VPN and VLAN

• Firewall VPN, VMs and VLAN

  It is just a simple example to help me understand.

  Let's salsa in my data center, I have a simple setup with 1 firewall (LAN port) connected to the server physical 1' data network port. The server has two network, 1 data and 1 management ports.

  3 branch offices are connected to the WAN port on the firewall via VPN, and each office is on a separate subnet. The firewall is capable of creating VLANs of course. For example, I can direct traffic to office 1 to go to the VLAN 1 which is the 1st Port of the firewall.

  The requirement is that each office wants their own virtual machines. Virtual machines for an office are not allowed to talk to other virtual machines for other offices.

  How can I set up? How I would order traffic to office 1 to go to the VLAN1 where VMs for Office 1 would also live and then do the same for Office 2 & 3? I need 3 network ports (one for each office) on the physical server to accomplish this or I could use "vSwitch' function?

  No additional need to NICs. We establish Setup with existing maps.

  1. create 3 VLANs (for example: 11,12 and 13) for each office.

  2. set the switch port physical/firewall which is connected to taking data network of servers in TRUNK mode. Its to allow the traffic of all the VLANS.

  3. create 3 exchanges in vswitch (for example: 1, 2 and 3 office)

  4 VLANs for each card exchanges.

  VLAN 11-> office1

  VLAN 12-> office2

  VLAN 13-> guidelines3

  5. connect the virtual machines to their respective trade.

• SSL VPN and routing problem

  Hi all

  I have a strange architecture including VPN and I have a few problems that I am not able to solve:

  -J' use the ssl vpn gateway to allocate internal IP addresses of the local network described in the schema (8.8.2.0 or 8.8.3.0 according to the tunnel-group network.

  -The purpose is for vpn clients directly access the internal network.

  This works very well if there are strictly internal communications within the network. But recently, we have installed an application that needs to access both networks. No problem, I thought, but I was wrong, there seems to be a problem of routing inherent in the architecture in place.

  Let me explain the problem:

  -When I access the VPN, for example I will gave the 8.8.3.5 ip address.

  -Im running the application that needs to open a page on the web server, located at 8.8.2.120

  -l'asa receive my tcp syn datagram and forward it directly to the directly connected interface fa0/1 (based on the routing table)

  -the web server returns the response, but he sends on its default gateway which is the cisco 6509.

  -6509 it sends its vlan svi 2000

  - and finally the ASA it receives on its interface fa0/2 but seems he falls as she opened a tcp on fa0/1 connection and receives the response on fa0/2.

  I want it's traffic by tunnel to bypass the connected roads and transmit it to a default gateway of tunnel. This would ensure that the path for the request and the response would be the same.

  I would like to know if there are orders of debugging for routing decisions validate my theory?

  Do you know of any response to solve this problem?

  Thanks a lot for your help.

  When you configure the TCP State derivation always think ' which way is the SYN package coming?

  Routing failed messages always have source and destination, are of course copied the entire message?

  BTW, instead of letting clients SSL addresses attributed to vlan2000? Why not give them a separate subnet and the road back via correct interface?

  I would also check your config and the routing :-) table

• RVL200 - SSL VPN and firewall rules

  Forgive my ignorance, but I have been immersed in the configuration of this device RVL200 to allow Remoting SSL VPN to a customer site, sight unseen.  I have the basics of the VPN set up in config, but now move the firewall rules.  We want to block all internal devices to access the Internet, but I don't want to cripple the remote clients that will be borrowed by blocking their return via the SSL VPN traffic.  This leads to my questions:

  (1) a rule of DENIAL of coverage for all traffic OUTBOUND will prevent the primary function of the VPN (to allow the administration away from machines on the local network)?

  (2) if the answer to #1 is 'Yes', what ports/services do I need to open the side LAN?

  (3) building # 2, configuring authorized outbound rules apply only for VPN clients, rather than all the hosts on LAN?

