Cisco VPN :: 1800 Site-to-Site VPN Tunnel Bandwidth For Voice Traffic
Jun 22, 2011
I have some challenges with a VPN config I recently setup for a client.I have at the HO the following:
- 1800 router
- Avaya phones and Gateway
- 1MB radio internet access
At the BO(branch office), i have:
- 871 Router
- Avaya phones
- 256k internet bandwidth
The only reason we setup the VPN in the first place was for the phones at the BO to be able to connect to the gateway at the HO and also able to make calls and receive calls as if the phones were at the HO.The phones at the BO successfully register to the HO, but are unable to recieve calls and dial out. Everytime I try to make a call, the phone displays a "connecting..." message. [code]

I want to configure QoS for voice traffic over a site-to-site VPN tunnel. I have a Cisco 851 router on the branch end and a Cisco 1800 router at the HQ. The setup is an Avaya Gateway located at the HQ and the idea is that the phones at the branch office are connected over the VPN tunnel to the gateway at the HQ.
I have a 1MB internet link at the HQ from a service provider and 256kbps internet link (from a different service provider) at the branch office. The branch office has just 3 users.

At the main site, I have 3 5508 WLCs each part of a mobility group (wlcMain-MG). In NCS, under "System/Mobility Groups" for each controller, I see each controller listed as "local" with the other Controllers listed with the group name "wlcMain-MG". None of the SSIDs are "anchored".
I have a new site with a 2500 series WLC that I would like to push out 2 SSIDs. This site contains two customers. One customer is the Main customer with the second customer leasing space.
I have the Cust2 WLAN at the remote site set to have traffic egress out of a local interface on the 2500 WLC (this traffic is then tunnelled back to their Main location via an ASA which houses the DHCP scope for that vlan). I can connect to this SSID, obtain an IP Address off the ASA and am tunnelling without issue.
For the Cust1 WLAN at the remote site, I would like to broadcast an SSID from the Main location on those same APs which are registered to the 2500. It is my understanding, that I anchor the SSID at the Main site and identically configure the SSID at the remote site. This will allow the end user to authenticate to the RADIUS server at the Main site and be placed upon the correct vlan (we are using DOT1x and dynamic vlans).
For my test, I am starting simple. I have created a test WLAN with no authentication. At the main site, on 5508 WLC3, I have created the test WLAN, and placed the interface into a low security vlan (call it VLAN-low). I have anchored this test WLAN to that controller. At the remote site, I have created the same WLAN (but placed it into the management interface for now - the VLAN-low does not exist at the remote site) and configured that WLAN to anchor back to the WLC3 at the main site. I am unable to obtain an IP address from the remote site. I have placed the remote site WLC in the wlcMain-MG as well. How close does the code need to be on the controllers - the 5508s are at 7.0.116.0 and the 2500 is at 7.0.220.0? What could I be missing?

I do have a 5505 up and running, and passing data... url...Now I am trying to get a IPSEC VPN tunnel working.I actually have it up (IKE phase 1 & 2 both passed), but it is not sending/receiving data through the tunnel.
The networks concerned: name 10.0.0.0 Eventual (HQ Site behind Firewall)name 1.1.1.0 CFS (Public Network Gateway for Palo Alto Firewall - Firewall IP: 1.1.1.1)name 2.2.2.0 T1 (Remote site - Outside interface of 5505: 2.2.2.2)name 10.209.0.0 Local (Remote Network - internal interface of 5505: 10.20 9. 0.3) On a ping to the HQ network from behind the ASA, I get port map translation creation failed for icmp src inside:10.209.0.9 dst inside:10.0.0.33 (type 8, code 0)
I am suspecting that there is a NAT error and/or a lack of a static route for the rest of the 10.0.0.0 traffic, and that I may have to exempt/route the traffic for the HQ network (10.0.0.0), but I haven't been able to get the correct entries to make it work. [code]

I have ASA 5505, i configured site to site vpn between central site and remote site and is working. Now the problem is we use remote site for troubleshooting purpose, so we need to create a tunnel from remote site to central site. I need to configure such a way that remote site can craete a tunnel to central site, but central site not able to create a tunnel, it just respond to remote site.

