Cisco extended ACL

Hi, I need help! On one VLAN specific, I want to give my users wifi access to the internet and to the specificities of the resources on the local network. I create and extended ACLs on my Cisco 3750 and apply tone my interface VLAN. It looks like this:

10 ip allow any 10.4.197.0 0.0.0.255--> my subnet for wifi users

20 ip allow any host 10.4.134.2

30 ip allow any host 10.4.134.3

40 ip allow any host 10.4.134.16

50 ip allow any host 10.4.134.117

60 ip enable any 192.168.0.0 0.0.0.255--> my DMZ

100 ip allow any 192.168.133.0 0.0.0.255--> my firewall subnet

on my interface vlan, the command is: ip access-group ACCESS in

My problem is: I can only access the hosts on my lan I've specified (it is perfect), but when I try to go on the internet I can not!

Does anyone have and idea to solve my problem? I try to put another ACL:

Extend the ACCESSWEB IP access list

10 permit tcp 10.4.197.0 0.0.0.255 any eq www

and apply it to my interface vlan (ip access-group ACCESSWEB on) with the other (ip access-group CSDDSF in) but the result is the same (not Dansnternet). If I put just this one (ip access-group CSDDSF in) internet works fine.

Thank you!

Collin has done to identify the problem that DNS is necessary. I am surprised that he did not see the other part of the problem. Your access list allows destinations host specific and 2 subnets. Don't forget that in each access list, it is implicitly denied any one at the bottom of the access list. So when you try to access the Internet access list check your packet against the access list. It does not match any of the permit and if it is rejected.

To achieve the desired results in that access list should follow the permit that you created with deny statements that deny all network destinations that are inside your network and then has a permit ip any one for traffic can access the Internet.

Extended ACL works in both directions?

Hello

I would like to know the following, and hopefully one of you can help me:

If I request an extended ACL that PC1 must not communicate with PC2 and apply to an interface of output like this:

Cisco(config-ACL-whatever) #-host pc1 pc2 host extended ip access list

.. is it still possible for PC2 start for example a telnet to PC1 session?

IOS ACL are not stateful, except if you use CBAC (IOS Firewall). Which means:

1. your ACL will block the origination of traffic du.1 a.2

2 hote.2 can come from communication a.1, du.1.2 response packets are blocked, so no tcp sessions can be set up. Stateless protocols that use udp and don't expect answers could work-.2 could syslog a.1, for example

Extended ACL problem

I have a question, I am doing an ACL extended to deny HTTP, Telnet, and FTP internet traffic to PC1 in an exercise that I do.

I did the ACL following and applied to the loopback interface on R2 (where the ISP is the 'cloud') PC1 is connected to R1 that is obviously connected to R2.

IP-access-list scope ACL_TCP

TCP 209.165.200.160 refuse 0.0.0.31 10.0.0.0 0.0.0.127 put in place

allow tcp any a Workbench

Is there a better way to do it? This ACL scope works for my purpose?

Tell R2 address is 192.168.1.2, and you only want to allow this address. You create the acl on R1 and R3, and they would look like:

R1: 192.168.1.1

R3: 192.168.1.3

access-list 23 allow host 192.168.1.2

You can apply this to your line on R1 and R3:

line vty 0 4

access-class 23 in

named extended ACL doesn't work, can you help me?

The camera I used is 2651xm router and NAT is used to connect my everything inside the LAN (192.168.1.x) to outside internet. A standard ACL was used to block some local host access outside the internet, and it worked fine. My question is, when I created a named ACL extended and apply it to the interface that is attached to the LAN, entire local network will not be able to access the internet outside! can you give me some advice?

My hardware and software is 2651xm + IOS 12.3(6b)

The best regards.

Jan

Hi Jan,

I think the problem here is that you are confusing the use of an access list to control the SENATE, with the use of an access list to filter traffic.

Looking at the NAT, I see you have ip nat inside source list 1 pool cisco2651-natpool-168 of overload. This means that you still need to access list 1 to define which source addresses are translated. You could, I guess, use a named access list to do this, and the order would be something like ip nat inside source list of people inside outside pool cisco2651-natpool-168 overload, where the people inside of the country is the name of a standard named access list. But no matter how you play, you still need to access list. Try to put back the access list 1, and you will see that it will start working again. Note that the access list used to control NAT must be a-list type , named or numbered, not a scope.

On the other hand, you used the named acl test scope list to filter your traffic, and that's fine. OK, the list is wide open at the moment, but I guess you want to restrict later.

I hope this helps. Write back and let us know how you go.

What is is it possible to use the acl extended for split tunneling on ASA?

I'm setting up VPN IPSEC RA on SAA and I would like to know if it is possible to use the ACL extended as part of the split tunneling?

Thank you!

Yes, you can use the extended ACL. See this example:http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-nex...

ACL router and Switch

Hello.

I have a small question.

I implemented a simple extended ACL.

ip licensing 10.10.10.0 0.0.0.255 192.168.1.0 0.0.0.255

refuse an entire ip

It is enabled on the SVI interface IN direction with ip 10.10.10.1/24.

