• VPN inside and on a PIX DMZ

  Hello

  I've got 2 PIx 515E with UR 1 and 4 Ethernet 1 506th both in 6.3.4.

  I tried to make VPN between Toulon and Montreal.

  In Toulon, I can communication of inside the demilitarized zone and inside the Montreal network

  Montreal, I can communicate in Toulon inside the network.

  But disclosure of the dmz of Toulon for of Montreal and Montreal to Toulon DMZ network.

  I got a Syslog message saying that it is not possible...

  How could I solve this problem?

  Thank you very much

• Client VPN on PIX needs to access DMZ

  VPN clients 3.5 ending PIX 6.X cannot access hosts on a PIX DMZ interface. Journal reports of error that there is no 'translation group available outside' for the subnet of the VPN Client (from the vpngroup pool).

  I should add the VPN client subnet to a nat (outside) device?

  Can I add it to the nat inside?

  Can I just add static to the DMZ hosts within the subnet interface because VPN clients can access the inside hosts?

  (I have the subnets in the nat 0 sheep ACL)

  Thanks and greetings

  JT

  You'll need to add is nat 0. You say in your () you have an acl sheep, for the perimeter network or the inside interface? You use the same access list to the sheep inside and dmz? You should separate if you use separate access list. Is your pool of client on a different subnet than your home network and dmz? It must be something like this:

  Customer IP local pool 192.168.1.1 - 192.168.1.254

  IP, add inside 10.10.10.1 255.255.255.0

  Add 10.10.20.1 dmz IP 255.255.255.0

  access-list sheep by 10.10.10.0 ip 255.255.255.0 192.168.1.0 255.255.255.0

  nonatdmz list of access by IP 10.10.20.0 255.255.255.0 192.168.1.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  NAT (dmz) 0-list of access nonatdmz

  If this is correct then clear x, wr mem, reload. I hope this helps.

  PS

  If he did not, only can recommend the upgrade your client and pix because that is exactly how it should look, and if its does not work you are facing an additional feature you want.

• Customer Pix unit inside and dmz networks

• DMZ and PIX failover

  Hello

  I'm pretty happy with the tipping of inside and outside interfaces - i.e. the backup PIX inherits the IP address and MAC address of the main unit. However, what about the DMZ interface? Which also inherits the IP address and MAC of the primary unit?

  In a design of failover DMZ with only a couple of servers on the DMZ, you connect two PIX DMZ interfaces into a common switch (same VLAN of course!) and then plug servers?

  Pretty basic questions, I don't know, but I cannot find an answer to this on cco.

  Best regards, Steve

  Hi Steve,.

  Yes... DMZ interfaces inherited also the IP and MAC address of the primary PIX.

  In this scenario, even if you have a server you need to plug the 2 PIX on a switch and then the server on the same VLAN... This will ensure the physical accessibility of the server at the same time PIX. In case you have only a single connection, you must change the cable manually, when a PIX fails, which is a big headache...

  I hope this helps...

• PIX 515e, multiple VIRTUAL networks on a physical interface to DMZ

  We try to set up multiple VIRTUAL networks on a physical interface to the DMZ on a PIX 515e.

  The goal is to have logical subnets linked to our single, physical interface DMZ.

  Here's what I've tried so far without success:

  -created the vlan 30

  -added switchports fa0/1 to 30 of vlan

  -attached host 192.168.100.1 in fa0/1

  -added switchport fa0/24 to the vlan 1 and vlan 30 with multimode

  -interface PIX DMZ connected to fa0/24 switchport

  -attached host to switchport fa0/10 172.16.1.55 (vlan 1)

  PIX:

  -192.168.100.1 cannot ping the PIX to the 192.168.100.254 or anything else besides.

  Any help would be greatly appreciated. Also, I realize that I could buy a four port NIC and use the physical interfaces, but I can't get the approved purchase.

  Creation of VLANS on Ethernet1

  We want to create a new interface VLAN - VLAN30 and name DMZ2. Also affect the security level 50 in it.