I have cisco pix connected at the edge of my GPRS network. Inside is the GPRS core network and outside is the ISP.On cisco pix, i have site to site IPSec configured between my inside GPRS network and Blackberry servers. for blackberry services.Using the ASDM I can see the total number of packets in and out on this site to site IPSec, but if I want to measure the trand of the bandwidth utilisation over this IPSec, per sec, then how can I do this? I have PRTG traffic monitoring, through which I did try, several MIB (listed below) but still not able to find the correct way. how can I get the measurement for the IPSec from cisco pix?

I have a ASA 5510 that has multiple site to site VPNs. I need to create an additiona site to site VPN but only allow 1 host to access and traverse the tunnel. The network is on a 192.168.5.x but the host that will need to access this tunnel needs to be on a 172.16.33.x network. I dont want any other traffic allowed to access or traverse the VPN tunnel for this host. How can I set this up?

As you can see i have problems with connecting 2 SRP521W together for an VPN tunnel. I tried as much as I can but now i dont know what to do or how and where is the mistake? the connection between these two devices was there last week, after weekend (nothing changed in configs) the connection suddenly was interrupted, without any reason or warning. another day it worked again and 20 mins later connection was dead again...and now it wont establish at all.. here are some screenshots from the vpnconfigs of my devices. one has a static IP the otherone uses FQDN. These are the IKE policies: Here the IPsec Policies: and the GRE policies:

How can I NAT the same set of four hosts and give them access to two different networks across an IPSEC site-to-site VPN tunnel? I'm using an ASA5520 running 8.04.
I have four hosts say: 10.240.1.1-10.240.1.4
They need access to two different networks:
205.100.150.0
140.175.200.0
I woud like to NAT them as something like:
7.5.210.1
7.5.210.2
7.5.210.3
7.5.210.4

Remote VPN is Policy 20

We have configured a site to site tunnel from our ASA to another organizations Cisco 3030. It appears to have just one way initiation. We can do a ping to a device on the remote site and it will ping just fine. however, when the tunnel needs to be initiated from the remote site, it will not work until we have initiated the tunnel and then everything works.
I continue to see Error processing payload: Payload ID: 1 errors on the ASDM logs.It appears that all the configuration is in place because we can in fact establish the IPSec tunnel unidirectional. And once established, traffic can flow bidirectional.

I have weird problem with a Site to site VPN tunnel from a Cisco ASA 5505 to an Clavister Firewall.When I restart the Cisco ASA 5505 the tunnel is up and down,up, down, down, and I get all strange messages when I see if the tunnel is up or down with the syntax: [code]
After a while like 5-10 min the vpn site to site tunnel is up and here is the strange thing happening I have all accesslists and tunnel accesslists right I can only access one remote network (Main site Clavister Firewall) trought the vpn tunnel behind the Cisco ASA 5505, and I have 5 more remote networks that I want to access but only one remote network is working trought the vpn tunnel behind the Cisco ASA. I see that when I do this syntax in ASA: show crypto ipsec sa.They had a Clavister Firewall before on that site before and now they have a Cisco ASA 5505 and all the rules on the main site thats have the big Clavister Firewall is intact so the problems are in the Cisco ASA 5505. [code]
All these remote networks are at the Main Site Clavister Firewall.

We have approx 40 branch offices - all of which are connected to a single core site over VPN Tunnels using various gear. At one particular site, we are having issues with the tunnel dropping sporadically throughout the day - some days it happens 10 times, some days it happens none. This just randomly started happening two weeks ago, without any changes taking place. Since it started happening, I have upgraded the code to latest versions, but still the issue persists. This particular site has a 2901 and connects back to a 2951.
Below is the output from:

I have a situation where the site-to-site tunnel is already established using PPTP IPSec VPN with non Cisco Gateways terminating the link on each end. These non Cisco Gateways do not support L2TP tunneling, and there is no plan to change them.Beyond the Gateways on both ends, we have a Cisco 4500 series switch. We need to forward the 802.1q tagged VLANs between the two sites. Is it possible to use 802.1Q tunneling in this case, going via a PPTP tunnel ?
Cisco's setup uses dot1q-tunnel over a L2protocol-tunnel to preserve the original client VLAN tagging, so does this mean that the only option we have is to setup a L2TP tunnel at the Cisco device endpoints, and have that tunnel go through the existing PPTP tunnel (established between the 2 non Cisco VPN Gateways) ?

