Dear all,
I am looking for the NAT solution on Linux( RedHat 6.2). What I hope to do is
static NAT as following:
Office network gateway machine database servers network
129.158.166.0/23---| |------ 10.100.1.0/24 --server 1
| |
eth0 eth1
129.158.166.1 10.100.1.2
eth0:0
129.158.166.2
server 1 - one of database server in "database servers network", ip is
10.100.1.10.
gateway machine - linux 6.2(kernel 2.4-test11 with Netfilter & NAT support)
I hope users could talk to database server from office network. So I did the
alias on eth0 and want to the NAT from 129.158.166.2 to 10.100.1.10. What I did
is using iptables as following:
#iptables -P INPUT ACCEPT
#iptables -P OUTPUT ACCEPT
#iptables -P FORWARD ACCEPT
#iptables -t nat -A PREROUTING -i eth0 -p tcp -d 129.158.166.2 --dport 23 -j
DNAT --to 10.100.1.10:23 <=test the telnet
After that I telnet 129.158.166.2 from office, the telnet session just hang. I
use the "tcpdump" to check the eth0, eth1. Both have packages flow.
I do not know what wrong with my iptables configuration and is there any other
better NAT solution on linux?
Appreciate any suggestions!
