8.3 ASA VPN access rules
Hi, I recently bought an ASA 5520 to use as a VPN gateway for several tunnells site to site VPN. I've upgraded to version 8.3, and set up a lab environment. I implemented a simple VPN with a rule of intellectual property general permit to stert with and everything works fine. I'm having trouble tightenign access now, if I change the access on the SAA for ICMP I can ping both directions, if I add tcp I can telnet from a computer at the other end of the VPN, but if I change the tcp protocol to telnet, I can't connect. the other end on the VPN is a cisco 2620XM and I match the lists of access for each of the changes. I also do not understand the meaning of the ASA access list, it seems that if I want to allow the remote tcp host behind the ASA access I have the host behind the ASA as the source, it appears backward? Anyone can shed some light on this? very much appreciated.
Yes, you are supposed to only configure 'IP' to your ACL (ACL applied to your crypto card) crypto and crypto ACL supposed to mirror image on each peer, so when you change to specific TCP/UDP ports, is not mirror image of the other side/peer more.
I thought that you use ACL applied to "vpn-filter".
But in the previous post, actually configure you ACL on each interface.
The above is 3 different ACL you have applied differently (crypto ACL--> apply to the card crypto, vpn ACL--> apply to vpn-filter and your normal ACL interface).

Hello:
I have configured ASA 5505 to acept Cisco VPN Clients on IP-SEC and access internal subnet of tuneling (added a rule exempt NAT too) and the VPN Clients can connect and work without problems.
But no internal network or the ASA I can ping or conect to the VPN Clients.
My configuration:
Internal network: 172.26.1.0 255.255.255.0
The VPN Clients network 172.26.2.0 255.255.255.0
Can you help me?

Raul,
I don't see to apply ACLs inside the interface or as vpn-filter that will prevent the PING of the SAA within the intellectual property to the VPN client.
Are you sure that the VPN client does not have the Windows Firewall on or antivirus software that prevents to respond to PING?

ASDM conc (ASA) VPN access
I have the script like this:
an ASA, which is the FW, TR making static NAT from the public to the private IP and private IP address add is add conc (another ASA) VPN. I am accessing these devices via the VPN client and I get the address IP of VPN pool set on VPN conc. VPN conc. is in a DMZ VLAN, but it also has connection to the local network segment. Purposes of mgmt, I connect to this VPN through SSH conc via a switch in the local network segment. To use the http access, I have to be on one of the servers that are in the local network segment. Since then, when I set up the VPN connection, I'm sure VPN conc., what can do to access http directly from my PC?
This sets up on the conc VPN:
management-access inside
After that you should be able to use ASDM over the VPN tunnel, by connecting to its inside ip address.

Unable to connect to other remote access (ASA) VPN clients
Hello
I have a cisco ASA 5510 appliance configured with remote VPN access
I can connect all hosts on the INSIDE and DMZ network, but not able to access other clients connected to the same VPN.
For example, if I have 2 clients connected to the VPN, customer and CustomerB, with a pool of vpn IP addresses such as 10.40.170.160 and 10.40.170.161 respectively, these two clients are not able to communicate with each other.
Any help is welcome.
Thanks in advance.
Hello
I'm a little rusty on the old format NAT, but would be what I would personally try to configure NAT0 on the 'outer' interface.
It seems to me that you currently have dynamic PAT configured for the VPN users you have this
NAT (outside) 1 10.40.170.0 255.255.255.0
If your traffic is probably corresponding to it.
The only thing I can think of at the moment would be to configure
Note of VPN-CLIENT-NAT0-access-list NAT0 for traffic between VPN Clients
list of access VPN-CLIENT-NAT0 permit ip 10.40.170.0 255.255.255.0 10.40.170.0 255.255.255.0
NAT (outside) 0-list of access VPN-CLIENT-NAT0
I don't know if it works. I did not really have to configure it on any ASAs running older software. There was some similar questions here on the forums for the new format.

