Is this secure?
Today I'm using a NetGear router/firewall to secure my LAN. On the inside I have a number of clients and a fileserver which I access via SSH.
I am planning to reduce the pile of equipment and save some energy at the same time. To achive this I am thinking about having one single machine hosting both firewall and fileserver.
Using OpenBSD with PF and two network adapters this is of course techically possible, but is the solution equally secure as my current setup? I do not doubt that OpenBSD/PF is able to do a job even better than NetGear (if I set it up correctly) but what about having SSH-access from Internet directly into my firewall?
