Access remote vpn fails
Hello
Im trying to figure out why vpn for remote access is at our company office fails. The scenario: we currently have a work situation. The way this works is that users connect to the public ip address of the DSL router and nat vpn traffic to an internal router. This router then forwards the traffic to the vpn server.
vpn client remote <=>{{internet}} <=>cpe <=>adsl router <=>vpn server
Now, Im implementation of a 2nd internet line with more or less the same configuration, but instead of an adsl cpe, we use a cisco router. When users need to connect even with the only difference being a different public ip address
client remote vpn <=>{{internet}} <=>cisco <=>router <=>router, vpn server
So, the only change in the prepective of cisco vpn clients is the host. However when testing, it didn't work. The vpn client times out. With something like 'the vpn peer did not' do not remember the exact error by heart. Now logic tells me that because he now works in the part between the internal router and the vpn gateway is ok. My guess is it's because of the cisco access list. I had my own list of access, but for some reason, I decided to use firewall SDM Wizard configuration and it generated this access list.
Expand the IP 100 access list
10 permit tcp any host 90.90.150.82 eq 4500
20 permit tcp any host 90.90.150.82 eq 500

40 permit tcp any host 90.90.150.82 eq 50
50 permit tcp any host 90.90.150.82 eq 3101
60 permit tcp any host 90.90.150.82 eq 993

110 permit icmp any host 90.90.150.82 time exceeded (54 matches)
120 permit icmp any inaccessible 90.90.150.82 host (1051 matches)
130 deny ip 10.0.0.0 0.255.255.255 (726 matches)
140 deny ip 172.16.0.0 0.15.255.255 all
150 deny ip 192.168.0.0 0.0.255.255 everything
160 deny ip 127.0.0.0 0.255.255.255 everything
170 deny ip 255.255.255.255 host everything
180 deny host ip 0.0.0.0 everything
190 deny ip any any newspaper (5163 matches) Extended 100 IP access list
Given that the natting to the smtp protocol works, I think that the natting is ok. I ping the server vpn, so routing also seems to be ok. Vpn users receive a vpn ip address pool 192.168.x.x. is it possible that the 150 rule that prevents them to connect? I can't test, because it's a living environment and I'll have to plan a window. Im just trying to figure out what is wrong, so I can fix it for a window. Someone at - it ideas?
No, you don't need AH if your VPN policy does not include AH.

Please note that the configuration is incomplete, I added that relevant changes, you should bring to the allow clients of RA through the LAN-to-LAN tunnel, of course, the LAN-to-LAN settings should match to the other side of the tunnel that is mirror of ACL, NAT and so on.

1920 router access remote vpn LDAP living
Hello
What is required for a router in 1920 use AnyConnect and/or also integrate with AD LDAP?
Currently, this router supports legacy clients and has these licenses:
Technology for the Module package license information: "c1900".
-----------------------------------------------------------------
Technology-technology-package technology
Course Type next reboot
------------------------------------------------------------------
IPBase ipbasek9 ipbasek9 Permanent
Security securityk9 Permanent securityk9
given none none noneThe vpn to access remote client inherited integrate with AD LDAP?
Thank you.
As long as you are on IOS 15.3.3M3 or better, you have all the licenses you need for 3.1 AnyConnect run on your 1921.
The guide to directly connect your router to LDAP can be found here:
Personally, I would avoid directly interfacing with LDAP, because it can be a complex arrangement. While it can be done, it's easier to have your router to connect to the NPS Microsoft via RADIUS server for your authentication.

a public access remote vpn from an inside interface asa 5505
I'm trying to see if it is possible to accomplish what I am trying. I have an ASA 5505 with the following configuration.
1. There is an external connection, connected to the ISP. Let's say that it is 10.1.1.1/24 for ease. There is a remote VPN configuration as the access of people through this interface.
2. There's the inside network, which is the normal LAN. It's cable system in the office. to say that it is 172.20.0.1/24.
3. There is a wireless network on a VLAN separate called WLAN. It has an IP of 192.168.1.1/24. There is an ACL allowing traffic to that VLAN to the public internet.
Essentially, I would like users to be able to use the same VPN settings they use when connecting from outside of the Office when you are connected to WIFI.
Also, I would like that they can access public IP addresses that I have NAT would be to internal servers. In this way, they can use IP addresses when they use on the public internet.
Is this possible?
Hello
Well that's not going to be possible, the only thing you can really do is to activate the crypto map on the WLAN facing interface, by design, you cannot not access VPN, ping or manage the device on an interface which is not directly connected to you.
I hope this helps.