Remote RDP client VPN access on ASA 5510
Hello.
We have configured the VPN tunnel from site of offshore to the location of the customer using ASA5510 and access to RDP to the location of the customer. Also been configured remote VPN access in offshore location. But using the remote VPN client, we are able to get the RDP of officeshore location but not able to access to the location of the RDP client. Are there any additional changes required?
Thank you
Hi Salsrinivas,
so to summarize:
the VPN client connects to the ASA offshore
the VPN client can successfully RDP on a server at the offshore location
the VPN client cannot NOT RDP on a server at the location of the customer
offshore and the location of the customer are connected by a tunnel L2L
(and between the 2 sites RDP works very well)
is that correct?
Things to check:
-the vpn in the ACL crypto pool?
-you're exemption nat for traffic between the vpn pool and 'customer' LAN? is the exemption outside (vpn clients are coming from the outside)?
-you have "same-security-traffic permitted intra-interface" enabled (traffic will appear outside and go back outside)?
If you need help more could you put a config (sterilized) Please?

RV042 VPN group &; access rules
I have install a GroupVPN and connect to the RV042 with the client VPN Shrewsoft, works like a charm as opposed to QuickVPN ;-)
The firewall is configured with an explicit deny for RDP access rule to an internal server, can also be used to explicitly a rule is created for certain numbers of IP as a source. I noticed that I need to create an explicit allow rule for the subnet of the client Shrewsoft is using the virtual adapter or I won't be able to access the internal server via RDP through the tunnel of GroupVPN.
Is it normal? I think that establishing a tunnel defies the rules created for a direct access to the WAN port.
Peter
Sorry, I got my signals crossed with my previous suggestion. Your answer has cleared up my misunderstanding. My rule was for a different purpose and it does not work for your situation, I thought it would be.
redirect port (UPnP or redirection) replaced the firewall rules, but does not completely bypass their. He must work around the default rules for work, but don't not past rules customized. The trick is to know the translation of transfer goes first, then when it is processed by the firewall, the destination is the IP and the port internal. In addition, it would seem that VPN works the same way - allows to bypass default firewall but not custom rules.
Since you want to double your security and have a non-standard port MORE limit access to specific IPs through the rules of firewall, then you are set up correctly.
The VPN to bypass the firewall completely? Maybe, but then you wouldn't have the opportunity to clients VPN filter with custom (without a separate section in Firewall VPN) rules. Given that you have created a custom block rule, you must add an allow rule for everything that comes through the WAN (same VPN) port. I agree it's annoying, but that's just the way the program is written.
I didn't test the VPN rules, but I think you can handle this - the only variable would be you allow the public IP address of the remote network or remote LAN subnet range? I expect the LAN subnet.
----------------------
Other thoughts - I personally just use the non-standard port and leave the RDP Security to take care of himself. My clients are very small, so the exposure and risk are fairly low. For a client of profile higher or more secure, I would either put everything inside a VPN connection, or configure as you. Of course, if the security is so important, maybe you should be on a more expensive (and capable) device?

Remote access ASA, VPN and NAT
Hello
I try to get access to remote VPN work using a Cisco VPN client and ASA with no split tunneling. The VPN works a little, I can access devices inside when I connect, but I can't access the Internet. I don't see any errors in the log ASA except these:
1 Jul 04:59:15 % ASA-3-305006 gatekeeper: failed to create translation portmap for udp src outside:192.168.47.200/137 dst outside:192.168.47.255/137
1 Jul 04:59:15 % ASA-3-305006 gatekeeper: failed to create translation portmap for udp src outside:192.168.47.200/54918 dst outsidexx.xxx.xxx.xxx/53There is only one address public IP that is assigned to the external interface of DHCP. The Interior is 192.168.1.0/24 network which is PAT'ed to the external interface and the VPN network is 192.168.47.X.
I think my problem is that the net.47 is not NAT'ed out properly and I don't know how to put in place exactly. I can't understand how this is supposed to work since the net VPN technically provenance from the outside already.
Here are all the relevant config:

public static tcp (indoor, outdoor) https someids netmask 255.255.255.255 https interfaceI can post more of the configuration if necessary.
Change ' nat (outside) 2 192.168.47.0 255.255.255.0 apart ' "NAT (2-list of vpn access outdoors outside)" gives these:
1 Jul 06:18:35 % gatekeeper ASA-3-305005: no group of translation not found for udp src outside:192.168.47.200/56003 dst outside:66.174.95.44/53
So, how I do right NAT VPN traffic so it can access the Internet?
A few things that needs to be changed:
(1) NAT exemption what ACL must be modified to be more specific while the traffic between the internal subnets and subnet pool vpn is not coordinated. NAT exemption takes precedence over all other statements of NAT, so your internet traffic from the vpn does not work.
This ACL:
list of vpn access extended permits all ip 192.168.47.0 255.255.255.0
Should be changed to:
extensive list of access vpn ip 192.168.47.0 255.255.255.0 allow
(2) you don't need statement "overall (inside) 2. Here's what to be configured:
no nat (outside) 2 192.168.47.0 255.255.255.0 outside
no global interface (2 inside)
NAT (outside) 1 192.168.47.0 255.255.255.0
(3) and finally, you must activate the following allow traffic back on the external interface:
permit same-security-traffic intra-interface
And don't forget to clear xlate after the changes described above and connect to your VPN.
Hope that helps.

