I'm trying to set up a simple firewall/router, but I seem to be having
some difficulties, so it is time for me to ask the gurus. This is what
I have to work with:
|far hosts|---|Router|---|Internet|---|Router|---|Linux
RTR/FW|---|switch|---|near host|
eth0 eth1 eth0
Linux Router/Firewall:
eth0: 159.139.95.14/255.255.0.0
eth1: 192.168.175.1/255.255.255.0
near host: 159.139.95.1/255.255.0.0
far hosts: 129.176.138.161 and 129.176.140.37
router eth0: 192.168.175.25/255.255.255.0
This routing setup works just fine in this configuration (all the
routing tables are correct), but now I want to limit the access coming
in from the internet
I want anyone on the internal host network (159.139.0.0/255.255.0.0) to
be able to connect to the two far hosts, to any of the 192.168.175.0
addresses with any protocol. I want the far hosts (and only the far
hosts coming through the firewall) to only be able to connect to the
near host with any protocol.
I thought it was going to be simple, but I have been bashing my head
against it for a week....
Thanks in advance.