When I test with the ping from the router to a network blocked from using the interface (SVI) source ACL does not work.

Example: ping source 172.16.1.5 10.10.10.1 = success.

This should not be blocked and only allow traffic to 192.168.1.0/24?

So my questions. The ACL effect on the interface of the router itself and only other hosts on the subnet / vlan? (I think I remember having read about it, but can't find it)

Thank you.

Hi traffic there, navigate the interface so that the ACL to be considered. Here is a link to another thread on the forum that explains this very well:

https://supportforums.Cisco.com/discussion/12043016/pls-explain-SVI-ACL-source-and-destination-direction

I hope this helps!

Thank you for evaluating useful messages!

Pls explain the sense of source and destination SVI ACL

Hi I have a home network up and well running that uses a Cisco 1801.

I'm just trying to increase my understanding of some is the config and I'm confused by ACL on an interface VLAN.

OK so I "be the router" and imagine packets flowing to me and me

I have two VLAN configured

VLAN 10 - 10.10.10.0 / 25

VLAN 20 - 10.10.10.128/27

So, for example, one of my Virtual Machines has the address of 10.10.10.6 and is on VLAN 10.

Another is the 10.10.10.134 address and VLAN 20.

I want to allow 10.10.10.6 Access 10.10.10.134, but keep the other VLAN 10 access devices.

So I create an ACL and apply it to interface Vlan 20 entrants.

The configuration below works as you want, but I don't understand why.

If packet filtering is for the incoming direction of the interface, then my logic would state that the source address of the packet filter would be 10.10.10.6, not 10.10.10.134.

Can someone help me understand. Thank you.

interface Vlan20

ip access-group ACL-INBOUND in

ip access-list extended ACL-INBOUND

permit ip host 10.10.10.134 host 10.10.10.6 log-input

That is to say, a vlan SVI is no different from a physical interface with respect to an acl.

to apply an acl entering traffic control devices SVI in this vlan

apply an acl Outbound IVR auxdispositifs controls traffic to that vlan

I want to allow 10.10.10.6 Access 10.10.10.134, but keep the other VLAN 10 access devices.

access-list 101 permit ip host 10.10.10.6 10.10.10.134

access-list 101 deny ip 10.10.10.0 0.0.0.127 host 10.10.10.134

access list 101 ip allow a whole

int vlan 10

IP access-group 101 in

the acl above allows 10.10.10.6 to talk to 10.10.10.134 but blocks all other 10.10.10.x/25 customers to talk to 10.10.10.134. Then, it allows customers to 10.10.10.x/25 to talk to everything else. Note You can not only "permit ip any any" at the end, but you will want to probably other lines permit while I have included a general all allow.

I hope you see it's the same concept applies an acl to a physical interface in terms of incoming and outgoing traffic. Whence came the confusion was probably that you have applied the acl to vlan 20 then he effectively blocked the return circulation and not the original packet from to vlan 10.

It is usually best to filter packets to their source.

ALS IP Cisco 2901 and POLITICS with dual gateways LAN-based ROUTING

Hello

I am configuring a failover solution combined with the ACB using two bridges already configured. See the attached diagram.

I currently have two ASA 5505 and a 2901.

According to the example: http://www.firewall.cx/cisco-technical-knowledgebase/cisco-routers/861-c... I've set up the following in the 2901:

I did some tests and the part of failover seems to work but the configuration of the ACB does not work as expected. Only thing missing track 1 each time delivering properly and trak 2 is declining.

Any help clarifying the feasibility and practicality of this configuration is greatly appreciated.

Dan

Adding a value of AD won't fix ACB (sorry if I gave that impression).

On the client that you are testing with can you look it's the example routing table ' netstat - nr ' example and see what it shows in terms of gateways.

It can be that you want to debug your routing policy to see what is happening on the router.

I think that you made a mistake with your ACL name. the ACL applied is "VPN-ACL-SPLIT" which is an empty ACL. You must switch to that of "ACL-VPN-SPLIT" that has the entry "ip 192.168.1.0 allow 0.0.0.255 192.168.1.0 0.0.0.255" inside.

Internet only access ACL (not answer)

Hello

We have a new WLC set up in a remote desktop control 4 access points and must restrict access to our comments of SSID only internet access. It's the way the network is currently configured:

3750G Switch:

Two VLAN for layer 3, one for the inside network and internet access company and one guest access to the internet only. These two have addresses for assistance on them pointing to our DHCP server that has extended for comments and the Corporate VLAN. The controller is located in a trunk port with an address on our subnet management and the AP on access on the same subnet for management ports. Subnets are as follows:

10.80.27.0 - wireless Corporate (vlan 27)

10.80.28.0 - Wireless comments (vlan 28)

10.80.10.0 - management (vlan 10)

(In addition, we have several other VLANs on a 172.16.0.0/16 and the 10.80.X.0/24 network)

To limit access to clients without comment thread, I tried to add the following ACL on vlan 28 thinking this would allow requests DHCP and DNS for wireless and web access clients while denying access to others within the network resources:

IP extended ACL UNTRUSTED access list

permit udp 10.80.28.0 0.0.0.255 any eq area

deny ip 10.80.28.0 0.0.0.255 172.16.0.0 0.0.255.255

So basically, without applied ACL, a customer receives an address from the DHCP server without problem and is able to surf on the internet as well as all inside resources. When I apply the ACL to the VLANs, customers can no longer receive an IP address from the DHCP server. However, if a customer had already received an address before the application of the ACL, that the customer is able to navigate while being denied access to the network when the ACL is applied. Which is the desired effect. It seems that the problem is access to the DHCP server when the ACL is in place. Is misconfigured my ACL or I go just about it entirely the wrong way?

