Cisco VPN :: C2811 Client Vpn And Site On Same Router
Mar 20, 2011
I have an office c2811 and it has three Ethernet interfaces(two onboard and one expansion). Faste0/0 is on one isp and faste0/1 is on another. The third is private. I have multiple site ipsec vpn’s terminating on faste0/0. I had a client ipsec vpn on faste0/1. One of the site vpn’s on faste0/0 terminates at a collocation site. Both the site vpn and client vpn need access to the same collocation. When I connect via client vpn, I cannot ping/access collocation subnet. I suspect this is because I have a site vpn already terminating to the collocation. Can I have a site and client ipsec vpn on the same router terminating to same place and still work?

I setup RA-VPN under local asa 5510 IP pool (192.168.127.0/24) and all was working fine. I got internet and local network access.
Then i have 5 site to site VPN working fine but when im traying to access to those L2L VPNs from the remote acces client im not able to do that. So after that i decided to obtain IP addresses from my DHCP server so i can obtain IPs from my local network (172.17.16.0/16) and then access normally to the VPN site to site. But the surprise was that the VPN cisco client is getting local IP address (172.17.16.222) perfectly but im not able to access even to my local network.
I have the same-security-traffic permit inter-interface same-security-traffic permit intra-interface enable.

We have a scenario where the Cisco ASA 5505 will be one end of a site-to-site VPN. The same ASA 5505 also allows Client VPN connection. The question is around IP pooling. If I assign a pool of IP's (192.168.1.20 - 192.168.1.30) for Client VPN connections - do I need to be sure that those same IP's are not used on the other side of site-to-site VPN ?
There could be PC's/Servers running 192.168.1.0/24 on the other side of site-to-site VPN. Would this cause an address conflict ?

A user with Easy VPN client connects to a 876 ISR (router A). This router also has a site-to-site VPN to another 876 ISR (router B). What I want to achieve is that the user dials in to router A and can access the network on the remote end of the site-to-site tunnel (router B) In diagram:
user (192.168.18.x) - Easy VPN - Router A (192.168.16.x) - sitetosite - Router B (192.168.17.x)
I have added routes in router B to the 192.168.18.x network with router A as next hop, but I can't reach the other segment.

I am considering to buy two RV180Ws and place them on two separate locations. But before buying I would like to make sure that the units meets my requirements. Lets call the locations A and B. I would like to connect location A with full network access to location B. But at the same time I would like to have that location B also gets full access to the network at location A.Besides this I would like to be able to connect to one of the networks from remote with my laptop.Preferably all connections should be made using IPSEC and not PPTP.I would like to know if it is possible to make such a configuration, and eventually if there is a smarter way to do e.g. only letting clients connect to location A or B and granting them access to all ressources at both location A and B from there.

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?

How can I set up a Cisco 831 router (branch location) so that it will accept inbound VPN Client connections and initiate a site-to-site IPSec tunnel to our hub location that uses a VPN 3005 Concentrator? I could get the tunnel to work by configuring it in a dynamic crypto map but interesting traffic on the Cisco 831 side would not bring the tunnel up.

We have a Cisco ASA 5505 at our CORP location, which I have configured the Site2Site VPN to our COLO with a Juniper SRX220h, the site to site works fine, but when users access the Cisco VPN client from home, they cant ping or SSH through the Site2Site. Contacted JTAC and they said its not on their end, so I tried to contact Cisco TAC, no support. So here I am today, after for the 3 days (including Friday last week) of searching the Internet for over 6hrs a day, and trying different examples of other users. The VPN client show the secured route to 10.1.0.0. [code]

i have an ASA 5520 Version 8.0(2), i configured the VPN site to site and works fine, in the other apliance i configured the VPN Client for remote users, and works fine, but i try to cofigure the 2 VPNs on ASA 5520 on the same outside interface and i have the line "crypto map outside_map interface outside (for VPN client)", but when I configure the "crypto map VPNL2L interface outside, it overwrites the command", and therefore I can only have one connection.

recently we had some performance issues with C2811 which caused us to do some lab testing. For testing we used also C1812. The results were quite surprising for us, as the C1812 appeared to be more efficient than C2811. Below you can see the lab scenario and results.
1. Why C2811 is performing worse than C1812?
2. Is there any official Cisco reference stating what are the max VPN throughputs of certain platforms/models? (we consider migration to C2900 platform and would like to choose the right model)

as presented on the small diag:
All routers had enabled onboard hw VPN modules and SEC/K9 IOS ver. Configuration was very simple and beside encryption there were also GRE tunnels configured and EIGRP process for routing between "remote LANs". Part of conf responsible for encryption:

Required by regulations to implement CoPP on our routers, I installed the following configuration on a C2811 router pair with integrated DSU/CSU cards connecting a point T1. STAC compression(software) is configured on the serial interfaces and the link is often congested.
[code]...
This configuration severely degraded the IP traffic flow and I had to remove it. Not having any practical experince with CoPP.

Need configuring Client to Site IP Sec VPN with Hairpin on Cisco ASA5510 - 8.2(1).
The following is the Layout:
There are two Leased Lines for Internet access - 1.1.1.1 & 2.2.2.2, the latter being the Standard Default route, the former one is for backup.
I have been able to configure Client to Site IP Sec VPN
1) With access from Outside to only the Internal Network (172.16.0.0/24) behind the asa
2) With Split tunnel with simultaneous assess to internal LAN and Outside Internet.
But I have not been able to make traditional Hairpin model work in this scenario.
Following is the Running-Cong with Normal Client to Site IP Sec VPN configured with No internal Access:
LIMITATION: Can't Boot into any other ios image for some unavoidable reason, must use 8.2(1)
running-conf --- Working normal Client to Site VPN without internet access/split tunnel:
ASA Version 8.2(1)
!
hostname ciscoasa
[ code ].......
Neither Adding dynamic NAT for 192.168.150.0/24 on outside interface works, nor does the sysopt connection permit-vpn works
What needs to be done here, to hairpin all the traffic to internet coming from VPN Clients. That is I need clients connected via VPN tunnel, when connected to internet, should have their IP's Nattered against the internet2-outside interface address 2.2.2.2, as it happens for the Campus Clients (172.16.0.0/16).

