I have a VMware workstation on my host computer (windows 7) and the VMware workstation has a virtual machine (windows 7) on the host. We were trying to allow internet access only to the Virtual machine, i.e. to minimize exposure of the host to the internet. I tried to use Vlan Access Control list with MAC ACL to deny the host virtual machine from accessing the internet and allow all other traffic including the virtual machine. The configuration works for some time and after some time when the virtual machine continously pings the c3750 switch (wher the VACL is implemented), the host also pings the c3750 switch and re-establishes connection with the internet. But when we configured the c3750 switch to deny the VM and allow all other traffic, it works fine. It seems like the host automatically finds a way to get arround the VACL.
I'm using an ASA5505 (8.4(1)) and would like to block port 80 on a specific host in the LAN so machines in other remote LANs connected via VPN can't access this port on the host. Devices in the local LAN should have access to this port on the host. Here are the commands I'm using:
-access-list block_port extended deny tcp any host 10.20.10.20 eq 80 -access-list block_port extended permit ip any any -access-group block_port out interface inside
These commands are not working as I would expect them to. When I browse to http://10.20.10.20 from a remote machine over the VPN tunnel I am able to access the host web server.
I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.
I'm going through the CCNA training and I'm setting up my DHCP server on my 871 router. I have my cable modem into the WAN port on my router and have 1 host plugged directly into Fastethernet 1. I can ping any IP I want from the IOS prompt but I only have local access from the host. [code]
I test all devices using ping command, from ASA to router was fine (on both interface) but not to Host , and host to router was fine, but only on directly interface(F1/0), and to ASA was not success. am i miss something in my configuration?
configure my Cisco ASA5510 (asa version 8.3.1) so that one of the host (e.g.192.168.8.20) behind management interface can ping to the other host (e.g. 192.168.2.246) behind OUTSIDEinterface. I tried modifying the ACLs, NATs and ICMP statement, but still failed[CODE]
I have 2 web servers that replicate between them (two different internal ip). My idea is that if one of them will not work, the other to do the relay.I have a Cisco ASA 5505 I can do a nat for each machine. How should I set ?
I want to create a VPN between two PC's, (the server "Data" and "Remote Desktop" check the topology below), the Router Clabeck (cisco 2811 ) is connected to the internet through int f0/0 using a PPPoE connection and connects all the LAN PC's by PAT to the internet (you can see all the configurations in the Show Run below), the "Remote Desktop" is any PC with internet connection.
F0/1 F0/0 DATA--------------------SW-------------------ROUTER(Cisco 2811)---------------------INTERNET---------------REMOTE DESKTOP 192.168.1.51 192.168.1.254 201.122.53.177 192.168.1.1 Current configuration : 2116 bytes ! version 12.4 service timestamps debug datetime msec service timestamps log datetime msec
With my current setup on the 5508 controller, I don't have the ability to see any name resolution for wireless clients. I'm wondering if there is some way that I can enable this.
The reason I think this should be pretty easy is because if I enable the access point feature of a smart phone (Android or iPhone), when a client connects, it shows the client name on the smartphone. What's different about how a smartphone sees the wireless client and how WLC/WCS sees it?
Based on the configuration pasted below, we believe the host (10.0.2.200 / 255.255.255.0 GW: 10.0.2.1 with external DNS servers configured) should have access to the web. However, it cannot resolve any names nor can it connect outside.
I would like to have implementation of two ASA 5520 (in failover). Architecture Context
-The ASA are used as VPN concentrator only.In a first time ASA will be in charge to take in charge VPN IPSec Host-to-LAN connexion (with the IPSec VPN client) and I think VPN SSL anyconnect client will be setup in a near futur.
-We must define two categories of users (student and researcher), for each one we want define : + An IP address pool + ACL + Split Tunneling (only LAN traffic will go in the VPN tunnel)
-The ASA will perform authentification via RADIUS server (the radius server is linked with a LDAP server) + In the RADIUS server we want define the category of user (each one user is a student or a researcher)
-The VPN clients use the internal DNS to request LAN ressources.
-A timeout of the VPN if no traffic during 60 minutes
-The VPN user perform authentification with PSK (no certificate)
the RADIUS server software is IETF compatible (url...)The architecture is the following :
-One internet connexion -A corporate firewall with 3 DMZ : + 1 DMZ Public ; which is connected the ASA "outside" interface (encrypted traffic) + 1 DMZ Private ; which is connected the ASA "inside" interface (uncrypted traffic) + 1 DMZ LAN ; there is some VLANs routed by 6500 routers. -On the LAN there is the radius servers -On the corporate firewall : +The https and ipsec will be opened between the internet and the ASA +The RADIUS traffic between ASA and the radius servers and the traffic between the pool VPN users and the LAN.
Ive been going over some exam questions and i got a question regarding diskless host. i have dont some googling but cannot find a overview explanation.
I am trying to find a way to find the netid and hostid of any given ip address, given any ip address, I know the left side the IP address is the netid and the right side of the ip address is the host id but I am pretty sure there is more to it than that.
