Hi,
I still can't get my firewall working. I've tried doing it manually, i've
tried netconf (mandrake6), I've even tried things like mkfire etc. If
someone could help me I'd really apreciate it, I've read the howto over
and over but at the moment I'm just concerned with making my box secure.
There's been a lot of posts about people on my isp getting hacked. I'm
running 3PC's behind a Mandrake 6 box with two nic's in and a dial-up
connection with dial on demand.
My Linux box has eth0 which is 192.168.1.1 and eth1 which is 192.168.2.1,
my pc's are 192.168.1.2, 192.168.1.3, 192.168.1.4.
My dial-up is ppp0.
I want to allow any of my internal networks go anywhere.
I want to stop all external connections to my machine
post.mail.demon.co.uk needs to connect to my smtp port.
I have a static IP address 194.222.168.226
I run forwarding DNS for my local machines
I have ipchains installed and working
I need to masq all local connections headed over ppp0
I have my kernel compiled correctly
I just can't get the rules working properly. Anyone who can spend the time
helping will be very well thought of (don't have much else to offer i'm
afraid)
Thanks a million to anyone who can help
Andy
