ASA 5510 and VPN access to remote site over Ext WAN

ASA 5510
int client IP 172.0.1.XXX /24
VPN Client IP 172.0.1.248 /29
Static routes in the ASA
1) 0.0.0.0 --- points to router1
2) 172.29.1.1 --- Points to router2
3) 172.29.1.2 --- Points to router2
Router1 Internet connection // VPN access in path
Router2 Dedicated line to offsite hosting // Dedicated routes in ASA
................../---- ROUTER 1
..Inside -- ASA --- outside (switch 2 rtrs)
..................\---- ROUTER 2
If a PC from inside the network wants to talk with 172.29.1.2 it will work fine. If I VPN into the router, I can connect to anything onsite. I cannot talk to 172.29.1.1 or .2
At first I thought it was the same-security-traffic issue and applied same-security-traffic permit inter-interface then i tried same-security-traffic permit intra-interface.
Both commands failed, Looking at the diagram I think its something with the fact I VPN into this ASA. Now router2 see's our ASA as its external. So it see's our 208.12.*.* as the outgouing address and dest is 172.29.1.1 or .2
I did a capture on the outside interface and I see the following. Now these caps are from the inside PC's accessing the website.
3000 packets captured
1: 15:03:38.176733 208.12.*.*.60404 > 172.29.1.2.443: P 2697372408:2697372444(36) ack 2813073572 win 64360

Can someone point me in the right direction on how I would get the VPN working so it too can connect to those websites?

Hi,
Did you try to do NONAT for the traffic from 172.0.1.0 going to 172.29.1.0
Something like this:-
access-list NONAT permit ip 172.0.1.0 255.255.255.0 172.29.1.0 255.255.255.0
nat (Inside) 0 access-list NONAT

Questions regarding Outlook Web App, Remote Desktop, Remote Web Access and VPN Access

Hi there,
I want to ask a series of questions regarding Outlook Web App, Remote Desktop, Remote Web Access and VPN access and was hoping whether you could help me. Below are my questions to ask you.
Outlook Web App - What do I need to configure in order to get my Exchange account to work with the OWA app on my iPhone? Is Office 360 required on the server that hosts Outlook Web App in our organisation? When I configure the settings and
connect I get the following message "couldn't connect - We couldn't connect to the server. Check your information and make sure it's correct." I can connect with other devices using Outlook Web App.
Remote Desktop - What do I need to configure in order to connect to my computer at work using Remote Desktop on my Windows Phone? When I configure the settings and connect I get the following message "Connection error - We couldn't connect
to the remote PC. Make sure the PC is turned on and connected to the network, and that remote access is enabled. Inquiring minds may find this error code helpful: 0x204" I can connect with other devices using Remote Desktop. There are currently no
RD Server settings in the Remote Desktop app on the Windows Phone and the only way I'm to connect to my PC at work is via Remote Desktop and not to be confused with the one by Microsoft, however the app is on a trial basis and times out every 5 minutes and
can only be used once every hour unless I purchased the app for £2.99 off the App Store but would ideally like to use the Microsoft Remote Desktop app though.
Remote Web Access - What do I need to configure in order to get Remote Web Access on my Windows Phone using a URL? When I log in using a URL I get the following message "There is a problem with this Web page. Please contact the person who manages
the server" I can connect with other devices using Remote Web Access. Also how do you enable the background option for Remote Web Access? I know how to do this in Remote Desktop but not in Remote Web Access. Remote Web Access works on PCs regardless
being onsite and offsite and on my iPhone, the same issue also occurs with my Nokia 5230s regardless of whether I'm using Opera Mobile or Mini or the latest Nokia Browser.
VPN access - How do you configure VPN access on a Windows Phone using VPN? I cannot find the protocols PPTP, L2TP, SSTP and IPsec in order to configure VPN access on the Windows Phone apart from IKEv2.
Many thanks,
RocknRollTim

Any help would be much appreciated.

