You will have to make a WSPCFG.INI file in the PcAnywhere directory if you wanne use the firewall-client. It looks like this : [AwRem32] NameResolutionForLocalhost=P ;LocalBindTcpPorts=5632 RemoteBindTcpPorts=5632 RemoteBindUdpPorts=5631 ;LocalBindUdpPorts=5631 KillOldSession=1 [AwHost32] NameResolutionForLocalhost=P ServerBindTcpPorts=5632 ServerBindUdpPorts=5631 ;LocalBindTcpPorts=65300 KillOldSession=1 Persistent=1 This WSPCFG.ini file will tell ISA what to do when the program comes active. To check whether it works, start a host session and choose 'display status'. It should read 'waiting for connection on <internal IP> & <external ISA ip>. If not ... you've got troubles. I hope it helped. Frederik
