If you have a headsite with multiple EZVPN clients (PIX 501 & 515) connected in a star configuration can you have one remote site connect to another remote site using the intra-interface command and modifying the encryption domain on the EZVPN Server?
View 3 RepliesI'm working with AnyConnect for the first time (my prior experience is with IPSec client) and I have multiple remote users who connect to a 5520 via AnyConnect client; they need to print to each others' shared printers but currently have no connectivity between each other.
Can I configure the 'intra-interface' command to enable connectivity between remote clients, or is there more that needs to be done to enable this, presuming that it can be done at all?
Recently, I deployed ASA 5520 as our company firewall, everything was working fine except two main problem I still can not resolve them after I did a lot of research.
1. DNS rewriting - The internal user can not access the DMZ or internal server by put in the domain or external ip address. such as [URL] will resolve our wan ip address 210.0.0.83 ( internal ip address is 192.168.1.21 ).I used static (inside,Outside) tcp 210.0.0.83 https 192.168.1.21 https netmask 255.255.255.255 dns, but it will not work. We have our internal DNS server, but don't want to just add the domain as a record. Is there anyway to get the internal user to access Internal server and DMZ server through the public domain?
2. We also have an internal multiple subnet, another router was conneting to ASA firewall inside interface and using ip address 192.168.1.223, another subnet 10.1.15.16/28 is behind the this router, for the users in subnet 192.168.1.0/24, they connect firewall inside interface directly.I added an static route and intra-interface permit route inside 10.1.15.16 255.255.255.240 192.168.1.223 1same-security-traffic permit intra-interface I also added access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 10.1.15.16 255.255.255.240access-list inside_nat0_outbound extended permit ip 10.1.15.16 255.255.255.240 192.168.1.0 255.255.255.0nat (inside) 0 access-list inside_nat0_outbound The internal users on 192.168.1.0/24 can ping 10.1.15.18 but can not telnet to 10.1.15.18 22. If I set 192.168.1.223 as one of the workstation on 192.168.1.0/24 default gateway, it can telnet to 10.1.15.18 22 without any problem.
I have lots of 857's routers in the field with mostly the latest OS - 12.4(15)T17 making ezVPN connections to a 2951 with 15.1(4)M5.All the 857's have lookback and vlan interfaces similar to :
interface Loopback0
ip address 50.43.8.1 255.255.255.255
ip tcp adjust-mss 1452
end
[code]....
Now lately for some or other reason we have instances where I can ping either the VLAN or the LOOPBACK interface, but not both. Or I have instances where the 2951 can ping all the interfaces on the 857, but the 857 can not ping the 2951. Or I have instances where the 2951 can not ping the 857, but the 857 can ping the 2951.The way I have been fixing this is either to add crypto ipsec client ezvpn SMS_VPN inside to the loopback interface, or if it is there already to remove it. This usually works for a few days, but then suddenly I have to reverse this again. If that does not work then I usually do lots of clear crypt sess and/or clear crypt ipsec client ezvpn on the 857, or clear crypt sess remote 857_ip_address from the 2951 and then suddenly it starts working again.
I have setup DMVPN and EAZYVPN on one router. Tunnel interface on Spoke one and Spoke two are up/up and show crypto ISakmp sa shows both tunnels are in idle. However, tunnel to Spoke one(10.10.1.1) keep bouncing on and off(see below). Every 30 sec or so, the tunnel gone back to IKE phase while tunnel for spoke two(5.5.5.1) still leave active. THe configuration on the HUB side is the same for both spoke!! show crypto ipsec sec shows both side has the same life time(IOS default). Could that be an IOS debug on the spoke one?

I try to set up EZVPN server. I cannot get any response from server.
View 1 Replies View RelatedWe have a VPN using 857 and 877 routers as remote connecting in to a 2800 EZVPN Server.
The VPN is working fine. However, the VPN connections sometimes (after a few hours/days) seem to "freeze". A "show crypt sess" shows the connections as Up/Active, but you can not ping antyhing from remote to server, or visa versa, nor does any traffic flow. I then added a "isakmp keep-alive" on the 2800, which improved the situation a bit, but not as much as I hoped.
On the 877 I then implemented a IP SLA, with Object Tracking and then use a Event Manager to just issue a "clear crypto session" . This solved the problem.
However, what do I do on the 857 ? It does not support Object Tracking or the Event Manager. Is there any other mechanism to monitor and reset these frozen/stale VPN connections automatically ?
I have the following problem on configuring ezvpn for the following situation: 3 different locations - 1 HQ with 2901 server and 2 offices with 861 clients.

