Cisco VPN :: 5520 - Can't Access Internet
Jun 7, 2012
I'm trying to setup a very basic EasyVPN from my ASA 5505 (home/client) and ASA 5520 (work/server/ IP 74.25.12.245). Everytime when I enable 'Easy VPN Remote' on my ASA5505, my home PC get disconnected from the internet.
My ASA5505 client gets dhcp IP address (private IP 10.1.1.79) from my cable modem. I believe my cable modem has this public ip 50.54.12.224.
I looked at the logs on my ASA 5520, it seems that all the requests from my ASA 5505 client are going thru and connected. And similar with ASA 5505's log.
Between 74.25.12.245 and 50.54.12.224 (user= home) has been created.
IPSEC: An outbound remote access SA (SPI= 0xA0319409) between 74.25.12.245 and 50.54.12.224 (user= home) has been created.

I've got what is probably a very basic question - but i can't figure it out.I have: Internet (ADSL) -> 2851 (ADSL wic) -> 5520 -> internal LAN (192.168.1.x/24)
The asa has just replaced a Checkpoint firewall.I've set up the ASA to the point where all hosts on the internal LAN have internet access (using a dynamic PAT on that network). This all works well.
The problem i have is i am trying to allow access from the internet to an internal host on a specifc TCP port (as i had done on the Checkpoint) but i'm getting:
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src outside:111.111.111.11/52135 dst inside:192.168.1.252/5555 denied due to NAT reverse path failure
From what i have read i need to add a NAT exemption for this particular use case - to avoid the dynamic NAT i have setup, but im not sure how to do so.I'm running 9.1 on the ASA, no VPNs yet. Just this basic setup.

I am new in ASA, I have the DMZ (10.1.1.0/24) configured on ASA 5520 and I achieve the reach Internet from DMZ (10.1.1.0/24), but now need reach DMZ from inside (172.16.12.0/24) and inside (172.16.12.0/24) from DMZ (10.1.1.0/24), in other words round trip.

ASA 5520 to get it to authenticate VPN users against and Active Directory environment plus allow management access as well. I created a Dynamic Access Policy on the ASA stating that if you are a member of the Active Directory group "Managment" the continue. I chagned the DefaultAccessPolicy to "Terminate". So with that, VPN users cannot connect because they are not a member of that group, but the access to manage the ASA is allowed because of that policy.Is there a way through using Dynamic Access Policies that I can allow management access (SSH, ASDM, etc) by matching to a group membership and will allow normal users to VPN in successfully but not allow them access to managing the ASA?

We have a Cisco ASA 5520 with the VPN Plus License and 8.04 IOS installed, we want to set up vpn access to our users. We can use the Cisco VPN client which works on Windows Platform, but we also have MAC OS 10.7 which works only with Cisco Any connect.
I am a little bit lost with all the client and the license, actually we can't setup more than 2 vpn session with an Any connect client installed on MAC or Windows. The authentication is by Certificate, the first two connect fine, but the third one don't connect and prompt for a username / password. I joined a SH VER of my ASA, what is wrong on the license or perhaps it's a configuration problem?

We have a Main ASA 5520 and two remote site ASA 5505's that connect to each other via S2S VPN tunnels. Currently they are doing split tunneling, so only local traffic goes over the tunnel. We have are local LAN (10.0.0.0/16) and our DMZ (10.3.0.0/24) network at the main site. The DMZ hosts our external sharepoint, but we have access to it internally The problem is site A (10.1.0.0/24) and site B (10.2.0.0/24) have no idea of it, and when attempting to go to the site, it fails. You can access it via the external site address, but that's the only way. Normally the external address is blocked when you are internal.What i'm stuck at is even when we had all traffic sent from Site A to our main hub, it still wouldn't find it. Would i have to make a separate vpn tunnel purely for that DMZ traffic?

I am trying to configure Remote Access VPN in our Cicco ASA 5520 firewall through SSL VPN wizard. I tried to configure Anyconnect VPN client option, but after entering user/pass it gives error "An error was received from the secure gateway in response to the VPN negotiation request. Please contact your network administrator. The following message was received from the remote VPN device: No assigned address"
As looking online there is no easy step-by-step option for same. I want to provide Remote Access VPN to some of our user abroad who should have access to few server applications and no internet access.

I have a Cisco 5520 using ASDM 6.4
Currently my VPN settings use a shared key without certficate to access the VPN. I would like to now set up a self assigned certifcte from the ASA to get users to import the certficate in order to VPN..

I just configure an ASA 5520, here is the config (the ip address of outside network if going to change from private direccion by reason security).
The problem that I have is the users can access to the web site through the public´s ip address but they do not can access through by name. We review all the config on the server DNS and with the command NSLOOKUP we can see that work fine. The client think that the asa is blocked the connnection.

I have setup clientless SSL VPN on my ASA. User authentication is done by RADIUS using ACS 5.2, I have created two portal one for IT department and the other for auditing department but the user in auditing if the select IT group from the drop down list they can login to it, my question is how can I make them login to their group only and prevent them from accessing other groups ?

