• Bizzare vShield Edge-NAT/VPN problem Post - 5.1 upgrade

  Hoping someone can shed some light on this issue for us - the TLDR is that NAT rules seem to be causing unexpected behavior on the VPN traffic after a vCloud 1.5 to 5.1 upgrade.

  Background: We work with a hosting provider to manage our vCloud environment. Quite simple - 2 ESXi hosts, a few NFS data stores. They have recently updated us of 1.5 and 5.1. For most of our committees, we have just one network of vSE/Routed that connects a subnet to a network of "WAN" and pulls a public IP address from a pool. Send us (NAT network address) and leave (firewall) ports (for example port 3389 for RDP) to the virtual machines selected. Most of these networks also have a VPN tunnel from site to site with a physical Firewall through the internet. After the upgrade, we went and converted our rules to match the period of initial and active INVESTIGATION "multiple interfaces" - effectively subtracts to compatibility mode. Everything was going well (even for devices of vSE always in compatibility mode)

  Question: We first noticed this, when a customer reported that they are unable to access a virtual machine via RDP using it is internal (protected VSE) IP through a VPN tunnel but could access the virtual machine via RDP using its public hostname/IP address. Allow us all traffic between the VPN (firewall has a whole: a rule for VPN traffic). When we connected to troubleshoot (just thinking that the VPN was down), we found that we could connect to any port on the computer through the VPN tunnel except 3389remote virtual. I can ping from the local subnet to the VM troubled on the VAPP network without problem. I was able to connect to other ports that have been opened on the remote virtual machine without problem. I couldn't connect to 3389 through the VPN.

  We thought he could be isolated, but found the question on each VSE we have: If there were a the DNAT rule to translate the inbound for a particular port, this port would be insensitive when traffic through the VPN tunnel that is meant to be the target of the DNAT rule.

  Someone has an idea what could be the cause?

  Looks like it is a problem experienced during the upgrade. These hidden firewall rules will not disappear until the firewall configuration is updated in some way. So go as - upgrade

  (1) upgrade VCD

  (2) update VSM

  (3) to redeploy the entry door to upgrade the edge of the gateway to version 5.1

  (4) convert the firewall rules to the new format (where firewall rules have no management interface or traffic)

  (5) to change the properties of the bridge and the multiple interface mode

  (6) change the specification of the firewall somehow, that is to add a dummy firewall and remove it, turn off, then turn on the firewall, etc..

  Which should cause the deny rule go away

• vShield Networking - configure NAT rules directly in vShield Mnager

  Hello

  I tried to configure a NAT rule to enable access for external network users that is not routable vsphere Client i.e. the plugin for vShield manager to the internal network. I have found no documentation for this. Now, if I place a load balancer it automatically creates a NAT rule. Don't know why I can't do the same thing using NAT exclusively. Someone out there who has done the basic NAT using vShield Edge between 2 distinct networks (L2)?

  I realized what was wrint with my setup. The EDGE is deployed in a lab where we have the internal network, access to the outside, but not the reverse. Thus, we had another gateway on the virtual machine and therefore return traffic never returned to the edge gateway. If it was a problem with my knowledge of NAT.

• VShield Edge Configuration

  Hello

  I recently installed vshield Edge:

  There are two device that have been added to the inventory...

  I set up an internal IP address as my private subnet AND an uplink to have a public IP... and I configured the default Gateway to match my public by default Gateway...

  now I have a machine virtual on my private network that I change the gateway is the IP address assigned to the internal interface of vshield Edge... But it is still not Internet ping!

  Am I missing or wrong configured something?

  Help, please

  Thank you

  Hello

  The reason for two devices could be that you may have installed Edge in HA mode.

  Coming to your network problem, check the following.

  • Check if you have applied the SNAT rule on the external network. In this, the initial INVESTIGATION period should be your private IP network and the translated IP must be one (or) range of your public IP addresses. You must allocate under the IP translated before using NAT.
  • Check if the firewall is disabled (or) added with one exception.

• vShield Edge balancer to load within vCloud Director?

  Hi all

  I had a long week, installation and configuration vCloud Director. So far, it looks great.

