• SSL VPN using ASA 5520 mode cluster - several problems

  I configured 2 ASA 5520 s in the load balancing cluster mode. I connect using anyconnect and I download the customer the first time and everything works well except outlook. I don't know why outlook does not work.

  The second problem is after the anyconnect client is installed on your machine, he remembers that ASA (say ASA2) he first connected and the GUI shows the address IP of ASA2 instead of the virtual IP address of the cluster. I want users always connect using the virtual IP address.

  The third problem I have is there is a default group of SSL VPN and I want all users to use this group. In the initial web page, there is a drop down menu which shows that this group, but I still want to disable this menu drop-down.

  Any suggestions?

  To disable the drop-down menu, you can turn it off with the command

  WebVPN

  no activation of tunnel-group-list

  This will take care of your last issue.

  ***************************

  You can create a profile of the Anyconnect client with the name of the server you want to connect with and that make the ASA that will solve your problem of virtual IP.

  **************************

  Regarding Outlook, do you use specific ports which allows inspection of the ASA. Take a look at the list of inspection on the SAA and perhaps try to disable inspection and see if it works.

• Using Cisco Client to site VPN on a behind a NAT ASA 5520

  I apologize if this has been asked and we answered in the forums.  I looked, and while I found a large number of entries that were dancing all around this question, I never found nothing which addressed this specific issue.   We currently use an ASA 5520 as the head end of a relatively large customer to site IPSEC VPN (approximately 240 users, not consecutively).   This ASA is currently sitting behind a Checkpoint firewall with a real publicly addressable IP address on its public interface.  All of our customers use the legacy Cisco VPN (not the one anyconnect) client.  We plan to a few controllers F5 link set up between ISPS and firewalls.   For VPN connectivity F5 recommends that we NAT IP address (called a broad IP) to point back to a private IP address on the ASA and F5.  My question is, will this work?   I've always heard say that the head of line needed to have a public IP address on this subject because this is what will be placed in packages for the client to respond to.

  For further information, here's what we have now and what we are invited to attend.

  Current

  ISP - router - firewall-fire - ASA (public IP address as endpoint)

  Proposed

  ISP - router - F5 (public IP address as endpoint using a NAT to ASA) - Firewall - ASA (10.X.X.X as its external interface)

  Proposed alternative

  ISP - router - F5 (public IP address as endpoint using a NAT to ASA) - ASA (10.X.X.X as its external interface)

  All thoughts at this moment would be greatly appreciated.   Thank you!

  Hello

  If there is a static NAT one by one on F5 to the external interface of the ASA, then I don't think they would be any problems.
  Because when the client will attempt to connect to IKE to the translated public IP, F5 will redirect the request to ASA outside interface that is configured for the VPN.

  In addition, to ensure the udp500, 4500 and esp is allowed and then you should be good to go.

• ASA 5520 - VPN using LDAP access control

  I'm setting up an ASA 5520 for VPN access.  Authorization & authentication using an LDAP server.  I have successfully configured tunnel, and I can access internal resources.  What I want to do now is to limit access to a specific ad group membership.  In the absence of this belonging to a group, a user cannot access the VPN.

  My VPN client software testing is Cisco Systems VPN Client 5.0.05.0290 Version.  The Group authentication is configured in a connection entry that identifies the Group of Tunnel. I think I wrote that correctly.

  The Version of the software on the SAA is 8.3 (1).

  My current challenge is getting the VPN to stop letting each request for access through little matter belonging to a group.  I found the thread below to be significantly useful, but there is obviously something which is not entirely mesh with my situation.

• Routing with Cisco ASA 5520 VPN

  I have installed IPsec vpn remote users in the Cisco ASA 5520 using RADIUS in my main network. Works very well. I have a site to my Cisco ASA5520 tunnels going to other sites, some of the tunnels have Cisco ASA and some have SonicWalls. I wish that my users VPN remote IPSec to be able to navigate in these tunnels is a site to access remote subnets attached to these tunnels. Do I need to use a combination of routing and the ACL? Or can I just use ACL only? Or just use routing only?