  Step 1: Create a physical Interface:

  PIX (config) # interface ethernet1 vlan2 physical

  Step 2: Name the Interface and set the security level:

  PIX (config) # nameif ethernet1 inside the security100

  Step 3: Assign the IP address of the interface:

  PIX (config) # ip inside 192.168.1.1 address 255.255.255.0

  Step 4: Create the logical Interface:

  PIX (config) # interface ethernet1 vlan30 logical

  Step 5: Name of the Interface and set the security level:

  PIX (config) # nameif vlan30 DMZ2 security50

  Step 6: Assign IP address to the interface:

  IP pix (config) # DMZ2 192.168.100.254 255.255.255.0

  Step 7. Switch, set the port where from the inside, to the Isls or dot1q physical interface. Place the sheath in the native vlan2 as in step 1.

• VPN concentrator + PIX on LAN-&gt; customers can not reach local servers

  Hello

  I have a problem wrt. remote access clients coming via a VPN3000 concentrator and trying to access local servers.

  For the topology:

  The internal network is 10.0.1.0/24. It connects with the outside world, as well as via a PIX DMZ; the PIX has 10.0.1.1 in the internal network.

  On the same LAN (internal), I have the VPN concentrator for the inside address 10.0.1.5. It assigns addresses in the 10.0.100.0/24 range to the

  VPN client-PCs.

  I can sucessfully connect using the VPN client SW to the hub, i.e. remote access clients out addresses

  the 10.0.100.0/24 range.

  The problem: access from VPN clients to internal network is * not * possible; for example, a customer with 10.0.100.1 cannot connect to

  internal to the 10.0.1.28 server.

  To my knowledge, this is a routing problem because the server (10.0.1.28) has no idea on how to reach customers in

  10.0.100.0/24. The only thing that the server is a default static route pointing to the PIX, i.e. 10.0.1.1.

  So I set up a static route on the PIX for 10.0.100.0 pointing to the hub-VPN, that is

  Mylan route 10.0.100.0 255.255.255.0 10.0.1.5 1

  This does not solve my problem though.

  In the PIX logs, I see the entries as follows:

  % 3 PIX-106011: deny entering (no xlate) tcp src trainee: 10.0.1.28 (atlas) / 445 intern dst: 10.0.100.1 (pending) 1064

  The PIX seems to abandon return packages, i.e. traffic from the server back to the client

  To my knowledge, the problem seems to be:

  Short traffic VPN - client-> Concentrator VPN-> Server-> PIX - where it gets moved.

  My reasoning: the PIX only sees the package back, i.e. the package back from the server to the client - and therefore decreasing the

  package because he has not seen the package from the client to the server.

  So here are my questions:

  (o) how do I configure the PIX that I be connectivity between my remote VPN clients (10.0.100.0/24) and

  computers servers on the local network (10.0.1.0/24)?

  (o) someone else you have something like this going?

  PS: Please note that the first obvious idea, installation of static routes on all machines on the local network is not an option here.

  Thank you very much in advance for your help,.

  -ewald

  Hello, PIX the because can not route traffic on the same interface (prior to version 7.0 anyway), I suggest you two places your hub to the outside with the inside of the legs on a zone demilitarized or (if you can not do a makeover of the network) you remove your pool with 10.0.100.0 - addresses and create a pool with 10.0.1.0 - addresses which is a part of the address space. No, NOT all. A little book that it is not used inside.

• ASA - DMZ - LOTUS NOTES ACCESS SEGMENT

  Hello

  I hosted lotus notes server and citrix servers in the DMZ segment of the asa. Access remote vpn has been configured. Users use vpn to access the servers. Users are not facing any problem when they try to access citrix and other servers after the connection to the vpn.

  But when they try to access the server lotus notes using lotus notes client after authentication are not able to view their mailbox. When they try to telnet to the port 1352 it is successful. When they ping to the server works very well. But not able to view emails. That is to say the server does not.

  I updated the entry of the host also in the files of the host of the client computer. But users of windows 98 operating system is able to display emails. But not in windows xp.

  Let me know what we can do in asa.

  When we replaced asa with pix, it works fine. But the servers are not hosted in in pix dmz segment.

  Krishna,

  Please check the domain/DNS suffix. We had similar problems and it was resolved after you have added the DNS suffix on the General attributes for the VPN clients group.

• DMZ connected network is not available

  My configuration:

  PIX - servers with gateway as pix - DMZ dmz - remote router - remote LAN

  When I try to reach remote LAN to dmz servers that I'm not able to reach.

  My servers have pix as gateway.

  PIX has road for Remote LAN. (PIX I n t have no problem to reach remote LAN)

  When I add remote LAN-specific routes pointing to local router then I n t have problem to reach the Remote LAN.

