How save is HfSql opening portforwarding (4 replies)

Hello to you all,

We want to switch from filesharing to HfSql. Because people want mobile apps.
Has somebody experience wih safety issues. Because we have to open a port (normally 4900) and forward it to a pc (single user) or server.

I have read PcSofts info: [help.windev.com]

What to do (extra)? Hardware / software?

Thanks in advance.
