I want to restrict outgoing traffic. Currently the deafault any, any IP allows all traffic from the inside to the outside.
So I created some rules to only allow HTTP and HTTPS. First I configured a rule to allow all DNS (TCP 53) traffic out. Then I added a rules to allow HTTP (TCP 80) and secure HTTP (TCP 443) out.
When I apply and try to surf out to the internet from a box on the inside network I cannot. Remove the rules which returns the default any, any IP and traffic flows.
Packet tracer shows that the traffic should flow. And I have had minor traffic flowing but slow.
how to only allow web surfing from the inside to outside using the ASDM (5.1) to configure? I realize this is probably a very simple thing, but I only configure the ASA about once every year!
I am running CSD 3.6.5005 with Asa code 8.4(3) and asdm version 6.4(7). I have anyconnect premium and advanced endpoint assessment licenses installed with anyconnect essentials disabled. I have the standalone CSD package which hostscan is activated through.I am able to create host scan checks for registry and operating systems and have built dynamic access policies. The issue that I am experiencing is I can't get the av vendors to appear when configuring the advanced endpoint section. I keep seeing a pop with a blank screen when I try to add.I am using OSX lion and I have tried on windows also. I have tried on a 5505 and now on a failover set of 5510s.
VLAN 20 and VLAN 30 i configured. VLAN 20 interface IP : 192.168.20.1/24 VLAN 30 interface IP : 192.168.30.1/24. Inter-vlan communication is happening fine.
For testing for purpose i configured extended ACLs. Here is my requirement: I want to stop communication from VLAN 30 to VLAN 20 but not vice-versa.
Here i configured like this:
access-list 111 deny ip 192.168.20.0 0.0.0.255 192.168.30.0 0.0.0.255 access-list 111 permit ip any any applied ACL in VLAN 30 interface 'in' direction. ip access-group 111 in
In this scenario, communication is stopping in both directions. If i ping from one of the IP VLAN 20 to one of the ip of VLAN 30, i was gettng Requested time out. And if i ping from one of the IP VLAN 20 to VLAN 30 interface IP, i was able get pinging.
From VLAN 30 to VLAN 20, i was getting destination host unreachable from VLAN 30 ip( Its fine as its my requirement). So, solution needed to communicate from VLAN 20 to VLAN 30.
I have a standard ASA 5505 with inside, dmz and outside with the default security levels, 100/50/0. we have an email server inside which has been NATed and is working fine. However users accessing the wireless on the dmz are unable to access their emails on https (443). How do I allow SSL access ONLY to users on the dmz using ASA 8.4 commands or ADSM 6.4?
So I've run into a problem on my ASA5510, post-upgrade I can no longer connect to the inside interface from across our L2L VPN. I've tried both ASDM and SSH and the connections fail. I see in the logs that the attempt is being made, but it will eventually time out. There have been no problems with this type of connection with any previous upgrades, just this particular upgrade, I went from 8.4(1) to 8.4(2). I don't see much in the release notes or anything in a pre/post config diff that jumps out as a cause to this behavior. The only thing I did see in the release notes "CSCtg50770 Mngt-access (ASDM,SSH) to inside intf of 5580 fails over RA VPN session" which sounds like it could be my problem, but that was in the "Fixed in 8.4(2)" section and says it's for a 5580, maybe the fix for the 5580 broke it on a 5510??? I hope not and that I'm simply missing some new setting that I need to enable for this type of connection as this device is in a remote office.
I'm screwing around with HSRP running between two L3 interfaces of routers. I placed an inbound and outbound ACL on the same interface on both of these routers specifying to "permit ip any host 224.0.0.2" Why am I only seeing counters ticking for the inbound ACL of both of these routers? Is it an order of operations thing?
I have a 2960 SI lan lite switch that I am configuring for admin and guest access. I have wireless AP's plugged into trunked ports 2 and 3. I am using two vlan's (in addition to the native VLAN). Vlan 5 for Admin and Vlan 10 for guest access. I have ACL configured on the router preventing guest users from accessing the Admin network. I want to prevent those on the guest network from seeing other hosts in the vlan however the lan lite software does not support port ACL's. Any way to accomplish this with this switch.

I am running the Startup Wizard from my browser as I do not have a Console Access for a brand new CISCO ASA and I am stucked with the User? Password ? I tried many combination and nothing worked.