I have an issue where my vpn clients are unable to access certain vlans in my network.I have configured an ASA 5520 with VPN access using the wizard and using the ASA as a dhcp server for VPN clients. I find that this allows the clients to access server resources such as the Exchange and Domain Controller but I find that these vpn clients are unable to ping each other as well as certain vlans that I have.Is there a way to configure the ASA to use a particular vlan that is already configured on the core switches?If I create a vlan interface and set the IP of it to 10.50.x.x then the vpn clients are suddenly unable to connect to any network resources...

I am trying to build a remote vpn in ASA 5520 Software Version 8.3(1). I am using ASDM 6.3(1) for the configuration. I went through the SSL VPN wizard and did the configuration. I tried connecting to the ASA using anyconnect VPN and I could successfully connect the VPN. My home laptop takes an IP 192.168.60.21 (which I have defined in the wizard). Now my issue is, I can't access any office internal network from this laptop (none of the internal IP is ping ing even). Meanwhile, I could ping and rdp to this laptop(which is connectd by anyconnect VPN) from my office network. One thing I noticed is that when I give a traceroute to an internal IP from the laptop, the first hop goes to my home ISP router.

I am new to v5.3, and I am not good at VPN.I just have my consultant to configure this correctly just today. Currently, there is only one rule for the access policy (Single Result Selection). That rule is to use Active Directory as the source for the authentication. And by default will deny any other access which is not found in the rule.Now... I just got an order that I need to setup a new user who will need to access to our network by using Cisco IPSec VPN (the software one). But that user is not setup in our Active Directory, and we do not want him to access our domain anyway. He only needs to access non-domain resourse...such as airconditioning controller by IP. So I am thinking to setup his account by using "internal identtity". If I do this way, what do I need to do to setup another access policy? May you give me some steps with little more details? OR... if it is not the way I should do...what else can I do to achieve this goal? Also, he said he could provide his static IP trying to access from. I have a ASA 5520.

We have an ASA 5520 in HA. (version 8.X upgraded to 9.1 (1))We used Wizzard to configure VPN clientless and portal. Also, configured manually we have the same issue: We can access to the portal using IP address of Lan interface but not with outsides (2 ISP). The clientless VPN is enable on the public interface and no packets rejected in logs.We try to modify the Crypto map created by default to replace "any" to "any" by "any" to "our public IP" (We see that is recommended by Cisco) It works for 10 minutes.(strange..) but after 10 minutes the active member crashs.. only a reboot with previous configuration was good.We try to investigate but each time we modify Crypto maps, the firewall is going bad.

I am configuring an ASA 5520 for VPN access. Authorization & Authentication use an LDAP server. I have the tunneling configured successfully, and I can access internal resources. What I want to do now is to restrict access to a specific AD Group membership. In the absence of that group membership, a user should not be allowed access to the VPN.
My test VPN client software is Cisco Systems VPN Client Version 5.0.05.0290. The group authentication is configured into a Connection Entry that identifies the Tunnel Group. I think I worded that correctly.
The Software Version on the ASA is 8.3(1).
My current challenge is getting the VPN to stop letting every access request through regardless of group membership.

The configuration (AAA LDAP, group policy, and tunnel group) is below.

We have 2 5520 ASA's working in an active/standby function at our central site. The remote agencies have control of their ASA's or other devices able to create VPN tunnels back to the central site. When a new remote agency wants to connect to our central site we assign them a network range that is routable on the central sites network.We ask that the remote agency NAT into the addresses we provided them.This way we are able to route back to them. We assign the interesting traffic and then they we start communicating by way of the tunnel.
Since the central site can't control the traffic coming in on the site to site tunnel other than just defining the interesting traffic AND we aren't able to control the NAT on the remote end how can I put an access list on the central site ASA to allow only certain ports and IP's by way of access list? Ultimately, I'm trying to limit traffic on the central site coming inbound to only allow traffic I want. I tried applying a group policy to the lan2lan site to site tunnel, but it failed for some reason. It actually prevented all traffic. Can I apply a group policy to a site-to-site tunnel?
I'm struggling here a bit as I don't have control of the remote end. They can NAT whatever they want to an address in the range we assigned them. The tunnels interesting traffic is set to full ip to the central site's destination. The interesting traffic on the central site is set the same. However, on the central side...I want to limit that traffic to only certain ports by way of an acl. If it is possible to assign a site-to-site tunnel a group policy and filtering is done in that method, can

We are moving from a different vendor to ASA 5520s. So far my "training" for Cisco consists of s Cisco press book, some white papers and guides, this website, and a bunch of mistakes. So, I have what is probably a pretty basic question for most folks.
What is the difference between Firewall Access Rules and ACL/ACE? And when to use which?
for example: on my ASA 5520s I've set up an Interface for my internal LAN: 172.16.x.x., a DMZ 192.168.2.0/24, and an interface for the Internet side. The 5520 is set up as a routing firewall betwen my internal lan, DMZ, and Internet.
If I want to allow my internal users Internet access for http and https would I use a Firewall Access rule?For most of my rules allowing outbound access from my 172 LAN and DMZ and inbound access to devices in my DMZ can I mostly utilize the Firewall Access Rules?