  My problem is the why of the pix as the gateway server not able to reach remote LAN.

  the problem is related to the v6.x pix golden rule.

  the golden rule does not fundamentally pix redirect the packets in and out the same interface. for example, server dmz try to send a packet to the remote lan. for now, dmz server has a default gateway for the interface of a pix dmz, dmz server passes the packet to the interface of dmz pix to begin with. PIX receives the packet comes from the dmz server and the remote lan. now, pix determines the next hop for this particular package is the router in the dmz, which is once again through the DMZ interface. as mentioned, the golden rule does not allow this operation because the packet is received on the interface of a pix dmz.

  the workaround, as mentioned earlier, martin is to change the default gateway on the dmz server. the default gateway should be the router in the dmz, then configure static routes on router.

  now, there are two choices with regard to the configuration of the ports on the router.

  a: Configure the pix as the gateway router dmz dmz interface by default and configure the static route to the Remote LAN. or

  two: Configure the remote router as the default gateway of the router dmz and configure a static route for pix inside the net.

  personally, I prefer the first options as server dmz may need access to the internet via the pix as well.

  leaving again watching the flow of traffic to dmz, DMZ router as the default gateway server; router DMZ with interface dmz pix for the default gateway and the static routes for remote lan.

  package from Server dmz for the lan remote will be forwarded to the dmz router. DMZ router will then forward the packet to the remote router based on the static routes; Alternatively, package from Server dmz to the internet or the pix inside the subnet will be forwarded to the dmz router. the dmz router will then package the pix dmz interface based on the default gateway settings.

• VPN Tunnel to the TOP but no traffic passing (PIX515)

  I'll put up a remote engineers access to off-site to access my network (using the cisco vpn client). I use PIX 515E software version 7.0 (3) 20 as a vpn server. I can establish a tunnel, but I can't access network resources. I can ping the external interface of the PIX. This is my setup: internet-router-pix-dmz(server farm). Please find attached my setup. Thanks in advance.

  After a glance at your policy, it seems that the Pool of IP, that is assigned to the clients behind the outside interface, runs behind the DMZ. I don't think it will work.

  In addition, defined distribution policy seems to be backward. Im sure that you intend to send traffic FROM the IP pool to 196.26.12.64/26. Your acl split is the opposite.

  In addition, your routing table does not contain a route for the 196 network, so the firewall will use the default route to the outside. If this is intentional, the clients and dst are on the outside, which is considered to be crossed. This is allowed on the SAA only with the same security setting configured.

• Setting up a public external interface and NAT

  Hi all

  I recently acquired a 27 subnet that gives me IP addresses public 30 (for example 1.1.1.0 - 1.1.1.32). What I wanted to do are to the subnet that subnet more for the following purposes:

  1.29 subnet for use on the PIX outside interface as well as other devices such as routers, hsrp.

  2.29 subnet to use NAT on a PIX DMZ interface.

  3.28 subnet is reserved for future use

  I have no problem putting on IP addresses, but just wanted to know if it is better for me to combine 1 & 2 together to make a 28 subnet outside and set the global pool so that it contains the 2nd 29 subnet (for example 1.1.1.9 - 1.1.1.16) to eb the address using a NAT? Another question is what do I I opted to use the 28 subnet for networkm outside I would still be able to set a different 28 global pool address and do NAT?

  Thanks in advance for your answer.

  There is really no difference in this case, if you use a single 28 or 29 two subnets. In most cases, your ISP will announce a 27 down to you. The PIX will respond to all ARP requests to addresses he ' owns ' (unless you are running 6.3 (1) - we had a change to be regularized in this version) regardless of source of demand.

  This help at all?

• PIX with H &amp; S VPN DMZ hosting web server to the hub

  Ok

  Heres a problem which I think would be quite common for these even remotely conscious of security. Unfortunately, my knowledge of the PIX (as well as other Cisco devices) is still in phase of 'growth '.

  So, here's the problem. I have a WAN put in place with PIXen and SonicWalls, we are set up in a design essentially Hub and Spoke (fine ok so it is partially meshed). We recently decided to pull the trigger on getting a 'real' web site and everything went relatively well that getting up and rolling. (even with my notice of 3 days/deadline), but here's the problem: I set up the web server on the DMZ to the hub pix, and I figured out (the easy part) how to set things so in the Home Office, people can connect to the web server by using the internal address, but I don't know what to do for people in remote offices with VPN home connections. I tried to define static routes, I tried to add the DMZ to the VPN trigger, I tried to do both of the last things together, and I checked that I have rules allowing traffic to the VPN outside the DMZ on the inside. So, what else can I I get?

