I'm currently using ASA 5510 with software 8.4.1 and I have an issue with nat configuration. I used the following config line:nat (inside, dmz) source dynamic LAN Pat1 destination Server1 Server1
The traffic is not flowing and when I use Packet Tracer, packets are dropped at the NAT rule with the following error: Drop-reason: (acl-drop) Flow is denied by configured rule.The only ACE I have is permit ip any any.
I have manually configured the Firewall ASA 5510 from existing PIX to match the configuration, however when I connect the firewall to the Network, no traffic is flowing in either direction. I have the Inside network on the 172.29.0.0 subnet and the outside network on 20.2.0.0 subnet. I am attaching the cofiguration file.

So far I have setup NATing on two VLANs, one called 16jda (VLAN 16 - 10.16.2.0/24) and one called 16jdc (VLAN 11 - 10.105.11.0/24).
From each subnet I am able to connect to the internet, but I need these subnets to also be able to talk to each other.
I have each VLAN interface at security level 100 and enabled "same-security-traffic permit inter-interface", and I have setup static NAT mappings between the two subnets, but they still can't communicate.
When I try to ping there is no reply and the only log message is: 6 Aug 21 2012 09:00:54 302020 10.16.2.10 23336 10.105.11.6 0 Built inbound ICMP connection for faddr 10.16.2.10/23336 gaddr 10.105.11.6/0 laddr 10.105.11.6/0
im attempting to setup a L2L VPN between an 1841 and an NSA 2400, via the SDM.The Tunnel comes up, and when I test connectivity it shows as being successful, but I do get an error stating:-
"A ping with data size of this VPN interface MTU size and 'Do not Fragment' bit set to the other end VPN device is failing. This may happen if there is a lesser MTU network which drops the 'Do not fragment' packets."
From my reading this shouldnt cause all traffic to drop though, right?
Currently I cannot ping or telnet to services from one end of the tunnel to the other. I was able to ping momentarily from the Sonicwall end at one point, but this disappeared shortly afterwards (without my changing anything regarding the config).
All of the ACLs created were populated through the SDM.
i have a gateway router going to the internet....using public IP addresses on both interfaces. starting on Monday, traffic would suddenly stop flowing from the inside of the network going out, though i can still ping the outside interface , but when I log in to the router I am able to ping to the internet. so its like traffic is not passing from the outside int to the inside int. I have a 3900 router. other thing is, when i restart the router it will work for some time and then just stop again....

We are in the process of rolling out iPads to our offices. As part of this implementation, we need to print from the iPads to our network printers. Our network printers are mostly HP and Xerox and do not have native Apple AirPrint capabilities. As such, we have been using the FingerPrint software to share out the network printers as Apple AirPrint printers. We have a mixture of switches at our offices. Most offices utilize a 3550 PoE switch. In these offices the AirPrint traffic is being transferred successfully and everything works great. In the offices which are using 3560 PoE switches, the traffic is never seen at the iPads. We are using EnGenius EAP300 access points connected into the Cisco switches to provide wireless access to the iPads. Both 3550 and 3560 switches are running iOS 12.2(25). What might be stopping/blocking the AirPrint traffic on the 3560 switches?
View 3 Replies View RelatedI have a classical "inside + DMZ + outside" configuration.I also have a mail server in DMZ which have to be allowed to reach any destination on the outside (internet) at least on the SMTP port, of course.If I make an access rule that allows traffic from that server to "any", everything works fine, but doing so the server is allowed to reach any destination, including what is behind the inside interface (internal network).I didn't find any other option to tell the ASA machine to allow any destination, but on the outside interface only.I do believe is possibile to have the ASA to allow any kind of traffic from a host on the DMZ to the outside interface only, but I didn't figure out how.
P.S.: I'm using a 5510 machine running version 8.2
Just wondering if there are any methods or commands, natively, in the asa5510 for determining all traffic in to and from a certain server passing through the asa. This would be without a syslog server or something similar.

View 2 Replies View RelatedI have an ASA with an outside ACL that is configured to allow 208.84.248.95 SIP/5060 to 1x.x.x.46. I show no hits. I added an ACL to do a packet capture, it sees the packet coming into the ASA but not going to the Serv Prov interface. I see hits on the vuong ACL but not the production acl_out ACL.. What is up?
NOTE:ACL_out is the ACL we use to allow outside traffic to enter our network.

