VPN IPSEC RV220w problem
Hello, I hope someone can help with my problem.
I have a RV220w in the office, I set it for ipsec vpn connections. Behind the router, there is a NAS for file storage.
My setup as follows:
RV220w 192.168.1.1 with dyndns, configured for ipsec vpn with default Client strategies.
Remote location (my laptop) local IP: 192.168.3.2
Remote site VPN IP (given by ShrewVPN): 192.168.30.5
I managed to connect to the router at home with ShrewVPN and I can ping each client connected to RV220w.
The problem is that I can't connect to the web interface of the router or the NAS web interface or any other web page intranet (the browser gives no error, but continues to load without displaying the web page). Even if I can access the web pages of my laptop.
In addition, in windows Explorer when I log into the NAS, although I can go through the files, I can't copy the files from my laptop on the NAS and vice versa, I still get timeout error (I checked the permissions on the NAS and also I managed to copy a txt file small 1 KB) (, but no luck with large files).
I also tried with QuickVPN client, but I got the same results.
When I connect with pptp windows everything works like a charm.
My laptop has windows 7 64 bit.
If you need other configuration details, please advice.
Thank you
Hi Spyros, one of the differences between IPsec and PPTP is that IPsec requires the client that connects to use another LAN IP address, when you connect. Unlike PPTP, it is assigned by the router.
Another difference is that the requirement of bandwidth is much higher for IPsec connections.
I don't think it's a problem of IP subnet as you are able view readers to all least, then it means that the unit can accept connections from different subnets. But it is possible, it may be a problem of download speed. QVPN needs Mbit upload environ.5 to have an activity and a reliable and quality connection.
Another problem may be a matter of downtime with IPsec encryption. The RV220W has a non routable WAN address. This suggests to me that you have another router upstream. Time to answer through the IPsec tunnel can be volatile because of the translation through multiple jumps.

Hello
I have a headquarters and a remote site and I want to get a VPN site-to site between the two. I have the following Setup on each router. 'Show encryption session' says that the VPN is in the IDLE-UP condition (and my somewhat limited understanding of virtual private networks, this means that the phase 1 of IKE is complete and waiting for phase 2) When you run a "debug crypto ipsec" on the remote site, I get "no ip crypto card is for addresses local 100.x.x.x" and the VPN remains to IDLE-UP. The ACL on the external interface allows the IP of the remote site. I have CBAC running on the external interface of both routers and ACL permits all traffic between the addresses 100.x.x.x and 200.x.x.x. Could someone help me with the config? I have to do something wrong somewhere.
Thank you!
Shaun

Some comments...
The QM_IDLE means that the phase 1 is established. (sh cry isa his)
You should see with "sh cry ips its" that he has put SAs in place for IPsec encryption/decryption of traffic for the phase 2.
The ACL for VPN (the crypto ACL) should be one mirror of the other (you have "all" on one side and two statements by the other peer network.
You do NAT, therefore, there should be a 'workaround NAT rule' VPN traffic (to remove the IPsec NAT traffic).
This should be it.

Blocks VIRTUAL local network access to a tunnel VPN IPSec on WRV200?
I have two identical WRV200 wireless routers which are connected by a VPN IPSec tunnel. This goes to my LAN LAN of my parents. Everything works well.
But I also have my WRV200 configured for two VLANS. Vlan1 for my network and secure wireless access. VLAN2 for a WiFi not secure for customers.
My problem is that my guest on VLAN2 slips through the VPN devices and access on LAN of my parents. I'm looking for a way to block to do this.
I use the version of the software on the two routers (v1.0.39).
For what it's worth, I know that my receive an IP address in the range 192.168.x.101 DHCP - 199. I could assign a different range if that helps. I thought that I could block this beach on the remote router firewall, but I see there is blocking a single IP address at the time, maximum of 8. Am I missing something?
Or could I put something weird in the routing tables somewhere to get the IPs guest out of lala land?
Any suggestions are appreciated. I can't be the only one in this boat.
Steve
Try to check local and remote, vpn under safe group settings if you change the ip address range subnet. Don't include the range of ip addresses of the computers wireless comments so that it will not pass through the vpn tunnel. If there is no ip range option, you must to the subnet of the network in order to control the ip address you want to allow on the vpn tunnel.