  However, I wanted to create a paralytic with 2 web servers and a LoadBalancer (vShield Edge device) in front of them. I just don't seem to be able to find anything about how I activate on the web site of vCloud Director. I can do the NAT and firewall, but balancing is missing ... I'm sure it's there somewhere, I'm just not see it!

  Can someone point me to the right direction?

  Bgrds,

  Finnzi

  This requires the additional license for vShield edge and configure vShield to vCenter PLugin.  There is no user interface in vCD interface to configure the load balaning VSE again.  1.5 introduces the possibility to configure VPN (if authorized), through vCD, but not the LB function again.

• Clarification of the NAT rules

  Hi all

  I understand the notion of NAT and why it is used.  However, I am a little confused given the following command:

  object network obj-internal

  nat (inside,outside) dynamic interface

  Please correct me if I'm wrong, but until now, I understand that this command creates a network called "obj-internal" object and creates a rule for traffic from the interface inside of the external interface.  However, I'm confused with the dynamic interface part.  Could someone please elaborate more on the meaning and usage of this part?  Any help is greatly appreciated.

  To create an object you also a definition of what is this object. You also need somethng as a host or a subnet statement.

  For this object that you want to specify how to resolve the internal IP address (inside the network) are translated when communicating with the external network. The NAT command in your example uses a dynamic conversion (unlike the static NAT which is generally used for outside - inside the traffic, or when an inside host should always get the same IP address to the outside) who always uses external IP of the SAA. So no matter what internal host communicates with the outside world, they all appear with a single IP address on the destination system.

• VShield edge Nic

  Hello world

  I installed VSphere 5.5, 5.5 VCloud and VShield 5.5 for a test. Everything seems fine. But when I create an organization VDC and add an EDGE gateway for him, the automatic system create a VM VSE under "system vDC". Virtual machine contains multiply network cards, including two he uses for the external network and the Organization's network. But there are still many that connect to a standard switch named 'None '.

  Although it works well, the problem is I can not migrate or do his host in maintenance mode. During the migration network interface adapter, it shows"2 use 'none' network, which is not accessible. »

  Does anyone know something?

  Thank you

  This should be a non-issue.

  Each vShield edge device has 10 NIC cards.  One will be attached to a given network (an external, one internal).

  The 'None' network, a group of port assigned.  This does not block vMotion does not happen, and I was

  Even if you get one! ------warning message, you should still be able to click Next and complete the vMotion.

  The only way you would be blocked from vMotion is if one of the two real networks were somehow connected to a specific host.

  Can you provide a screenshot of it with the next button grey and everything that is not a warning to the network no?

• Cannot delete a NAT rule

  Hello

  I make a mistake typing in CLI a NAT rule and I can't delete it because this tells me is that it is used...

  An idea for there remedy?

  Thanks in advance,

  Hello Romain,.

  I'm really not an expert on IOS, but I found cel on Google don't know however if it works:

  "You may need to remove the nat inside and nat outside interface command, and then clear the translations until you can remove it. "This is an example of SDM:

  interface Ethernet0
  no nat inside ip
  output
  interface Ethernet1
  No external ip nat
  output
  do not delete ip NAT. forced translation
  no nat ip inside source static tcp 172.16.5.2 interface Ethernet1 3389 3389
  interface Ethernet0
  IP nat inside

  Nice day.

• Asymmetric NAT rules

  I am trying to configure another ipsec VPN group and political.  So far, I can communicate with her, and I can ping the ASA 5505, but nothing else inside.  The funny this is that I have another configuration group and the policy that works very well.  I tried to imitate him, but I can't understand what I'm doing wrong.  I get this error in the log:

  Asymmetrical NAT rules matched for flows forward and backward; Connection for icmp src, dst outside: 10.4.71.104 inside: 10.4.70.2 (type 8, code 0) rejected due to the failure of reverse NAT.

  A network diagram is attached.  Thanks for your help.

  Andy,

  Yes 8.3 makes a difference

  Well I can suggest a few ways out of it.

  And that's what you need to add... kind of nat provides previous versions.

  NAT (inside, all) source static obj - 10.4.70.0 obj - 10.4.70.0 destination static obj - 10.4.71.0 obj - 10.4.71.0

  Edit: fixed IP addresses. If 10.4.70.0/24 is local and remote 10.4.71, you need to add an exemption here.

