We are using AS/400 V4R5 server in our office and we have an application running on it. Right now we connected some other users (5 members) of this application who is outside from our office through VPN. But now our management asking us to provide support for more than 25 people (this may increase).
From our-side we are thinking that, to put router on all user side will make big work and also high cost consuming. So we planned to offer this service by assign static IP to our AS/400 server.
So I need some idea from you guys. Whether is it a good thing to assign Static IP?
And if we do this what are the steps to be taken in terms of security on AS/400?
If you have any other options for this solution please let me know.
