The method I chose was create the group of logmein IPs (it changes as they add more) and then i applied the rules to the inside interface.ĭescription Hosts allowing use of logmein remote session software to local IPs Since the Logmein traffic originates from the inside by the client to one of the MANY servers you will need to block outbound TCP 80 and 443 traffic to those specific IPs related to. Hope this helps and let me know how you get on.Ī little late here and maybe my approack is a sledge hammer but it works for me ATM with our ASA and our PIX. Port 2002 needs to be open for TCP inbound and outbound traffic. If they can't resolve to logmmein, gotomypc they can't connect.Īnother way of doing this is to block installation of the executable such as logmien as a group policy or through your Anti-Virus software. Setup a local DNS zone on your DNS server Īnother easiest way to block any of these service without content filtering is by URL since you need to login to the, , etc. They already have a policy for companies who do not currently have GoToMyPC accounts but wish to block access using their Authorization Management Service, simply we have to send a request to the following email address. If you have a proxy server, you can use URL based filtering in that, if you need to block many more such websites.Īlso, GoToMyPC will help us to block our Internet-visible IPs. This will deny both tcp and udp connections to that ip. Using a simple outbound ACL will do the job, if you dont need any access to that site, you can just deny ip for that IPĪccess-list 100 deny ip 192.168.0.0 255.255.255.0 host 66.151.158.177 This will prevent anyone from starting a connection to access any computer inside our firewall. So to prevent the GoToMyPC broker from accessing our company’s computers is by blocking access to the host GoToMyPC Broker. GoToMyPC server always sends an outgoing HTTP "ping" to the GoToMyPC broker () at regular intervals checking to see if any connect requests have been received.

Read the following PDF document on this matter as well. You'll need to block port 8200, GoToMyPC generates only outgoing HTTP/TCP to ports 80,443 and/or port 8200 and you can also stop '' - sorry don't have the IP address but try doing nslookup for '' to get the relevant IP address. You could block access to to keep GoToMyPC from working.

You can also check Cisco IPS S387 SIGNATURE UPDATE DETAILS NEW SIGNATURESġ5454.0 LogMeIn Hamachi Activity atomic-ip informational falseġ5455.0 LogMeIn Product Activity atomic-ip low false If you want to find out who is using it you can build an access list around those two.Īccess-list 101 deny ip any host 66.151.158.177 logĪccess-list 101 deny ip any host 216.115.217.45 logĬheck your log files and it will tell you the internal IP addresses that tried to access those sites. This kills the constant polls that gotomypc uses in order to come back through your firewall. I just added two routes into my core router of You can block that IP from communicating to your network. LogMeIn application connects to an intermediate server () to establish communication. You could try blocking couple of LogMeIn ports (TCP 1296
So, the regex method may not be useful for that.

Note that IPS seems to be familiar with Hamachi:īlocking Log Me In & Go To MY PC LogMeIn uses HTTPS which is not covered in the HTTP inspection.
since gotomypc work on HTTP potential CSC would be a nice way to prohibit it. I'm not intemately familiar with those APPs. If you see these kind of applications has grown to hundreds (or used to grow) quite fast, faster then we're able to adjust regexp on ASA - since they are supposed to be static by nature. Regex _default_GoToMyPC-tunnel "machinekey" Regex _default_GoToMyPC-tunnel_2 "ercPoll" Match request uri regex _default_GoToMyPC-tunnel_2 Match request args regex _default_GoToMyPC-tunnel The ASA has built in REGEXPS for gotomypc and there was way to do this also for log me.Ĭlass-map type inspect http match-all _default_GoToMyPC-tunnel