(my apologies for the too wordy explanation, wanted to make sure I had enough detail in there)

I had a problem like this before.

I shared my bootps / bootpc in each for his own line and it started working

Something like

Note DHCP server

permit udp 10.80.28.0 0.0.0.255 eq bootpc host

permit udp 10.80.28.0 0.0.0.255 eq bootps host

What if you add the log after deny it. Logs show something? Send to a syslog might help filtering

ACL problem.

Hello everyone, for some reason any with this workshop of tracer of package I get the last piece of ACL incorrect.

This is the lab I've done so far (94%)

http://www.sendspace.com/file/gsnk07

They ask the following

Configure the standard named ACL on the vty lines R1 and R3, allowing the hosts directly connected to their Fast Ethernet subnets for Telnet access. Deny explicitly all other connection attempts. Name these ACLs VTY-Local standard.

They also ask that for the extended ACL

Name of the block of the ACL.

Ban traffic from the LAN R1 to reach the R3 LAN.

Ban traffic from the R3 LAN to LAN of R1.

Allow any other traffic.

Here's what I have on the Router 1 for the standard ACL

IP access-list standard VTY-Local

deny 10.1.0.0 0.0.0.3

deny 10.3.0.0 0.0.0.3

deny 10.3.1.0 0.0.0.255

10.1.1.1 permit 0.0.0.255

I couldn't understand why my ACL is incorrect.

Host 1 IP (connected to R1 ip host) - 10.1.1.1

Connecting series between R1 and R2 ip subnet is

10.1.0.0 30

East of R2 to R3

10.3.0.0 / 30

Host 2 to R2

10.3.1.0 24

2 host address is 10.3.1.1/24

Can someone help me?

deny 10.1.0.0 0.0.0.3 - corresponds to the IP 10.1.0.x

deny 10.3.0.0 0.0.0.3 - corresponds to the IP 10.3.0.x

deny 10.3.1.0 0.0.0.255 - corresponds to the IP 10.3.1.x

10.1.1.1 permit 0.0.0.255 - match IP 10.1.1.0

ACL must be correct: -.

deny 10.1.0.0 0.0.0.3

deny 10.3.0.0 0.0.0.3

deny 10.3.1.0 0.0.0.255

10.1.1.1 permit 0.0.0.0

or

10.1.1.1 permit 0.0.0.0

all refuse

REQUIRED: ISE 1.1.3 Posture Setup and Config Switch (ACL, dACL)

Hello

anyone could please posture ISE configuration screenshot (and sanitation)

I need urgently a DACL and a redirect ACL who work at least in a laboratory of the model.

Political authentication and authorization is not necessary.

policies of posture and sanitation is not necessary.

The question is ACLs (I guess)

It must be a valid switch configuration file, with ACL (if necessary) an ethernet DOT1x port.

My IOS is 122.55 SE or 52 SE

Thank you in advance.

Best regards.

C.

SSH specific IP access

Hello

I have configured 10 interface vlan on my cisco 6509 switch.

However, I want my SSH users on IP management only. SSH access on other PIS (defined for each interface vlan) should be blocked by the switch.

Please suggest how to configure it.

Thanks in advance.

The best way to achieve this is to bind an access list to your vty line. This access list is normally a standard ACL, but this time you use an extended ACL that uses your IP management as a destination:

EDIT: No, it doesn't work as proposed. Please see the other posts.

MGMT-TRAFFIC extended IP access list

permit tcp SOURCE-NET host 10.10.10.10 eq 22

line vty 0 4

access-class MGMT-TRAFFIC

In this example, SOURCE-NET is the IP network hence your traffic management comes and 10.10.10.10 is managing IP on your device.

AnyConnect VPN setup problem

Hi all, I'm going to have bad configure anyconnect VPN on my router. I'm CCENT pre level and especially followed a tutorial, but feel I'm missing something simple here.

It's a fairly simple installation on a Cisco No. 2851 - faces of a single interface my LAN 192.168.1.0/24, the other has a public IP address.

I created a network 192.168.2.0/24 VPN users, mainly to have phones Android connection of their mobile phone networks, and have access to the servers/security cameras/etc by using their local IP addresses. When my phone connects, it gets an IP address and is connected, but is not communicating with my LAN correctly.

The VPN client can ping 192.168.1.254 (the router's LAN IP) - but not the other devices on the network. However, the devices on my LAN can ping the VPN clients to their address 192.168.2.x.

Here's a copy of my current config, I have reorganized some elements with #s. Also pasted my ip sh road under him. Do not forget that I am a novice, please forgive the hack :)
