I'm using ASA 5515X my concern is I was not able to block the traffic of P2P such as BitTorrent etc. I was also view some technotes on how to use webfilter without using Websense or Smartfilter tools and lucky I'm able to block certain websites. how to block the traffic of P2P?

I have an ASA 5520 with the below config
Gi0/0: outside (Internet)
Gi0/1: inside (Internal users)
Gi0/2: DMZ (web servers, ftp, Mail etc..)
I have a SMTP relay deployed on the DMZ for mailing. I have also a mail servers installed in the internal lan,
I want to allow trafic from dmz to reach internal lan, and i want normally also allow stmp relay from dmz to reach Internet.
How can i block trafic from DMZ to reach Internal Lan (instead of smtp) if the to allow trafic from dmz to internet i must put ANY in the policy?
For allowing trafic from DMZ to reach Internet, the policy must be DMZ -----> ANY ----->Services., this policy means DMZ can implicity reach Internal Lan?
Is it possible to block internet traffic on the PC using ASA5501 firewall which is used in transperent mode.The DHCP pc is working fine we just need to pass through ASA to block the internet on the pc however intranet should be available.

I have an ASA pair configured to replace a router that hosts a collection of IPSec Tunnels. Tunnels appear to work. I am lab'ing some additional controls that I would like to implement. On the Production Router that i plan to replace with the ASA's the current Tunnels are all wide open (all traffic allowed to pass). I was hoping to lock things down a little without having to reconfigure all of the Tunnels. My though was that an ACL on the Inside Interface blocking selected traffic Out (so into the LAN) should not impact the stability of the Tunnels but allow me to restrict some traffic from entering the LAN. One port that I was attempting to block is RDP 3389. When this ACL is applied to the inside interface it does not block Port 3389 at all. What am I missing? Is it that the trffic is being allowed because it is coming through one of my 'open' Tunnels?
Shouldn't IPSec Tunnel traffic be processed by the Inside Interface ACL just like all other traffic?

This work great on a 2821 Router, but not so much on the ASA.
I will be implementing a new firewall (cisco asa 5515x) on my existing 3750x (server switches) and my 2960s (user switches). What should I need to apply on my firewall and swtiches to make the implementation successfull. I will put my 3750x as my DMZ and my 2960s as my inside. The 3750x have multiple subnet and also the 2960s.which features and technologies i need to know on those 3 products. my 3750x and 2960s don't have any ACL defined and most common features are vlan, switchport, trunking, spanning-tree, stacking, vtp.how my asa knows that my 3750x/2960s have multiple vlans. my current connection right now on 3750x and 2960s is just through 6 ports i assigned as one trunk, below is my config [code]
my 2960s vlans are almost the same with my 3750x except vlan 160, 170, 192. but of course when i put this in asa, i have to segragate vlan for 3750x (192, 100, 110,160, 170) and 2960s (130, 150). for my 2960s connection to the asa and since this will have big bandwidth, i will use 3 ports on my asa (and trunk it) connecting to my 2960s and i will use 2 ports on my asa (and trunk it) connecting to my 3750x. the one internet ports and my one management ports on my asa will stay like that.
I have a strange issue which happened to me last weekend with two ASA 5515X on version 8.6(1)2. There was a planned power shutdown which only affected the primary firewall. Failover was configured and running successfully. The configuration was also saved after every change made. After power was shut and primary firewall went off the secondary took over like it should but unfortunately all configuration was gone. We immediately powered on the primary again but also this one lost the configuration.
While reconfiguring the firewall we ran into another problem. The devices won't pair although it was the correct configuration. After three times removing and adding the same failover configuration the devices accepted the failover and worked together again.
I went through the bug toolkit and white papers regarding ASA 5515x and this particular version but were not able to find anything.
My customer has a rather complex configuration on an ASA 5510 running version 8.2.
They are migrating to new ASA 5515X models which of course only version support 8.6
How can i convert the configuration from 8.2 to 8.6 since the new ASA's do not support the earlier versions?
The X series seems to be a great option for new deployments but what about replacements of existing older models?
I am in a process of replacing the Cisco ASA 5510 with 7.3 OS with a new Cisco ASA 5515X with 8.6OS. In the existing Cisco ASA 5510, we have configured 'no nat-control' for which the traffic from all sub-interfaces were flowing to the lower security interfaces without any NAT command. Just access-lists were configured. Now how do i acheive the same in the Cisco ASA 5515X with 8.6? I do not find any 'no nat-control' command available for it.

View 1 Replies View RelatedI have a FWSM cluster that I exceeded the maximum number of static nat entries on. i migrated the connectivity off to a pair of PIX 535's that seem to be handling the adderess translation needs. however the number of NAT entries being required is increasing and being the PIX series wal EOL'd several years back..I need to replace them.. The static 1-1 nat entries cannot be summarized into network as the hosts that are being nat'd are scattered all over various micro subnets in the all 3 rfc1918 ipv4 address ranges and they are being manged directly by snmp and SNMP-trap and other services that prohibit the use of many-to-one nat. Is there a mknown maximum number of static 1-1 nat entries that can be defined on the ASA 5515-x, 5525=x and higher ASA firewalls? Say I wanted to be able to grow to 2500 or more static 1-1 nat entries. I am currently running 2010 1-1 static host nats currently.

View 5 Replies View Relatedwhere is the best place to block unwanted traffic? By that I mean, should I block it at the router, firewall, IPS? As an example, I'm dealing with DNS flood attacks - probably DDoS and reflection. I have a pair of Cisco 2821 routers with two different ISPs doing BGP. Behind that I have an ASA 5510 with IPS module. Behind that I have 2 public DNS servers. Over the last few days I've seen an increase in bogus DNS queries - high volume, distributed. My question is where is the best place to put the ACL to block them? I've been putting them on the ASA, but when the attack is running, it jacks the CPU to 60%. If I don't put the ACL, the IPS seems to pick them up after a while and the CPU is almost as high as with the ACL. I haven't tried to put the ACL on the routers.