  (4) as the default INCOMING traffic rule is to REFUSE EVERYTHING, do I have to create a rule to allow the VPN tunnel, or guess that in the configuration of the router?

  Here are some other details:

  • The LAN behind the RVL200 is also isolated LAN in a manufacturing environment
  • All hosts on this network have a static IP address on a single subnet.
  • The RVL200 has been configured with a static, public IP on the WAN/INTERNET side.
  • DHCP has been disabled on the RVL200
  • Authentication to the device will use a local database.
  • There is no such thing as no DNS server on the local network
  • The device upstream of the RVL200 is a modem using PPPoE DSL, and the device has been configured for this setting.
  • Several database of local users accounts were created to facilitate the SSL VPN access.

  I worked with other aspects of it for a long time, but limited experience with VPN and the associated firewall rules and zero with this family of aircraft.  Any help will be greatly appreciated.

  aponikikay, there is no port forwarding necessary to the function of the RVL200 SSL - VPN.

  Topic 1. That is not proven. It shouldn't do. The router should automatically make sure that the SSL - VPN router service is functional and accessible.

  Re 2. No transfer necessary. In addition, never before TCP/UDP port 47 or 50 for VPN functions. The TCP 1723 port is used for PPTP. UDP 500 is used for ISAKMP. You usually also to transmit TCP/UDP 4500 port for IPSec encapsulation.

  Let's not port 47. ERM is an IP protocol that is used for virtual private networks. It is a TCP or UDP protocol. GRE has 47 IP protocol number. It has nothing to do with TCP or UDP port 47. TCP and UDP are completely different protocols of free WILL.

  It goes the same for 50: ESP is the payload for IPSec tunnels. ESP is the Protocol IP 50. It has nothing to do with TCP or UDP port 50.

  'Transfer' of the GRE is configured with PPTP passthrough option.

  'Transfer' of the ESP is configured with IPSec passthrough option.

• Connect to VPN and then log on to the domain by using different credentials.

  I have a laptop user who will take care of various remote sites.

  In XP, you had to first use DUN/VPN and then you can log in the field with different credentials that the VPN end point.

  With Vista if I use the method user to switch on the logon screen and the log in the VPN it also attempts to use these credentials for the domain.  The VPN device has its own separate authentication of the AD.  How to restore the loss of functionality that Vista has?

  I have to first connect to the VPN appliance and authenticate to that I do the network connection.  Then, I need vista to propose real logon to the computer or to the domain.

  I appreciate the help.

• PowerConnect 5548 and VLAN

  Good afternoon!

  I'm looking to implement a 5548 in our existing infrastructure. I want to preface this by saying that I am very new to networking.

  I'm looking to have at least two VLANS separated.

  -The first vlan for public sites face. These will have static public IP addresses.

  -The second VLAN is iSCSI traffic. I would like that it won't face public.

  Is it possible to Setup or should I be looking for a different solution.

  If possible, how should I go about setting up?

  Thank you!

  The port that connects to your router should be placed in Trunk mode with the VLAN you want in the trunk port. All ports are in VLAN1 access mode by default, this means that the port that plugs into your routing device is in access mode for VLAN 1 and VLAN 1 has internet access. For traffic VLAN 2 to access routing equipment that you will need to change cela port in Trunk mode and adds 2 VLAN as a VLAN Tag.

• Subinterfaces and VLAN

  Hi all

  I was hired on with a State... Now its been awhile, but I do not remember how subinterfaces and VLAN all link together!

  Now correct me where I'm wrong (please), but them VLAN is created on the correct first switches?  When you create a VLAN on a switch you don't need ip or gateway address by default because them VLANS are the switch.  If you want intervlan routing you need a router.  Then, you configure a port trunking between the switch and router (ISL, 802. 1 q).  Now in the router, you can create a VLAN, and here you inter the ip subnet or the default gateway addresses correct?  This is where I get confused as to what reasons do you need subinterfaces?  How they roped VLAN and what would be the logical flow of data?