• Extracting rules from PIX 515 (PIX Ver: 7.0)

  Hello

  I have a lot of access configured in my PIX515 rules and since I am not the person responsible for this firewall from the beginning, I'm getting lost with all theses rules...

  I see a place that you can ' extract to ' rules and for each rule, how many times the rule was used...

  for example:

  3 tcp any any eq www (856)

  4 udp any any eq field (732249)

  etc.

  With this, I can find the rules that are not used...

  Do you know how I can do? (get statistics of the thesis)? Should I use a software or is there a command in the PIX for this specific information?

  Thank you in advance for your help!

  Just run the following command in the commnad line interface.

  See the access list

  You want to be behind each line the number of hitcoult that indictes how many times that ACL has been reached.

• helps the nat rule

  Hello

  I try to create a second VPN connection on our companies cisco PIX. It almost works, but I'm having problems to make the nat rules to work for two virtual private networks.

  The config is attached, but the key areas are below.

  Access extensive list ip 192.168.60.0 LeasedLine_20_cryptomap allow London 255.255.255.0 255.255.255.0

  LeasedLine_40_cryptomap list extended access permitted ip object-group LAN_subnet-group of objects InsightLAN

  NAT (inside) 0-list of access LeasedLine_20_cryptomap

  NAT (inside) 101 192.168.60.0 255.255.255.0

  NAT (DMZ) 101 172.30.60.0 255.255.255.0

  NAT (GM3) 101 192.168.70.0 255.255.255.0

  card crypto LeasedLine_map 20 corresponds to the address LeasedLine_20_cryptomap

  card crypto LeasedLine_map 20 set peer 161.xxx.106.34

  LeasedLine_map 20 transform-set ESP-3DES-MD5 crypto card game

  card crypto LeasedLine_map 40 corresponds to the address LeasedLine_40_cryptomap

  card crypto LeasedLine_map 40 set peer 213.xxx172.253

  card crypto LeasedLine_map 40 value transform-set ESP-AES-128-SHA

  The problem I have is with the nat 0 command (inside). If I add the command

  NAT (inside) LeasedLine_40_cryptomap 0-list of access VPN 2nd (insight) works, but the first stops working.

  Can someone help me get this to work?

  See you soon,.

  Al

  Hello

  You can have several configurations that have "(inside) nat 0 access-list"

  Instead, you use a simple ACL to set the traffic you don't want NAT. Or for which you want to NAT0.

  If you can do this for example

  the INTERIOR-NAT0 extended ip 192.168.60.0 access list allow London 255.255.255.0 255.255.255.0

  access list to the INSIDE-NAT0 extended permitted ip object-group LAN_subnet-group of objects InsightLAN

  NAT (inside) 0-list of access to the INTERIOR-NAT0

  And the two connections should work perfectly.

  If you arrived to set up a third-party VPN connection for example you would simply add another line to the same LIST.

  Hope this helps

• SSH on vShield Edge using Java CCES

  I am trying to connect to vShield Edge using jsch for SSH connection library.

  Connection to a linux server it works perfectly, but connected to the vShield edge server, the output is:

  vtysh: invalid option-'c '.

  Try "vtysh - help ' for more information.

  What it means?

  The connection seems to work correctly, I think the problem is the command I want exec ('list' command).

  I tried many commands, but I always have the same answer.

  I also used this methos Java to set the Pty:

  Can I define another type?

• Problem assigning vShield edge licenses

  We have a cluster running vCenter 5.1 standard with 3 hosts ESXi 4.1 under license with vSphere 4 Enterprise Plus keys. Recently, I've deployed a vCloud Director 5.1 with a Manager Server 5.1.2 Server vShield. I was able to successfully add the vCenter vCloud and vShield Manager. Then when I try to add our license of vShield edge in vCenter as the installation guide document, I can't find the CIS or POSSIBLE asset in vCenter section "permit". Is it because we lack of vSphere 4 license?

  

  The problem is now resolved. Recently, we are improving our vCenter 4.1 to 5.1. The appliance Manager vShield was installed before the upgrade. After the upgrade, I didn't perform a reboot of the vCenter server. Once I restarted the server vCenter, he was able to found the vShield active Edge of the appliance Manager vShield.
