I need to have either Telnet or SSH (preferably SSH) forwarded to a machine inside (IP 192.168.0.4) plus I need SSH to manage the FW from the inside from a different machine (192.168.0.1). I also need to open udp ports 2074 and 2075 as well as tcp ports 15425, 15426 and 15427 to the same machine for incoming connections. -Rob- _______________________________________________ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
