAT)

Thank you

Chris

It is reasonable to assume that your ASA has a road the 30.0.0.0 network she is inside the interface?

If so

static (inside, outside) 30.0.0.0 30.0.0.0 netmask 255.0.0.0

as long as the traffic to 30.0.0.0 is forwarded to the external interface of the firewall site has it can then accept this traffic and will forward it on internally.

If I understand you, let me know.

    Hello

    Are you able to ping the router IP of the interface of the device of the ASA? If so, try a trace of package on the device of the SAA for traffic to the IP address of the router.

  • Can not handle the ASA inside the interface of Site to Site VPN

    Hi all

    I was deploying new site to site between ASA 8.0 (HQ) and ASA 8.4 (branch). Everything works fine but I have a problem on the ASA-reach remote that I can't manage branch ASA with inside the interface IP address.

    My setup on remote ASA

    management-access inside

    ICMP allow any inside

    SSH 0.0.0.0 0.0.0.0 inside

    SNMP-server host inside 10.0.1.101 communitry test-snmp version 2 c

    My Test

    -ping of the AC for inside the interface of remote ASA

    • Client time-out see demand
    • When debug icmp on ASA remote then ASA show only ICMP request to HQ no response back from remote ASA

    I'm not sure whether it's a bug on ASA 8.4 or not because I can manage a remote other ASA what version 8.0 software HQ

    Thanks in advance

    Do not know what 8.4 version you use, but it is broken in the 8.4 (2), I stumbled upon the upgrade from same problem. SSH and ASDM will not connect through a VPN L2L interface inside. This worked well in 8.4 (1).

  • Not able to ping inside the interface from outside

    Hello

    I'm trying to stimulate a new network like the diagram of the topology below:

    Topology

    However, I have a problem:

    ASA:

    I can ping to:

    192.168.200.1 (Site_RTR IP, int fa0/1)

    192.168.200.2 (ASA vlan interface IP, outside interface)

    10.133.95.12 (DC_RTR, int fa0/1)

    10.133.200.1 (ASA vlan interface IP, inside the interface)

    10.133.200.23 (machine)

    The RTR website, I can do a ping to:

    10.133.95.12

    192.168.200.1

    192.168.200.2

    10.133.200.23 (machine)

    but not

    10.133.200.1 (ASA vlan interface IP, inside the interface)

    Question 1:

    It is possible to access / ping back to this address within the IP Interface from outside?

    Question 2:

    As all subnets 10.0.0.0/8 will go through the interface on the outside, however for the internet traffic, out thru interfacera outside 2.

    I haven't set up any nat, is correct to nat all out for outside2?

    NAT (inside outside2) source Dynamics one interface

    Configuration

    Thanks for the help.

    JJ

    Hi JJ,

    If you plan doing a ping within the IP address of the interface, while the traffic is coming from any interface other than inside, you won't able to ping inside the IP address of the interface.

    This is by design, and you cannot change it by any ACL or other settings.

    Thank you

  • Œuvres of VPn on the inside of the interface, but not outside

    I have a PIX-525 with UR license.  I tried to get my VPN to work since my iphone over the weekend, but nothing helped.  Then, I changed the interface inside to see if my iMac could connect and bingo!  It worked.  I then tried to log in via the inside of the interface with my iphone and it worked.

    I have connected a PIX-515e and, using the same settings, can connect to the external interface via my iPhone.

    Strange.

    Now, to answer the pressing questions, yes I changed the IP address of the server in my client IPSEC settings to reflect the external and internal interfaces I was testing each of them.  I was using a pré-partagées secret.  Yes, the secret has been entered correctly and they have all matched... Yes, the name of the tunnel has been entered correctly.  I used the database local user for authentication with username/password name (i.e. no certificate of authorization to make things simpler for debugging).  I changed the syslog to debugging and I see absolutely no error when you try to connect my iphone to the external interface (i.e. turn off wifi so I'm on my 3G data network).  The only thing I see is where my iphone hits the external interface and it's disassembly (or whatever his name is) but that's all.

    Why this work like a charm with my PIX-515e and not my PIX-525?  VPN accelerator card in the 525 can be at fault?  The 515e doesn't have the aecellerator card.  No idea why can't I several a VPN connection inside the interface but not outside?