need help with VPN IPSEC with RV042
https://supportforums.Cisco.com/docs/doc-30883
I enjoy any support for a trial with RV042 VPN IPSec game please.
Thanks in advance.
Hi Bay, if you use a Windows computer, you can use QuickVPN. The only thing to note is the router that you have as the gateway to the RV042. You must define a port forward for all IPsec services be able to overcome the problems with the NAT device.
RV042 configuration is easy, create a name of user and password and that's it. The problem/challenge will get your NAT connection to allow VPN pass.

Hi all
I have 3 sites, the main site has a cisco firewall mikrotik router.
There is a vpn ipsec existing between the cisco router and another router cisco on the site of the 2nd and it works well.
Now, I've added an another vpn between a 3rd site and main site. The router on the 3rd site is a mikrotik firewall.
I had the vpn on the main site and the 3rd site where the mikrotik firewall is and it worked well.
then for some reason, the vpn with the 3rd site has failed and I could not get it working again.
When looking for answers, I see that the vpn for the 3rd site States the following:
#pkts program: 46, #pkts encrypt: 46, #pkts digest: 46
#pkts decaps: 0, #pkts decrypt: 0, #pkts check: 0It seems that no traffic is coming back to the cisco
I also found the following output below to diagnose the problem.
It seems that there is communication, but if I read this right, it looks like the cisco established a new number but the other end is not the new number
new node-1868419487

Comparing encrypt of 46 to 47436 counters, it seems that router is ecncrypting the traffic, but we do not get any interesting traffic on the remote side.
Most likely, you might want to check on the remote site, if you see counters increment in parallel decryption and encryption of the counters are incrementing or not.
On the router IOS, if are incrementing counters encrypt, and confirm that you have not any tunnel existing before the router can be seen same proxy IDs, which is already negotiated with other peer.
Finally, please make sure that the ESP, 50 protocol traffic is not blocked in transit.
I hope this helps.Kind regards

GRE tunnels will not come on VPN IPsec/GRE
Hi all
We have 400 + remote sites that connect to our central location (and a backup site) using Cisco routers with vpn IPSec/GRE tunnels. We use a basic model for the creation of tunnels, so there is very little chance of a bad configuration on each router. Remote sites use Cisco 831 s, central sites use Cisco 2821 s. There is a site where the tunnels WILL refuse just to come.
Routers are able to ping their public IP addresses, so it is not a routing problem, but gre endpoints cannot ping. There is no NATing involved, two routers directly accessing the Internet. The assorded display orders seem to indicate that the SAs are properly built, but newspapers, it seems that last part just don't is finished, and the GRE tunnels come not only upward.
The attached log file, it seems that both its IPSEC & ISAKMP are created @ 00:25:14, then QM_PHASE2 end @ 00:25:15.

Hi all
I have a small question. Is it possible to run L2L IPSEC VPN via a subway-E connection? It's not supposed to do something like that with Metro-E but this connection is with a partner so at both ends, firewall is in place. With port forwading, NATting, etc, etc, I came across problems of providing additional services because of it. I hope that IPSEC VPN L2L at both ends will solve this problem once and for all. The only question is of course in fact that a metro-E is just an ethernet connection and not really difference in setting up a VPN IPSEC of L2L via internet.
Thank you for your help.
Eric,
Yes, connection L2L IPSEC VPN Tunnel Over Metro-E should work perfectly. You might meet in the treatment of air issues and the flow on the VPN server but it should be good.
Kind regards