ASA 5505: VPN access to different subnets
Hi All-
I'm trying to understand how to configure our ASA so that remote users can have VPN access to two different subnets (Office LAN and LAN phone). Currently I have 3 VLAN configuration - VLAN 1 (inside), VLAN 2 (outside), VLAN 13 (phone LAN). Essentially, remote users must be able to access their PC (192.168.1.0/24) and also have access to the office phone system (192.168.254.0/24). Is it still possible? Here are the configurations on our ASA,

Hello
Loss of connectivity to the LAN is not really supposed all remove this command UNLESS your network is using another device as their gateway to the Internet. In this case configuration dynamic PAT or political dynamics PAT (as you) would make sense because the LAN hosts would see your VPN connection from the same directly connected network users and would be know to traffic before the ASA rather than their default gateway.
So is this just for VPN usage and NOT the gateway on the LAN?
If it is just the VPN device I'd adding this
global interface (phones) 10
He would do the same translation for 'phones' as he does on 'inside' (of course with different PAT IP)

Wacky VPN access problem of ASA
Hi people,
I am currenty a situation, and I am in real need of advice...
The situation is that, if ASA helps my remote branches to access my home network and its allowing people to visit Internet inside, its not allowing the remote VPN client VPN access... R V to aid VPN client version of Cisco 4.6...
See a presentation of basic network that illustrates our network and configuration of the ASA...
Advice to solve this problem will be greatly appreciated...
Kind regards
Noman Bari
I see what rou are... Please see my attchement...
Please rate if it helps!

asa himself through site to site vpn access server
Hello
I have problem with access to the servers through site to site vpn to ASA that makes this vpn site-to-site and Clientless VPN enablerd.
Reason why I need it / what I do:
ASA 5510 enabled Clientless VPN and on this Portal allows users to access internal servers through bookmars URL. We use it when someone wouldn't access IPSec VPN or in an internet café. If this user connects to clientless vpn and click on the bookmark to access for example mail server. But there is problem, asa cannot access this server through VPN site-to-site.
Network:
Here's a quick design of my network.
I don't have server access to the problem in the VLAN 159 of VLAN 10, or 100. But I need to be able to access the server in Vlan 159 of ASA 5510, who owns the IP 192.168.1.4.
I have this subnet ASA owned by FRONT-NAT object in the same place that VLAN 10 to 100 are and vpn Site-to-Site profile.
What I makeover or how can I solve it?
Thank you
Clientless VPN when accessing internal servers, it will use the closest to the source of the connection interface and if you connect to via clientless SSL VPN ASA5510 and need access ASA5505 LAN via the site to site VPN, the interface closest to the ASA5510 to ASA5505 LAN is ASA5510 outside interface, therefore, the vpn of site-to-site crypto ACL must match on ASA5510 outside the ip address of the interface.
Here's what you need on each ASA:
ASA5510:
permit same-security-traffic intra-interface
ip 192.168.159.0 external interface allowed access list 255.255.255.0
ASA5505:
ip 192.168.159.0 access list allow 255.255.255.0 host
In addition, also need to add the same ACL for access-list of exemptions on ASA5505 NAT:
ip 192.168.159.0 access list allow 255.255.255.0 host
Hope that helps.

