Cisco VPN :: ASA5505 Configuration Not Working
Mar 8, 2011
I would like to configure a cisco ASA5505 IPSEC VPN. I used the wizard and tried to connect to the outside .. does not work .. The network is configured in this manner: - ADSL router with public address and internal address 192.168.2.1 -> firewall interface inside and outside 192.168.2.2 192.168.3.1 (my network is 192.168.3.0). I used a VPN to the pools ranging from 192.168.4.1 to 192.168.4.100.
INTERNET ----- ROUTER ------ ASA5505 -------LAN
What should I change? there could be problems between the router and firewall?

Our client has a vendor who needs to establish a VPN tunnel to their own router which sits behind our Firewall.
VPN Concentrator (Vendor) <------> ASA5505 Client (7.2) <-------> 3750 Switch <-------> VPN ASA outside Interface - 208.64.1x.x4 DG - 208.64.1x.x3
ASA Inside Interface - 172.20.58.13/30
3750 Switch Interface Connected to ASA - 172.20.58.14/30 and DG - 172.20.58.13
3750 Switch Interface connected to VPN router - 172.20.58.21
VPN Router Interface connected to the 3750 - 172.20.58.22/30 DG - 172.20.58.21
I have also attached a Visio for this and the running configuration from the ASA and 3750. We don't have access to the TNS VPN router. Our responsibility is to just to make sure the tunnel comes up.
1) Create a static NAT on the ASA for Public to Private IP of the VPN router
Public - 208.64.1x.x5 / 28
Private - 172.20.58.21 / 30
Will the ASA automatically ARP for this address or do i have to configure another interface on the ASA with this public IP?
2) What would the access list look like on the ASA?
3) The client gave us some config to copy the stuff on the ASA so that they can create the tunnel but i couldn't put those commands in the ASA. How would this be applied and on what interface?
Firewall Access: The following information pertains to access between the VPN router and the
VPN concentrator. If a firewall/router is present in front of the VPN the following services need to be
allowed:
permit esp host 208.224.x.x any
permit gre host 208.224.x.x any
permit udp host 208.224.x.x any eq isakmp
permit udp host 208.224.x.x any eq non500-isakmp(code )

We have had an ASA5505 for close to two years. About a year ago, we added a second ISP ("BOB") which became our primary and our old one (SBC) became our backup. I successfully modified the config for this and it's been working well.
Now we're changing our primary ISP to Comcast and getting rid of BOB, so right now we actually have 3 ISPs coming into our building.
I removed the BOB interface and routes, then added an interface for Comcast using an IP address from the range they provided as well as a static route to the gateway they provided - everything is analagous to the previous interfaces and routes, but it doesn't work. If I physically disconnect the Ethernet cable going to the Comcast cable modem, then the ASA does fail back to the SBC interface as expected. If I put the BOB interface & route back in there, it works again through BOB.
If I connect a PC to the Comcast cable modem and use an IP/Gateway they provided, the Internet connection *does* work. Using this same exact IP info in the ASA doesn't work.
Is there some other configuration item besides interfaces and static routes that I should be modifying? Is there some way I can dig deeper into the ASA to see exactly what is failing?

We have an ASA5505 that we need to enable hairpinning on.... In the old firmware versions, we used to be able to configure a public to private static mapping along with hairpinning by using
static (inside,outside) outside_ip inside_ip netmask 255.255.255.255
static (inside,inside) outside_ip inside_ip netmask 255.255.255.255
In 8.4, if I use object nat, the hairpin functionality works perfectly,
object network obj-insideip
nat (inside,inside) static publicip
however, since object nat only allows a single nat statement, I was attempting to use a twice nat to enable the hairpin functionality, but have been unsuccessful in coming up with the right combination of parameters for the functionality.
nat (inside,inside) source static private_object public_object destination static public_object private_object
allows hairpinning to successully work from the same machine. Meaning on any given host, I can ping itself using the private or public ip, but I can't get the right combination for hairpinning from any private host to another private host via the public ip. Other combinations have yielded icmp responses, however, they specify the private IP as the source of the reply instead of the public ip.

