ACL should be applied to the port in closed mode
Hello
When reading about the deployment of closed mode of ISE, I came across conflict Cisco "HowTo-10-Universal_Switch_Config" and "Closed_Mode-25-HowTo" documents.
According to "HowTo-10-Universal_Switch_Config', in closed Mode, we must apply an ACL on the port of the switch as follows
Station Access IP DEFAULT ACL list
Note DHCP
allow udp any eq bootpc any eq bootps
Note DNS
allow udp any any eq field
Notice Ping
allow icmp a whole
Note PXE / TFTP
allow udp any any eq tftp
Note drop everything
deny ip any any newspaper
But according to "HowTo-25-Closed_Mode', in Mode closed, we don't apply this ACL on the switchport.
So my question is, if the ACL must applied on Switchport or not... and how it will affect switchport
Thank you
Aditya
Sorry for the delay, Aditya, as I've gotten very busy at work. Have you read the link I provided? Really, it offers different options to your question and answers.
Personally, I prefer NOT to set up an ACL and let the system use the default. However, if you choose this route, be sure that you always return a DACL with your authorization profiles, even if it is just 'allowed ip any any ".
Thank you for evaluating useful messages!

What is exactly in place at the port before RDP on WebVPN on ASA?
I've seen discussion elsewhere to use WebVPN of ASA and then using mstsc on Windows to send a normal RDP session through the VPN connection. Success is reported, but the recipe is not specified. I get the notion that it should involve setting up the port forwarding on the ASA. So if for example the forwarded port is 50001, then on the client system would connect through:
mstsc /v:127.0.0.1:50001
Who is suggested to http://microsoft-server-operating-systems.hostweb.com/TopicMessages/microsoft.public.windows.terminal_services/781703/1/Default.aspx - there are has similar partial reports elsewhere, as in http://hardforum.com/showpost.php?p=1035146809&postcount=5.
In our case, that administration of Cisco is in other hands - we are in a situation that is hosted behind an ASA dedicated to our use. What exactly should we ask them to obtain regular Windows RDP works this way? We tried Java and ActiveX, plugins but those are limited in different ways and do not always work on all client systems, so we want to try to use the RDP of MS client instead. We are not in a situation to require our users to install a VPN client software, so we need a way that works with the WebVPN. It is encouraging that other people have of this work. But we can not yet found where everyone has published a recipe in sufficient detail to pass on the exact instructions to our third ASA admins.
Port transfers the key for this? Or a "smart tunnel" would be an option? Thanks for any advice.
Pentecost,
Let's take a step back.
It works a lot like forwarding with SSH port forwarding. You indicate that some remote host/port will be available via this port locally (and Yes, that you connect through localhost:localport), java applet bit takes care of the rest.
Now smart tunnel (for programs) is a tricky beast, it is initially essentially all instances of a program to establish sockets via the tunnel.
Result? You specify that you want to connect to anything on the remote side, as if the program would be remote. Don't know if that makes senseIt is also smart tunneling of the bookrmaks and home pages, but it is a completely different matter.
If you are looking for something simple, but maybe not so... easy to use port forwarding should be fine.
Marcin
P. S.
I'm not familiar with the limits of the performance of the Terminal Server services in a tunnel smart (not to say that there is not).

Hello community!
I'm fairly new, when it comes to firewalls, but I have some experience with routers and switches, so I'm not completely lost.
Practically, we all know that a group object is a large bucket to throw things and then managing them as a single group, which is very useful for many reasons... so is there something similar that we can use in an ACL for the port?
Say so, let that I want to allow the following ports:
- 80
- 443
- 25
- 30500
- 20500
- 8080
- 14600
- 21
- 753
- 22
And instead of doing something like this:
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 80
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 443
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 25
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 30500
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 20500
access-list extended dmz_access_in permit tcp host WEB host WEB-EXT eq 8080
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 14600
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 21
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 753
dmz_access_in list extended access permit tcp host WEB host EXT - WEB eq 22
do something like:
dmz_access_in list extended access permit tcp host WEB host WEB-EXT eq PORT_LIST1
Thank you!!
PD: Excuse me if some port above are not TCP, if just one example. I just start typing all the numbers that came to my head.
Hey Rolando,
On a SAA, you can combine services and protocols based on the source/destination in an object-group service oriented. Your example would look like this:
object-group service PORT_LIST1 service-object tcp destination range 21 22 service-object tcp destination eq 25 service-object tcp destination eq 80 service-object tcp destination eq 443 service-object tcp destination eq 753 service-object tcp destination eq 8080 service-object tcp-udp destination eq 14600 service-object tcp destination eq 20500 service-object tcp destination eq 30500
You can create also integrate groups:
object-group service WEB_PORTS service-object tcp destination eq 80 service-object tcp destination eq 443 object-group service PORT_LIST1 group-object WEB_PORTS service-object ...
This type of group is going where the Protocol is specified in the ACL:
access-list dmz_access_in extended permit object-group PORT_LIST1 object HOST object EXT-WEB

