IP farwarding in Solaris 9?.... Help!

[Eranga Udesh]

Hi All,

I need to setup a system like this.

I have 2 servers one with IP 192.168.0.1 (Server 1) and the other with
192.168.0.2 (Server 2). I am running some servers in Server 2 (eg. HTTP
server). My service domain name, "testserver.com" points to Server 1. Both
servers run Solaris 9.

Can I install a IP Forwarder or Router in Server 1, so that any TCP packet
(may be for selected ports) comes to Server 1 (192.168.0.1 / testserver.com)
will forward to Server 2 (192.168.0.2) and access the services on Server 2?

Please help me as soon as possible.

Thanks in advance!
Eranga

check out:
[url]http://sourceforge.net/projects/simpleproxy/[/url]

once installed, then just set up whatever ports you want to forward.
IE:

/path/to/simpleproxy -d -L 80 -R new.foo.com:80 -p
/var/run/simpleproxy.pid


Of, if you really just want to ssmush (yes, that's a technical term)
the two servers together, you could just bring down the IP on server 1
and bring it up on server 2. IE:

1. change IP on server 1 (or turn it off)

2. bring server 1's IP up on server 2. IE:

ifconfig eri0 addif 192.168.0.1 netmask ###.###.###.### broadcast
###.###.###.### up

you'll need to change the eri0 to whatever your interface name is (do
an ifconfig -a to check). broadcast and netmask are the same as the
current settings.
