I'm a newbie at setting up a linux firewall router and I'm running into some issues. I have a couple of books that I got just to help me out in the Linux world; however they don't seem to cover the topic's adequately.If anybody can help me out I'd appreciate it.
I have installed RH 7.2 using the custom setting and selected Router/Firewall role. I also disabled IPCHAINS and made sure that IPTABLES is running in all of the init levels. One of the major problems I'm running into is that my outbound NIC eth1 is using dhcp from the internet provider and I don't have static settings and cannot determine my default gateway on this card. I'm not sure how to configure my /etc/sysconfig/network-scripts/ifcfg-eth1 file Do I have to use the route command to set up routes or do I use IPTABLES to accomplish this? Basically what I want to accomplish is to use NAT internally (I set up a 192.168.2.0 network internally)and IP masquarading. I'm not currently using a DNS server internally (I plan to use one as a forwarder), so I have to use the ISP's. I plan to set up a web server and would allow incoming port 80 traffic to be directed to this server. I also would like to allow all traffic going from my internal LAN to go out. Any suggestions would be greatly appreciated. I've been looking forward to setting up rules and getting familiar with this but I'm not at that point yet. Thanks!
