VPN Internet access ASA5520
Now my VPN works fine, it connects the user to the network, but it prevents them from using the internet.
How can I set ASA5520 to force users to use their staff internet vs. Internet companies through the VPN tunnel?
I agree with Jay's advice on the implications of the split tunneling and the potential threat to your network.
With the ASA and 7 code version you aren't necessarily need to proxy server. In PIX code pre 7 versions the PIX would not transmit on the same interface, happened on the traffic. With version 7 (also good for PIX and ASA) code, it is possible to configure it so that it will transmit to the interface on which it was received. So even if a proxy server can be a good thing he is most needed.

Hello
You could start by adding the following configurations
permit same-security-traffic intra-interface
This will allow traffic to the VPN users access the interface ' outside ' of the SAA and to leave to the Internet using the same interface ' outside '. Without the above command, it is not possible.
Also, you need to add a NAT configuration for VPN Client users can use the Internet connection of the ASA
To do this, you can add this command
NAT (outside) 1 172.16.0.0 255.255.0.0
This will allow the PAT for the Pool of VPN dynamics.
Hope this helps

Hello Jose,.
I see that you use LOCAL authentication, what you can do is, you can create another political group and link this political group for the user name, example:
attributes of group PALLET policy
Split-tunnel-policy tunnelall
name of User1 user attributes
RANGE of VPN-group-policy
The other username will use hw_policy, since it is the default value for the tunnel-group hwclients.

No internet access through VPN
Hi, I have the router Cisco 881 (MPC8300) with c880data-universalk9 - mz.153 - 3.M4.bin when users establish a VPN connection to the corporate network, had access to all the resources but no internet access, please help me what else I need to configure to achieve my goal. I don't want to split the tunnel, internet via VPN, users must have. In my opinion, I have put an additional configuration for NAT, but my router not recognize u-Turn and NAT commands on the object on the network.

Even IOS VPN Interface Internet Access issue
Hi all
I was wondering if there was any equivalent to these orders of ASA 5510 to put on a cisco IOS router 2811.
Split-tunnel-policy excludespecified
value of Split-tunnel-network-list LOCAL_LAN_ACCESS
What I want to achieve is to give internet access to my vpn users without creating a split tunnel, which means the vpn user turns off the Internet on the same interface on that their vpn router ends.
Is a 2811 for this there docs? I could not find the doc for it...
TIA,

Client VPN prevents internet access from other computers on the network
Hello.
I run Client ver 4.6.03.0021 from an office on a network of 11 computers via a hub 16-port. Internet access is through an ICS gateway to the cable modem. Once I changed the modem cable to test a backup and then switched back to the original modem. After this, only computers that have the VPN Client (running or not) could access the internet. Computers that have no customer VPN can access only certain sites. Commonly viewed sites would say "site found. Waiting for answer", but the answer would never come and IE 6.1 cling. When I would try ping sites, it would fail. However, some sites such as Google.com would work.
On one of the computers, on a whim of head, I installed the VPN Client but have not set up a connection. Now, this computer will connect to any website I want.
Is there a fix easier to get access to other computers on the network without installing the VPN Client on each of them?
Thank you
H. Adams
Hello
Looks like you are running in MTU problem. The reason I say it is, automatically reduces the MTU value to 1300 VPN client during the installation for the whole system. That is to say all the client computer installed VPN that have MTU from 1300.
Try to cut down the MTU of other systems that have no VPN client installed to 1300. If it's a Windows system, you can use Dr. TCP (free).

Access remote VPN, no split tunneling, internet access. Translation NAT problem
Hi all, I'm new to the forum. I have a Cisco ASA 5505 with confusing (to me) question NAT.
Unique external IP (outside interface) with several translations of NAT static object to allow the redirection of port of various internal devices. The configuration worked smoothly during the past years.
Recently, I configured a without the split tunneling VPN remote access and access to the internet and noticed yesterday that my port forwarding has stopped working.
I reviewed the new rules for the VPN NAT and found the culprit.
I've been reviewing the rules again and again, and all I can think about and interpret it, I don't know how this rule affects the port forwarding on the device or how to fix.
Here's the NAT rules, I have in place: ('inactive' rule is the culprit. Once I have turn on this rule, the port forwarding hits a wall)
NAT (inside, outside) static source any any static destination VPN_Subnet VPN_Subnet non-proxy-arp-search to itinerary
NAT (outside, outside) static source VPN_Subnet VPN_Subnet VPN_Subnet VPN_Subnet non-proxy-arp-search of route static destination
NAT (outside, outside) source VPN_Subnet dynamic interface inactive
!
network obj_any object
NAT dynamic interface (indoor, outdoor)
network of the XXX_HTTP object
NAT (inside, outside) interface static tcp www www service
Access-group outside_access_in in interface outside
Route outside 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx 1Any help would be appreciated.
Try changing the nat rule to VPN_Subnet interface of nat (outside, outside) the after-service automatic dynamic source
With respect,