It was tested and verified from the inside network to make sure the server is listening on that port. Below we created an ACL to allow all IP from another test PC to the Server IP 1x.x.x.46. We did a telnet to port 5060 and it showed hits but not on the acl_out ACL.

Below we applied the same ACL to the ServProv interface to see if traffic was going where it was supposed to . By trying to telnet to the 1x.x.x46 IP from 63.x.x.140 IP. Looking below, no traffic appeared on the capture2.

Capture 1 above shows the last 3 incoming messages initiated from 63.x.x.140 to the 1x.x.x.46! Vuong ACL belows shows 3 more hits.....nothing on the acl_out ACL???

Im having problems with google saying we generate to much traffic to [URL]
I need to know which machines on the inside are talking so much with google. Can this be done via ASA 5510? do i need a third party program for this?
I use ASA 5510 and I would like to log VPN traffic ( for example, as soon as a remote user try to connect to the asa). I would like this log be send to a specific mail address. I already configure Email Logging for severity ( level 3) and it works well.
How I can add the VPN traffic Log ?
Is there any difference with traffic shaping capability on the 5510 as opposed to the 5505? is there anything the 5510 can do that the 5505 cant? with regards to TShaping?

I have little experience with firewalls, what I've learned has been by dealing with issues like this that arise from time to time.I know, I need to upgrade the version. It's in the works now. Anyways, my question/problem is: Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running contstantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.

ASA Version 8.0(4)
[Code].....
We are using an ASA 5510 as our gateway to our ISP. All of our VOIP traffic is sent to an Internet SIP provider for our outbound calls. Our pipe to the Internet is 100Mbps metro ethernet. I am trying to find a way to provide QoS for this traffic so that I can reserve 20Mbps of the available 100Mbps pipe for VOIP traffic.From what I've been able to figure out so far I would use a combination of priority queues and traffic policing. However, it seems that this is nearly impossible to accomplish because I cannot control the remote device that my ASA connects to because it is the ISP device. I could police traffic on the inside interface of the ASA. However, lets say that a client on our network starts downloading from an Internet host and the downloaded traffic saturates my Internet connection. I could police this incoming (from the Internet) traffic on my outside interface of the firewall. This would drop the packets but the bandwidth would have already been used by the time it reaches my firewall.Would the fact that I'm policing incoming traffic on my outside interface cause the sender to throttle down their transmit rate because packets are being dropped? Would this achieve my goal of guaranteeing available bandwidth for my VOIP traffic by not allowing other traffic to saturate the link?Most documents I find regarding this topic describe providing QoS for VOIP traffic traversing a VPN connection in which case you could configure both end devices.

View 1 Replies View RelatedRecently moved into the hardware firewall space and have a ASA 5510. Having some issues trying to get traffic through the box to my 4 dedicated servers. all the servers have static IP's and are connected to a private switch into one of the ethernet ports on the firewall(0/2). Public internet connection into another(0/0). 1 of my servers has a connection to the management port, and the public switch, and this is the one im trying to do the configuration on.
Im unsure what to set the IP address of my "outside" interface as. need to have RDP,FTP, HTTP traffic going to each of the 4 servers independently, pretty sure i can get the rules in place to allow this, but cant seem to get any traffic to go through the firewall to any of the other 3 servers.
I need to route to sub nets form 2 different ASA interfaces. The ASA also has an outside interface works like gateway for internet access. Here is my configuration:
ASA Version 8.2(1)
host name ICE3

interface Ethernet0/0
name if outside
security-level 0
ip address 201.199.xxx.xx 255.255.255.248

I would like to know if there is a way to apply in the Cisco asa 5510 traffic shaping not for a interface but a single IP address.For example i would like to limit the bandwith for the IP address of my FTP server.

View 2 Replies View Relatedenabling traffic between interfaces on the ASA 5510. Of course I have an outside interface E0/0 and an inside interface (E0/1) for normal operation. The idea was to enable one of the remaining interfaces on the 5510 to attach an internal network resource to for management in case we lost our switch. I am using E0/0 as the outside interface and the inside interface is E0/1. I am wanting to attached a management device on the same inside network IP address range for simplicity. I have E0/2 configured for the same security level (100) as the other inside interface and I also have enabled same-security-traffic permit inter-interface as well but I still cannot access the device on that port. Is there something else I am missing? I guess the best way to explain this is that I want ports E0/2 and E0/3 to act like a "switch" so to say...... The ASA 5505 lets you do this pretty easy but having trouble on the 5510.
