Dear List members
I want to put a firewall between a particular Unix box and the rest of
the college network.
I have a 'spare' 166 pentium pc with two network cards & 2gb hard
disk.
I want to do is prevent all access except for the following
circumstances.
1 The workstation making the request is from a small selection
known ip addresses for full access to the unix box.
2 Its web access from a larger range of know ip addresses.
I have tried Smoothwall but I could not understand how it filtered
source IP addresses. I SEEMED to me that you could filter on
source port address let it through to a destination & port addresses.
If i understood this correctly, for example, TCP it would be let
through to a particular IP address & port BUT it could be from any
source address. I want to say that (as i can on a cisco router) that
I won't entertain it is its not on the 'list' and reject it.
Two questions.
1) Have I totally misunderstood the smoothwall system?
2) what would list members recommend to allow the PC to do the
job I require.
By the way I want a physical firewall rather than using the
Access.deny/access.allow files as it keeps 'them' that one step
away from the system.
Any help appreciated.
Regards