I teach in a High School and we've got about a 300 node MS Windows Network. Two MS2003 File Servers act as my DNS/WINS/DHCP servers. We have been using a WATCHGUARD FIREBOX III to act as the router/gateway between the outside external address and my internal (10.0.0.1) gateway address. All p.c's inside the network are routed to one of the Servers (10.0.0.2 or 10.0.0.4) for DNS/WINS/DHCP addressing. The servers point to 10.0.0.1 for gateway.
We are trying to replace the Watchguard Firebox with a CISCO ASA 5505 (eventually we'd like to implement VPN). When I connect the CISCO ASA, I get no internet passthrough at all.

I installed on 2 different PCs (Win7 64-bit) the Cisco VPN Client 5.0.07 with the same VPN profile for 2 different users. We use an ASA5505 (8.0(5) sec plus license) as the VPN end point for the clients. The VPN Clients can connect simultaneously to the ASA, they receive the split tunnel infos but only ONE client can ping the internal network ip range. The other one has no access to the internal resources! When they separately try to connect, there is no problem. Each of them can reach the internal net.On other 2 PCs (Win 7 32-bit) the clients have no problem reaching the internal net (simultaneously connect).

I am currently trying to configure an Easy VPN connection from an ASA 5505 to and ASA 5520. I have enabled split tunnelling and in the group policy defined the network to be tunneled but when I activate the VPN it tunnels everything from the host computer connected to the ASA 5505. I get no internet access. Have been trying to troubleshoot this for days.Hee are soe specifics, running version 8.2(5) on the 5505 and the 5520 and below is the local config on the 5505 for the Easy VPN:
vpnclient server **.***.***.**
vpnclient mode network-extension-mode
vpnclient nem-st-autoconnect
vpnclient vpngroup dbernstein-5505 password *****
vpnclient username dbernstein password *****
vpnclient ipsec-over-tcp port 10000
vpnclient enable
and the downloaded dynamic policy:
Current Server : 12.***.163.**
Primary DNS : ***.160.***.39
Default Domain : cisco.com
PFS Enabled : No
Secure Unit Authentication Enabled : No
User Authentication Enabled : No
Split Tunnel Networks : ***.160.***.0/255.255.255.0
Backup Servers : None

I am trying to get a Cisco ASA5505 to get onto the internet using PPPOE through a Netgear DG384 ADSL router. I have the Netgear in Modem only mode - if you put it in Router mode internet access works fine. When I change it to Modem mode, the error I get on the ASA is PADI timeout. Looking through the config I think I am missing a Global NAT??Also not 100% on the best way to set the IP - we have a static IP from the ISP. Do you set the interface to use DHCP and get this address or set it statically? Then do you put the setroute option or put in a static? [code]

There are two issues which are testing my resolve.
1) Bad Cryptochecksum Ignored error
2) Unable to boot to a save startup-config file.
I want to take the configuration from one ASA 5505 and move it to another ASA 5505. I copied the startup-config file from an ASA 5505 running asa821-k8.bin to an ASA running 8.222-k8 to flash using tftp. I set the boot config parameter on the new asa to flash:/startup-config which is the location of the startup file. If I use copy run start command, I over write the startup file. When I copy the startup configuration to the running configuration I get a Bad Cryptochecksum Ignored error and the startup file does not copy over to the running file. How can I resolve this issue?

I am using a Cisco E4200 router today but I am moving to a ASA5505. I have a device that sets up a VPN tunnel that I want to put in my DMZ. It's called the ATT Gateway. I have attached the diagram. When I use a Cisco E4200 all I do is put the outside private ip address of 192.168.0.99 of the ATT Gateway into the DMZ of the E4200 and the VPN tunnel of the ATT Gateway comes right up. I cannot configure the DMZ to do the same with the ASA. I also need to have the laptop behind the gateway access the printers in the inside network.

Client has an ASA5505 anchoring an MPLS network. One of their branch offices is experiencing frequent circuit outages due to theft of copper lines. I am looking at an 881G with wireless aircard as a backup solution and creating a VPN tunnel to the ASA but am unsure about how to handle routing on the ASA. There will already be a route for the branch subnet for the MPLS network.

so we have been using our current ASA5505 for a long time. Since it only support up to 10 VPN licenses, so we buy a new ASA5505-SEC-BUN-K9(support up to 25 users).
the old ASA are running: 8.0.3 and ASDM 6.0.3
the new ASA are running: 8.2.5 and ASDM 6.4.5
I thought it would be simple as export and import the config file, but when i tried to restore, the new one is looking for a zip file but the old one doesn;t backup file in ZIP. It looks like i need to update the ASA version or/and ASDM?
I am pretty new to this and never upgrade any of these versions since I am aware of the upgrade may mess things up. So do I need to upgrade both the ASA version and the ASDM in order to restore my config? any effect if i do the upgrade? I also read some articles, we need to upgrade on the version one by one, like 8.0 to 8.1 then 8.2?

