SubjectRE: Linux NAT questions- (kernel upgrade??)
Hi.. I follow your instruction, but I encounter this issue, my kernel need
to be upgrade? MAy I know how to determine the current kernel version and
how to upgrade it??

[root@guava /root]# iptables -t nat -A PREROUTING -p tcp --dst -i
eth1 -j D
NAT --to-destination
iptables v1.1.1: can't initialize iptables table `nat': iptables who? (do
you need to insm
Perhaps iptables or your kernel needs to be upgraded.

[root@guava simc]# rpm -ivh iptables-1_2_0-6_i386.rpm
error: failed dependencies:
kernel >= 2.4.0 is needed by iptables-1.2.0-6

This isn't really a kernel question. I think you'd better ask it on some
linux network list/newsgroup. But here's an answer anyway....

You could add to eth0:
ip addr add dev eth0
and then use NAT to redirect these to the webserver:
iptables -t nat -A PREROUTING -p tcp --dst -i eth1 -j
DNAT --to-destination

This should work, AFAIK, but i didn't try it myself. You could also try to
use the arp command (see 'man arp'), but i don't know exactly how that

Good luck!