What are the most common cause for a "could not connect to host" problem?The firewall is not blocking anything, and even with the firewall disabled, the problem still occurs. With "Server" service turned on, the problem still happens.Windows xplso the server couldn't find any trace of a connection attempt, so my attempts to connect never actually made it to the server.
Any service where a computer can host a website just about anywhere with an internet connection? As in... using the VPN as the connection so that no router port forwarding is needed?
I thought that in the past I had problems with my ASA5505 because I had to reboot a number of times, now that I have logging enabled I can see the following: -Deny traffic for protocol 17 src inside, licensed host limit of 10 exceeded.Does this mean that I can not have any more than 10 inside host going out of the outside interface at any time, if not what this means and how I can solve it.
I've got an 1841 router acting as the firewall for a LAN. It also does NAT and acts as the dialer for a PPPoE DSL line to the internet.
All is working fine, except now I need to allow a Tivo device to connect to certain ports on the Tivo servers on the internet. I want only the Tivo to be able to do this. The problem is that NAT is happening before my outbound ACL is checked, so even though I've got rules to allow the Tivo's LAN address out on all ports, it never works. I've verified this using a syslog server, and can see my external DSL IP trying to connect to the Tivo servers and being denied.
I've done things like this at work by NATting the appropriate internal host to its own external static IP address, which allows me to write rules allowing only that external address to do stuff. But I don't have multiple external addresses to work with here.
I tried applying my outbound ACL to the LAN interface of the router in the "in" direction (and removing the same ACL from the Dialer interface in the "out" direction), but that broke other things like the router's own ability to ping out to the LAN or to see a TFTP server on the LAN. I could maybe fix all of that with rule changes and inspect statements on traffic going out toward the LAN (not sure of this, think so), but I'm wondering:
Is there a better way to let just the Tivo makes outgoing connections to certain ports?

If we have the following setup:Host A (IP :192.168.1.1, Prefix/length : 24, GW : 192.168.1.254) connected to the Router A on int Fa0/1 (IP : 192.168.1.254), Router A is connected to Router B, Host B (IP :192.168.2.1, Prefix/length : 24, GW : 192.168.2.254),connected to Router B on int Fa0/1 (IP : 192.168.2.254).Using the mentioned setup, after Host A pings Host B successfully, which entry will be in the ARP cache of Host A to support the transmission ?.
I got one request from one of the user to allow his ip to access one public using port www, this needs to be allowed in Cisco PIX, if the below command is correct for this.
Source host : 10.84.11.1 Destination IP : 203.126.112.131 Port : www
Problem Host A unable to reach Host B, trace route from Host A it reach to Router B but the packet unable reach to the Host B here the 1st level troubleshoot I did
1. Traceroute and ping success from router A to host B
2. Ping success from router B to host B success
I wonder the packet reach to router B but it didnt pass to Host B.
I have an issue with NAT on a Cisco 1841. See following configuration,
interface FastEthernet0/0 description Connection to LAN bandwidth 100000 ip address 10.90.0.100 255.255.0.0 ip helper-address 10.100.2.2 ip helper-address 10.100.2.3 ip load-sharing per-packet ip nbar protocol-discovery ip nat inside ip virtual-reassembly duplex auto speed auto

I've tried this with both a source list NAT statement, and a route-map. The router can contact hosts on the Internet:
Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 128.31.0.51, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 144/147/148 ms
While running the install wizard of soft appliance LMS 4.1 it asks for hostname and also the domain during the install. Is the hostname suppose to be fully qualified domain name exp: foo.blah.com or just hostname without fqdn exp: foo? Reason why I ask is when I ran the following command below in the shell it doesn't look like it is setup correctly. Also if I did the install without my hostname in dns first will this mess up my install?
What is the best way to isolate hosts on WiFi network managed with 4400 controllers so they only see def gw but not each other, something like "switchport protected" but for WiFi ....
I have a cisco ASR 1002 I have plugged a host into an addressed port and the port comes up however the host cannot ping the router and the router cannot ping the host. Neither can router ping its self. I do the same on a cisco 2800 router and it works fine. What's goin on. Is it the fact that this is a ASR router ?
I have 2 SSIDs on WLCs.I would like to have 1 SSID point to the acs radius using LDAP store and the 2nd SSID point to the acs radius using the host identity store for mac filtering.both scenarios are working, but not together.if I adjust the rule order I can get one SSID, but then the other fails. [code] It seems to me that there should be a simple process to make this happens. I thought if the rule is not matched it would move on to the next rule etc.I might be able to live with first checking ldap and if that fails move on to the local host db, but that seems ineficient. url...
Currently, we allow /24 into our DMZ as follow: [code] Now, if we need to extended the /24 to a bigger scope ( range of 15 class C networks ) : can I just re-used the static route or should I use a ACL to allow traffic? This is on a ASA5585
I have set up our network with an RV220W as gateway/Wifi-AP,VPN host.I am able to connect over the WWW with the windows 7 client laptops no problem, BUT ,I cannot from my office reach out to the laptops, it seems as if the tunnel is one way.The users can do anything they need, but I want to be able to connect to them to update their AVG or render remote assistance etc.Ping from client to home network no problem.Client laptop is invisible to any ping etc FROM the home network.
