Remote vpn routing issue
Hi, please find the attachment.
I want remote access client vpn server that connect you to my ASA 5510 outside interface.
Is this possible via the static route set or something else?
Thank you very much!!!
Hello
There is not enough information to give a good answer. This should be possible, but your level ASA software firewall and VPN Client configurations factor in this also.
If you have a customer VPN Split Tunnel configuration, then you must add a rule to the existing ACL and say the IP address of the server. If you use Client VPN full Tunnel while you don't have to worry about the same thing only with Split Tunnel.
Then you will probably need the configuration "permit same-security-traffic intra-interface" so that traffic can enter the 'outside' and leave 'outside' to the server. It won't work without the mentioned order.
You will also need a PAT Dynamics example
If you use a software 8.2 or below and have this dynamic PAT defect for LAN users
Global 1 interface (outside)
NAT (1 x.x.x.x y.y.y.y inside)
Then for the Pool of Client VPN you can add this
NAT (outside) 1 20.20.20.0 255.255.255.0
More often, this should be sufficient to allow the traffic to arrive on the VPN Client user ASA and out of 'outside' interface and head to the server.
Hope this helps

There is a way to disable the Ping process and continue with the VPN connection?
QuickVPN try ping on the router via the VPN tunnel to check the connection. It should work without worrying about whether your ISP filters ICMP messages or not. The tunnel is encrypted your ISP won't know what you're doing.
Please post the corresponding on the RV042 VPN log. That is expected to see how far you get.
You have a firewall running on the computer? I think that some firewalls have difficulty with the traffic of ESP.
What is the router that is connected to the computer? How is it that is configured?

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:

Please rate if this helped.

I am trying to configure client vpn software ver 5.0 for remote to connect to the local network behind a 1801 users.
I can get the client saying its connected but traffic is not circulate outside in:
When I try to ping an address 192.168.2.x behind the 1801 I get a response from the public ip address but then when I try to ping to another address I have no answer.
I guess the question is associated with NAT.

Thank you in advance.
Hi Eric,.
Unfortunately not, this is controlled by the VPN server.
You can try changing the routing on your machine by using static routes, but it is not supported, because it is considered a security risk.
I would recommend you to communicate with the remote administrator and explain that you must "split tunneling" instead of "tunnelall".
Thank you.

RVS4000 / WRVS4400 VPN routing issue.
I would like to simplify my installation a bit, but unfortunately I do not know how to do this.
I have a triangle of CSB RVS, 2 RVS4000, 1 WRVS4400 devices
each router has a VPN gateway to gateway with 2 others, to any one of the 3 sites, you can access resources on the other 2.
It also works well, if for some reason, one of the legs of the VPN breaks down, it passes through the other router. at least it seems to work that way when it is tested.
Now enter my problem. I have 2 laptops that go around, Mine and at the office. If any of these are off site and connect to a router via the QuickVPN client. they can see the resources on the router, to which they connect.
How would I be able to connect to the Router 1 and be able to access resources on other VPN routers ' ed?
It is not so much a problem on the router because it is on the QuickVPN. When you go to an IP address that is not on the local network from the router, the QuickVPN does not and it that the request is sent to the internet.
The only way to access the other site and resources would be to unplug the first router and connect to each other.

Hello
A quick test, try this.
-Turn on nat - t (if its disable)
Command: crypto isakmp nat-traversal 20
see if it helps.
If not,
-Run a continuous ping from the client to the ASA inside the interface, make sure that you run the command 'management-access to inside' before you start with the ping.
-Time our RESPONSE ICMP or inside the interface... ?
If time-out, then
-Check the number of decrypts using the command "show crypto ipsec his"
If ICMP response to inside interface is received by the VPN client.
-Ping to an internal host behind the ASA.
-"Show crypto ipsec his"
IF you have received responses if first test then here you should see decrypts number increases.
-Apply the catches on the inside of the interface
You can consult the document below
http://www.Cisco.com/en/us/products/ps6120/products_tech_note09186a0080a9edd6.shtml
-If you see the package source as VPN client interface to reach the inside interface for the destination of the host behind the ASA, then its a problem with your routing internal.
In case you have an L3 device connected to the ASA inside the interface, make sure that you have a route for GW subnet 192.168.1.x as ASA inside the interface i.e. 172.16.1.1 score
If his L2 or a dumb device, then as a quic test, make the following statement of the road using the command-line in windows on the host computer behind the asa participant in this test.
route add 192.168.1.0 mask 255.255.255.0 172.16.1.1
Please let me know if it helps.

!Hello brother Mohammed.
"my asa5510 to work easy as Server & client vpn at the same time.?
Yes, it can work as a client and a server at the same time.
I have never seen anyone do it but many years of my understanding, I have no reason to think why it may be because the two configurations (client/server) are independent of each other.
Your ASA function as server uses the "DefaultL2LGroup" or it uses standard group policy and tunnel-group are mapped to the remote clients ASA?
Thank you

Routing of a VPN from Site to site to remote VPN users
Hello
We have a site and remote vpn site configured in the same interface in ASA 5520 (software version 8.3). When the remote vpn users try to connect to the computers located at the far end of the site to site VPN, their request has failed. I tried No.-Nat between remote vpn IP private to the private IP address of remote site, also said the same split tunneling. I can't find even the tracert, ping has also expired.
Is there any solution to make this live thing.
Shankar.
There are a few things that need to be added to make it work:
(1) on the SAA where remote vpn users connect to, you must add "permit same-security-traffic intra-interface"
(2) you mention that you have added the LAN of remote site-to-site in the list of split tunnel, so that's good.
(3) on the SAA ending the vpn for remote access, you must also add the following text:
-Crypto ACL for the site to site VPN must include the following:
permit ip access list
(4) on the ASA site to remote site, you must add:
-Crypto ACL for the site to site VPN must include the following:
permit ip access list
-No - Nat: ip access list allow

