Please anyone can help us with the following question?
We want to deploy Openfire Server in our corporate network, but we want remote users working out of the office also connect to IM Server. We have the option os installing VPN software to this users, the other option is a NAT in our firewall and connect without VPN Software. I don´t like very much this last option, for security conerns, but is the option users are used to now. If we open the port, is there any way to enforce security, placing some kind of gateway in a DMZ, or some thing like that?
Best regards and thanks in advance,
