Cisco Firewall :: Access-List Traffic Control Attempting To Block RDP 3389

Nov 7, 2012

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?
 
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 3389
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 135
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 137
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 138
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 139
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 445
access-list 145 deny   tcp 192.168.30.0 0.0.0.255 10.187.10.0 0.0.0.255 eq 389
access-list 145 permit ip any any
 
ip access-group 145 out interface Internal
 
This work great on a 2821 Router, but not so much on the ASA.

Cisco :: Access Control List Practice Site?

Apr 25, 2013

I've been working on an application recently that practice ACL configuration, and since finishing I figured it should be put on the internet as there wasnt much more work to do to make it suitable for a website. It allows you to practice both standard and extended ACL configuration by generating a random number of ACL actions for you to configure, and provides the correct config to compare yours against to see if you were correct. It also emulates a router at a very basic level to allow practice when there is no equipment available.

Cisco :: Access Control List Not Behaving As Expected

Dec 18, 2011

I have an extended acl on my VLAN interface in bound and it is working like I need it to, securing one side of my network from the other allowing only what I want from my desktops to my servers. The acls look something like this:

vlan70 -----> inbound acl (allows 80/443) ---> vlan100

I need vlan100 to have access to something on vlan70 now and I cannot get it to work. My question is would this work?

vlan70 -----> inbound acl (allows 80/443) ---> vlan100
vlan100 <----- outbound acl (allows 9100) <---- vlan70

Traffic is initiated from vlan100 not from vlan70 then back through so an established rule does not work. Also there are many more ports open in my inbound acl but this is simplified for ease of reading.I want to make sure if I place both an inbound and outbound rule on my vlan and that it is in the right place, both on the same vlan.

Cisco :: AS5400 SIP Gateway And Access-list Control?

Feb 3, 2011

I have a sip gateway (AS5400) that is used to connect sip providers to our internal voice network.Internal gateway (10.1.1.2 LAN) -- SIP trunk -- AS5400 (10.1.1.3 LAN/ 8.23.23.43 WAN) -- SIP trunk -- Internet SIP Provider We encountered the following problem :A SIP call from internal gateway to the sip provider could establish but was muted on our side (sip provider could hear us)On the WAN interface of the AS5400, there is a ACL that filter traffic IN coming from SIP Provider

interface GigabitEthernet0/0
ip address 8.23.23.43 255.255.255.224
ip access-group 101 in

I log the deny on this ACL and I saw some udp packets denied with LAN addresses !*Mar 3 15:24:44.001: %SEC-6-IPACCESSLOGP: list 101 denied udp 10.1.1.3(0) -> 10.1.1.2 (0), 1 packet I did not bind anything on the sip config.When I changed the ACLs, calls went well.Why do I see LAN packets on the WAN interface ?

Dec 12, 2012

I am having some issues with creating an ACL for my gateway router.I want to block external access to my network 192.168.1.0/24 from internet so i set up the ACL on the WAN port of my 7200 router asI am using named extened access list -

{
deny ip any 192.168.1.0 0.0.0.255 log
permit ip any any
}
and i applied this inbound accesslist on the WAN port of router as
"ip access-group acl-in in"
 
Now i have blocked the external traffic to my network 192.168.1.0/24 but the issue i am having is i am also unable to reach outside now. All i want is to block external traffic on the router WAN port but allow internal traffic to outside. Did i miss anything in the access list?

Cisco Firewall :: ASA 5520 - Allow Traffic From DMZ To Internet And Block Traffic?

Apr 29, 2012

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?

Cisco Switching/Routing :: 3550 / Access List - Block One Ip Or Port

Jan 9, 2012

I have a layer 3 switch, 3550.I have several vlans on there just for playing around with. One of the vlans, has a vonage linksys box attached to it with a UK number attached. From time to time telemarketers call at 03:00 in the morning, this as I'm sure you can imagine is not much fun. The linksys box gets 192.168.3.3 as it's ip.The switch is connected to a non cisco router at 192.168.0.1
 
interface FastEthernet0/24
no switchport
ip address 192.168.0.2 255.255.255.0
 
I was thinking a time based access list would work best I have tried several variations but the phone still rings. I have tried access-list 1 deny host 192.168.3.3 permit ..... and more extensive lists but the phone still rings. I have not applied the time-range yet, so that's not the problem.I have applied the list to the vlan interface and to fa0/24 but it's not working.

