1.) The Art
___________
Other Net 192.168.200.240 | |
---------------------------|Linux FW |
eth0 |_________|
eth1|192.168.100.101
|
|
|192.168.100.100
_____|______
| |
| WWW |
|__________|
2.) The Problem:
Need to forward (redirect?) packets received on eth0 of the FW to the WWW
box and obviously send back the requested information. ie. enter
192.168.200.240 in the browser and get a webpage back from WWW. I'm
attempting to use ipchains. At this point I don't even care about a tight
FW, I just need to get the packets flowing. (Will consider other "gratis"
solutions.)
3.) The Scenario on the Linux FW (RH 6.1)
FORWARD_IPV4="true" in /etc/sysconfig/networks
executed insmod /lib/modules/2.2.12-20/ipv4/ip_masq_portfw.o
gateways - Are they required in this situation and if so,
which box(es) should be set up with what for a gateway.
routing table is as follows:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.100.0 * 255.255.255.0 U 0 0 0 eth0
192.168.200.0 * 255.255.255.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
My attempts thus far have been based on IPCHAINS-HOWTO, but it's a bit
difficult to learn unless you have packet flow already.
Any assistance would be appreciate - even literature other than HOWTO.