  Anyhelp would be appreciated!

  Yes you are right. If you are using the layer 2 switch and want to make the intervlan Routing then you need Layer 3 router device. But you must configure the interfaces sub with the default gateway to route traffic. Because there is a single trunk between swich and router so we need sup interfaces for multiple VLANs.

  Interface FastEthernet0/0.1

  Encapsulation dot1q 10 (10 represent 10 ID VLAN)

  10.1.1.1 IP address 255.255.255.0

  If you use a layer 3 switch, then you point all sub interfaces need so then you can create the interface vlan with the default gateway. You must enable ip Routing.

  Interface vlan 10

  10.1.1.1 IP address 255.255.255.0

  Hope this will help.

  Please rate if this can help.

• site2site distance-VPN and access-PIX - no way?

  I have,

  I have a problem wrt site2site & VPN remote access on a PIX:

  My setup is as follows: PIX (6.3) puts an end to two a site2-site VPN and also should the remote access service clients using the client VPN Cisco (4.0.x).

  The problem is with remote access VPN clients, obtain an IP address on their VPN interface, but customers cannot reach anything. (Please note that the site2site VPN runs without problem)

  To be precise (see config-excerpts below):

  The customer, who has 212.138.109.20 as its IP address gets an IP 10.0.100.1 on his card-VPN which comes from the "vpnpool of the pool.

  configured on the PIX. This customer relationships to reach servers on interface 'inside' of the PIX as 10.0.1.28.

  However, the client cannot achieve * nothing *-a server on the inside or anything like that (e.g. Internet) outside!

  Using Ethereal traces, I discovered that the packets arrive inside interface coming 10.0.100.1 (IP address of the)

  VPN - client). I also see the response from the server (10.0.1.28) to 10.0.100.1. However for some reason any package does not thanks to

  the PIX to the customer. PIX-newspapers also show packets to and from the VPN client to the inside interface - and * no. * drops. So to my knowledge the packets from server to the VPN client really should be done through the PIX.

  I have attached the following as separate files:

  (o) the parts of the PIX config

  (o) packets showing PIX-log between the VPN client and the server (s) on the interface inside

  (o) ethereal-trace done inside the watch interface also packets between VPN client and server (s)

  I have really scratched my head for a while on this one, tested a lot of things, but I really don't know what could be a problem with my

  config.

  After all, it really should be possible to run site2site - and on the same PIX VPN remote access, shouldn't it?

  Thank you very much in advance for your help,.

  I think that your problem is in your ACL and your crypto card:

  access-list 101 permit ip 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.0.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.3.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.1.0 255.255.255.0 10.0.100.0 255.255.255.0

  correspondence address 1 card crypto loc2rem 101

  This means that this map correspond to these addresses. But your dynamic map is one that must match 10.0.100.0, 10.0.1.0 traffic because your pool local ip is 10.0.100.x. I think what is happening is that the return traffic from the lan to vpn clients trying to get out of the static tunnel, which probably does not exist (for the netblocks - you probably have a security association for each pair of netblocks, but not for vpn clients) and so do not.

  I would recommend adding these lines:

  access-list 105 allow ip 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 105 allow ip 10.0.0.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 105 permit 10.0.3.0 ip 255.255.255.0 10.0.2.0 255.255.255.0

  no correspondence address 1 card crypto loc2rem 101

  correspondence address 1 card crypto loc2rem 105

  Then reapply:

  loc2rem interface card crypto outside

• Question of VPNS and router

  Hello

  I currently have a RV042G in my company.  It works fine, but I was looking for a solution that would allow me to use VPN so that I can tunnel inside and then again connect to the internet via the tunnel.  I want to have a way secure to connect to internet from my laptop while I am travelling and prefer to build my own VPN and do it myself.

  If I understand correctly, the RV042G does not allow this and it only access to the local network via the tunnel. What would be the next router allowing him to fill this purpose?

  Thank you!

