How can i create an top 10 list of the most popular website that users connect to through the ASA Firewall.
i have enabled HTTP inspect, and setup an Syslog server (S plunk), that collects all HTTP entries in the log, but i don't know how, to create an top list in s plunk.(don't if it is possible)
is there a better way to do this ? e.g. URL filter with web scene or IPS
I implemented access list on cisco 3560 switch but it never works. I want to block access from network B to Network A and allow from Ato B
Network A. 10.0.12.0/24
Network B 10.0.24.0/24
The configuration is
interface Vlan1

I want to send a particular data stream (source-A destination-B) through only one of two WAN routers to a remote site. The remote site also has two WAN routers. Traffic from source-A will travel through a core and distribution layer of 6500 L3 switches, running 12.2(33)SXH8, to the WAN routers which are two ASR1006s. The remote end is the same - two ASR1006 WAN routers to 6500 distribution and Core L3 switches. All 6500s are L3 uplinked to each other and to the WAN routers. All traffic from the local site to the remote site routes throuh only one of the two WAN routers. I want to move only traffic from source-A to source-B to the second WAN router to the remote site.
Would it be best to use policy-based routing or an offset list of some sort to accomplish this? I've done PBR before where you just hand off traffic described in an ACL to a particular outbound port and basically hand carry the traffic to a point in the network where EIGRP prefers the route you want.
Here's my setup:
- Cisco 1841 connected to the internet on fa0/1
- LAN connected to fa0/0/1 (switch port, connected to Vlan1)
On my LAN I have a web server that houses different websites. Those websites have DNS records that point to my public IP address, located on fa0/1. From the outside I can reach the websites perfectly, but I can't reach them from the inside. So it looks like I can't seem to connect from my local LAN address to the public ip address on the Cisco (who then should NAT it to the correct server)
Here is a snippet from my config:
--NAT--
ip nat inside source static tcp 192.168.0.3 80 interface FastEthernet0/1 80
ip nat inside source route-map Internet interface FastEthernet0/1 overload
--OUTSIDE INTERFACE--

I'm looking to implement a vlan filter to keep unnecessary stuff off my access-layer. Things like IPv6, IPX etc. I really only want IPv4, ARP and 802.1q on these 4500s. I know on 3750, 3560s etc, when I create the mac access-list, I can do it by ethertype, but on the 4500, I dont have that option.

I have an 1800 isr that is running with port forwarding only. It is running a series of ip nat inside source static address port address port commands. It does not have an access list bound to the outside interface. This is working fine, but i am wondering if this is a security concern?

Above is the network diagram and access list for VLAN 20 and VLAN 30, applied on incoming direction of each valn.But still able to access other port which is not on access list, tried changing the direction with no luck.Inter vlan routing is enabled on CoreSwitch default router is 192.168.10.10
i have one Cisco 3750, am using it as Core Switch where i have 6 more access switches are connected deirectly, and we are using VLANs in our network with the IP reange of 172.16.0.0 , now we had a new Internet connection which is dedicated to Exchange Server only.So we have TWO internet connection One for internet access to all users and another one for only Exchange Server.internet connection for the users is termiated at a Cisco 1700 Series Router and Internet for Exchage Server is terminated at a Cisco ASA Firewall.Now the problem is how can i write an access list, which says that all packets from Exchange server should be routed to ASA Firewall , and all other packets shoulde route to Cisco Router.IP address os Exchange server is 172.16.2.1, 172.16.2.2.

I created an extended access list as follows. Our network is the 10.10.x.x and the external addresses the PC needs to access is 11.1.x.x. Once this PC is rebooted, it is unable to access DHCP to get the needed IP address it bounces back to a 169.x.x.x address and stops working.
Extended IP access list 2000
permit tcp host 10.10.200.242 host 11.1.200.1 (gateway)

Then I applied the access-group 2000 on the interface the PC is connected to. What am I missing for DHCP to work and for this PC to always get the ip address that is reserved?
I'm trying to create a route-map for an EIGRP Distribute list on a N7K, the goal is to not advertise a 10.0.0.0/8 and 172.31.30.20/32 networks out a link to a remote site while permitting all other traffic to the internet (default). I configured the ACL/route-maps below and applied them outbound on the N7K interface but no subnets at all are being received on the remote site router.

[code] i.e. 1.1.1.1 will be used as the RP for 224 to 238 and 2.2.2.2 will be used as the RP for 239.Will that work correctly, i.e. if a source is trying to register with the router and its for the group 239.1.1.1, will it be denied against the first RP and then permitted against the second RP?

In my core Switch,there are 2 v LAN(V LAN 1 & V LAN 2)my switch is Cisco 4948,so be default ip routing is enable in it. My all servers (DHCP,HTTP,HTTPS) are in v LAN 1 & internet is also in v LAN 1.
My requirement is that v LAN 1 user should not communicate with the v LAN 2 and vice versa. But the v LAN 2 users need an access of all servers and internet which is in v LAN 1. How to configure the access-list. I have try on Packet tracer which i have attached.
note:v LAN 2 user should get the IP from dhcp server which is in vlan1.
If i fully populate all switch port (Cisco 3750 series) with 100 filter list on each port is it recommendable.

View 6 Replies View RelatedWe 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.

View 1 Replies View RelatedI have 3 3560 switches which are configured with trunks between them. They run vlan 10, 11 & 12. I have a 'core' switch (switch 1) of these 3 to which an MPLS router is connected on vlan12. I in addition have another switch hanging off the 'core' switch via a routed link (switch 4). I have EIGRP configured as a stub and as such the IP address on the routed link at the core switch end is of a /24 from v lan 1 on the other switch. This makes the route directly connected and therefore distributed via EIGRP stubs. Switch 1 is then exchanging routes with the MPLS router (via EIGRP).
The problem I have is that from any sub net on any switch (switch 1, 2 or 3) I can ping 192.168.13.1 (switch 4). When I try and ping switch 4 from over the MPLS I am unable to. If I trace to the switch I see it reaches the outside of the MPLS router, but is then unresponsive. The same applies if I try to ping switch 1 on 192.168.13.2. Any of the other IP addresses of switch 1 respond.
The MPLS network is a managed solution to which I have no access. I'm told that the MPLS provider is able to ping switch 1 & switch 4 on the 192.168.13.x addresses from a remote router (192.168.32.2). I have tried from a switch on the same L2 sub net (192.168.32.1) and I don't get a response.
From switch 4 I am able to ping the switch on 1 of it's interfaces (192.168.19.1), but not the interface I mentioned above 192.168.32.1. There are no access lists in place on the switches and no firewalls between the sites.
I have an internal server that is running DNS. I have that server configured to foward out to OpenDNS. I am using OpenDNS to do web filtering for my internal network. It looks as if the relay is not working in the router and that it is not fowarding those dns requests from my internal DNS server and out to openDNS. I have went back and added the name-server option for 208.67.220.220 and 208.67.222.222 (OpenDNS), but that has not fixed my problem.

Why the below configuration does not work? BGP exchanges routes without a problem all the time the distribute list is removed from the config. When I apply the distribute list it blocks all routes, not just those intended in the prefix list.
