this is my redhat9 linux server the ip 59.144.124.58 (eth1) is our internet service provide ip,192.168.1.2 (eth0) is the ip of our backoffice lan network,192.168.100.149(eth2) is the ip of or trading network and 10.32.138.42 is i added in the server for 2 reasons

1.) my internet works on my local lan from the 192.168.1.2 ip,i want it also work from 10.32.138.42 ip,it means internal routing between internal ips.

2.) we have the bombay stock exchange router in our office which having the ip 10.32.138.1,when you give the router's ip address in client windows xp pc as a gateway then only the software works.Now i want to run the software from 10.32.138.42(eth3)ip,so i have to put 10.32.138.1 as a gateway in eth3 ifcfg-eth3 file.

this means the eth3(10.32.138.42)ip will do 2 work for me it gives me the internet packets and bse trading packets also

The bse trading software using following ports when i open from 10.32.138.1 (router's ip)here iam giving the netstat for the ports.

Active Connections

Proto Local Address Foreign Address State
TCP 10.32.138.55:1627 137.201.13.201:21 ESTABLISHED
TCP 10.32.138.55:1629 137.201.13.201:21 ESTABLISHED
TCP 127.0.0.1:1033 10.32.138.55:1627 ESTABLISHED

here the ip 137.201.13.201 is the ip of bse trading server and port 21

so please give any route and iptables command in detail


Thanks

You can install last fwbuilder version and do it graphically, forgetting iptables and route commands. fwbuilder uses iptables and route, so you can take the file made by fwbuilder and then, if you want, touch it manually, or see how does it do something.