  Hi rodman

  These devices work fine, you can also use third-party software not only software from Cisco to use the VPN features. On subscriptions, IAPH supports more special features such link Protect and IP addresses and you can have and buy a subscription in order to add these features to your device, however, if Don t you want what they you don t have to buy.

  Cisco provide one of the best support, it has plenty of support, it is possible via chat, email or telephone, it also provide assistance free of charge for the users of this forum if you don t buy a warranty

  I hope you find this answer useful,

• AnyConnect VPN and LAN access

  When remote users to connect to the Cisco ASA VPN and authenticate with Cisco AnyConnect client, they then full access to the environment internal of LAN of business as if they were sitting at their desks in the Office of the Corporation.

  Right?

  After that the remote client authenticates to the AnyConnect VPN, it is sensible to then run remote users of traffic through the corporate firewall (outside to inside) before allowing LAN access full corporate?

  Remote_User - vpn - ANYCONNECT-(outside) (inside) firewall - CORP_LAN

  Thank you

  Frank

  Hello

  Yes, by default, all traffic will be sent through the tunnel.

  If there are users VPN shouldn't be able to reach the resources, you need to establish rules for access to it. The best way to do this is by using VPN filter.

• Create 2 VLAN (VLAN 1 and VLAN 2)

  Hi all

  I need help and advice with my new Cisco SF300-48. I want to create 2 vlan (vlan 1 and vlan 2). The switch is set at layer 2.

  example:

  VLAN 1 (port 1, 2, 3), vlan 2 (port 4, 5, 6)

  VLAN 1 can communicate with each other (port 1, 2, 3) and vlan 2 can communicate with each other (port 4, 5, 6)

  But vlan 1 cannot communicate with vlan 2.

  Any help would be appreciated

  Thank you

  Johan

  Well, as far as I understand the message communication between the VLAN is not necessary. The thing is, that all ports LAN VIRTUAL (for example VLAN 1 with ports 1, 2, and 3) cannot communicate with each other. Did you check the configuration of the port / VLAN (VLAN configured to each port configuration right / right about the tag-no identified)?

• Management and Vlan native in different subnet?

  Can I have a management ip and vlan native in a different on AIR-1242 switch subnet and 2960?

  Native on switch = 1.

  BVI ip to the vlan 100 = 10.10.1.25X 24

  Hello

  As far as I know, the management and the native will be the same... I guess... You have Vlan native as 1 on the switch and Int Vlan 100 on routing switch? Am I wrong? Let me know what are your needs... which will help me to help out you!

  for your question...

  Normally, we specify him vlan native on the switch and the AP so that communication happens... communication won't happen if there is a match of...

• Mac, VM XP Pro, Cisco VPN and printing.

  I have an end-user running a Mac with a virtual XP Pro Machine that connects to our VPN corperate machine. This part works fine. Problems happen when he tries to print to a network printer. The job is just until it disconnects from the VPN and then it prints very well. No one knows what to do to fix this? I have little or no knowledge of MAC.

  Kind regards

  This could be the reason why printing does not work. To print traffic really vpn tunnel as split tunnel is not configured.

• AnyConnect vpn and a tunnel vpn Firewall even outside of the interface.

  I have a (no connection) remote access vpn and ipsec tunnel connection to return to our supplier is on the same firewall outside interface.

  The problem is when users remote vpn in they are not able to ping or join the provider above the tunnel network.

  now, I understand that this is a Bobby pin hair or u turn due to traffic but I'm still not able to understand how the remote vpn users can reach the network of the provider on the tunnel that ends on the same interface where remote access vpn is also configured.

  The firewall is asa 5510 worm 9.1

  Any suggestions please.

  Hello

  You are on the right track. Turning U will be required to allow vpn clients access to resources in the L2L VPN tunnel.

  The essence is that the split tunneling to access list must include subnets of the remote VPN to peer once the user connects they have directions pertaining to remote resources on anyconnect VPN

  Please go through this post and it will guide you how to set up the u turn on the SAA.
