[FW1] encryption for FW-1 management

[Tony Wong]

What do I need to add to my rules in order to encrypt Fw-1 management service from my local Lan to my remote Site?   We already have a VPN tunnel running between 2 boxes on different networks. Http, telnet, ftp are all showing as encrypted between the two firewalls and LANs but FW-1 Management is not.   Any help appreciated