I was using command prompt and typed in netstat -a to see opened ports on my XP computer. Then I found a weird result I have never seen it before.
It was Proto local address Foreign address state
TCP myXP computernameort# 192.168.1.1:domain Fin_Wait_2
What does this 192.168.1.1:domain mean? I believe 192.168.1.1 is my gateway router, but why it says :domain? few minutes later, I typed netstat -a in the command prompt to check it again, but it wasn't there anymore. does this mean my computer is on a domain network or something? As far as I checked, my computer doesn't seem to be on a domain network, but I just don't know what it means.
i am going to configure asa5505 as the azvpn client . and configre primay and secondary vpn server in the list.i find some feature that is support by ios ROUTER ezvpn, not sure it will be support on ASA ezVPN???
will the ezvpn fall back to the primary vpn server , if primary back on line, on ASA? The Reactivate Primary Peer feature allows a default primary peer to be defined. The default primary peer (a server) is one that is considered better than other peers for reasons such as lower cost, shorter distance, or more bandwidth. With this feature configured, if Easy VPN fails over during Phase 1 SA negotiations from the primary peer to the next peer in its backup list, and if the primary peer is again available, the connections with the backup peer are torn down and the connection is again made with the primary peer.
i've been using a VPN to connect to my home network from elsewhere for a few months. It's set up as follows:
PPTP
Maximum Strength Encryption
EAP-MSCHAP-v2 Authentication
Now I find out that MSCHAPv2 authentication has been broken and is no longer considered secure (even by Microsoft), so I want to change the protocol I'm using to make it secure.
However, I've spent 3 hours now researching this and I cannot for the life of me figure out how to use a better protocol on my Windows Server 2012 home server. I've tried setting up PEAP authentication (still PPTP) a la Microsoft's recommendation document, but it requires a certificate. I've created a self-signed certificate but it seems I can't issue certificates (via this method) without being a member of a domain, so I'm stuck. I can't even get started with L2TP since I can't find the option for it.
My question is this: Is there a way to setup a secure VPN server using Windows Server 2012 without a domain? If so, how do I do this?
i configured cisco asa 5520 as cisco ezvpn server and cisco 891 as ezvpn client .the configurtion is working fine.i am using client mode on the ezvpn client side.but my quesion is , is it possible to communicate to ezvpn client side internal ip from the ezvpn server side?and one more thing what is the benefit of network extension mode on the client side and how it will work what are possible changes need to do in the server and the client side.

I can ping and connect to servers by IP address from my workstation. However, Sys Admin wants everyone to use the DNS name instead. The only way I know to add DNS names is to modify the host file on the workstation. Sys Admin has forbidden users from modifying their host files.
How else can I map these IP addresses to DNS on a Windows 7 machine?
I have tried modifying the domain, thinking I can use the DNS entries on the domain server. Did not work. If this should be working maybe I'm not using the right domain? Any way to determine what domain to use?
I am decent in using command line, feel free to give non-GUI based answers.
Notes:
- I do know how to modify host files, including the Windows 7 work-around for having this locked out. But it's a "rule" by the Sys Admin not to do it. So I'm trying to adhere to the policy
- Sadly, asking the Sys Admin for the alternative tactic is not an option. Lame but true.
- I have scoured the internet for info on this issue. Everything I find either involves modifying files or enabling services on the server, or modifying the host file on the workstation. Even looking at the server settings is out (I don't have access).
How to host my website from home? So I am half way through this process. I have created a domain name [URL] I have used zoneedit's free DNS server as I cant be bothered setting one up for what I want to do. Now I have my external ip "eg.eg.eg.eg" which i entered into the configuration on zoneedit. I then typed www.mydomainname.net.au into google chrome and I am prompted for my Thompson gateway (my modem/Router) username and password. This I enter and i find my self being able to configure the settings for my router over the internet from my domain name....this makes me go huh? I also tryed using the free dyndns.org with exactly the same results. I have no idea what I am supposed to do next anyway. Btw the website I am trying to host is a Joomla 1.6.3 so I would need to run a WAMP Server as well, but if I have troubles with that I can ask the Joomla Forums.So my main question is what on earth do I do now. Perhaps I need to do something with the ports or settings in my router, and where do I even put the files for the wesite and I do not mean to insult anyone I just don't want to be plainly stating my external ip on the web (i know it is visible on any website i go to) whilst it is linked to my router settings.
