I have a command line from ASA 5505 like below :
nat (inside) 0 access-list NO_NAT
The problem is I cannot see any matching ID of 0 at the (outside) like :
nat (outside) 0 xxxxxxxxxxxxx
Another problem is there is also no any access list with the name of NO_NAT.
We are configuring a twice-nat to send traffic for scansafe, its on a asa5505 ve 8.4(3) on a remote location for the customes. The nat redirecion is working but we also have a VPN tunnel to the corporate network. Through the tunnel we need to reach a http server. The problem we are having is that when we add the scan-safe nat, all http traffic gets redirected to scansafe, includind the traffic to the http server on the corporate network.
10.2.1.0 ---<ASA5505> ---Internet,scansafe ---- <Corporate> --- 10.1.1.0
the http server is 10.1.1.75
the remote location network is 10.2.1.0/24

I have a Cisco ASA running 8.2 in routed mode.The ASA has three interfaces, inside, outside and DMZ. They connect to the following three networks:
Inside: 10.1.1.0/24
Outside: 10.1.2.0/24
DMZ: 100.1.1.0/24
I have the following dynamic PAT configuration:
nat (inside) 1 10.1.1.0 255.255.255.0
global (outside) 100.1.1.1
nat control is turned off.
By my understanding any traffic from the inside to outside interface will be PATted to 100.1.1.1. However, communications between inside and the DMZ will not be PATted, and should work with no problems.This seems to be corroborated by this document: [URL]Which states:"The adaptive security appliance translates an address when a NAT rule matches the traffic. If no NAT rule matches, processing for the packet continues."EDIT: I may have misunderstood the above statement.I found this guide to configuring NAT/PAT: [URL]It states:"When you specify a group of IP address(es) in a nat command, then you must perform NAT on that group of addresses when they access any lower or same security level interface; you must apply a global command with the same NAT ID on each interface, or use a static command. NAT is not required for that group when it accesses a higher security interface because to perform NAT from outside to inside you must create a separate nat command using the outside keyword. If you do apply outside NAT, then the NAT requirements preceding come into effect for that group of addresses when they access all higher security interfaces. Traffic identified by a static command is not affected."My problem is that packet tracer does not seem to bear me out. It tells me the packet is dropped due to "no matching global" when I source traffic from the inside interface and send it to the DMZ.

We have a cisco asa 5505 on which we have setup a group VPN. The VPN connections from all cisco vpn clients works fine except one. The keep getting the below error
"Secure VPN Connection terminated locally by the client. Reason 412: The remote peer is no longer responding. Connection Terminated".
Not sure why only one client won't be able to connect. The version we are using is 5.0.02 for VPN client.
I am unable to Telnet/SSH/RDP from my inside network to my DMZ. I am not sure where the problem lies, I am able to use VNC from the inside to the DMZ (ports 5800, 5900), and also establish connection on Ports (26700-26899). I have a computer connected directly to the DMZ and those services work to all networks on the DMZ.I have attached Logs of successful VNC connections, unsuccessful RDP and Telnet sessions, and the running config.

Everything works perfectly except when I try to sent an email. The email gets sent (eventually), but afert a long waiting time, 45-60 sec. The connection is opened instally to the server but then just hangs there for 40-50 sec. The problem is that a have an aplication on a server that has to send confirmation emails, and that aplication is limited to a 30 sec timeout for conecting to the mail server, much less then the 45-60 sec that I have now. The mail server is hosted by a data center, it is not in my networks (location).
I have tried deleting the ESMTP inspection, that doesn't work. Pinging my mail server rezults in a average time of 20 ms. And when a do a tracert the hight value in a hop doesn't usually pass 80 ms, the average is 20-25 ms.
The problem is ONLY when sending emails. Everything else works perfect, including receiving emails from the same server.

I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA. I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.

I am using two firewalls to connect two different offices. Firewall 5510 is running ASDM 6.3 and 5505 is running ASDM 6.2, Problem is that even after connecting two sites, i am unable to ping remote network from either side. I am mentioned static route as tunneled.
View 1 Replies View RelatedWe have a client that has a Cisco 1801W Firewall that is setup as a site to site VPN terminating to a Cisco ASA 5505. The tunnel is up and established, I can ping from both sides of the tunnel.
The problem is the clients behind the Cisco ASA (192.168.2.x) cannot reach certain ports behind the Router (192.168.1.x). The main thing we're trying to do is browse via UNC path (ex: \192.168.1.120 from a 192.168.2.x machine).
I got 3389 working after I changed the - ip nat inside source static tcp 192.168.1.120 3389 y.y.x.x 3389 route-map DM_RMAP_1 extendable Modified the command to include the public IP instead of interface FastEthernet0
I believe it has something to do with the way NAT and route-maps are setup currently but I'm not familar enough with them to make the changes. I worked with Cisco to ensure the VPN tunnel was fine and it's something security related on the Router.
Here is the configuration (removed a few lines not necessary. y.y.x.x = WAN IP of Router x.x.y.y = WAN IP of ASA).

I believe that the Cisco Unified Communications Manager Express matches the outbound VoIP dial peer digit-by-digit, because:
1. when using the debug command it shows how it works digit-by-digit till it match a pattern
2. It says in the study guide ( If a match is found, the router immediately processes the call - chapter 6) so I understand its not en bloc
my config and all the show's ive run sofar tryign to figure this out, but the policy map isnt matching the traffic for some reason

I'm performing tests with following desired scenario: We have several remote offices, connected to our HQ via MPLS. In these remote offices, we have several vlan's. Each vlan has it's own ip-range. The MPLS cloud is routed, so we cannot switch our HQ vlan's to the remote offices. In this case, the client pc is in a guest vlan which allows him internet access. The uplink for this internet access is hosted in our HQ datacenter.
basic scheme:
client pc --> MPLS cloud (managed by ISP) --> 6500 switch LAN --> Checkpoint Firewall --> 6500 switch DMZ --> ASA Firewall
My test scheme:
Client pc is in a subnet A (guest vlan range office).
We receive this traffic on our first LAN 6500.

My company is composed of three different campuses, all with a similar network topology. We currently are experiencing high bandwidth on our serial interface at one of the campuses in particular. The network is composed of about 20 VLANS routed internally using a Cisco 6509. Traffic to the outside is PAT’d by an ASA 5510 and then forwarded through our edge router interface. Each VLAN is PAT’d to a specific public address.Due to the PAT, how would you recommend determining what specific private addresses are consuming our resources on the serial interface. When I look at our NMS, it reports the public address, but that only narrows it down to a VLAN. For example, all the devices in VLAN 6 are translated to 146.34.118.245, and 146.34.11.245 is a top talker.