Access remote VPN question - hairpin
Hello, I did a search before posting this question but I have not found anything specific to my situation.
We have our ASA5520 configured in our main office to allow remote access Cisco VPN client users to access our network. We have a (network 192.168.1.0/24) remote desktop we have a configured on the same ASA5520 VPN IPSec tunnel that allows the use of internal users (in the main office) to access resources on the network remote (192.168.1.0) and vice versa. The problem is that when users connect to the remote VPN access, they are not able to access the resources of the remote office network. We created the nat0 ACL and labour, and split tunnel routing is implemented for users VPN remote network access (if I make a copy of the route on my laptop after connecting to the VPN, I see the road to 192.168.0.0/24 in my routing table). Routing everything is in place to do this, since the IPSec VPN tunnel is up and working. My suspicion is that the question has something to do with the consolidation of these VPN clients.
What else needs to be configured to work? Thank you.
Hi Scott,.
I have a client with a PIX 515E which allows connections to remote VPN and VPN LAN2LAN multiple connections.
We had this problem too... so what I made in my pix was:
TEST (config) # same-security-traffic intra-interface permits (its off by default)
If you use ASDM go to:
Configuration > Interfaces >
at the bottom of this page, there is an option that says: 'enable traffic between two or more host computers connected to the same interface '.
Check and it should work... I hope
I await your comments...
Kind regards.

Cannot access remote VPN site-to-site VPN
Internal network: 192.168.0.0/16
The remote VPN Clients: 192.168.0.100 - 192.168.0.254
Remote (L2L) network: 10.10.10.0/26
Remote VPN Clients are able to access the internal network without problem, but are unable to access the remote 10.10.10.0. Is it possible to debug this? "packet - trace" show no problem...
Hi Ben,
Please create a no. - nat on the external interface, because your customers to vpn-remote and remote-L2L tunnels are located on outside interface (i.e. from the outside). You should treat your outside network identical to your inside network, as you would create a no. - nat for your inside networks.
The ACL you create for the no - nat outside must be in both directions as below.
permit access ip 192.168.0.0 scope list outside_nat0 255.255.255.0 10.10.10.0 255.255.255.192
outside_nat0 to access extended list ip 10.10.10.0 allow 255.255.255.192 192.168.0.0 255.255.255.0
NAT (outside) 0-list of access outside_nat0
permit same-security-traffic intra-interface
Pls let me know, if this is useful.
Thank you

Divide access remote vpn tunnel ASA 5520
Hello
I'm setting up a vpn for remote access with split tunnel, but I use an acl extended to match a host and http to destination port, but does not work.
Scenario of
Distance access(10.0.0.122/24)--internet---Cisco ASA(inside:192.168.10.1/24)---ip = 192.168.10.6 - C6509 - 10.0.0.254/24---hote = 10.0.0.31/24
The plot is when I activate the IP service connection or flow ICMP worked. Does anyone have an idea what is the problem? Thank you
Concerning
Split tunneling does not take into account the port information you specify in the ACL, he doesn't care the ip address/network you defined.
If you want to restrict access to ports and IP, you must define your split tunneling with only ip addresses and using a vpn-filter acl in group policy to restrict following the specific ports that you want:
split_acl ip access list allow
access-list allowed filter_acl ip eq
attributes of group-pol
Split-tunnel-pol tunnelspecified
value of Split-tunnel-net split_acl
VPN-filter value filter_acl

Cisco IOS - access remote VPN - route unwanted problem
Hello
I recently ran into a problematic scenario: I am trying to connect to a remote LAN (using a Cisco VPN client on my windows xp machine) my office LAN and access a server there. The problem is that I need a remote local network access at the same time.
Remote LAN: 172.16.0.0/16
LAN office: 172.16.45.0/24
Topology:
(ME: 172.16.10.138/25) - (several subnets form 172.16.0.0/16) - (Internet cloud) - (VPN-Gateway) - (172.16.45.0/24) - (TARGET: 172.16.45.100)
To provide access, I configured a VPN to access simple distance on a 1700 series router. It's the relevant part:
(...)
crypto ISAKMP client config group group-remote access
my-key group
VPN-address-pool
ACL 100
IP local pool pool of addresses-vpn - 172.16.55.1 172.16.55.30
access-list 100 permit ip 172.16.45.100 host 172.16.55.0 0.0.0.31
(...)
The configuration works fine, I can access the 172.16.45.100 server every time I need to. However, the problem is that when the VPN connection is connected, Windows wants to somehow rout the packets intended for 172.16.0.0/16 through the VPN tunnel. This is apparently due to a static route that added by the Cisco VPN Client and all other specific VPN routes.
I suspect that the culprit is the IP LOCAL POOL, since when the VPN is connected, debugging of Client VPN log shows something like "adapter connected, address 172.16.55.1/16. Focus on the part "/ 16". I checked the VPN status page and the only road indicated there was "172.16.45.100 255.255.255.255" under remote routes. Local routes was empty.
Is this a known problem I missed the obvious solution for? Is there no workaround apart from the pool local vpn penetrating high-end 10.x.x.x or 192.168.x.x? Thank you in advance for advice or tips!
Hello
The best way is to avoid any overlap between the local network and VPN pool.
Try 172.17.0.0/16, is also private IP address space:

Hi all
IM, configuration of a vpn for remote access with ldap, for what I see in some examples, I need to create a user/pass.
In my case, I already configured the aaa for the ldap Protocol Server. I also have the Group tunnl with the authentication server.
I need to create a user/pass?
Thank you.
Hello
I see what you mean!
It is not necessary for the integration of LDAP.
You don't have authentication LDAP not the LOCAL database, so no need for this.