  Thank you

  Carlos

  Hello

  The key to set up here is the two ACL of VPN L2L end points that determine the 'interesting' traffic to connect VPN L2L. You will also need to confirm that the connection of the VPN Client is configured so that traffic to the remote sites have sent to the connection of the VPN client. There are also other things that you should check on your ASA plant

  Here most of the things you usually have to confirm

  • Set up 'permit same-security-traffic intra-interface' if it is already present in your configuration
    • This setting will allow connections to form between the hosts that are connected to the same interface on the ASA. In this case, applies because the VPN client users are connected to the interface 'outside' of the ASA and also remote sites are connected to the ASA to "external". If the traffic between the remote VPN Client and VPN L2L sites will be to enter and exit the same interface
  • You will need to check how the customer if configured VPN connection. Split or full Tunnel tunnel
    • If the connection of the VPN Client is configured as Split Tunnel then you need to add all the networks from the remote to the Split Tunnel, so that the connections between the VPN Client is transmitted to the ASA and from there connections VPN L2L
    • If the connection of the VPN Client is configured as full Tunnel, then there no problem that all traffic is transferred to the Client VPN connection all its assets
  • Define the VPN pool in the ACL of VPN L2L
    • You should make sure that the pool network VPN Client is defined in the ACL that define 'interesting' traffic to connect VPN L2L. So, you need to add the pool VPN VPN L2L configurations on the sites of Central America and remote control
  • Configure NAT0 / NAT exempt for remote VPN Client to L2L VPN Site traffic at both ends of the VPN L2L
    • You must ensure that the NAT0 / exempt NAT rules exist for the VPN Client for Remote Site traffic. This will have to be configured on the SAA "outside" interface. Format of configuration varies naturally a bit on the ASA Central his software level.

  These should be the most common things to set up and confirm for traffic to flow between the VPN Client and Remote Sites

  Hope this helps please rate if yes or ask more if necessary.

• Tunnel VPN ASA 5520 (DMZ + INSIDE) destined for OUTSIDE

  I can't find any reference to anywhere else.

  We have an ASA 5520 to our site HQ (inside the network) with several regional subnets on the DMZ interface.

  We need connectivity VPN Site to Site between the INSIDE and a remote control on the OUTSIDE of the site, as well as between the DMZ subnets and even outside the site. The interface from the OUTSIDE of the SAA must be local VPN endpoint for all tunnels.

  I created a S2S VPN between the INSIDE and the OUTSIDE site and it works great.

  When I create a VPN S2S tunnel between a site of DMZ and even outside the site (using the same settings the and remote, but with a cryptomap different because the local subnet (DMZ) is different from the other inside the subnet, the traffic gets the mapping (show crypto isakmp his) to the same cryptomap that was created for the access to the tunnel from the OUTSIDE) , instead of to the new cryptomap, so remote endpoint deletes it, and traffic also causes SPI incorrect of for the remote endpoint, which makes the original INTERIOR outside OF THE VPN tunnel to fall from time to time.

  Is this a bug?

  I also did a local S2S VPN tunnel configuration test of networks as everything INSIDE and the DMZ. With the help of the wizard VPN S2S leads ASA only to create a NAT rule exempted for the subnet on the INSIDE interface. Can I manually create another tax-exempt NAT rule to the side of the DMZ and use this a S2S tunnel to connect sites inside and DMZ to the remote OFF-SITE in a connection profile?

  I'm building a Rube Goldberg?

  Thank you

  George

  Hi George,.

  It seems you have a situation overlapping it, are you sure that subnets inside did not overlap with the networks from the DMZ?  A package tracer could clarify wha that the ASA is actually sending.

  In addition, you can merge the two interfaces on the same card encryption if you wish, just make sure that the NAT is configured correctly.   For example; Source NAT (all, outside) static...