VPN/IPSec-L2L - Question?
Hello!
Recently, I was doing some troubleshooting on a connection VPN/IPSec Lan-to-Lan between a Cisco PIX515E and a Linux firewall. My question concerns the configuration and is not the problem itself.
Traffic interesting (encrypted traffic) defined and configured the LAN of PIX (inside) and the distance public IP? Which means that the Peer IKE and the interesting remote control LAN/IP are the same... and it works!
Any ideas?
Thank you
JP
As long as you source the package from the local network of Pix to remote public IP, the tunnel will work well and works :-)
So, if you really look at the fluidity of the traffic, you're sourcing traffic from Pix LAN intended to public IP remote that corresponds to the defined access list. Thus, the pix knows he has encrypt traffic and now seeks the cryptographic endpoint points (pix outside IP public IP remotely) and sends the encrypted packets. So, this configuration works perfectly.
In fact, Pix will not allow Telnet the external of the pix interface unless the traffic is through an IPSEC Tunnel and it was one of the establishment who gave a telnet access to the external interface of the Pix, it's LAN to the public IP of Pix through an IPSEC Tunnel.
Kind regards

Hello
I have 2 questions about vpn IPsec
I have an asa, vpn ipsec (l2l) running on a remote site with 192.168.0.0/24 network
1 > I can ping 192.168.0.1 but not 192.168.0.111. I had observed "Recv errors" whenever I have ping to 192.168.0.111.
I had observed recevied errors of "crypto ipsec to show his" exit; but not because the tunnel to reconnect (after timeout) and w/o any changes made to the configuration.
What could be the cause and how can I fix just in case where the returned errors? I can't find much info on "recv errors."
2 > I understand there are 2 acl required for a vpn ipsec typical; 1 for no NAT, 1 correspondence address card crypto
can I implement an acl to allow tcp 3389 only from the remote network on my local network on the asa?
Thank you
cash
Salvation of cash,
There is not a lot we can do here in what concerns this isuse.
You can talk to your service provider and see if they do not modify the packets somehow.
Also ask them to check for any problem on the circuit.
See you soon,.

ASA ASA from Site to Site VPN IPSec Tunnel
Any help would be greatly appreciated...
I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.
Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24
Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24
Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.
Internet access works very well in all workstations of this site. A static route is configured to redirect all traffic to a public router upstream.
Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address. A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA. A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253. This device then performs its own private Public NAT. Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)
The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24). The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254). The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem. However, all traffic passing on networks ICMP does not end and the Syslog reports the following-
Site #1-
6 January 19, 2011 15:27:21 302020 ZEFF-SB-01_LAN 1 10.1.1.51 0 Built of outbound ICMP connection for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1 6 January 19, 2011 15:27:23 302021 10.1.1.51 0 ZEFF-SB-01_LAN 1 Connection of ICMP disassembly for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1 Site #2-

The ACL is configured to allow segments of LAN out to any destination. At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).
Anyone can shed light on a possible cause of this problem?
Thank you
Nick
did you bypass the vpn traffic between 10.0.0 and 10.1.1 to be NAT - ed on the two ASA?
Please provide the following information
-set up the tunnel
-show the isa cry his
-show the ipsec cry his
-ping of the site 1 site 2 via tunnel
-capture "crypto ipsec to show his" once again
-ping from site 2 to 1 by the tunnel of the site
-capture "crypto ipsec to show his" once again
-two ASA configuration.

Site-to-Site VPN IPSEC falls intermittently
Site-to-Site VPN IPSEC falls intermittently
I am currently having a problem with a VPN from Site to Site traffic not only not intermittently. When the problem occurs, I can't Ping the remote site to the AC Site. But I can solve the problem by Pinging from HQ at the Remote Site. My network is currently configured as follows
-------HQ------
7.0 (4) version of pix 515 with card Ethernet 4 ports.
Outside of the interface connected to the Broadband DSL link.
Outside2 Interface connected to the second link DSL broadband
-Distance-
I have 4 Remote Sites. 2 sites connect you to each connection to wide band at HQ to spread the load to HQ
6.3 (5) pix 501 version
# The problem #.
All VPN establishes successfully to the HQ Pix
Intermittently, a remote site will report that they cannot connect to servers/services in the HQ. When I do a show crypto ipsec's and see the crypto isakmp his headquarters there is no entry for the remote site. However when I do the same on the remote site there is an entry for the HQ. With debugging on the remote site pix I try to ping from a pc to the HQ server and I get the following (see below). If I do a "ipsec Isakmp security association claire crypto ' and ' clear crypto ipsec his ' on the pix of remote site, then I can successfully ping all servers in headquarters.
This problem seems to have taken place only when I upgraded the pix of a 501 to 515 and added another 2 remote sites and a second broadband, as described above. I'm afraid that there is a problem with software version 7 Pix. Any advice would be greatly appreciated.