No Internet connectivity with ASA 5505 VPN remote access
Hello
I configured ASA 5505 for remote access VPN to allow a remote user to connect to the Remote LAN officce. VPN works well, users can access Office Resource of LAN with sahred etc., but once they have connected to the VPN, they are unable to browse the internet?
Internet navigation stop working as soon as their customer VPN connect with ASA 5505 t, once they are disconnected from VPN, once again they can browse the internet.
Not ASA 5505 blocking browsing the internet for users of VPN? Is there anything else that I need congfure to ensure that VPN users can browse the internet?
I have to configure Split Tunnleing, NATing or routing for VPN users? or something else.
Thank you very much for you help.
Concerning
Salman
Salman
What you run into is a default behavior of the ASA in which she will not route traffic back on the same interface on which he arrived. So if the VPN traffic arrived on the external interface the ASA does not want to send back on the external interface for Internet access.
You have at least 2 options:
-You can configure split tunneling, as you mention, and this would surf the Internet to continue during the use of VPN.
-You can set an option on the ASA to allow traffic back on the same interface (this is sometimes called crossed). Use the command
permit same-security-traffic intra-interface

VPN internet connection hangs after disconnection with tunnel of private clients
I have to use a customer Cisco VPN (private tunnel) and due to the company safety Windows Remote Desktop. This stop my normal internet access and the limit to a public internet connection "unidentified". After that I closed the Office remotely Win and disconnect the Cisco client, my PC back to my normal internet connection, but it remains unavailable until I have unplug my normal connection and reconnect. Is there a setting to Win 7-32 that will force the Cisco to get totally tunnel or a framework that will automatically fully my connection internet normal House?

ACS 3.0 Windows, VPN, remote access and external databases
I'm trying to implement a VPN solution, and most are very good.
We have a VPN concentrator, which authenticates with CSACS and who, in turn, back off the coast of authentication with a Windows domain. Unknown user policy allows new users themselves create dynamically.
The VPN uses the Cisco VPN client. The hub is visible on the internet, and the bit works fine.
Bit difficult, but we are also trying to set up the access line by using a phone company for users who do not have their own internet access.
I have problems which to authenticate to the Windows domain.
If I manually create a user and add a chap password, this user can authenticate OK. If I manually add a password of chap user can authenticate.
If the user does not exist I get "user CS unknown', if I did not add a password manually, but the user is I get"Invalid password CS CHAP", so it seems that the problem is is interrupting this authentication against the field, but I don't see why.
The telephone company radius server in my network as a aaa client configuration and is almost the same configured as VPN concentrators (the difference is the Conc VPN is configured as 'RADIUS (Cisco VPN 3000)' and as 'RADIUS (IETF)' radius server)
Any thoughts?
You cannot use CHAP to authenticate a domain Windows, the way THAT CHAP requires the password must be stored is incompatible with the Windows passwords. You need to configure each connection Dial-Up Networking to dial-up users to use MSCHAP or PAP.

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:

Internet access AnyConnect SSL - U Turn
Hi team,
I'm not great when it comes to VPN and SSL on the SAA, so I'm looking for assistance please. At the moment we have anyconnect deployed for laptops. The idea is that they SSL VPN to ASA and then have access to the resources of the company as well as internet. But we want internet access through the ASA, which is the bit that has stopped working. Maybe a change in configuration or something, don't know yet. I checked the NAT and the rules, the habit, and he seems to agree. Apparently, some users are working, but some are not. I have a laptop with the client and it does not work. Config is attached.
Help with configuring and troubleshooting would be much appreciated.