ACL for only the port UDP Internet Permittin
Hello
I'm setting up a 3560 switch has 3 VLAN that is
VLAN 223 - Server - 10.4.223.0/24 - 10.4.223.1
VLAN 224 - user - 10.4.224.0/24 - 10.4.224.1
VLAN 225. -internet - 10.4.225.0/24 - 10.4.225.2
10.4.225.1 is the Gulf war to the ISP of the switch which I use as a jump on the switch.
VLAN 225 in which an Internet service provider is talk to internet, I want to only allow only udp to 10.4.223.2. IPS of rest should not go to the internet but vlan 224 and vlan 225 should access vlan 223.
I write access list, but it does not work
Subnet_Vlan223 extended IP access list
allow udp all 10.4.223.1 0.0.0.255 eq 53
refuse the host ip 10.4.225.1 10.4.224.3 0.0.0.252 - I want to 10.4.224.3 - 254 host must be prevented to communicate with 10.4.225.1
allow an ip
interface Vlan223
IP access-group Subnet_Vlan223 in
concerning
Sliman
The first IP address must be the source and the destination of the second. Since it is an inbound access list, your ACL look backward.
The deny statement may need to be written as two lines: permettre.2 to acces.1, refuse all the class C network to a.1

ACL lost after reboot of the switch
I have a Dell PowerConnect 5448. I created an acl using the CLI. I have telnet'ed in the switch and created and ACLs on port 19. This works well. He does his job and even after that I reload the switch (or the loss of power of the switch), the acl on the 19 port is never lost.
I now copy the same acl using the graphical interface, using a web browser - Dell OpenManage Switch Administrator for different ports. For example, I click on Switch - network - links ACL security. I can see the acl on port 19 I created using the cli interface. I use the web gui to copy this acl in a lot of different ports. "bind acl at interface" other ports on the switch. I save the changes. But, after I restart the switch (or lose power to the switch), these "copied" ACLs are lost. I still have the original acl I have created using the CLI, but lost the ones I copied to other ports by using the GUI.
Is this a normal behavior to lose these 'copied acl"using the web gui?
I never lose the acl that I created using the CLI, but after a loss to reboot or power, I always lose the acl that I copied using the web gui. Why? Am I missing a step?
Thanks in advance for any advice or suggestions!
By clicking on apply changes is just going to implement changes to the running configuration. To save the changes so that they remain after a reboot, the running configuration must be copied to the startup configuration.
See you soon.

What priority should I put in the QOS to work with IP voice service
I have a new router Cisco RV180W and don't know which priority should I put in the high, medium, low possibility of QOS
in order to work properly with the Ip voice device.
The default values are 61, 31 y 10 but in a net with 12 PCs
I think that this configuration 61 voice Ip and only 31 to the rest of the net
is a value that is too low. This is definition 2 VLANs.
How I can well criteria to configure these values of priorities?
In the previous (a WR210 of Cisco router), the only thing that was
set up which was the Ip voice connected in Lan 2 Port number with a high priority.
I'm stuck with this matter and it should resolve quickly
Thank you very much
Daniel Di Matteo
Hi Daniel, the claim of LAN should not affect the performance of the internet. All that is on the local interconnection, make queries on the local network will not use an internet connection. So as long as your servers/computers/cameras, etc. are using Cat6 cable and are all active GigE products, it will not be a large part of the review.
But for your connection internet, you may be correct. 4/1 connection is not much.
I need you to understand however, the WAN QoS for download speed only. Is not for download speed.
You can make the profile works in 2 ways. You can keep the amount of download speed to a device or you can ensure that a device does not take more than he should.
To set up a WAN profile correctly-
QoS-> WAN QoS profiles
Choose the maximum flow
Specify your bandwidth
Save
Back to WAN QoS profiles, at the bottom there is a WAN QoS profile table, click Add. In the drop-down list, select the priority. Set the minimum and maximum bandwidth, and then click Save.
Then you have to bound the profiles for the traffic selector. Go to QoS-> binding profile
There is a service drop down choose which desired protocol
Then choose the QOS profile you had a precedent set
The last part, choose the IP address you want to assign.
You can do this individually or in sequence. If you choose to be forbidden to use a device too download so that the beginning and the IP is the same. Conversely, if you have a range of devices, you can use their IP ranges if they are consecutive.
Apply the profile, restart the router.
I hope that I wrote this clearly for you.

