Re: Redhat 8.0 networking/routing/security issue...

["Hendra Santosa" <hendra () srd co id>]

It's possible to have the one Linux box as the proxy and also as a firewall
to secure the two other boxes. It's fine whether you used one NIC or two
NICs but it would be better to use two NICs on your proxy.
Apply several conditions to secure your proxy like shutting down your unused
services, delete unused users, blablabla.
Activate masquerading on your proxy like as follows:
for a in /proc/sys/net/ipv4/conf/*/forwarding

do echo "1" > $a

done


Install proxy application (e.g. squid) and apply your rule there.

I'm wondering if the person from your ISP really understand about what
he/she said or not :)
