Cisco VPN :: 5505 Create VPN Tunnel Between Two Offices
May 27, 2011
I have two cisco ASA 5505 devices and two cisco switches plugged to ASAs in each office. I need to create a VPN tunnel between two offices.
-Network behind the ASA1 in office1 is 192.168.1.0/24 with DHCP server – 192.168.1.10
-Networks behind the ASA2 in office2 are 192.168.5.0/25; 192.168.5.128/26 and 192.168.5.192/26
All computers in office2 need to get IPs from DHCP server 192.168.1.10. I have switch in office2 with 3 VLANS and I can assign computers from different subnets to different VLANs.How can I archive this goal? Should I assign 3 IPs for ASA2 inside interface (192.168.5.1, ...5.129, ...5.193) as a default gateways for each subnet? Should I put dhcp helper address 192.168.1.10 on the switch for each VLAN?

I am trying to configure access to several remote offices for users who VPN into our main datacenter. The datacenter has a 5520, and the branches are connected through IPSec L2L VPNs. Branches all have 5505 or 5510's. Remote users use IPSec via the Cisco remote Client. Remote access into our data center works, and the L2L VPNs are perfect...just now that i need remote users to access the branches after Remote access VPNing (for support) i cant get that part to work.

We currently run dual ASA 5510's in A/S config on our main campus. We would like to create a VPN tunnel to a branch campus. Trying to decide between a 5505/5510/5512x, We would like to extend many of the capabilities of our network to the branch campus which will be 20-50 users on a 50mb/10mb internet connection.
Domain login
System Center workstation management
Cisco WCS
Shoretel voip
(Cisco NAC?)
Several different VLANs for wireless guest, student traffic, staff traffic, voip traffic, etc. Which device would be best and should we get the security plus license with it?

I'm currently setting up two VPN 3000 Concentrators at two different sites to create a IPsec LAN-to-LAN Tunnel. I have gone through all the basic configuration guides on the CISCO site, but a LAN-to-LAN session is never created. I have enabled the logs on the Concentrator and it displays no errors at all - it appears the Concentrator is not even trying to establish a IPsec LAN-to-LAN Tunnel.After running through the standard setup provided by CISCO, is there anything I need to do to make the Concentrator try to create a Tunnel, or should this be automatic once all settings are in place?

Im able to create a gateway tunnel with two rv042 routers in different locations ( i can see the tunnel connected in the router) but the quick vpn utility is not working , i also tried to use the pptp as server as an alternative( im able to connect using windows connection to the pptp server but whenever I browse any of the four ip's allowed for the pptp server \10.0.0.200-204 it takes me to the documents of the local computer....I attached the configuration for one of the routers it is the same as the other end , just the information is flipped.

I have a production ASA 5505 that is working perfectly. I wanted to take a spare ASA 5505 and copy the running config to it so that I would have a backup unit that could be swapped out if the production unit went down.
Both units have security plus and running 8.2(1). The only difference is that the production ASA has 512MB of RAM while the backup ASA has 256MB. Also the backup has anyconnect and the production unit does not.
I copied the running-config to my tftp server and then copied the running config from my tftp server to the backup ASA as startup-config. After reload the device booted with an identical configuration to my production ASA, but after swapping out the units to test it, I have no access to the WAN or DMZ from my LAN. Swapping back to the production unit and all works as it should.
I printed out the running config from both devices and compared them line by line. They are identical except for the anyconnect line on the backup ASAs config file.

I have a customer an exisiting 5505 which connects to multiple sites for a site-to-site VPN. This firewall was not installed by myself originally I have just been asked to take a look now.The situation is that we now need to edit one of the existing site-to-site VPNs to include the remote sites expanded network. I have tried doing this through the ASDM and have found that I cannot add new network objects. I have tried creating a new network object group and then added the new networks from there but I am completely unable to add the new objects.I believe a picture tells a thousand words in this case so I have attached some images which show the problem. I have also tried going through the VPN wizard, this also does not allow me to add new network objects.

trying to configure our ASA 5505 (hence my request for the ASDM). However, I can go CLI if push comes to shove.
What I'm trying to do is allow a range of IP addresses on the inside interface (those which the DHCP server is doling out IPs which are XXX.X.XXX.14-140) to access email only (which is hosted offsite). They still need to access the file servers which are on the inside but nothing should be going out to the internet other than email.
I believe I have to create a Network Object which contains the IP range I wish to restrict. I can see where I add the Network Object but I don't know what the syntax should be to specify the address range.
I'm also not sure what the sequence of the ACLs should be and whether or not I can keep the default Access Rules in place. There are the two implicit rules: 1) Permit any traffic out to less secure networks 2) Deny any traffic to anywhere (which is superceded by rule 1, yes?)
To create an Access Rule like the one I desire, do I need to move the two existing rules down the list so that the new one will supercede both implicit rules?

I just upgraded my firewall to ASA 5505. Now, my original static ip address cofiguration is gone. Apperantly, Cisco went away from static ip address to something like nat (inside,outside) dynamic interface. how to create a static ip address under version 8.4? By the way, I am sharing what my configuration used to look before upgrading.
!
hostname cisco-asa
domain-name default.domain.invalid
names
!
interface Vlan1
nameif inside
security-level 100

I have a newly aquired asa 5505 that I just set up to the bare minimum configurations. I followed a cisco paper on how to create a "remote access vpn" setup for ipsec. I can sucessfully connect and establish a VPN, but when I try to access an inside resource from the vpn address, the asa blocks it.
Specific error is: Code...

