VPN site to Site, Phase 2 is do not fit correctly and no connectivity
Hi all
I am facing a problem with configuring VPN from Site to Site of my HO one of the remote site.
My remote site got the subnet(192.168.10.0/24) LAN, we use also in HO. Remote site wish to access certain servers in HO 192.168.200.0/24&192.168.80.0/24.So we did a NAT policy distance from the ASA 192.168.10.0/24 subnet remote site to 192.168.175.0/24 translation site while reaching the end of the HO.
The VPN the two phases are coming, but not able to reach my iam connectivity. I can see are encapsulating the packets from the remote site and decapsulating in HO, but opposite side does not (i.e. no encapsulation at the end of HO) & no decapsulation at the end of remote site.
a question, I noted at the end of HO "sh crypto ipsec his" shows a different card is attached to it. This cryptomap we have for our remote access VPN is displayed in the ipsec his. Please see the configuration and the output below...
Tag crypto map: non-retail-VPN, seq num: 3, local addr: x.x.x.x
local ident (addr, mask, prot, port): (192.168.200.0/255.255.255.0/0/0)
Remote ident (addr, mask, prot, port): (192.168.175.0/255.255.255.0/0/0)
current_peer: x.x.x.x
I can see hits on my crypto access list, and the two phases are coming. kindly help to solve the problem...
Thanks in advance...

Hello
Clearly, the connection is managed by another card crypto bein.
Check those:
-Where your ASA rounting the destination network. (192.168.175.0 network)
-L' outgoing interface that uses the path has a card encryption? THAT IS "NON-RETAIL-VPN.
-If it is rounting to the wrong interface try reconfigure the route to this destination.
This is most likely your problem. Or at least one of them.
Rate if this can help.

Thomas Thomann (thomann.de) are among other things, the online musical instrument suppliers. I visited their site several times and they list products with 'our price' (in Euros) and a title of sup in GB pounds. Just like tech sheet. descriptions of products etc. are expected except no prize not collected (or in Eur or GBp) number I often complains that I couldn't compare prices I covered products and they said it must be a problem "with my browser settings" I have not had a similar experience on other websites where I do fairly regular purchases , my browser settings should be OK.?
I checked the website and they seem to be using a GIF (sprite) and use the CSS code to display a specific number of this sprite to dial the numbers that display prices.
So make sure that you do not block the CSS on this site to make it work.

My site is not displayed correctly on firefox, but works well on other browsers
My site: www.karposveg.com is not displayed correctly on firefox. I have created some social media icons, but all of a sudden they started to display as hyperlinks or words out and get out. It's frustrating because it works perfectly well on other browsers, but I'm used to sort of mozilla. What exactly is the problem?
The images are present on your own server:

The sides of my layout of the Web site are not aligned correctly, and the image is slightly moved above.
To much better understand what I mean... First discovered my site here: http://www.clanmog.hostei.com/ - I noticed that this problem only occurs in Firefox (to my knowledge) and not Internet Explorer. It does not have this in IE, but Firefox does.
then look at this image: http://img261.imageshack.us/img261/7210/helpme.PNG
How can I solve this problem?
At a glance I'd say it's because you are clearing out the average divs, but not others. This changes the alignment calculations...

IPSec VPN Site-to-Site router Cisco 837 to Firewall FortiGate 200 has
I had a challege for a site to site vpn scenario that may need some brainstorming you guys.
So far, I have had a prior configuration planned for this scenario, but I'm not very sure if the tunnel I created will work because I did not test it before with this scenario. I'll go next week on this project and hopefully get a solution of brainstorming you guys. Thanks in advance!