Remote-access users aren't able to reach our remote network through a site-to-site VPN tunnel between two ASA 5505's.
I've seen several threads about that here, I've run through the walkthrough at [URL] I've taken a stab at setting split tunnelling and nat exemption, but it seems I'm still missing something. Remote-access users can reach the main site, but not the remote site.
Remote-access (vpn-houston) uses 192.168.69.0/24.
The main site (houston) uses 10.0.0.0/24
The remote site (lugoff) uses 10.0.1.0/24

Is that possible with asa 5505 and do i need some special IOS bundle for that? May i use vpn wizard for that or do i need to go through cli since remote access vpn is setup using wizard.

I have a site to site VPN tunnel configured between a rv220w and rv180. Everything works fine going from site to site on LAN connections. I'm now trying to tie in the remote site wireless (rv220w side) by pointing radius to my ACS server which is on the other side of the site-to-site tunnel but it seems as though it doesnt route across the site to site tunnel. If i put a radius server on the local lan on the remote site that authentication works fine. I have confirmed there are no ACL problems. the RV220W capable of using a radius server across the vpn tunnel?

i have a client who needs to establish a VPN tunnel from his satellite office (Site A) to his corporate office (Site Z). His satellite office will have a single PC sitting behind the ASA. In addition, he needs to be able to VPN from his home (Site H) to Site A to access his PC.The first question I have is about the ASA 5505 and the various licensing options. I want to ensure that an ASA5505-BUN-K9 will be able to establish the site-to-site tunnel as well as allow him to use either the IPsec or SSL VPN client to connect from Site H to Site A. Secondly, I would like to verify that no special routing or configuration would need to take place in order to allow traffic not destined for Site Z (i.e., general web browsing or other traffic to any resource that is not part of the Site Z network) to go out his outside interface without specifically traversing the VPN tunnel (split tunneling?)Finally, if the client were to establish a VPN session from Site H to Site A, would that allow for him to connect directly into resources at Site Z without any special firewall security rules? Since the VPN session would come in on the outside interface, and the tunnel back to Site Z goes out on the same interface, would this constitute a split horizon scenario that would call for a more complex config, or will the ASA handle that automatically without issue?

I have a site to site tunnel (bidirectional) configured between two ASA 5510's (head office and remote office) running 8.2.2. I'm trying to upgrade one end (head office) of the tunnel to 8.3.2 but when I do that, traffic from the remote office to the head office isn't transported. Traffic from the head office to the remote office is still fine (remote desktop sessions, etc).
A quick comparison of the 8.2.2 config and the 8.3.2 config on the head office ASA look identical in terms of the crypto/site-to-site commands.Is there any Cisco guide created yet for creating site/site tunnels under 8.3.2? I'm able to upgrade both ASA at the same time if that's determined to be a prerequisite.

Datacenter = 10.12.0.0
Site to Site Tunnels:
Headquarters ---> Datacenter
Datacenter ---> Client X
I want to ability for computers in the Headquarters subnet to access the Client X subnet.I have tried setting up a static route to push all traffic destin for 172.16.0.0 to the datacenter, but was unsuccessful. how I can route all 172.16.0.0 through the tunnel.I have tried ading a static route on my ASA but without success.

I'm currently trying to configure a Site to Site tunnel between an IOS Router and an ASA 5505 running 9.1
When the private subnet of the IOS Router was 10.0.0.0/24 and the private subnet of the ASA was 172.16.1.0/24, it connected fine.
I'm now trying to set it up where both private networks are 10.0.0.0/24, and created network objects, edited the ACL for interesting traffic, and created the twice NAT translation rule, but the tunnels aren't coming up.
There is the IOS Router(R1) and the ASA(F2). In between them is one Internet posing router that is just set up to allow both sides to reach their WAN addresses.
R1 and F2 have private network (10.0.0.0/24) and need to communicate. Twice NAT can be done all on the ASA to allow this, but I must be doing something wrong. The way I understand it, is that the R1 should see the traffic coming from 10.51.0.0/24 and sending to that traffic. The ASA will take that traffic, and the inside network should see it come inbound as 10.50.0.0/24. So the F2 private network communicates with 10.50.0.0/24 and R1 private network sends traffic to 10.51.0.0/24.
I turned on "Debug crypto ipsec" and "debug crypto isakmp" but no output is showing up or giving any hint that it is trying to establish anything.