Hello
I have previously edited the my initial response was in fact not necessary since you were actually using full Tunnel
EDIT: Actually just noticed the the VPN client isnt using Split Tunnel. Its Full Tunnel at the moment since it doesnt have the "split-tunnel-policy tunnelspecified"
So you don't really have any of those.
Please mark the question answers and/or assess response
Ask more if necessary

Please help me!
Concerning
Can you upgrade to a new vpn client or try to disable the firewall in XP sp 2? I think the problem is that this old clients are not supported on xp sp2 or will have problems with the firewall in SP2. Try to run a higher customer or 4.0 x.

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,
Safwan

AnyConnectVPN users cannot access remote vpn site-to-site
Hello-
We have two 5510 s ASA one in 8.4 (4) and the other to 8.2 (5) in a site to site VPN configuration. All internal traffic is working smoothly.
A: site/subnet 192.160.0.0 - local (8.4 (4)) Site/subnet b: 192.260.0.0 - distance (8.2 (5)) VPN users: 192.160.40.0 - assigned by ASA
When you VPN into the network, all the hits of traffic A Site and everything on the subnet A is accessible.
However, the site B is totally inaccessible to users of VPN. All computers on subnet B, the firewall itself, etc. is not reachable by ping or otherwise.
There are also some NAT rules weird that I'm not happy with that were created after that I upgraded the Site to ASA to 8.4
A resident of the site: external 192.160.x.x: 55.55.555.201(main)/202(mail)
Site B (in addition to site to site) is external 192.260.x.x: 66.66.666.54 (all)
I've pretty much just the basic rules of the NAT for VPN, Email, Internet and site to site.
What I need to add for the VPN access to the network from site to site?
Here is my config NAT:
NAT (inside, outside) static source DOMAIN_LOCAL DOMAIN_LOCAL VPN_Network VPN_Network non-proxy-arp-search of route static destination
NAT (inside, outside) static source DOMAIN_LOCAL DOMAIN_LOCAL DOMAIN_REMOTE DOMAIN_REMOTE non-proxy-arp-search of route static destination
!
network of the DMZ_Network object
dynamic NAT interface (DMZ, outside)
network of the DOMAIN_LOCAL object
NAT dynamic interface (indoor, outdoor)
network of the EXCHANGE_Exchange object
NAT static Outside_Mail (any, any)
network of the DOMAINCTRL_DHCP object
NAT (inside, outside) interface static tcp ftp ftp service
Thank you very much in advance and I hope that I've been pretty thorough.
Let me know if you need anything that anyone else. Thank you!!
Theo,
You don't need the NAT rules outside (depending on your configuration).
Basically, you need to add the pool VPN L2L traffic and network remote to the ACL of split tunneling (if configured), also the "permit same-security-traffic intra-interface".
Please let me know.
Thank you.

Access remote vpn for the cisco1841
Hi all
Can I have an example configuration of a vpn for remote access to work for cisco router 1800 series?
My cisco 1800 series router already a site to site vpn, so can I still set up a vpn for remote access using the existing IKE policy?
Is it true that cisco router do support 1 IKE policy? Pls advise. Thks in advance.
what you have is correct
the line of authentication that you mentioned on is to suggest that we use the local user database authentication
If you have an external aaa server as Ganymede + or radius, you can specify that, instead of local, local, is a key word to suggest local authentication
your local database would be so user name passwords what ever you store on the router as
username cisco password cisco
hope this helps
If this answers your question please note this as responded to the benefit of users in the community

Split DNS on ASA 5510 access remote vpn works not
I connect successfully to the tunnel and can ping hosts remotely by IP but am unable to browse the internet from the VPN client. Also, the resolution of host name on the remote end does not work... can only connect through the IP address. Ideas? Thanks again!
Your group policy will SUFFER a good split tunneling and divide the dns settings. But I think that you are awarded the DfltGrpPolicy rather than your group policy will SUFFER because group policy is not set in your group of tunnel, nor be transmitted from authentication.
Make a vpn-sessiondb distance 'show' to confirm what group policy is assigned to fix it, assign your group policy will BE to your group of tunnel as follows:
global-tunnel-group attributes
Will BE by default-group-policy