Device behind a Firewall other, ASA VPN
I have a client who wants to put their VPN / behind the ASA ASA main connected to the Internet. Both devices have an inside leg for the internal network, but the ASA VPN connects directly to the Internet ASA.
Topology:
Outisde FW: Internet transfer Procedure > ASA/FW > leg DMZ to ASA/VPN
ASA VPN: Outside the L3 Interface interface DMZ of ASA/FW link
On the outside NAT FW I would be the external address of the VPN / ASA outside the public IP address is available and I have a rule that allows all IP from outside to outside the private IP VPN. Inside = 192.168.254.1 outside = public IP address.
Configured on the VPN / ASA, ASA standard SSL Remote Access.
When I hit the NAT public IP address, nothing happens. I've run packet - trace on the FW outside, and everything seems good.
Someone at - it a sampling plan / config for a similar topology? Internet > ASA/FW > dmz-leg > ASA/VPN
Thanks in advance,
BobCan share you your NAT and routing configuration? Of these two ASAs

Hello world
I would like to ask for help in order to correct a customer vpn tunnel. I'm not familiar with the AAS, so please do not laugh if I write something stupid
So I inherit one asa, which has two interface used physical and vlan more. Outdoors, office, management and management. I use my computer on the vlan management, and I can reach the computers on the desktop (192.168.12.0/24) and the branch (192.168.10.0/24). I would realize that I connect to thrught houses a vpn, and I should reach the 12.x and 10.x network as I was in these networks (due to the microsoft allowed wirewall to the local network traffic).
I inherited a vpn configuration which I added my user.
I'm trying to cite only the relevant portion of config:

I have an ip local pool 192.168.99.100 - 192.168.99.200, but I have the fixed ip with the vpn-framed-ip-address 192.168.99.99 255.255.255.0
Happened when I connect and try to reach the following computers:
I can reach only a freenas 192.168.12.2, and I see in his journal that I have connected with 192.168.99.99 (vpn-framed-ip-address)
I can't reach the computers on networks, however I have two nat rules, working when I'm in the office network 99.0
access extensive list ip 192.168.99.0 nat_management_branch allow 255.255.255.0 192.168.10.0 255.255.255.0
access extensive list ip 192.168.99.0 nat_management_office allow 255.255.255.0 192.168.12.0 255.255.255.0It seems that these two nat rules do not work with my vpn client.
And it is very important to arrive at the asa with ssh through the tunnel, but I can't.
I don't know if that is the ip address of the vpn client is in the management network, perhaps one should change to another network:
for example 192.168.95.0/24
A vpn asa for Dummies or any help is appreciated.
Thank you very much
Hi Chris,
The following should help:
access-list allowed 192.168.12.0 nonat_office 255.255.255.0 192.168.90.0 255.255.255.0
In this way, returning office subnet pool VPN traffic is exempt from nat. And so you will not get the failure of RPF checking.
In addition, you must change this:
nat_vpn_office to access extended list ip 10.10.10.0 allow 255.255.255.0 192.168.12.0 255.255.255.0
(incoming traffic on the VPN remote access would come from the VPN pool.) Not your home network.)
You must have:
No nat_vpn_office access list extended ip 10.10.10.0 allow 255.255.255.0 192.168.12.0 255.255.255.0
access extensive list ip 192.168.90.0 nat_vpn_office allow 255.255.255.0 192.168.12.0 255.255.255.0
NAT (outside) 5 nat_vpn_office list of outdoor access
Hope this helps, and sorry for the delay.

Hello
I have a question concerning the VPN, is it possible to configure the two IPsec VPN site-to-site and remote access vpn on the same ASA and working at the same time, does require one or two different public ip addresses?
I have cisco ASA 5540 - version 9.1
Best regards
Hello
Yes, you can with 1 single public ip address. You need to activate the same-security-traffic allow intra-interface functionality to allow a customer vpn site-to-site vpn access if you need.
Take a look at the Cisco documentation;

Problems to make the access rule for a NAT device work
I am new to Cisco routers so light easy on me.
Our company has just purchased a RV042G so that we can start using VPN for some of our sales representatives. There is always a need to access the RDC to configure our WAN1 port access rule to the internal server. However, it does not work.
I have install this type of rule on Sonicwalls before, but I don't have much experience with Cisco. I'm a bit confused as to why it doesn't work anymore. Any advice would be great.
Service = DRC (3389)
Source port = WAN1
Source IP = our static IP address
Destination IP = 192.168.0.250.
What I am doing wrong?
Hello Eric,
Looks like you got the first step made so fare. How access lists works on this devices is actually just control/allow certain traffic but does not in fact of NAT/port forwarding. What you need to do is then go into the setup and go under transfer. Next, you will create your port forwarding it. You click on service management again to set up which port you must sent (it may be already there for when you have configured your access list). Some of them should be similar on how you implemented in the access list, but if you want more information let me know and I can give more details.
Hope that helps out.
Thank you