Connectivity to the remote VPN site adjacent networks
Star topology with Corporate office which acts as hub (192.168.1.x) and remote sites connected by relay frames, except for another network (172.16.x.x) in the building served by 3560 switch company.
On my remote site vpn (10.0.1.x) I can ping network 172.16.x.x, but not the 192.168.1.x network. What I'm trying to do is to allow the network traffic remote 10.0.1.x (which connects directly via the VPN network 172.16.x.x) to reach the network 192.168.1.x and vice versa.
I'm sure its a combination of NAT/routing issue I forget.
I'm new to PIX / ASA in general and it's the first vpn L2L I install. If someone can point me in the right direction, I would appreciate it.
Thank you.
It looks like this?
10.0.1.x->-> Corp. ASA L2L tunnel - >->-> 192.168.1.x 3560 172.16.x.x
and that you can currently communicate via the tunnel between 10.0 and 172.16? In order to communicate between 10.0 and 192.168.1, you will need to define this interesting traffic and add it to your crypto and nat exemption acl.
Corp site
extended access-list allow ip 192.168.1.0 255.255.255.0 10.0.1.0 255.255.255.0

Remote VPN client and Telnet to ASA
Hi guys
I have an ASA connected to the Cisco 2821 router firewall.
I have the router ADSL and lease line connected.
All my traffic for web ports etc. of ADSL ftp and smtp pop3, telnet etc is going to rental online.
My questions as follows:
I am unable to telnet to ASA outside Interface although its configuered.
Unable to connect my remote VPN Client, there is no package debug crypto isakmp, I know that I have a nat that is my before router device my asa, I owe not nat port 4500 and esp more there, but how his confusion.
I'm ataching configuration.
Concerning
It looks like a config issue. Possibly need debug output "debug crypto isa 127".
You may need remove the command «LOCAL authority-server-group»
NAT-traversal is enabled by default on the ASA 8.x version. So you don't have to worry about NAT device in the middle.

Here's the situation
I am slowly migrating from a Cisco VPN 3030 to a Cisco ASA5540 hub
My L2L tunnels come along fine, but I'm running issues with attachment for remote VPN Clients.
I implemented the AAA and it works correctly, as well as the profile. (we use IPSec)
My issues are with the IP Pool address. We use a different set of the IP as the hub.
I have implemented routing on the next hop within the ASA as the home of the ip address pool of.
But I don't get any through put.
Can I join the ASA with a Client remote check the Radius Server and all authentication through. But I can't access anything whatsoever.
All lanes of route for the IP address pool from within the network to the ASA.
Is there something else I need to put in place also just assign the IP address Pool?
any suggestions would be helpful
Thank you
The problem isn't necessarily routing. Check the following things:
1. have you for the pool VPN nat exemption (you need)... If this isn't the case you will see on any group of translation found syslog messages and traffic will be dropped. Assume that your VPN pool is 172.16.4.0 255.255.255.255. You add:
sheep ip access-list allow any 172.16.4.0 255.255.255.0
NAT (inside) 0 access-list sheep
2. do you have an access-group applied to the interface? Make a ' group-access show run. If you have applied, make sure that the access list permits traffic at the pool of the VPN client
3. If it is IPSec and the customer or the SAA is behind a NAT, you must have the following:
ISAKMP nat-traversal

WRVS4400N VPN Passthrough issues
I had a WRVS4400N router for 8-9 months. When it is connected to a remote VPN, the PC will go down intermittently to connect to the remote VPN server. Anything running on the connection, such as distance or vSphere client or network file browsing, office will be temporarily unusable, then the connection is re-established. Usually one drop lasts several seconds and varies in frequency.
A few notes:
-I can reproduce the problem with more than one PC.
-Both wired and wireless connections are affected.
-If I use an old Linksys WRT router or connect directly to the internet modem, I don't see the problem.
-J' have tried disabling UPnP, firewall and IPS without success.
I tried using wireshark, but can't identify something specific. The traffic seems to just stop for 5-10 seconds before resuming.
Any suggestions/help would be appreciated.
Mr Champion,
Have you tried just the quickvpn client and the view if your always get disconnected?
If it is stable and pull-out decision still does not work, maybe try to download a fresh firmware of cisco.com, then reflash the router with firmware then reset factory of the router and manually reconfigure your settings and see if your seeing the same issue.
I would like to know how it works.

I have a site2site between PIX506 and 877 router VPN. Site A has PIX506 and Site B router a in 877. I configured site2site VPN and it worked fine. I also configured remote VPN on PIX 506 so that the remote user can access A site. But when I configure remote VPN on PIX506 site2site VPN works and both sides can ping each other. But site B users cannot access any resource network or application of the SiteA while site A can access resources of site B. After removing remote VPN site configuration B can access the resources of the Site I joined the configuration of the two sites. Someone help me please site2site and remote VPN work at the same time.
Please forgive me for not reading every line.
an add-on quick about the pix configuration:
change "isakmp key * address 213.181.169.8 netmask 255.255.255.255" at "isakmp key * address 213.181.169.8 netmask 255.255.255.255 No.-xauth No. config-mode.