    Hi Tim,.

    Well it's not so much the DNS rewrite that is the problem (if you delete just the keyword dns VPN will still fail) but using the external interface for NAT. So all traffic intended for your address of the external interface is passed to the "gcbrouter", including vpn traffic.

    I'm thinking about a way to solve this problem, but I really can't find anythign right now. Using a different interface will not work because you can have only a single default route.

    I wonder if this would work:

    remove the NAT interface:

    not static (DMZ, external) gcbrouter netmask 255.255.255.255 dns interface

    Replace with PAT interface, i.e. add such a line for each port that you want to be contactable on the DMZ server:

    static interface tcp 80 gcbrouter 80 netmask 255.255.255.255 (DMZ, outside) dns

    static (DMZ, outside) of the 25 gcbrouter 25 netmask 255.255.255.255 tcp interface dns

    etc.

    In all honesty, I have never seen rewriting dns used with PAT so not quite sure if it will work.

  • Highway do not authenticate outside the network

    Hello

    I followed the following procedures and documents: http://pandaeatsbamboo.blogspot.fr/2014/06/collaboration-edge-expressway...

    First question: we should set up a server of zone "course" or a "path to Unified Communications" in the area?

    I have configured a server of crossing area, but I have been warned because I have no Unified Communications Traversal area.

    My configuration:

    * X VLAN: CUCM 10.5 10.5 unit, 10.5 CUPS, ExpressWay C X8.5.1, highway E X8.5.1 (1 of 2 network adapter), DNS server, ad server

    * VLAN DMZ: highway E (the second network card)

    * Outside: External DNS

    Client Jabber works in the network, but not outdoors.
    I want to know why...

    My external DNS configuration:

    _collab - edge._tls.mydomain.fr. 86400 IN SRV 10 10 8443 expe.mydomain.fr.
    _sips._tcp.mydomain.fr. expe.mydomain.fr 86400 IN SRV 10 10 5061.

    expe.mydomain.fr. 86400 IN a 130.79.192.51

    I also put my internal DNS (same name-online expe.mydomain.fr).

    Internal and external domain name is the same.

    I strongly suggest that you look over the deployment of the MRA guide.

    The area on Highway-C and E should be 'Unified Communications traversal area' as stated in the guide.  You should not use the ordinary Client/Server path box.

  • WRT1900AC of external storage outside the Local network

    I'm trying to set up my WRT1900AC router to access a USB attached as an external storage device. I can access the drive when I'm on the LAN, but I had no success accessing outside my local network. I enabled the FTP option in the section of external storage. With the FTP option is enabled, it then points me to the IP address that my cable modem ISP attributed to the router (192.168.0.2). Obviously this won't work from the outside world because it is not the IPV6 address. I install my modem cable to the port before 21-the 192.168.0.2 address and tried to access from outside by using my address IPV6 (ftp://77.XX.XXX.XX:21) but it will not connect. I was hoping someone could point me in the right direction, as I obviously don't do something here.

    TVCS: event = "Call rejected" Service = "SIP" Src - ip = "IP address" Src-port = '5060' type-aliases-Src = Src-alias "SIP" = "sip:[email protected] / * /" Dst-alias-type = "SIP" Dst-alias = "sip:[email protected] / * /="Call-serial-number="aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeee" Tag "zzzzzz-Davis-0000-1234-xxxxxxxxx" detail = 'Not found' Protocol = "TCP" response code "404" = Level = '1' elements UTCTime = "2015-06-15 13:26:03, 214"

    If I check the call history, I see that my test call is not crossed:

    Hey Denis,

    It seems that you might have some problems.

    • VCS - C you have a search rule that targets CUCM, but it does not perhaps not for you for 2 reasons.
    1. It's the same priority as your rule of research area of course which may cause routing loops. Change the rule for targeting priority CUCM 100 to something between 50 and 100.
    2. It will only forward calls to CUCM which begin with a 3 and are followed by 3 numbers ending by mydomain.fr(.*). If you are URI calls that do not match this pattern, they will not be sent to CUCM. Make sure to set your match of regex to include your models DN so that your schemas URI incase they are figure not URI.

    Make these changes, and you may have more luck. Make sure also that your CUCM is configured to allow the composition of the URI. Ensure that the device that you are calling has a URI configured on the line.