I'm almost afraid to post since my stuff is so OLD! I have a 350 Series PCI Wireless LAN Adapter in my old WinXP, not wireless-ready Compaq.I live off the grid, no landlines and have been using a Franklin CDU680 USB air card to connect to the Internet. The air card doesn't like my Compaq - occasionally crashes it. I thought to put the air card in a router to solve the problem and communicate with the router using the Cisco 350. Bought a Cradle Point router from my ISP and plugged in the Franklin. Then spent the next 5 days trying to get the Cisco 350 to associate with the router.I now have a profile with the router's SSID in it that according to the ACU's status report is associated with that SSID. Problem is that there is no Internet connection.
Currently a customer has all theLAN devices using a router as the Default Gateway. The router also do the Dynamic NAT to the internet access and has NAT/PAT rules to publish some services like HTTP and FTP. As I know the router will permit all the incoming traffic in all its interfaces without restrictions at less there is an ACLs that restrict the incoming traffic on an specific interface.Now the customer has bought a brand new ASA and wants to use it as the default gateway for the entiery LAN. This means, the ASA will have the internet connection and will be the responsible for the NAT/PAT process.
I have configured the NAT/PAT rules already following the current router configuration, but I need to know if I have to configure ACLs allowing the incoming traffic on th Outside interface for the services I NATed.
In the near future I plan on updating all of my firewalls to 8.4, currently we're on a mix of 8.0 and 8.2. I've heard that if your equipment is on 8.2 there's an auto-conversion feature when upgrading to 8.3. However, I do not want to rely on that and am trying my hand at re-writing the NAT and ACLs myself. Attached is my pre 8.3 ASA 5510 config (santized) and a document that shows the particular sections pre 8.3 and what I think they should be after the upgrade.
I'm having a bit of trouble determining the best way to do this... I have 12 V LAN's set up (sub interfaces on a redundant group of two NICs) on my ASA 5510. On several of these, I want them to be able to access the internet but not access other V LAN's.
By default, they have a rule like "any to any less secure", and since the outside interface has a lower security level, this works great. But if I create an ACL on the interface, this rule disappears. I can restore internet access by adding an "any to any" or "(this interface's sub net) to any" rule, but this seems to imply that it allows access to any v LAN. Do I have to create a set of "deny" rules for each V LAN, on each V LAN, followed by an any-any rule to allow internet access, or is there a cleaner approach?
It is my understanding that ACLs can only be bound to logical interfaces using the access-group command. However, is it possible to somehow apply ACLs simply based on the ASA's local Ethernet interface? For instance, consider the following:
Device A with IP 192.168.1.1/24 is connected to Ethernet0/0 on the ASA. Device B with IP 192.168.1.2/24 is connected to Ethernet0/1 on the ASA.
Since both devices are in the same subnet and presumably the same VLAN, is it possible to manipulate the traffic to and from physical Ethernet interfaces using ACLs in this manner?
My predicament is fairly simple:
Internet --- ASA --- ROUTER | DMZ
In addition to NAT, VPN, and various other tricks, my ASA is also routing traffic from my internal LAN and the Internet to servers in the DMZ configured on the ASA. Due to a combination of Internet and DMZ traffic, my relatively slow ASA is struggling to route and thus becoming a bottleneck. My router is comparatively modest in terms of functionality when compared to the ASA but it is fast. My ideal solution would be to somehow harness the ASA's filtering capabilities for my DMZ but use the router to get traffic to and from my internal LAN into the DMZ without using the ASA to route it.
Additionally, it is worth noting that my DMZ is fairly restrictive so using protected or isolated ports would not quite work for me.
A CISCO 3750-X stack with several VLANs and many ACLs applied to the virtual interfaces. Intervlan routing is on. Connected to this stack are VMware hosts and with about 500 VMs.We started using the ACLs to allow connectivity between VLANs to specific hosts and it has grown to thousands of lines. I personally do not think this is good for the switch and believe the switch was not intended to be used for that security feature.
- Does it make it sense to add an "internal firewall" between the CORE ROUTER AND THE 3750-X SWITCH STACK ?
- Do you recommend any other way?
