Hi all,

The problem can actually be resolved by using NAT. However, Solaris does
not bundle in any NAT feature like Linux does.

Thanks to Koos van den Hout for giving me reply. i'm looking into any
3rd party sw capable of doing NAT on Solaris. Alternatively, i'm also
looking into SunScreen (Sun firewall sw) in order to make use of the NAT
feature for this purpose.

 Thanks a lot.

You'll need to setup NAT (network address translation) on the Solaris
that does the dialout to translate between the 192.168.1.x internal
addresses and the 'real' addresses on the Internet out there. Standard
Solaris does not support this at all. Your best bet, if you want to
keep using that Solaris box as 'router' is to find and install ipfw (ip
firewall) which can be a statefull firewall and do network address
translation.

I'd say this is not for the faint of heart, especially since ipfw needs a
64 bit compiler.

You might consider using an old (recycled) PC with Linux as dialout/
mail machine. Dialout/nat (masquerading in Linux lingo) is much better
supported in Linux. But I say "consider" since this is a different learning
curve from Solaris and you may not be very interested in Yet Another Unix
to learn.

Good luck!