Cisco Infrastructure :: ASA 3750 Firewall To Control Traffic Between VLANs

Jan 20, 2013

We have a data center with servers set up for different projects, some servers from partner companies and several small LANs. The traffic between all those needs to be controlled and firewalled. The servers and LANs are divided into different subnets and VLANs. Physically, their traffic is aggregated on a couple of 4506 and then sent to a FreeBSD server, where the logical gateways are set up and traffic is filtered between them.The BSD server is dying and having it there is incorrect in the first place, so we are planning to replace it with two ASA (5520) in failover.The question that arises is how to correctly implement firewalling between VLANs. Originally we thought to set up the firewalls in transparent mode and logically terminate VLANs on a stack of 3750 switches behind them, but would that filter the traffic between the VLANs? Then we thought to perhaps terminate the VLANs on the ASAs, use routing mode, and do filtering there, as well. Or should we implement multiple contexts? We have about 20 VLANs and all of them differ in rules of what should go there. None of this can be concidered an "inside" - trusted - zone, nor "outside". Internet and external links are connected and filtered in a different place.

Cisco WAN :: 6509 / Classify IS-IS Traffic With Access List?

May 16, 2012

I'm configuring Control Plane Police in a Catalyst 6509. This equipment is using IS-IS like its IGP routing protocol, and iBGP. In order to make CoPP work Im classifying the traffic entering the control plane like CRITICAL, IMPORTANT, NORMAL, UNDESIRABLE and DEFAULT. Obviously routing protocol traffic must be classified like CRITICAL. Doing so is easy to BGP because it runs over TCP/IP and I can configure the following access list to classify BGP:
 
ip access-list extended CP-CRITICAL-IN
remark #### CONTROL PLANE CRITICAL TRAFFIC INBOUND ####
remark #### ROUTING TRAFFIC - BGP ####
permit tcp host [BGP neighbor addr] eq bgp host [local BGP addr]
permit tcp host [BGP neighbor addr] host [local BGP addr] eq bgp
deny   ip any any
 
But IS-IS is also a CRITICAL traffic,  but IS-IS doesn't run over TCP/IP, rather it exchange its own PDUs. So, how do I classify IS-IS traffic with an access list?

Cisco WAN :: 2851 - VPN Traffic Not Captured By IPSec Access List

Aug 29, 2012

we have two 2851's.  One in Australia, one in NZ, IPsec VPN between the two.
 
We have multiple subnets behind the tunnels. From all the sunbets in Aus we can reach all the subnets in NZ, except for one.  From NZ we can reach all the subnets in Aus.  The traceroute and pings from the subnet in question in Aus goes out the internet interface of the router instead of going into the tunnel.
 
The subnets in question are 10.110.220/24 (Aus), 10.110.250/24 (NZ)
 
The access lists at both ends cover the traffic required but for some reason when leaving Australia the traffic is not captured by:
 
Crypto Map "AUS-SYD" 20 ipsec-isakmp
Description: Auckland VPN
Peer = 203.167.249.46

Cisco WAN :: 2811 Remove Access-list Applying To Inbound Traffic

Dec 25, 2012

I have been trying to figure out a NAT issue on my 2811 and the inspect engine.I have 'ip inspect FW out' on my outside interface. If I turn it off, I also have to remove the access-list applying to inbound traffic on that same interface. Why is that? This whole thing centered around SIP registrations from devices on my LAN to my provider. The provieder is showing that I am registering from a high end port (1024 or something crazy). He said that it sounds like some type of SIP ALG or something on my router. For the life of me, I can't figure out what would be causing it. I am just using a standard route-map that points to the outside interface using 'overload'.

Cisco Switching/Routing :: 4503 -MAC Access-list Extended To Only Allow Gateway Traffic

Nov 7, 2011

We have a gateway on a 4503, say on port 2/1, and we only want the other devices that are plugged into the 4503 to be able to talk to the gateway and thats it.  The other devices are Motorola TUT DSL devices and they plug into the 4503 directly.
 
Normally "switchport protected" would make this very easy to keep stuff on one port from talking to other ports but with 4500's you are not able to do that command.  So we implemented a MAC Access-List Extended ACL.  Here is what we did
 
mac access-list extended BLAH
permit #host 0000.XXXX.YYYY any
interface range fa 2/5 - 20
mac access-group BLAH out 
 
The MAC address 0000.XXXX.YYYY is the MAC address of the gateway that is plugged into Fa2/1 and the DSL TUT devices are plugged into ports Fa2/5-20.  We would think that this config would only allow devices on the TUT DSL to talk only to the Gateway but we don't really think this is happening.  The TUT devices are learning about MAC addresses that are on other TUT devices.