REMOTE RECORDINGS OVER THE WAN IN CCX 7

We have a customer
with CCX 7 local agents and recording services ( BUT NO QUALITY MONITORING)
Normally records all local agents calls ( colocated with CCX.
Now customer has remote agents via WAN and needs to record their conversations.
According specifications and PDI case the sutiationis:
"This deployment model can support silent monitoring and recording for agents at any WAN-connected site by using desktop monitoring. (Refer the Cisco Unified CCX Software and Hardware Compatibility Guide for a list of phones that support desktop monitoring). It can also support SPAN port monitoring for agents on the VLAN segment local to Cisco Unified CCX server. This deployment model does not incorporate additional remote Monitoring components, so silent monitoring and recording is not possible for agents who are using the Cisco IP Phone Agent at remote sites. Similarly, silent monitoring and recording is not possible for agents at remote sites who are using phones that do not support desktop monitoring."
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_7_0/design/guide/uccx70srnd.pdf
page 4-6
The list of phones not supported for desktop monitoring is listed in the compatibility guide.
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_compatibility/matrix/crscomtx.pdf
In other words CCX can support "silent monitoring and recording for agents at any WAN-connected site by using desktop monitoring"
But assume you use an IP Phone that supports desktop monitoring
AS RECORDING OPTION WITHOUT QUALITY MONITORING NEEDS MAC ADRESS OF AGENT how can CCX record agent calls taking into accoutn that MAC address is lost when traversing the WAN ...
So the question for this dsicussion is :
IS QUALITY MONITORING THE ONLY WAY TO RECORD REMOTE AGENTS OVER THE WAN OR ARE TEHRE OTHER OPTIONS WITHOUT IT??
Pease reply to [email protected]

It is possible without QM. When using desktop monitoring, the phone is configured to Span to PC port. The agent must be running CAD and the PC running it must be attached to the PC port on the phone. CAD sees the spanned packets from the phone and then forwards them to the recording service on the CCX server. The big gotcha is that the NIC in the PC must not discard 802.1q-tagged packets. If the NIC discards them instead of forwarding them into the NDIS stack, CAD will never see them. Sometimes this takes a Google search and a registry setting change to fix if it doesn't work at first.

Using ASA 5510 and router for dual WAN Connections.

Guys, neeed some help here:
Context:
1- My company has one ASA 5510 configured with Site-to-site VPN, Ipsec Cisco VPN and AnyConnect VPN.
2- We use ASA to connect to the single ISP (ISP 1) for internet access. ASA does all the NATing for internal users to go out.
3- A second link is coming in and we will be using ISP 2 to loadbalance traffic to internet (i.e. business traffic will go via ISP1 and “other” traffic will go via ISP2).
4- A router will be deployed in front of the ASA to terminate internet links.
5- No BGP should be used to implement policy (traffic X goes via ISP1, traffic Y goes via ISP2).
Questions:
How do I get this done, particularly, how do I tell the router, for traffic X use ISP1 and for traffic Y use ISP2? PBR is my friend?
Since I will be having 2 public Ip Addresses from the 2 ISPs, how do I NAT internal users to the 2 public Ip addresses ?.
Finally, which device should be doing the NATing? The ASA just like now or move NATing to the Router?
Thanks

Hi,
Check the below link, it gives information on trasperant fw config and limilations. Based on the doc, you may need to move the VPN /anyconnect to router as well. From the routr end you may be able to set up static routes pointing to diff ISP based on traffic needs but this will be compleicated setup and can break things. Wait for other suggestions or if possible stick to ASA to terminate both links and still route the traffic to diff ISPs (Saves the router cost as well).

ASA 5510 Anyconnect VPN question-"Hairpin" vpn connection on same external interface

I have a Cisco ASA 5510, I want to allow a VPN connection to be established by a client on one of the inside interfaces(10.20.x.x) to be able to go out the single External interface and get authenticated by the ASA to create a VPN tunnel to the other inside interface (10.0.X.X) and access resources on that subnet.
Basically want clients on a WLAN to be able to VPN back in to the LAN with the ASA in the middle to get to company resources,
Is this possible?
Thanks,
Tommy

When we connect any VPN on a device then it is always a TO THE DEVICE connection and I am afraid we can connect only to the local / nearest interface where user is connected in a network with respect to ASA.
I have seen this scenario working though earlier with one of my clients wherein he has configured his DNS server accordingly so that depending upon the source of the DNS request an appropriate IP address was provided for same DNS name. For example if user from IP address range 192.168.0.0 range connects to abc.com then it will get IP address 192.168.1.1 and if a user from range IP address10.0.0.0 connects then it will get 10.1.1.1.
If we configure the same scenario as well then your requirement will be fulfiled with same name however VPN has to be enabled on wireless interface again. If not, then as you have described configuring a new domain name for VPN connection only for wireless users should do the deal.

Anuj

Communication problem between ASA 5510 and Cisco 3750, L2 Decode drops

Having problem with communication between ASA 5510 an Cisco Catalyst 3750.
Here is the Cisco switch port facing the ASA 5510 configuration:
interface FastEthernet2/0/6
description Trunk to ASA 5510
switchport trunk encapsulation dot1q
switchport trunk native vlan 50
switchport trunk allowed vlan 131,500
switchport mode trunk
switchport nonegotiate
And here is the ASA 5510 port configuration:
interface Ethernet0/3
speed 100
no nameif
no security-level
no ip address
interface Ethernet0/3.500
vlan 500
nameif outside
security-level 0
ip address X.X.X.69 255.255.255.0
There is a default route on ASA to X.X.X.1.
When I try to ping from ASA X.X.X.1 i get:
Sending 5, 100-byte ICMP Echos to 31.24.36.1, timeout is 2 seconds:
Also in the output of show interface eth 0/3 on the ASA i can see that the L2 Decode drop counter increases.
I have also changed the ports on the Switch and ASA but the same error stays.
Any thoughts?