- Any recommended CISCO resource/white paper to read about best practice
I have found this in documentation (the same statement for version 8.3 and 8.4):
" Access Control Implicit Deny #All access lists (except Extended access lists) have an implicit deny statement at the end, so unless you explicitly permit traffic to pass, it will be denied. For example, if you want to allow all users to access a network through the ASA except for one or more particular addresses, then you need to deny those particular addresses and then permit all others. "
Does it mean that now all ACLs shoud have created manualy deny ip any any rule at the end ? I have migrated one ASA to version 8.3 (no host connected and I can't test it) but after migration I don't see this rule at the end of all ACLs. Does it mean that all traffic will go throu ACLs on all interfaces ? I didn't find any information about this change in documents describing new software features [URL]
I have an ASA 5505, firmware 7.2 (4). Configured ACLs, NAT, it's all working, but after a while it seems that running crashes, no longer makes the directions of NATs, the logs until they stop working. To resolve, I have to restart the ASA, and everything will work again.
create a VPN dongle for my office users. I have Cisco ASA 5005 firewall. I want to give them remote access to our intranet but if the user doesn't have the dongle which has the certificate on it he/she can not connect to my office intranet.
I would like to configure an ASA5512-X in firewall transparent mode, but I am having trouble getting ASDM to lauch when I do.
I have created a BVI interface with an IP address, and I hve enabled the mangement interface, but ASDM does not lauch when I enter the IP adress of the BVI I created.
Apprently you need to use the bridge-group command to assign an interfce to a bridge group. When I enter this command at the (config-if) prompt for Management 0/0, this command is not recognized.
What are the general steps for configuring the management interface to be able to launch ASDM in transparent mode?
I would just like to to open UDP port 123 in the ASA 5510 Firewall so that our Primary Domain Controller could use this port to sync time with an external time source. We have already added an access rule for this port under the firewall configuration in ASDM 6.4 and this port was also allowed in the inbound and outbound rule of the PDC's Firewall but it seems that it was still blocked.
I have an ASA 5510 in a live environment. Up til a short while ago I could access this via the ASDM and ssh. However I can no longer connect to it via eithier. When I access It via SSH I get a disclaimer saying the following
*** You have entered a restricted zone! Authorized access only!!! Disconnect immediately if you are not authorized user! ***
It then cuts me off.
When I try to access the ASDM I get the following

I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?
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.
I am trying to configure our ASA 5505 so that our users can access our ftp site using [URL] while inside the firewall. Our ftp site is setup so that you can reach it by either browsing to the above url or by browsing to ftp://99.23.119.78 but we are unable to access our ftp site from either route while inside the firewall. We can access our ftp site using the internal ip address of 192.168.1.3.

I have two control point, two firewall the second one is linked inside one DMZ from the first firewall route is good and inside the DMZ from first firewall I have servers too.so to be more clear we could call as IP for the DMZ from first firewall, Interface IP 1.1.1.1 that generate this DMZ with first firewall (netmask 255.255.0.0)
inside the DMZ I have an interface from second firewall with IP 1.1.1.5 and inside DMZ 1.1/16 I have servers too keep one test server with IP 1.1.1.3.The LAN passing the second firewall is 2.2.2.1 ever 16 bits of netmask (255.255.0.0) inside the DMZ generated from second firewall I have a machine with IP 2.2.2.9 that need to access in TCP services on machine 1.1.1.3
TCP packets from 2.2.2.9 pass the second firewall and arrive inside DMZ with net 1.1/16 and arrive to server with IP 1.1.1.3 defaul gateway (to answer to originating machine with IP 2.2.2.9) is 1.1.1.1 ASA interface 1.1.1.1 claim a missing related as it haven't mapped the connection that has passed on first firewall.

im working on a small project on a asa 5505 and beacuse i do most of the work from the outsidei want to open up asdm without vpn.
i have it working on another asa and the only difference is the rom version.the one not working is 8.0(5) - 6.2(3) and the one working is 8.0(4) - 6.1(5) did they do some changes?
ASDM cannot be loaded. Click OK to exit ASDM. Server returned HTTP response code: 503 for URL...
I'm attempting to access the ASDM externally (where x.x.x.x is the external IP). I was able to access 3 days ago just fine. So far, I've found suggest a reboot.
ASA Version 8.2(1) - I think the ASDM version is 6.2