It would work for a WLAN internet access?
Hi, everyone, I have a few questions about how to implement public access to Internet in our workplace that would not allow access to our local network. We have several access points 2702 and 2504 WLAN controller. Two of the four interfaces on the 2504 have intellectual property in the ranks of our LAN subnets. I assigned a VLAN for public access to the Internet, but do not know how I would implement on our infrastructure past. Instead, I was thinking about a cable connected to one of the unused interfaces on the 2504 to a port on our DMZ switch and having traffic for the public Internet, out across the demilitarized zone. If I had to do this way, but also created a scope DHCP for the public Internet, and the DHCP scope were on an interface that had an address on the local corporate network, customers would always get the address? What is the best way to do it?
A second question I have is about how the traffic between the access points and the controller is managed. When a client connects to the access point, their traffic get dug to the controller and then thrown on the LAN, or the traffic goes to the local network directly from the access point? The reason why I ask is that we have a remote office that we would like to manage the access point of the controller in the Office at home, but we do not want necessarily all their traffic going back or the office, if it was intended for office network at home, or if it is intended for the Internet. The remote desktop has its own local internet connection and is just VPN'ing to the desktop at home for internal network traffic. DHCP for clients at the remote office is managed by a DHCP server on the router on this effect. A remote desktop access point connected to the controller in the head office would be able to use the DHCP server on the router to the remote desktop? I test that out in a lab environment and I couldn't get it to work this way. Remote desktop access point is currently running in mode independent and done a good job. In the future, this site will also get on our MPLS and finally all traffic going to get dug towards the Home Office, including Internet access, so perhaps at that time, attach the remote AP to the controller would be better.
Thank you!
A second question I have is regarding to how traffic is handled between the access points and the controller. When a client connects to the access point, does their traffic get tunnelled to the controller and then dumped onto the LAN, or does the traffic go to the LAN directly from the access point?
In local mode APs switch always centralized traffic, that is to say CAPWAP tunnel established between AP & WLC. If all traffic comments terminate at WLC connected switch.
In your case, if you map the traffic comments-SSID to the physical port connects to the DMZ switch, guest SSID users end traffic to DMZ switch. You must ensure that traffic vlan is not go on any other connected WLC trunk ports.
If AP mode FlexConnect, then traffic will end at the switch where AP connected locally.

Internet access from the default remote gateway? NO SPLIT TUNNELING
I am facing a problem for a long time, I have an ASA5505 I went through a lot of config and research until I got the inside interface to be able to go to the internet; However my VPN clients are unable to go to the Internet. Now, here's the network config:
-J' have a router (which is a modem and a router and an AP) 3 in 1... This router is connected to the ISP with a coaxial cable. the Interior is 192.168.0.0/24 network.
-L'ASA is connected to rotate inside the network of its ' outside the interface.
-L' SAA within the 192.168.1.0/24 network is a configured static gateway already (which is the router)
outside the int > default gateway 192.168.0.1 (which is the internal IP address of the router). -Inside the ASA computers are able to connect to Web sites (but I can't do anything outside the network of CMD PING)!
-When a VPN cleint to connect using IPsec (without certificate) by using a Cisco VPN client software, the client can ping and do the remote desktop connection with computers on the same within the network (192.168.1.0/24) but can not pass the Internet even know that other computers on the network can go to the internet.
-One of the computers on the network (the inside network) is a DC server 2008 R2 which can go to the internet, as I mentioned above.
What I'm trying to do is have the VPN clients to be able to go to the internet with the help of which the ASA inside the NETWORK card as a default gateway (192.168.1.1), I already have the VPN configuration with the name of the group, preshared key, user name and password and without the split tunneling (which is what I want)
Thank you
Hello
The most common problem by getting ICMP to work through the ASA failed ACL or the ICMP Inspection rules.
Check your configurations of current ' policy-map ' on the SAA with the command
See the race policy-map
I assume you have the default configurations 'policy-map' on the SAA, that are attached to the global
Under ' policy-map ' configurations, you should see several 'inspect' commands. Pass under the correct configuration mode (where the current commands are found) and add the following
inspect the icmp
inspect the icmp error
Then retest the ICMP through firewall.
In regards to the VPN Internet traffic, we would need to know the level of Software ASA which you can check with the command 'show version'
You must first verify that you have this command
permit same-security-traffic intra-interface
This will allow the traffic to the VPN users access the interface ' outside ' of the ASA, get PATed and then leave again through the ' outside ' interface. Without the command above it will not work. Will never go the VPN Internet user traffic through the interface "inside" of your ASA.
Then, you will also need the dynamic configuration PAT for your VPN users, so they are translated at the same IP address that users of LAN behind the ASA. This format of configuration depends on the software level, that I mentioned above
On a SAA running 8.2 (or below) you would usually have this configuration
Global 1 interface (outside)
nat (inside) 1 0.0.0.0 0.0.0.0 (or the mentioned specifically LAN)
To activate the dynamic PAT for VPN users that you would add
NAT (outside) 1
On one ASA 8.3 running (and above) you can configure the dynamic PAT for users of VPN in the following way
network of the VPN-PAT object
subnet
dynamic NAT interface (outdoors, outdoor)
It should be. Of course, you could have a configuration that may replace it, but I doubt it.
Hope this helps
