how to setup a both ends of an IPSEC VPN tunnel using a software client such as shrewsoft vpn and an 800 series router?
I've tried following the instructions on cisco's site, but I don't really understand which interface I should use? Dialer, VLAN1 or UnNumbered to a Loopback?
I'm OK with most basic features of the router, but never had any luck with VPNs?
I have configured a lab for RA VPNs with a ASA5510 software version 8.2 and VPN Client 5 using digital certificates with Microsoft CA on a Windows 2003 server. I did the configuration based on this document from Cisco website: URL
Now the vpn works just fine, but now I need to configure different tunnel-groups so I can provide different services to different users. The problem I have now is that I don't know how to configure it so the certificate matches the tunnel-group name. If i do a debug crypto isakmp on ASA I get this error messages:
%ASA-7-713906: IP = 165.98.139.12, Trying to find group via OU...%ASA-3-713020: IP = 165.98.139.12, No Group found by matching OU(s) from ID payload: Unknown%ASA-7-713906: IP = 165.98.139.12, Trying to find group via IKE ID...%ASA-3-713020: IP = 165.98.139.12, No Group found by matching OU(s) from ID payload: Unknown%ASA-7-713906: IP = 165.98.139.12, Trying to find group via IP ADDR...%ASA-7-713906: IP = 165.98.139.12, Trying to find group via default group...%ASA-7-713906: IP = 165.98.139.12, Connection landed on tunnel_group DefaultRAGroup
So basically when using certificates I always connect the RA VPN only with the default group DefaultRAGroup. Do I need to use a different web enrollment template for certificate request instead of the user template??? How can I define the OU on the User certificate so it matches the tunnel-group???
I have succesfully config an IPSec VPN Tunnel by using a Router Scientific Atlanta Cisco 2320 and a RVS4000 4-Port Gigabit Security Router with VPN.On the site of Router Scientific Atlanta Cisco 2320 this is some info: [code] On the site of RVS4000 4-Port Gigabit Security Router with VPN this is some info: [code] Remember that you can not be on the same range of IP, I mean, you can not have 192.168.0.X if the remote network is on 192.168.0.X, you have to change some of the Routers.I show the configuration on Router Scientific Atlanta Cisco 2320: I show the configuration on RVS4000 4-Port Gigabit Security Router with VPN:If all is correctly configured, you should see on Router Scientific Atlanta Cisco 2320 the Status Connected:

we have a cisco ASA 5505 and are trying to get the following working:
vpn client (ip 192.168.75.5) - connected to Cisco ASA 5505
the client gets a specific route for an internet address (79.143.218.35 255.255.255.255 192.168.75.1 192.168.75.5 100) when i try to access the url from the client i get a syn sent with netstat when i try the packet tracer from the ASA i see the following:
<Phase>

Is there any way to setup an IPSEC tunnel to be able to go from my subnet, 192.168.75.x and be able to reach anything on the other side of the tunnel, 192.168.X.X?

If i run a ping from outside the network, i can ping the IPv6 address of the server end, however, i cannot ping the E4200's end of the tunnel. is there a specific option that needs to be set? i have allowed ping so that my IPv4 address is pingable, am i missing something for IPv6?
View 7 Replies View RelatedWe are setting up an old office building as an offsite data center. The network cosists on a PIX 501 firewall and a 2811 router. I am attempting to setup a GRE tunnel over IPsec back to the main office. The main office consists of a PIX515, a 2821 router, and a 2921 router.
There is also an ASA5510 in our main office that is used as our primary connection for all of our external services and as a GRE endpoint for our other offices. The PIX515 is used to connect our main office clients to the internet and we would like traffic between it and our offsite data center to go across it as well. The default route is to use the ASA. We used policy based routing on the 2821 and 2921 routers to direct the appropriate traffic to the PIX515. Right now I am not able to get the tunnel setup. It appears that the offsite datacenter is sending packets but is not receiving any when I issue the “show crypto ipsec sa” commands on both firewalls. I will show the output of that command below.