I am wondering if it's possible to convert a Pix 501 configuration running version 6.3(5) to a new ASA5505 which we just purchased? We have site to site VPN on this device and i am just trying to save some time. I believe Cisco TAC might have a tool to do this but i am not sure.

Short version is we cannot communicate between our subnets.We have a Cisco ASA 5505 we are using for our network router. We have a Netgear L3 switch behind that with 10 vlans. Each VLAN is on its own subnet. (10.0.10.x/24, 10.0.11.x/24, etc)We have PAT for each subnet to our outside interface. Each subnet NATs out properly currently.I have NAT exemption enabled for 2 of the subnets (eventually I will need all, but am just testing at the moment). I have tried multiple ways for the NAT exemption to allow all traffic from our inside VLANS. At this point in time I am trying to get "Engineering" to communicate with all hosts on "AuthUser". I can ping some hosts, but not as many as if I am directly on the interface. I can reach a port 80 service, but not 443. I cannot access anything via hostname or NetBIOS.What am I missing to allow higher security level interfaces to fully communicate with lower security level interfaces?

We care currently using an ASA5505 as our firewall and redirecting web traffic to a S160 Iron port. Recently the web filter stopped working and the only way to get filtering again is to reset the redirection.
1. Is there any available log information to find out about the WCCP process and maybe way it stops?
2. Are there keep alive packets or anything of that natural between the ASA and Ironport?

I have a cisco ASA5505 configured in transparent mode. This evening we attempted to plug a couple of new servers in but they simply didnt work, despite our test server working absolutely fine. The server IP's are all in a network object group (the same as the test server) and they're all using the same ACLs etc. I'm relatively new to configuring cisco equipment.
the only thing I can think of is a static route I had to add to get the managemet IP to work might be causing problems.route outside 0.0.0.0 0.0.0.0 XX.XXX.132.1 1(IP addresses obfuscated- servers are all in the same range so assume XX.XXX is the same across all IP's).

I’m trying to configure my ASA 5505, in order to allow my inbound and outbound mail communications. Here with this mail I’ve attached a diagram which illustrates my exact network setup along with ip addresses.
In this setup I’ve enabled port forwarding on my ADSL router (port 25 and 110) and configured the ASA accordingly, and my mail server is located inside my network.
My problem is currently I can send mails from my inside network to outside but my not receiving any mails which originate from outside. I’ve attached my current ASA configuration as well,

I have noticed a problem recently that our Remote Access VPN will randomly stop working. I will be able to connect and enter my Username+Password and it says Connected, but I cannot ping Remote Resources. If I check VPN Client Statistics, it shows Many Packets Sent/Encrypted, but None Received. It seems this problem affects all devices at once, but leaves the L2L tunnels intact.
It seems to randomly start working for a while, and everything seems fine until it stops working again. I verified that it is not a firewall problem, and it occurs on multiple ISPs and computers.
We also have 2 Static L2L Tunnels, and 1 Dynamic L2L Tunnel all of which operate flawlessly. All sites/remote users use split tunneling.
Below is the config, I just added the keepalives on the RA Tunnel to see if it would work, I haven't noticed any difference yet.
ASA Version 8.0(2)

We have 2 ASA's that connect to a 2811, but for some reason, the 2nd ASA wont connect anymore. Debuging ipsec or isakmp on the 2811 doesn't come up with any messages.
External IP's still correct, and the sites can ping each other.
Only debug on ASA for crypto isakmp comes up with messages (ipsec doesn't give any messages).
ASDM says:
Removing peer from peer table failed, no match!
Error: Unable to remove PeerTblEntry
I found some info on the above error messages, but those links didn't quite useful.
Below is fromt he debug on the ASA:
