Cisco VPN :: Setup A Remote Access VPN On ASA5505 Firewall

Jun 2, 2013

I have setup a Remote access VPN on my ASA5505 firewall through the ASDM wizard.I can successfully connect with the Cisco VPN client. My firewall also shows me the VPN session and shows incoming Rx packets. However, Tx packets remain 0, so no traffic is going out. My ASA5505 is configured as router on a stick with 25 different VLAN's. I want to restrict traffic to one specific VLAN using a crypto map.When I issue a ping -t command on my connected Windows box, the firewall log shows me the following message:
"IKE Initiator unable to find policy: Intf outside, Src:, Dst:"
"This message indicates that the IPSec fast path processed a packet that triggered IKE, but IKE's policy lookup failed. This error could be timing related. The ACLs that triggered IKE might have been deleted before IKE processed the initiation request. This problem will most likely correct itself." [code] I have really no idea what's going on. I have setup a Remote access VPN countless times but this time it shows me the error as described above.

Cisco VPN :: ASA5505-SW-UL Any Connect Setup And Able To VPN Into Office

May 9, 2013

I have a Any Connect setup and able to VPN into my office.i bought a ASA5505-SW-UL that is unlimited user (UL) software license but now the vendor tells me that: From the ASA you can saw the unlimited license is for inside hosts, instead VPN client's, by default, ASA 5505 included only 2 VPN client's and can supported up to 25 VPN client's, your license look only default 2 VPN client's. If need more VPN client's connect, you have to purchase the additional VPN client's license. I am just wondering his statement TRUE/FALSE, because i thought ASA5505-SW-UL means unlimited license

Cisco VPN :: ASA5505 - How To Setup Windows Client

I have just purchased and setup a vpn on my ASA5505 and now I wish to setup a Windows VPN client to use it. Does CISCO have any free vpn clients for Windows?I tried to download a client from the CISCO downloads area, but it's for some kind of purchase agreement. I would have thought that the vpn client was free to download given my ASA comes with two free vpn licenses.

Cisco Firewall :: Users Behind ASA5505 Firewall Are Unable To Access Internet

Feb 24, 2011

I have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.

When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.

The ASA5505 configuration is shown below.

Cisco Firewall :: ASA5505 Can't Ping New Firewall On Inside Interface

Jul 14, 2011

I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.

From Juniper SRX, am able to ping public Internet IPs (

1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30)
2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.

Cisco Firewall :: ASA5505 Firewall Rule Not Blocking

Apr 1, 2013

I'm trying to troubleshoot an ASA5505.
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic.  I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did.  That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below.  However, it appears to have had no real effect and the hit count is very low (it should be astronomical).

Cisco Firewall :: Using IP Aliases On ASA5505

Nov 29, 2011

Is it possible to use IP "aliases" on an ASA5505 to use as static NAT public IPs to private IPs?  For example, I have int e0/0 connected to my ISP using a /30 subnet and I have my private LAN connected to e0/1 with a /24 subnet.  At the moment I can use the one usable IP from the /30 to NAT to the private LAN.  The ISP is also routing a /28 subnet to the one public IP of the ASA. I would like to use some of the /28 IPs for NAT also.  Can it be as easy as just adding the NAT commands? I figure I would have to add that subnet to the ASA somehow, no?  In other devices (including the SA520) they use a concept called IP aliases whereby you define what additional IPs the device can use in its NAT config.  Does the ASA support aliases?  Maybe I have to do something with VLANs?

Cisco Firewall :: Routing Using ASA5505 And Pix 501?

Jun 16, 2011

I have 1 network that I'm trying to make secure, and it needs to access 2 seperate networks.   I tried using an ASA5505 that I had on the shelf to accomplish this but discovered that I had the basic license and that was prohibiting me from getting my connection to my 3rd network.  I scrapped that idea and grabbed an old pix 501 off the shelf to bring my connectivity to my 3rd network online since the 3rd network is only passing ip traffic to a small group of servers on the outside I figure the 501 should be just fine.
So, here's the problem I am running into:My internal network is, I have a new domain controller with DHCP on it handing out addresses in the range.External Network 1 is  The services I need from that network are primarily in range, however there is a comcast router (Changed of course) that provides high speed internet I need for my www traffic.External Network 2 is  I have about 4 servers I need to access on this network and that's it.   This network has it's own domain and DHCP controller and I've been given a range of ip's to use on this network of My switch is just a plane jane 3com switch with minimal management so I am attempting to use my ASA5505 to handle my layer 3 routing. 
So here's my issue:ASA5505 (IN:, OUT:  Passes traffic to External Network 1 and to the comcast router, no problem.   All my computers on my network have access to everything on as well as getting full name resolution and www traffic across the comcast router.  Can NOT access no matter what.  From inside the ASA or from on the inside LAN ports.  It CAN ping the PIX 501  PIX 501 (IN:, OUT:  Can ping EVERYTHING.  Can ping, can ping and can ping    Set to globally assign the other IP's in my range as addresses for outgoing traffic.Workstations (IN: 10.10.16.XXX DHCP, using as gateway)  Can only access everything on External Network 1.  ZERO access to External Network 2. ATM I have both INSIDE and OUTSIDE ACL's wide open for both firewalls just to get connectivity going.  I will be tightening it up after it is operational.Attached find a log file (Sensetive data removed of course) that contains the sh run and sh ver for both the ASA5505 and the PIX 501.

Cisco Firewall :: Configure Dmz On ASA5505

Dec 20, 2011

I have a asa 5505 Sec plus with 3vlan, inside, outside and dmz.
On the outside i have 5 ip's for my use, and in the dmz i have a webserver that need to communicate with one sql server on the inside.
The "sql" also needs to be accessible from outside and thus has a static nat with a dynamic nat so it replies from same ip as on nat ie webserver is natted with
sql inside ip is, gw
webserver ip is gw 
sec lvl on inside is 100 and on dmz 50
with a dynamic policy  running inside-net/24 to dmz-network/24 translagt to dmz i can get it to ping 1 way from inside to dmz, but not the other way around...
All i need is to open 1 port  ie 6677 both ways for this communication to work.
I'm not very familiar with the CLI and do most stuf in GUI  (know i should learn CLI, but time doesnt let me)...

on access rules i have just added everything from any to any using , ip, icmp, tcp and udp just to be sure...  :-)

Cisco Firewall :: DNS Redirect On ASA5505?

Feb 29, 2012

I want to make it so if a user tries to use a different DNS server the request will be redirected to the one they should be using.I thought this might work but the ASA doesn't do PB routing
ip access-list extended transparent_dns
permit udp any any eq 53
route-map redirect_dns permit 10
match ip address transparent_dns
set ip next-hop ip.of.your.server
route-map redirect_dns permit 20

The DNS server is windows 2003?Would policy based NAT or WCCP work for this? If so how would I go about it?

Cisco Firewall :: Trying To Get ASA5505 To Route

Nov 14, 2012

customer's WAN solution, instead of buying routers, purchasing department bought ASA's (don't even get me started!). So I have 5 ASA 5505's for the branch offices and one 5510 for the Head Office. I am trying to get them to behave like routers and pass the traffic across. I set up a lab with a 5505 and the 5510 using an ethernet cable for both Outside interfaces since the WAN links are going to be MetroEthernet Layer 2 anyway.
I tried static routes, dynamic routing, I followed examples from other persons who did it and it doesn't work. I attached the configs here to show I have the default routes, specific static routes pointing the traffic out, any any rules configured as well. I cannot ping from the internal lan of the 5505 to the internal lan of the 5510.
