Not Sure of Cause or Solution... let me know if you have any suggestions..
Upgraded from 5.0.7 to 5.2.3 and things went well I connected with the dialer... as soon as the connection was completed and comfirmed all computers on the local net were Locked out by the firewall...... Lock out is total and complete till disconnect dialer then all local connections restored... Help! I've since backsteped the system to 5.0.7 till the problem can be resolved!
