LogMeIn and Firewalls

LogMeIn is compatible with all major security suites. Some configuration may be required to make LogMeIn work when the host is behind a firewall.

Important: If prompted, you must allow LogMeIn program files to communicate over the Internet for the service to function properly. For hardware firewalls, you must allow TCP port 443 traffic.