I don't see anything wrong with your trunk configuration; I have a similar one working between an ASA 5520 and a Catalyst 3750G.
Maybe you should adjust the "speed 100"? In my experience, partial autoconfiguration results in duplex mis-matches, which results in dropped packets.
I'd try removing the "speed 100" and letting the ASA port autonegotiate with the switch. Alternatively, have both sides set
speed 100
duplex full
and see if things improve.

How to access a remote site in dreamweaver

This might seem like a simple question, but i just downloaded DW as a trial, and want to try it out before buying. Now I've done the remote site set up and tested and it says it can connect to my remote site. But I want to now go to the site, log in, and make some changes to the web site pages which are stored there. None of the stuff is stored on my home PC. It's all at the remote site. So how do I edit it? How do I even log in? DW seems intended to work on files on your home PC, and then publish them to a remote site. My problem is it's all ON the remote site.

Hi Nancy,
No, I'm not getting those selections under the file menu. What I've done is go to server, manage servers, and set up a remote server. When I test it it says "dreamweaver connected to your web server succesfully". So I assume that the remote server, at least, is set up properly. I didn't set up a "local site" however. Perhaps that could be it? But those choices are not on the drop-down box, even grayed out. If I click on "open" the box goes to my PC for choices. On the left side it has" My recent documents, desktop, my documents, my network (which doesn't lead anywhere)

Replacing ASA 5510 and ARP

Hello Support,
Probably an easy question and may be buried within these forums (but I can't find it).
I'm attempting to replace a 5510 with another 5510 and having all sorts of difficulty. Devices the PAT against the outside interface have no problems getting out, but anything with a 1:1 NAT cannot. Screams of an ARP issue; however rebooting the switch and the firewall have no effect. Is there something else I could potentially be missing. Configurations are completely mirrored. And the firewall the I'm trying to replace has no issues getting out with 1 to 1 (static) nats. Any ideas?

Hi,
If you are talking about normal L2 switches with no routing capabilities then rebooting them might not do anything. I guess usually if you replace a device that is connected directly to some routers then the simple fact that the interface will go down is enough to "flush" the ARP table on the connected devices and the replacement of the device goes smoothly.
If you ASA is connected to the ISP through a L2 switch there is always a chance that the rebooting of the switch wont bring down any link on the ISP side and remove the old ARP table information.
I am also not quite sure if and when the ASA uses Gratuitous ARP which is meant to update the ARP table of the connected devices.
But I would have to say that its not that uncommon that some people face problem with replacing devices and the ISP still having the old ARP information on their end. As I personally work for the ISP and usually am the person who handles the firewall replacement, its pretty easy to handle both the ISP side and the customer side.
Usually the the firewall that I replace is also connected directly to some LAN router so the routers interfaces naturally go down during the device switch and I wont have to resort to any ARP clearing on the LAN side.
Even though it might be basic information, I am actually not sure how long the basic PC keeps the ARP table information. Though I would imagine Google might tell me pretty quickly

Connection from remote sites (Frame Relay WAN) to AS/400 dissapears

Hello,
We have the following problem appearing in our environment:
All connections from remote sites dissapears unexpected from AS/400. After 2-3 minutes remote users get normal connectivity again.
The environment is the the following:
Frame Relay/ATM WAN (Frame Relay on remote sites and ATM in datacenter) comes to Cisco 7204VXR router which connected to LAN switch with 10/100/1000 ports. AS/400 with Fast Ethernet interface also connected to the similar LAN switch. CEF is enabled on the router, IOS version 12.4.3a. We have ETHSTD *ALL parameter set on AS/400. Remote users uses TCP/IP and Telnet but there are a number of 5494 controllers wich uses SNA.
We got the problem for the first time after we enabled CEF on the router.
I suspect that the cause of problem is Ethernet frames of different standards due to ETHSTD *ALL, but can neither reproduce the problem nor understand why it behaves so.
Have anybody had similar problem?
I would be very thanksfull if somebody can help me to solve it.
Thank you in advance.
//Mikhail Galiulin

Hi Martin,
Cisco 7200 itself can access AS/400 as well as all other hosts in the same with AS/400 LAN. There is no any outage in communications which goes to another LAN segment via Netscreen firewall while the communication via Cisco is down. Only those hosts which connected via Cisco are experiencing the problem. I can not say where the traceroute from AS/400 stucks (there are other people who maintain the machine and they never could catch the exact moment of outage).
To turn off CEF I treat as the last option actually and unfortunatelly there is no guarantee that software upgrade will help (we have 12.4.3a now).
So first of all I'm trying to understan WHY it happens because I can not see any systematics in the problem appearance. It can happen 3 times under 2 days and then dissapear for 1-2 months...

ASA 5510 and Windows Vista/7 VPN problems

Hi, I'm a programmer that's had to take over the sysadmin position (thank you economy) and our boss can't get access to the VPN with his new Windows 7 laptop. I've been banging my head trying to figure this out but I can't.
I think it gets past the phase 1 stuff, because windows stops the connection process when it hits "Authenticating username/password."
It works on our old XP systems and on OSX. It just doesn't seem to work on Windows 7.
Can anybody help? What do I have to add or change to get it to work?
Thanks so much in advance!

Hi,
I started again and used various combinations of encryption etc but they all come back the same so I'm at a loss.

WRV200 IPSEC VPN to a remote site with 2 different subnets

Hi,
My old WRV54G had no problem with this! I'm trying to connect an IPSEC tunnel back to a router at my main office, there are two Subnets there 192.168.0.0/24 and 10.171.131.0/24. In my old router I would set up two tunnels to the same gateway with different subnets and everything would work fine.
When I do this with the WRV200 both tunnels come up but in the view of the VPN status they both have the remote network listed as 192.168.0.0 /24 and I can't seem to get them both to work. If I delete the 192.168.0.0/24 tunnel (tunnel #A) and just use the tunnel#B I can connect to the 10 network.
Anyone been able to get this working?

Hi,
Ok, so the first thing you will have to think about is the encryption domain of the existing L2L VPN. Since your aim is to publish a Web server from another site through a L2L VPN connections you have to consider what the source addresses for the Web server connections can be?
It might be that you would need to have the source address for the L2L VPN in DC1 as "any" and naturally on DC2 the destination would be "any".
Though in that case it would probably cause problems if the Web server would need to use the DC2 Internet connections for something. This is because we would have now defined that traffic from the Web server to "any" destination IP address should be tunneled to the L2L VPN.
One other option might be that you actually configure DC1 site so that all incoming traffic from the Internet towards the 111.111.111.111 will have their source address translated to a single IP address (to be decided) before entering the L2L VPN. This would eliminate the need to use the "any" in the L2L VPN configurations because the Web server would see all connections come from a single IP address and therefore would not cause problems for the DC2 Web server IF it needs to access or be accessed through the local DC2 Internet connection.
Judging by your examples it would seem that you are using a 8.2 or older software level. Would you be willing to share some current configurations (with masked public IP addresses) or should I just give you some example configurations?
Most important ones would naturally be current NAT configurations and configuration related to the L2L VPN connection.

ACS/ASA authentication for vpn access vs. console management access

I have an ACS 4.2 Server and an ASA 5540. I have setup AnyConnect SSL VPN on the ASA and want to authenticate users using AAA tacacs+ authentication with the ACS and an external Windows AD database. I have done this successfully. I also want to use the ACS for authenticating SSH management sessions into the ASA. I have setup a group in AD and on the ACS called VPNUSERS and NETADMINS. The problem is, I want the VPN users to ONLY be able to authenticate for VPN but not have access to logging into the ASA CLI or ASDM. The NETADMINS should be able to do both. The question I have is how do I setup the VPNUSER group in ACS to have access to connect to the ASA for VPN but not for the management console? It seems that if they can authenticate for vpn, they can also ssh the firewall which is what I want to prevent.

Try using Network Access Restrictions (NAR)where you can restrict the administrative access on per device or on NDG basis.
By default user accounts from external database such as AD in ACS will get authenticated through telnet on network device or a AAA client which can be restricted by enabling NAR in ACS.
In your case it should be VPNUSERS group in ACS.

CIsco ASA 5505 and VPN licenses

Hi,
Cisco ASA 5505 comes with 10 VPN licenses in a standard configuration.
How those licenses are counted? Will I need a license per one IPSec SA?
If I have two site connected with LAN-to-LAN VPN with 10 subnets at one site, how many licenses will be taken? 10 - one per IPSec SA or just 1 - one per point-to-point VPN?
Thank you.
Regards,
Alex

Alex,
In an ASA 5505, it should say something like this...when you do sh ver.
VPN Peers : 25
It means that you can have so many peers connecting to the ASA. Its not per IPSec SA.
Its a per tunnel license.
Rate this, if it helps!