    Once you make these changes to retest a call. If that fails, send the history research of the failure of the attempt. You can find it on the VCS under status > Search History.

  • 5 view customer disconnects immediately outside the local network

    I work with the 60 day trial of view 5.0 5.0 w/ESXi. Everything is configured and works well inside the LAN, but we have not been able to connect outside the local network. We have a single sign-on server that is associated with a single security server. All the rules of firewall, file server and configuration procedures correspond to installation and administration guides. Try to connect via PCoIP from a variety of devices.

    The client connects, check credentials, allows you to choose a desktop, opens the window of the office, but him freezes and shut up saying: 'the connection to the remote computer is complete.' This happens every time.

    Anny suggestions?

    Hello

    First of all, are you just a black screen that stays there for about 30 seconds then it closes with error? It is usually a problem with the connection to PCOIP. Could be firewall rules blocking a port, it could be the NATs. Security servers can be hard enough for the Setup program.

    First check and see if you can connect by using the view client and RDP Protocol. Also, make sure that through the firewall, the Security Server can access the VLAN Office on tcp/udp 4172. Search for NATing in the external firewall and that your security server for installation of the connection to the server has the external IP address that there are listed (not the internal IP of the server security).

    If you have a team network to talk to them and see if they can track packages. Look at the logs on the server and Security Office.

    You don't have to worry about this error. Security Server does not need to be on the field, in fact it should not really be on the field. It somewhat defeats the purpose of having a security server. The client has authenticated the username and the password and is spent on the desktop then ok. If the Office is unable to connect the user for a reason, then they will be left on the desktop windows request a user name and a pass.

    Hope this helps

  • Can I manage ESXi with the GUI Client from outside the private network?

    ESX Server 3i, 3.5.0 123629

    HP ProLiant ML370 G5

    1 P2V Windows 2003 SBS Server virtualized hosting

    Company has 5 static public IP addresses. One is used by SBS, another for the public wireless network. I would use a third party to be able to access the ESX and perform remote management.

    I am able to use SBS Remote Workplace hop on the server or any computer of client desktop and can run VI Client from there, but prefer to do it from my computer so I don't attach resources to the office. two vSwitches - vSwitch0 is the 'network' and vSwitch1 is the "Public network". I configured a VMkernel Port on vSwitch1 like the default (vSwitch0) "network management". vSwitch1 takes the address of the gateway on the private network and when I change it to the ISP on vSwitch1, it also changes on vSwitch0.

    Is this possible?

    Welcome to the VMware community forums.  The VMkernel can have as a gateway, so that's why on vSwitch0 changes when you change vSwitch1.   Technically, there is nothing to stop you adding another on vSwitch1 and vmkernel port giving a public IP address (which you can then connect to the VI client).   That said, it's not recommended to to do.  The management for ESXi port is best left on a private network and possibly protected by a firewall.   Put the vmkernel Internet port would be like putting IP to an IP SAN management or the management of a switch on the Internet.  Yes you can do it, but this isn't a good idea.  Instead, you might consider putting in a simple VPN server and then connect to ESXi through that.

    Hello Kenneth,

    Based on the appliance's routing table, I can see the following

    C 10.21.9.0 255.255.255.0 is directly connected, DeviceManagement

    C 10.21.3.0 255.255.255.0 is directly connected, servers

    C 192.168.210.0 255.255.255.0 is directly connected to the inside

    And you try to connect to the 3 of them.

    Politics of Split tunnel is very good, the VPN configuration is fine

  • Allow specific access through the Interfaces ASA 5510

    Hi all

    In my quest to learn Cisco IOS and devices, I need help in smoothing traffic, or access lists, allowing traffic between internal interfaces on the SAA specifically.

    I have an ASA 5510:

    WAN/LAN/DMZ ports labled E0/0 (LAN), E0/1 (WAN), E0/2 (DMZ).

    Connected to the port E0/0 is a 2811 router

    Connected to the port E0/1 is the (external) Internet

    Connected to the port E0/2 is a 2821

    (I'll add a 3745 for VOIP) port E0/3, but it has not yet happened.

    I want to allow traffic between the 2821 and the 2811 routers so that devices on the networks behind them can talk to each other.