  The VPN is OK? ("' isakmp crypto to show his" should show a MM_Active tunnel to the peer address ")

  Normally exempt us VPN site-to-site of NAT traffic. This could be your problem. If you can share your configuration, we can have a look.

  p.s. you should affect the question of the security / VPN forum.

• With an ASA 5520 port forwarding

  Hi all

  I recently bought a Cisco ASA 5520 on eBay for study and I decided to only use it as a firewall between my home LAN and Internet. Wow, what a learning curve! I managed to add my internal networks as objects and create a rule (thanks to youtube) NAT to PAT my internal devices out of the Internet with ASSISTANT Deputy Ministers, but I am really struggling to do the following:-

  -allow all incoming traffic that hits the outside interface for port 38921 and nat at 10.1.10.101:38921

  -allow all incoming traffic that hits the outside interface for port 30392 and nat at 10.1.10.101:30392

  External Burba: tcpdump - ntpi em1 port 25

  You can use the iplog command to capture a PCAP file on the module AIP - SSM (assuming that you sent the traffic you with capture or through the module AIP - SSM IPS). It will capture based on the source IP address.

  If you want TCPdump granularity, make a service account on the sensor, open a session in the Linux system, able to root and tcpdump away.

• ASA 5520 DRAM Upgrade

  Hello

  We have an ASA 5520 running the 8.x version which currently has 512 MB of DRAM.

  I would like to upgrade memory 1 GB DRAM

  Issues related to the:

  1 how many slots slots DRAM the 5520 there?

  2. I found this part:

  http://www.MemoryX.NET/asa5520mem1gb.html

  Seeking to be good. Is there anywhere I can OLA to be sure? I was looking and looking, but I can't find any hard documentation about the DRAM modules, I can use for my 5520.

  Thank you 1 million,

  Pedro

  There should be four.

  The only supported memory upgrade must come from Cisco ASA5510-MEM-512 = manufacturer

  There is no 'Cisco' part number to memoryx in the price list of Cisco. Also I think it's for the AIP, not the chassis module. I think that the chassis only supports 512 MB chips. The link below is the one you want.

  It shows that he have a single good Bank. I have not a 5520 in lab to take a look, but the documentation must be accurate.

  I have an ASA 5520 and master mechanic wants me to a login account via CLI that the helpdesk will just display but makes no changes. I can do this, or what I need to use the ASDM software. Thanks in advance and have a nice day

  Follow this example in link, specific scenario you need, simply create local account in asa with the privilege level 5... see link PLS.

• ASA 5520 8.0 (4) port depending on the ACLs vpn works not

  Hi all

  I have a problem with an ASA (5520 8.0 (4)) for lack of working with a port based acl for remote clients. I have a simple acl from a single line to split traffic, if I allowed the tunnel IP works fine, if I lock it up to TCP 3389 rdp will not work. I don't see anything in the logs and debug output, I did have a problem with a similar configuration (5510 8.0 (4) and I'm at a loss to explain it.)

  Everyone knows about this problem before? I have nat exclusions etc and as I said, the tunnel only works if the acl permits all IP traffic between client and server.

  THX in advance

  Split-tunnel list cannot IP, if you want to restrict which ports are are sent via the tunnel vpn for your clients vpn, you need to use VPN filters under Group Policy:

• ASA 5520 and MPF

  Hi all. In our company we have recently upgraded our PIX 515 firewall to ASA 5520, and we started to live a thing strange event. On one of the sites we host, I saw a lot of outdated SSM messages popping up and I think that they are the source of the problem when they surf the site (mainly surfing works fine, but sometimes people cannot content etc.).

  I found the Cisco solution for this problem by using the MPF, but one thing confuses me. If I ask a MPF allowing adults MSS on the external interface of the ASA does this political conflict with the comprehensive policy that is on the SAA by default or can they both at the same time?

  Thanks in advance for any help.

  You can have a single policy per interface and another - global, that by default applies to default-inspection-traffic.

  See http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/mpc.html for more details.