i'm using an rv220W and i whant to know if is it possible to assign vpn traffic to a vlan when i setup an ipsec tunnel?
example:
Im using different vlans on my rv220W.
Vlan 10: engineers (ex: 192.168.1.0/27) no intervlan routing
Vlan20: sales (ex: 10.0.123.0/24) no intervlan routing
This is what i need: - An engineer is on the road and when he makes a ipsec vpn connection => assignd to the vlan "engineers" so he can access the server/pc's in that vlan.and when someone from the sales group starts a vpn connection he needs to be in the vlan "sales" so he can access his pc/data,...
We currently have a client that uses the IPSec VPN Client to remote in to their PIX 501. When they connect, it secures communication and immediately connects/minimizes and the tunnel-group name/password is sufficient so no prompt for a username/password from a local/radius database.
When setting this up on a newly purchased ASA, a username/password is prompted every time they try to connect. Is there a way to eliminate this feature or a command in the tunnel-group or group policy so that a username/password is not required after the connection profile establishes the VPN? It is ASA 8.4.
How can I set up a Cisco 831 router (branch location) so that it will accept inbound VPN Client connections and initiate a site-to-site IPSec tunnel to our hub location that uses a VPN 3005 Concentrator? I could get the tunnel to work by configuring it in a dynamic crypto map but interesting traffic on the Cisco 831 side would not bring the tunnel up.

We have a Cisco 2820 that serves as a hub and our spokes are Cisco 871s. Its been working for a while and for some reason last week. Http and https traffic over the tunnel is having connection issues. I can Remote desktop or PCanywhere into the remote PCs. From that PC I can ping internal IP address or IP of the webmail server or internal webserver with no issue. But if I access it over the browser it times out or it will work and stop working again. Basically ica, icmp, pcanythere, rdp traffic works over the tunnel but not http or https.

i am curently troubleshooting a ipsec l2l VPN between
1. ASA 7.2(4) to SSG-140
2. Cisco 871W to SSG-140
In both scenario's the tunnel is nicely established, and traffic goes into the tunnel, but nothing comes out. All encap's, but no decap's
It seems like a routing issue, but we can not find anything on both sites.
So maybe i m running into a (known) issue between cisco VPN equipment and the SSG-140?
Could it be a proxy-id issue? Cause they configure stuff like 10.1.1.0/24 and i configure 10.1.1.0 0.0.0.255
I'm attempting to configure a tunnel on a PIX-501 version 6.3. It's an old device that's due to be replaced soon, but unfortunately we need a tunnel now... I have been using this document as a reference (6211): URL ,The remote end is a sonicwall.
The problem seems to be that the pix never sees the interesting traffic for the tunnel, and never tries to initiate a connection. I have enabled crypto ipsec and crypto isakmp debugs, but no data is ever displayed, even when attempting to access a device on the remote side of the tunnel! Someone had tried to set up this device with some tunnels in the past, but was never successful, so I'm thinking there might be remaining commands in the running-config causing problems.
configuring some static NAT entries on a remote site 887 router which also has a IPSec tunnel configured back to our main office.
I have been asked to configure some mobile phone "boost" boxes, which will take a mobile phone and send the traffic over the Internet - this is required because of the poor signal at the branch. These boxes connect via Ethernet to the local network and need a direct connection to the Internet and also certain UDP and TCP ports opening up.
There is only one local subnet on site and the ACL for the crypto map dictates that all traffic from this network to our head office go over the tunnel. What I wanted to do was create another vlan, give this a different subnet. Assign these mobile boost boxes DHCP reservations (there is no interface to them so they cannot be configured) and then allow them to break out to the Internet locally rather than send the traffic back to our head office and have to open up ports on our main ASA firewall.
[URL]
So I went ahead and created a separate vlan and DHCP reservation and then also followed the guidelines outlined above about using a route-map to stop the traffic being sent down the tunnel and then configured static NAT statements for each of the four ports these boost boxes need to work. I configure the ip nat inside/outside on the relevant ports (vlan 3 for inside, dialer 1 for outside) The configuration can be seen below for the NAT part;
! Denies vpn interesting traffic but permits all otherip access-list extended NAT-Trafficdeny ip 172.19.191.0 0.0.0.255 172.16.0.0 0.3.255.255deny ip 172.19.191.0 0.0.0.255 10.0.0.0 0.255.255.255deny ip 172.19.191.0 0.0.0.255 192.168.128.0