I'm trying to set-up 3 remote access groups on an ASA5520 running version 8.4(3) software so that remote clients connected via Cisco VPN Client can also access spoke networks which are also connected to the ASA. I've previously set this up on ASAs running v7.2 software without issue but don't seem to be able to do the same here and can't for the life of me figure out what's wrong!
I have set-up the 3 remote access groups:
Group 1 - subnet 192.168.1.48/28Group 2 - subnet 192.168.2.0/25Group 3 - subnet 192.168.3.0/25
My remote access user groups can all connect to the head office subnet (10.0.0.0/8) without issue. But only one of the groups (192.168.1.48/28) appears to be able to access the spoke sites (172.30.10.0/24 and 172.30.20.0/24) that I have set-up. However, I can't see what the difference is between the 3 groups I have configured so can't understand why it works ok for one group and not the others?
When I use the packet tracer, it tells me that the flow is being dropped at the VPN encryption phase but why is that? How can I find out more? Here's the relevant config on my ASA:
!same-security-traffic permit intra-interface!crypto dynamic-map remoteuser 5 set transform-set ESP-3DES-MD5crypto dynamic-map remoteuser 5 set security-association lifetime seconds 28800crypto dynamic-map remoteuser 5 set security-association lifetime kilobytes 4608000!crypto map outside_map 65000 ipsec-isakmp dynamic remoteuser!ip local pool pool1clients 192.168.1.49-192.168.50.54ip local pool pool2clients 192.168.2.1-192.168.2.126ip local pool pool3clients 192.168.3.1-192.168.3.126!access-list split-tunnel-pool1 standard permit 10.0.0.0 255.0.0.0 access-list split-tunnel-pool1 standard permit 172.30.10.0 255.255.255.0 access-list split-tunnel-pool1 standard permit 172.30.20.0 255.255.255.0 !access-list split-tunnel-pool2 standard permit 10.0.0.0 255.0.0.0 access-list split-tunnel-pool2 standard permit 172.30.10.0 255.255.255.0access-list split-tunnel-pool2 standard permit 172.30.20.0 255.255.255.0 !access-list

I have Cisco ASA 5520 / ASA Ver: 8.0(4) / ASDM Ver: 6.1(3). I have configured Remote Access VPN and everything seems to be fine. Like i have created Extended ACL and allowed for singe host with particlar port to be allowed.
After login with the Anyconnect client, i am restricted to access the single host configured, but not based on ports. i.e. i do not want user to RDP the server allowed, but only access the application based on the port that is allowed. But somehow it is not working.
how can i allow user to access a server with defined port only and not any other service/port access for the server.

I have a site to site VPN between SiteA to SiteB which is working fine. SiteA has an ASA5520 and SiteB Pix501. The ASA5520 is running version 804 with split tunneling. Users connect to SiteA using remote access VPN. Is it possible to setup SiteA ASA5520 so that when users connect to SiteA they can access servers located on SiteB through the tunnel? I know i can setup the Pix501 for remote access VPN but it is located in another country and i don't want to take a chance just incase i lose connectivity.

I have an ASA 5520 8.2(3) and allowing my remote client-to-site-vpn clients to access resources directly connected to my ASA on separate lower security interfaces (not the outside) besides just clients on my internal networks. Someone mentioned to me configuring 'VPN on a stick' however from what I've read this seems to be only applicable when it comes to split-tunneling back out the outside interface (could be off on that). Is this possible on other lower security interfaces as well, and if so what would a mock config that accomplishes that look like (acl's, nat, etc)? Also, if I want internal users to be able to connect to these remote clients once they are active, are there any nat statements necessary (such as nonatting them) or are the vpn clients just seen as internal clients from the rest of the internal network's standpoint by default?

I have created a new sub-interface on our ASA 5520 for guest internet access.
My goal is to allow access to a few specific services hanging off some dmz interfaces on the same firewall and full unrestricted access to the internet only. Everything else should be out of bounds.
The order of the rules I plan to setup on the guest interface inbound are:
#1. <rules to allow access to specific services in the dmz>
#2. <block any ip access to the entire private network ip address space>
#3. <permit ip any any>
#1. These rules will give access to the guest user to services located in the dmz
#2. This rule will block all access to any services in the private ip address space (thus blocking access to all internal services)
#3. This rule is to allow access to any other services i.e. the internet.
Is this the best way to achieve my goal in the most secure way or is there a better way? i.e. is there a way to force the traffic by default to only go out the outside interface unless there is a specific rule allowing it go elsewhere?
(Of course Dynamic PAT will also be configured for traffic coming from the guest interface to the outside interface.)