Is there any detailed documentation on the Site Survey Client mode on the AP 1200?When using this mode I cannot see any indication that it has associated withthe root AP. I would like to be able to pass traffic from the ethernet port to the root AP VIA the AP in client mode. The Ap in client mode shows the radio in blocking when in client mode, is this normal? Is there a way to manually change this to forwarding mode?

Installed 4 AP541N units in a client site and they've now come back with reports of issues with the setup. I went out there today to take a look and the issue is primarily that randomly during the day, clients will loose access to DHCP. The client authenticates fine (we see success logs in the Windows 2008 RADIUS event logs) but doesn't manage to get an ip address.To sum up the things with the current setup:
- Running version 2.0 Code on the AP541N's.
- Using Windows 2008 for NPS (RADIUS) and DHCP.
- Cisco Catalyst Switching in the back end.
Things tend to work fine in the morning. It's as the site hits midday that we start seeing issues.In looking at the issue I've come across a number of posts in regards to issues with DHCP and these units. One item that was suggested to switch off Mutlicast / Broadcast limiting on the Advanced Settings. What's weird with this is that if I do disable this option, RADIUS authentication stops working entirely. Switch limiting back on and RADIUS works again. I've confirmed this with Network Monitor running on the RADIUS Server.

I currently have a Cisco ACS 3415 appliance with 5.4. Coming from the ACS 4.2 world, I'm have a bit of a struggle creating the following and I was hoping if I could be shown clear steps I can duplicate the rest.
I want to creat a group ie: AIRTEMP with access time from 7:00am to 5:00pm and add 2 users to the group.
Users access our site using a vpn client connecting to a ASA5550. The ASA and the ACS already communicate with each other.
The ACS 5.4 user guide has me bouncing all over different page.

I need to configure a site-to-site VPN using a Cisco 881 router on my end and connecting to an ASA5510 on my suppliers end.Our supplier has configured their end and I do not have access to their configuration.
They told us we have to NAT all inside address' to a single address (192.168.89.1) as this is the only one they will let through their firewall/tunnel.I know how to set up the VPN but not too sure how to set up the NAT part.
My sanatized config is attached. The code I am using to NAT my inside network to the single address 192.168.89.1, and send all traffic accross the VPN tunnel as this address is correct? With the router running this config the VPN tunnel does not connect.

I have an issue with 2 site to site VPN tunnels from a RV042G router. The issue is for both VPN tunnels is that in the logs, it is showing that when the RV042G router is trying to establish the tunnel, it is getting a response from the remote gateway internal address and not the Public address of the remote gateways. On the remote gateways I have other site to site VPN's terminating fine and the tunnels are passing traffic. I only have an issue with the RV042. On the VPN Tunnel page it shows for both tunnels waiting for connection. This is an output from the log of the RV042G

I am trying to create a site to site VPN using a cisco 2901 and Linksys router.I have the VPN configured and connected and I can ping gateway to gateway. However, from the Cisco I can't ping any of the devices beyond the gateway.Example, from the cisco I can ping 192.168.5.254 (gateway IP address) source gig 0/1 and it works great.
However if I ping from the cisco 192.168.5.50 (end user PC) source gig 0/1 it doesn't work.I have created a client VPN and that works perfectly.Below is my config.

I'm able to ping from Site B (192.168.2.xxx) to Site A, however I can't communicate from Site A back to Site B.how I could go about troubleshooting this? I've been scouring the internet for 3 days trying to get to the bottom of this with no luck.

I have recently bought two CISCO routers RV220W for our main and brach office mainly for VPN tunneling. I didnt know they are routers only not modems. so I have set it up using BT 2wire Router as modem only.
I have successfuly setup the routers and manage to establish the VPN tunneling between two routers. AS bt doesnt give static WAN IP address so I have used Dyndns which works fine. although I have 5 static ip address which cannot be used for WAN unless i cahnge to one IP address even then BT tech said it will not work.
when I created the tunnel i could ping both servers with their IP only not with the names. I can ping them fine locally. I could also see the network from branch office to main office but not from main office to branch office. today when I restarted the server I cannot ping both server i mean vice versa but VPN tunnel is established. now I cannot see the network from branch office to main office as well.
Both sites running windows server 2008 standard. main office server has 6 NIC cards two wwith public and three with private ip addresses, its also runing Terminal server, exchange, file etc. the branch office has two NIC card one with private and one with public ip. Intially I could establish the VPN tunnel as the network range was same on both sites so I changed one in th e10.0.0.0 range other in 192.168.1.0 range and VPN tunnel was established straightaway.
As soon as the VPN tunnel was created I manage to creat an external trust without any problems and both servers are added in each other forward zones as name servers.
in the main office the fues went off and I had to re-start the router and now the VPN tunnel is not establishing, mainly the error is ISAKMP-SA Expired I will paste the log of both routers below
1. How to Clear Old or Existing Security Associations (Tunnels) on RV220W
2. how to fix the problem where I can ping the server with their IP as well as domain names ?
3. how to set it up so that both sides can see the network resources as well as access it ?
4. how to set it up so if the staff in branch office wants to log on the domain in main office he can simply do it as he does it in his office.