I have been struggling for a few days with getting site-to-site traffic working across a L2L IPSec tunnel. At this point, I have the tunnel up, and I see packets being decrypted on the correct IPSec SA's when I ping from a local network computer on the ASA side to a local network computer on the router side. I cannot ping from one side to the other, but those packets are getting through. We have another L2L tunnel that is from that ASA to another remote site's ASA, and that is functional. I have mirrored the configuration for ACLs, etc. from that site, so I believe that the issue is with the packets getting incorrectly translated by the NAT/NONAT statements/ACLs on the router side.
View 8 Replies View Relatedsince a few days I'm trying to solve a problem. I've successfully established an IPSec tunnel between two local LANs. In the main office I'm working with a ASA5510 CLI 8.4 and a static public IP address. The branches are using different Cisco 8xx routers and dynamic public IP address. The following picture shows the current configuration:As I mentioned an IPSec Tunnel between the main office "Intern"-LAN 192.168.1.0/24 and an outside LAN 10.10.0.0/24 is successfully established. Now there is a new intern "Admin"-LAN 192.168.2.0/24 at the main office. The users from the outside LAN 10.10.0.0/24 need the possibility to reach this new intern "Admin"-LAN.Can I simply route the traffic from 10.10.0.0/24 to 192.168.2.0/24 via the existing IPSec-Tunnel? Or need I a new IPSec tunnel between the outside 10.10.0.0/24 LAN and the new "Admin"-LAN 192.168.2.0/24?

I have a site to site IPSec tunnel setup and operational but periodically the remote site goes down, because of a somewhat reliable internet connection. The only way to get the tunnel to re-establish is to go to the remote site and simply issue a ping from a workstation on the remote network. We were having this same issue with a Cisco PIX 506E but decided to upgrade the hardware and see if that resolve the issue. It ran for well over a year and our assumtions was that the issue was resolved. I was looking in the direction of the security-association lifetime but if we power cycle the unit, I would expect that it would kill the SA but even after power cycling, the VPN does not come up automatically.

I've created an IPSEC VPN site-to-site from a SR520 (remote office) to a Nortel Contivity(home office)...all works really well on the VPN front as I can communicate effectively over the tunnel. However, this setup will be deployed at a few smaller sites and I'd like to setup a split tunnel so that Internet bound traffic goes straight to the Internet while traffic bound for our home office goes over the IPSEC Tunnel.

All worked well however there is one site running really strange. The tunnel between 1900 is up for a while and down. Reboot router seems to be the only fix. But tunnel to ASA does not seem to be down at all.
The issue happened again today, we rebooted the router on site but tunnel still not up. DEBUG shows: deleting SA reason "Death by retransmission P1 "

To me it seems like the IDE packet sent but never got reply and timed out. I did also check on the other end, the HQ. All other tunnels are still running fine on that router, just this remote site. Plus I got the similiar output when debugging on HQ router.
One thing do notice though, there was no match on both router for the ACL to match/permit ESP traffic... I asked on-site staff to reboot the modem used in remote site.

I'm having some trouble configuring 2 cisco routers (877) with ipsec vpn tunnel.The 2 of them are linked to the internet with dynamic adsl's - their ip-addresses changes all the time.when the configuration is based on ip addresses it's working ok, but when I'm trying to use host name with the DDNS feature, it's not coming up, I get a lot of errors...
I've searched google and various posts regarding that issue.It's seems like it's possible to do a dynamic-ip to dynamic-ip ipsec tunnel, but I found zero manuals and configuration.I've added the template that I'm using to configure the tunnel with ip addresses.