I'm trying via the ASDM to port forward http connections to a DVR for the purpose of viewing IP cams.I've tried via ASDM to create a public server but I'm not allowed to use my public IP address for the public Interface.I have only one public IP address available.Is there any way round this ? I would also like to know how I can enable NAT with PAT.I've tried setting the outside Interface for use with PAT but It keeps reverting to the setting for a range of external addresses.I'm not really used to the ASA cli yet , I'm getting there.If there's a workaround via the CLI , I'll take that route.

Just started using our ASA 5505 v8.2 (1) Trying to configure the ASA appliance to allow access into an internal resource (i.e want to be able to RDP into a system behind the ASA from the internet).I have used a static NAT:
static (inside,outside) 100.100.100.2 192.168.1.28 netmask 255.255.255.255
access-list OUTSIDE extended permit tcp any host 100.100.100.2 eq 3389
When I view the logs it is reporting the following:Inbound TCP connection denied from 206.100.100.1 (external IP) to 100.100.100.2 /3389 flags SYN on interface outside.Been pulling my hair out with this one as I believe I have everything configured correctly.

i got a person who connect with vpn on a adsl connection to the corporate network.this person is using cisco ip phone on his remote location and i did configure the ASA 5505 to priorize voice over data.i still get voice skips when the remote pc is uploading data to the corporate network...what i've done is :
1.with asdm i did create 2 priority queues one for inside (queue limit 2048 trans ring limit 512) and outside (queue limit 2048 trans limit 256)
2. with the service policy wizard i did create a global service policy (all interface) and a traffic class for dscp 46 ef and on qos tab i did check the "enable priority for this flow"...
3. When using the phone, i clearly see that packets are growing on the LLQ queue (show priority-queue statistics)
4. i still get voice skips when uploading data to the corporate network... upload bandwidth is about 800k for upload the pc and the phone is on the same subnet

I finally got the VPN tunnel between 2 asa 5505's up and running, but I have some error codes on the initiator side that I can not figure out. [code]I have looked at the Crypto transforms on both sides, and they match just fine as far has the DH ID code, Group Number and the encryption. The remote side however, does not have any of there errors.
Is this something that I have skipped over, or missed that I should be looking for? The IP address that is listed above is not in my static addresses, not sure where theose are coming from. I believe that they are outside public IP's.

We're setting up a site to site VPN with a customer. Our side is a Cisco sa520 and there side is a Checkpoint. The tunnel is up, we've verified phase 1 and 2 are good. The issue is passing traffic across the tunnel, our LAN ip address are private addresses 10.10.1.0/24 but the customer states that we need to have a public IP address for our LAN in order to access there server on there LAN. So looking through all the forums, I see that you can NAT before crossing the VPN tunnel, but our issue is that our site only has 6 IP addresses assigned to it and those are the Comcast router, the WAN side of the SA520 firewall.
So we were wondering was there a way that we can either use the WAN interface on the SA520 or use another available of the 6 that were assigned to NAT and pass traffic across the tunnel. Sounds confusing? sorry but it is, rarely do I have a customer say I have to have a public IP for my side of the LAN. Now I also say this is a SA520 firewall, but if it's not possible to do with that is there a way were could with an ASA5505?

I have an interesting SVPN challenge that I'm asking the subject experts here to assist me in solving.A customer in Domain A wants to transmit data to Domain B. The customers have agreed to establishing a secure vpn connection from Domain A to Domain B to transmit real time data. The challenge comes from sending unencrypted data from nodeA to nodeB & nodeC withing an encrypted VPN tunned to node d.The challenge is sending non-encrypted data from NodeA to NodeB where an encrypted VPN session is active. Every time I attempt to configure the interface (AppC) the VPN session is terminated, and the interface can no longer "see" nodeD via IP mapping. An engineer recommended adding a second NIC card to NodeB thereby permitting control of the AppC even when the VPN is up and running.Can I send live non-encrypted data to NodeB data buffer, while AppC sends data to NodeD in a VPN tunnel ?

I have set up two ASA 5505's (lets call them ASA1 and ASA2) with site to site VPN configuration and i've encountered two problems with my setup.ASA1 has IP 192.168.1.254 on the inside interface and is connects ASA2. It's also an Easy VPN Server for external users to connect through Easy VPN Client.ASA2 has IP 192.168.11.1 on the inside interface and connects to ASA1 Problem #1 None of the ASA's can ping eachothers inside LAN IP address. Computers behind the ASA's are unable to ping the remote ASA's inside IP address. My guess is that this has to do with either NAT or built in security.Problem #2. The Easy VPN clients which connects to ASA1 are unable to access the LAN behind ASA2.

I´m getting a dynamic public IP from my provider and what I´m trying to do is to establish a remote vpn tunnnel using IPSec which I achieve but every time the sessions resets or the ASA 5505 resets I get a new public IP and I need to put the new IP on the remote client so I can establish the vpn... How can I establish an ipsec vpn using DNS? For this scenario the remote vpn client is a vpn phone but it could be for any vpn client.

I have a site to site IPSec tunnel setup and operational but periodically the remote site goes down, because of a somewhat reliable internet connection. The only way to get the tunnel to re-establish is to go to the remote site and simply issue a ping from a workstation on the remote network. We were having this same issue with a Cisco PIX 506E but decided to upgrade the hardware and see if that resolve the issue. It ran for well over a year and our assumtions was that the issue was resolved. I was looking in the direction of the security-association lifetime but if we power cycle the unit, I would expect that it would kill the SA but even after power cycling, the VPN does not come up automatically.

I've a asa 5510 on the main site and different ASA 5505 on secundary sites for VPN tunneling between the sites. The problem is that the tunnels are acomplished but no traffic is going over them. What am i doing wrong? For the moment there is a ASA 5505 on the main site managing the tunnels but I want the 5510 to take over the job.