Hello
Three changes required in this configuration.
(1) change the NAT-list access 102 as below:
access-list 102 deny ip 10.20.20.0 0.0.0.255 172.20.10.0 0.0.0.255
access-list 102 permit ip 10.20.20.0 0.0.0.255 any
(2) place the card encryption on interface point-to-point ATM.
(3) remote all of a default route.
Thank you

Hello
I built a VPN site-to site with an external company. I use a Cisco ASA 5500. We have the installer, the encryption phase settings 1 and 2 on both sides, but I don't see on the follow-up is that he connects for 1 second and then disappears again
Tx0
Rx0
Any ideas why this is?
All my other site-to-site VPN work very well.
Kind regards
Kevin
Hey Kevin,
If you are familiar with the console of the ASA, you can run him debugs below for more information on this issue.
Debug crypto conditions counterpart x.x.x.x
Debug of ikev1 127 crypto (isakmp older versions)
Debug the crypto ipsec 127
It may be useful

Hi all, I have two sites in central administration, I have a C2801 as hub and in the remote part, I have a C1861 as it is get the IP through ADSL, after I configured the two rtrs, all stages of phase 1 is complete, the next step, I get the IKMP_ERR_NO_RETRANS error, I read a lot of entries here , but none are like the one I have.
Please check if I missed some in the configuration. Another thing is that in the same C2801 I got a VPN Client and other vpn site-to-site, with a fixed IP address and work perfect.
Side remote network: 192.168.225.0/24 and 192.168.226.0/24
HQ networks: 192.168.0.0
I have attached the configs and debugs.
Fixing of work (for me) configuration + debugs.
Both star are 12.4 (22) T1

VPN site-to-site initiated in one direction
Hello. We try to establish a VPN site-to site between two ASA firewalls, let's call them ASA1 and ASA2. Problem is that ASA1 cannot start the connection. ISAKMP of ASA1 packets reach ASA2, but removed by an unwritten rule.
When ASA2 launches, everything is OK. And while the stream exists on ASA2, ASA1 use flow, so he can start VPN also.
Here's the output of packet - trace on ASA2:

Using tracers of package in ASDM has not point to any specific rule, he just showed the entire list of the ACL rules. Using asp-menu type capture displays the reason of gout as packet-tracer, without more details. ASA2 layout only response did not help.
How to interpret the values of phase 4, i.e. to find the rule that causes drops, based on the id and other data? There is no such id in HS to access lists.
Any other ideas? Thank you very much.
And an idea more :)
Maybe you have something like this on ASA2:
Access-group outside_access_in in interface outside control plan
?
Keyword group-access-control-plan sentence, traffic, which is aimed at the interface of the ASA, may be filed. Please, see the following discussion:

Try to ping of PC - A (172.16.8.1) PC - C (172.16.40.1) does not work.
I tried several times to get the traffic through the tunnel with no success. Can someone tell me where I'm wrong?
Thank you
Josh
Hi Josh,.
Around this deployment, you will not be able to ping or reach the other side because of the NAT, NATting is dynamically IP addresses, you must do the following:
R! :
no nat ip inside source list ADDRESSES interface Serial0/3/0 overload
no standard ip access list ADDRESSES
permit of 172.16.8.0 0.0.7.255
IP extended access.list ADDRESSES_NAT
refuse the 172.16.8.0 ip 0.0.7.255 172.16.40.0 0.0.7.255
overload of IP nat inside source list ADDRESSES_NAT interface Serial0/3/0
R3:
no nat ip inside the overload of source list ADDRESSES interface Serial0/3/1
no standard ip access list ADDRESSES
172.16.40.0 permit 0.0.7.255
ADDRESSES_NAT extended IP access list
deny ip 172.16.40.0 0.0.7.255 172.16.8.0 0.0.7.255
IP nat inside source list ADDRESSES Overload: NAT interface Serial0/3/1
with this show commands you make to phase 1 and phase 2 is in place and work:
-show crypto isakmp his
-show crypto ipsec his
I hope this helps!
Please note and mark it as correct the helpful post!

Static - VPN Site to Site DMVPN Tunnel
Hello
I have two sites, Site-a with Cisco ASA 5505 static IP Configuration & Site-B 1841 Cisco ISR with dynamic IP Configuration.
See the diagram attached for a glimpse.
The goal is to have the tunnel VPN Site to Site between the site of two so that desktop sitting in Site B can access the server applications residing in the Site-A.
Please suggest

@Mohammed
Hello
A site to Site IPSec, the ASA is the static side and he should have the 'dynamic' configuration, and the side Dynamics SRI 1841 should have the static side:
I'll give an example configuration to achieve, but you can use a different encryption algorithms:

Phase 1:
