Block All Internet Traffic On One Network Computer?
Jul 5, 2011
I have a computer on my network I would like to use for media streaming. I would like to block all incoming/outgoing internet traffic and keep all network traffic on this computer local. Is this even possible? Can I also easily restore it if necessary? The computer is running Windows 7.

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?

how to block a user from using the internet when they plug their computer into a router. My roommate has refused to pay her share of the internet and, being a college student, I don't have enough money where I feel generous enough to let her have free internet after stiffing me. Basically, I have 2 routers at the moment (hoping to fix this soon): my Qwest modem works as a router but I also have a Linksys router connected to it. The only phone jack is in her room so I have no way of stopping her from plugging her computer straight into the modem and/or router. I've configured the wireless so that she would be unable to access the, wirelessly but I'd like to know how to prevent her accessing the internet when she plugs her computer directly into either component.

I am attempting to block all FTP traffic on port 21 from the servers in my network, and only allow FTP from one server to go out.
I have created the following ACL
access-list 101 Permit ip any any
access-list 101 Permit 21 1.1.1.1 0.0.0.0 any
access-list 101 Deny 21 any any
and have applied it to my truck VPN that goes up to my firewall
int Vlanxxx
ip access-group 101 out
But when i test ftp is still allowed by all servers.

I have a Cisco C3560CG which is running C3560c405ex-UNIVERSALK9-M), Version 12.2(55)EX2.The switch has vlan 1 and vlan 50 configured, vlan 50 should have access to a limited number of host in vlan 1.The following acl has been applied on the inbound to vlan 50:
10 permit tcp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq 137 138 139 445
20 permit udp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq netbios-ns netbios-dgm netbios-ss 445
25 permit icmp 10.16.30.0 0.0.0.255 host 192.168.1.243
26 permit ip 10.16.30.0 0.0.0.255 host 10.16.30.254
30 permit ip 10.16.30.0 0.0.0.255 host 192.168.15.254
[code]....
I sure the above would work, but for some reason some of the packet counter are not incrementing but the traffic is being blocked. But I would like to see the counter increment.Also I have that I may beed to use VACL wouls this be the case?

I have configured my e4200 to block traffic at certian times uses both the Parental Controls and the Intenet Access Polices. Neither one seems to work though. [code] I have the same MAC addresses specified in each rule. Initally I had only the first two rules. Those didn't work, so I added rule 3 and 4 (they do the same thing as rules 1 and 2 but from the opposite direction). There are no compliaints, but they don't stop any traffic.
I started with the Parental Controls, they didn't work either. The page in there that lets you pick which machines you want to block seemed next to worthless. I have about four rows listed as "Network Device." REALLY LAME! As the MAC addresses are accesible and these weren't working I went to the IAP.

I click save and get this pop-up: Incorrect source ip address. Invalid format of the start IP address. Current Firmware Version : 2.11 The ip is obviously valid, what should I do?

where is the best place to block unwanted traffic? By that I mean, should I block it at the router, firewall, IPS? As an example, I'm dealing with DNS flood attacks - probably DDoS and reflection. I have a pair of Cisco 2821 routers with two different ISPs doing BGP. Behind that I have an ASA 5510 with IPS module. Behind that I have 2 public DNS servers. Over the last few days I've seen an increase in bogus DNS queries - high volume, distributed. My question is where is the best place to put the ACL to block them? I've been putting them on the ASA, but when the attack is running, it jacks the CPU to 60%. If I don't put the ACL, the IPS seems to pick them up after a while and the CPU is almost as high as with the ACL. I haven't tried to put the ACL on the routers.

Is it possible with a 3560 to block all traffic to a certain vlan except for one or two IP addresses? Create an ACL or something? We have a vlan for voice calls (SIP) and we are getting a lot of scnas that are making the phones ring and such, and I think we can stop this if we only allow traffic onto the vlan from the IP's the SIP traffic is SUPPOSED to be coming from.

I have a working L2L between two locations. Location A and Location B.
Location A: 172.16.16.0/24
Location B: 192.168.0.0/24
I would like to block anything inbound to Location A from Location B that isn't initiated from Location A. The block should be done on the ASA5505 at Location A. Location B uses an ISR G2 router. i.e. Location A can start an SSH session to a server in Location B Location B cannot start an SSH session to a server in Location. .
I tried using a VPN filter on the ASA5505 but it isn't stateful, I cannot pass any traffic when using it.
Config on my ASA:
access-list vpn-traffic extended permit ip 172.16.16.0 255.255.255.0 192.168.0.0 255.255.255.0
access-list block-vpn-to-local extended deny ip 192.168.0.0 255.255.255.0 172.16.16.0
[Code]....
I also have an AnyConnect VPN setup for the ASA5505 and it is running 8.2(5).

if the firewall rules in the RVL200 work for inter LAN routing as well as LAN<->WAN? I need 2 separate networks in a house, 1 for business 1 for family, and I want to only allow my IP on network 1 (family net,10.0.0.0/24) access to network 2 (business net 10.0.1.0/24). I want this as if I change rooms were a access point for business is not available I can use the home net and specific IP to access certain business net IPs. I saw you can turn inter vlan routing on or off, but it wasn't clear on firewall rules.know of a similar router in cost but with gige instead of 100Mb ports?

I need to block incoming traffic with Dlink DIR 600. I know how to create the rule source (WAN) to destination (LAN) to deny all protocols. But what IP will I put in WAN? IP address of my Internet? Or how can I enter the ALL IP range in source...format for the IP (it's not 0.0.0.0).
I want to do this because in the DIR log section I'm being PING Flooded. I already un-check "Enable WAN Ping Response" but still receiving the message.