  I have no problem by configuring a PIX for all basic ups and VPN even at this stage, I can do most of it through the CLI (even if I still want to do more through the PDM). My biggest stumbling block on the PIX has so far was when I actually involve this pesky DMZ...

  I actually two PIX in my office, two for my network domestic (one for my place in the States and one for my place in the Japan), so if you can help me, I'll be the two problems and do not forget to give a rating of excellent reviews!

  so I guess that leaves me to the place where I scream...

  Help!

  and I humbly await your comments.

  the current pix configuration should look at sth like this,

  IP access-list 101 permit

  IP access-list 110 permit

  Global 1 interface (outside)

  (Inside) NAT 0-list of access 101

  NAT (inside) 1 0.0.0.0 0.0.0.0 0 0

  Permitted connection ipsec sysopt

  Crypto ipsec transform-set esp-3des esp-md5-hmac superset

  myvpn 10 ipsec-isakmp crypto map

  correspondence address card crypto myvpn 10 110

  card crypto myvpn 10 set by peer

  superset of myvpn 10 transform-set card crypto

  interface myvpn card crypto outside

  ISAKMP allows outside

  ISAKMP key

   address netmask 255.255.255.255
  
  isakmp identity address
  isakmp nat-traversal 20
  isakmp policy 10 authentication pre-share
  isakmp policy 10 encryption 3des
  isakmp policy 10 hash md5
  isakmp policy 10 group 2
  isakmp policy 10 lifetime 86400
  now, to add dmz on top of the existing vpn, add the following to the pix (and apply the same concept on the remote end device)
  access-list 102 permit ip
  access-list 110 permit ip
  nat (dmz) 0 access-list 102
  

• PIX vpn public dmz

  Hello

  I d wishes to establish a vpn to a pix firewall 515 and pos version

  7.0 (5) with a public dmz and nat translation.

  inside: 10.5.10.0/24

  outdoors: 1.1.1.1/27 (Beach)

  DMZ: 2.2.2.2/27 (Beach)

  distance inside the network:192.168.20.0/24

  My area of encryption should be: 2.2.2.3/32--192.168.20.0/24

  announcement I have a nat rule, which is:

  NAT (inside the dmz) 2.2.2.3 10.5.10.28 netmask 255.255.255.255

  So basically I want to translate the connections coming from 2.2.2.3 to

  10.5.10.28

  the vpn is configured correctly and set up both sides, but the nat rule

  with the vpn doesn't work.

  Built of incoming TCP connections to outside:192.168.20.82/34237 4619

  (192.168.20.82/34237) at dmz:2.2.2.3/22 (2.2.2.3/22)

  but I can t see any traffic on the 10.5.10.28 Server, I see instead:

  Built of incoming TCP connections to outside:192.168.20.82/34237 4619

  ((192.168.20.82/34237) at dmz:10.5.10.28/22(10.5.10.28/22)

  any help would be great!

  Kind regards

  Could you specify just the line

  NAT (inside the dmz) 2.2.2.3 10.5.10.28 netmask 255.255.255.255

  should we read

  2.2.2.3 static (inside the dmz) 10.5.10.28 netmask 255.255.255.255

  Also are you terminating the VPN on the external interface of your firewall is to say what is the IP address of the peer to your end.

  You might not try

  static (inside, outside) 2.2.2.2 10.5.10.28 netmask 255.255.255.255

  * Edit - I meant

  static (inside, outside) 2.2.2.3 10.5.10.28 netmask 255.255.255.255 *.

  You need not actually traffic to DMZ, you?

  If not do you have IP addresses available in the public system on your external interface?

• Is it possible to build a vpn tunnel to the DMZ on a pix 515 interface?

  I would like to know if it is possible to have a vpn tunnel ending on a DMZ interface rather then inside interface of a pix 3-way. All the examples of configuration, I found route traffic from the VPN client somewhere on the internet on the inside interface of the pix. I tried a sheep-access list of the demilitarized zone to the vpn client, but it does not work. According to me, because the vpn traffic goes to the safety higher by definition interface. Am I wrong?

  Hello

  You can do it in use (nat 0 dmz x.x.x.x y.y.y.y)
