Firewall Support
 

Hello
Are there any linux firewalls like smoothwall out there that "easily" support the BT Voyager ADSL modem??
The only other i have been able to find is Ipcop, and i am not sure wether this supports the above hardware.
If you have been able to get it working, i would be grateful for any help :D

Thanks

If you want a Firewall on your Linux box, then you can use iptables.
Iptables is part of the Linux 2.4 kernel.
Take a look at the HowTOs and Tutorials on Netfilter.
I know of two other frontends for iptables: Firestarter and Firewall Builder


Netfilter / iptables

Firestarter
http://firestarter.sourceforge.net/

Shorewall

Firewall Builder
http://www.fwbuilder.org/

IPCop Firewall
http://www.ipcop.org/

What's your distribution? Any recent distrib will include iptables (the linux firewall) support by default, you don't even need to recompile your kernel.
But I suggest you to stay away from Smoothwall/Firestarter or apps like this since they teach you nothing, and always do sloppy work.
Iptables script are not hard to do, just find what port are open on your box (get nmap, it's a nice port scanner, then scan yourself) then block these ports with simple iptables rules like :
iptables -A INPUT -p tcp --dport your_open_port_number -j DROP

easy :P


Btw, Mathieu, you seem to be in the same city as me but we have reallly different opinions about firewall :p Do you have MSN, ICQ or something?

erm
 

hey
thanks for both your replys, but the reason i was looking for something like smoothwall is because i need to share the connection and i hear it is a pain to get it working in linux, with the USB voyager modem!

bah, sharing connection isn't that hard
just read that thread, you might find it interesting, especially the 4th reply :)