    I've specified specific subnets between the ASA and the routers because I want to learn how to shape traffic behind routers, as well as on the ASA. So behind the routers I have different VLANS, but I'm not restrict access between them, still, at least I don't think I am. But as it is, behind the 2821 devices cannot access the DNS / DOMAIN SERVER that is located behind the 2811. Right now I have the routers DHCP power, who works there. Currently devices behind the router 2821-3560 switch cannot access the domain server, primary dns server.

    How can I set the ASA to allow traffic to flow between the two routers and their VLANS?

    Here's the configs of each device and I have also included my switch configs, incase something should be set on them. I only removed the passwords and the parts of the external IP address. I appreciate the help in which States to create and on which devices.

    I think it is best that I put the links to the files of text here.

    Thank you!

    You must remove the following statements on the two routers:
    -# ip nat inside source... overload
    -for each # ip nat inside/outside interface, if they have configured.

    Remove ads rip of the networks that are not directly connected:
    -2821: 172.16.0.0, 192.168.1.0, 199.195.xxx.0
    -2811: 199.195.xxx.0
    -ASA: 128.0.0.0

    No way should be added to the routers, since he is the one by default, put in scene to ASA.

    Check the tables of routing on routers and the ASA.

    On ASA:

    -Remove:
    object-group network # PAT - SOURCE
    # nat (indoor, outdoor) automatic interface after PAT-SOURCE dynamic source

    -create objects of the networks behind the LAN router and enable dynamic NAT:
    network object #.
    subnet
    NAT (inside, outside) dynamic interface

    -review remains NAT rules.

    -to set/adjust the lists access penetration on the interfaces. Do not forget to allow the rip on the LAN and DMZ interfaces.

    -Disable rip on the outside interface.

  • Network for access to the external interface inside

    Hey,.

    I have an ASA5520 7.2 (1) I have a few probs with - which is something I struggle with that.

    I'm trying to hit a website of a host on the inside network that is actually hosted internally, but decides the static NAT would focus on the external interface of the firewall.

    Now I can see the TCP built, translation occurring at a port on the external interface, this port high dialogue to one of the static electricity would be addresses on the external interface, then that's all. There are no more entries in my journal in regards to the connection and I get not syn on the internal web server is so the connection is not back in.

    IP address inside 192.168.87.1 255.255.255.0

    Static NAT to Web servers: -.

    public static 222.x.x.10 (Interior, exterior) 192.168.87.5

    access lists access... :-

    list of allowed inbound tcp extended access any host 192.168.87.5 eq http

    Access-group interface incoming outside in

    Everything works fine when creating a global internet address - just not when address from inside and dynamic PAT is performed to the original address.

    Here's a capture session by using the following access to capture list inside and outside interfaces simultaneously

    permit for line of web access-list 1 scope ip host 222.222.222.10 all

    web access-list extended 2 line ip allow any host 222.222.222.10

    on the INSIDE interface (nothing is connected to the outside) (ip addresses have been replaced by nonsense) - but address 222 is would take into account the interface static and the other is on the internal network.

    Someone of any witch hunt, which is stop this function work?

    All networks are directly attached and there is no route summary ancestral anywhere.

    I hope you guys can help!

    To my knowledge the ASA supports only hairpining on a VPN tunnel. The security apparatus does not allow traffic that is sent to an interface to go back in the direction of what she received.

  • Can the interface of management firepower &amp; ASA-Inside interface be on separate subnet?

    HI -.

    Need a few more details, please.

    I have a requirment needed to put the power of fire management interface and the interface of the ASA-Inside on different subnets, supports?

    From what I've read so far, most of the document suggests to put two interfaces on the same subnet, is there a reason to do so?

    I may be wrong but I think that fire use management interface to communicate with FireSight for control and comamnd traffic, data traffic real plan always flows from ASA-outside to inside and vice versa, both there are connectivity ip between FireSight and firepower, it should be ok, right? or am I totally wrong, that they must be on the same subnet?

    ASA5515-x with the firepower 5.3.1

    Thanks in advance for your help.

    Separate subnets are fine.

    As you have seen correctly - the module of firepower has need to contact FireSIGHT Management Center (IP-wise).

    This path is completely independent of the plan through the ASA data path. The ASA redirects the traffic via the service strategy for the module of firepower entirely internally to the unit.