Hello
Please don't get me wrong, but you should clarify this with Toshiba directly. Here on this forum, you can hear some useful opinions and comments, but I think you should get info straight from Toshiba directly.
You can also do is to contact the nearest Toshiba service provider and ask for help. You can visit ASP and demonstrate how it works and I hope that you will get a professional opinion on this problem.
Long ago I had a Tecra laptop with port replicator, and he was well in place and really does so port replicator he not there no danger of damage to the small port located in the lower corner.

Portege R500: external monitor does not work with the Port Replicator Port 2 and DVI
I have a Portege R500 running Vista with a slim Port Replicator II and digital monitor Viewsonic.
I connected the monitor to the DVI port on the port replicator and got it to work OK.
Press fn + F5 would switch between the computer screen and the external monitor.Then it stopped working, and I can't make it work at all. F5 recognizes just the laptop screen.
If I connect an analog display, it is fine, and I can pass between the two screens without difficulty.
The strangest thing is that, if I reboot when the Portege R500 is docked, the digital monitor begins by displaying the boot sequence, but then the signal is lost as soon as the screen stops the display of the progress (in low resolution) bar.
I spent an hour on the phone to support Friday, and he made me nowhere.
They finished by saying that he should never have worked! So what is the DVI port because then?Any ideas?
David
Connect your monitor directly to your laptop and see if it is recognized and you can go through FN + F5 between the two views.
If it works, then connect with port replicator, and then try again.It's probably best if you reinstall display drivers. Maybe there are new too on the download page.

Re: Tecra A10 - USB problem on the port replicator
I have a Tecra A10 and sometimes, when I work with her, the devices USB stopped responding if they are connected to the port replicator.
If I connect them to the laptop, they work fine.I tried to update the BIOS but now when I turn on the laptop it freezes when Toshiba red letters are displayed on the screen. I can work with the laptop properly deattached starting from port replicator.
Have you tried to load the default settings in the BIOS after the update?
If you have external devices connected to the laptop they remove and try again in the duplicator.
Maybe you should also update your laptop chip set driver. You can find them on the Toshiba site. -
Tecra A8: Problem with the USB printer connected to the Port Replicator III
Hi all
I have a problem with my Tecra A8, year Advanced Port Replicator III and a USB printer. With the printer connected to a USB port on the Port Replicator, I have to wait 2 minutes for printing to start. When it is connected directly to a USB port on the laptop and the laptop disconnected from the Port, printing starts immediately. I have the latest drivers from the Isensys of Canon LBP 2900 installed and Windows Vista professional as the operating system.
I called the technical support of my country, but her is not recorded similar problems.
A person with similar problem? Some help would be very appreciated.
Thanks in advance.
Hello
Seems like a strange question... Already done the standard procedure in the event of such errors? :)
The standard procedure is somehow similar to the following:
-Update your BIOS
-Update all the drivers for your machine
-Update your printer drivers
-Update your operating systemIf all else fails, then try an another Portrep if available, maybe you need to contact your dealer for an another portrep for the test.
Something like this should be your way. And then you sucessfully made a TROUBLESHOOTIN´ ;)
I'd be happy to hear feedback from you on your situation...

How to run the Xbox 360 via the port monitor on Qosmio G20
I just bought an Xbox 360 on eBay with a VGA cable which must connect the console directly to the port external monitor on my Qosmio, theoretically allowing me to use the screen on my laptop as screen for my video games.
I'm just a little worried that this port at the back of my Qosmio is technically to connect another monitor, not an input device, so it will work? And if so, how do I do?
I intend to spend a little time DIY autour with it when the console gets, but I guess it should be as simple hanging everything and then do it through media library or even simply initialize the TV itself rather than with the laptop everything?
Ideas, ideas, tips or advice (especially if you did before or know someone who has) would be appreciated.
A similar topic has already been discussed here in the forum. I recommend you research a bit.