Site to Site VPN IPsec IPv6 on issue of routers-Tunnel
Hi, I am experiencing a problem can any one address the question below and let me know the solution. I have two routers and try to build "Site to Site VPN IPsec IPv6". I followed orders from Cisco and community document but when I apply my profile of ipsec for tunnel interfaces, that the tunnel is down.
https://supportforums.Cisco.com/docs/doc-27009
Ali,
VTI tunnels are meant to be broken when there is no active negotiated spinnakers.
The tunnel will go towards up/face upwards when there is a means of transport of packages - i.e. the SPIs are present.
You can control the order spinnakers 'show peer's crypto ipsec '.
For debugging:
Debug crypto isa
Debug crypto ipsec

Cisco ASA Site to Site VPN IPSEC and NAT question
Hi people,
I have a question about the two Site to Site VPN IPSEC and NAT. basically what I want to achieve is to do the following:
ASA2 is at HQ and ASA1 is a remote site. I have no problem setting a static static is a Site to IPSEC VPN between sites. Guests residing in 10.1.0.0/16 are able to communicate with hosts in 192.168.1.0/24, but what I want is to configure the NAT with IPSEC VPN for this host to 10.1.0.0/16 will communicate with hosts in 192.168.1.0/24 with translated addresses
Just an example:
N2 host (10.1.0.1/16) contacted N1 192.168.1.5 with destination host say 10.23.1.5 No 192.168.1.5 (notice the last byte is the same in the present case,.5)
The translation still for the rest of the communication (host pings ip destination host 10.23.1.6 N3 N2 not 192.168.1.6 new last byte is the same)
It sounds a bit confusing to me, but I've seen this type of configuration before when I worked for the supplier of managed services where we have given our customers (Ipsec Site to Site VPN with NAT, don't know how it was setup)
Basically we contact the customer via site-to-site VPN hosts but their real address were hidden and we used as translated address more high 10.23.1.0/24 instead of (real) 192.168.1.0/24, last byte must be the same.
Grateful if someone can shed some light on this subject.
Hello
OK so went with the old format of NAT configuration
It seems to me that you could do the following:
- Configure the ASA1 with static NAT strategy
- access-list L2LVPN-POLICYNAT allowed ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
- public static 10.23.1.0 (inside, outside) access-list L2LVPN-POLICYNAT
- Because the above is a static NAT of the policy, this means that the translation will be made only when the destination network is 10.1.0.0/16
- If you have for example a PAT basic configuration to inside-> external traffic, the above NAT configuration and the custom of the actual configuration of PAT interfere with eachother
- ASA2 side, you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
- Note of the INTERIOR-SHEEP access-list SHEEP L2LVPN
- the permitted INSIDE SHEEP 10.1.0.0 ip access list 255.255.0.0 10.23.1.0 255.255.255.0
- NAT (inside) 0-list of access to the INTERIOR-SHEEP
- You will need to consider that your access-list defining the VPN encrypted L2L traffic must reflect the new NAT network
- ASA1: allowed to access-list L2LVPN-ENCRYPTIONDOMAIN ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
- ASA2: list L2LVPN-ENCRYPTIONDOMAIN allowed ip 10.1.0.0 access 255.255.0.0 10.23.1.0 255.255.255.0
I could test this configuration to work tomorrow but I would like to know if it works.
Please rate if this was helpful

Here are a few suggestions:
change this:
radius of group AAA authorization network groupauthor
for this
AAA authorization groupauthor LAN
(unless you use the group permission for your radius server you need local)
Choose either on ISAKMP profiles and if you decide to go with and then get rid of these lines:
map clientmap client to authenticate crypto list userauthen
card crypto clientmap isakmp authorization list groupauthor
client configuration address map clientmap crypto answer
AND change the following items on your profile isakmp:
Crypto isakmp VPNclient profile
ISAKMP authorization list groupauthor
Also if you'll use a list for user authentication, I advise you to avoid using the default list so go ahead and change it too much under the isakmp profile
