dnat problem

[<support@supsrv.com>]

hello all,
this is my first time posting to this board.  i am having trouble
with my iptables rules.  my configuration consists of a linux
router as the main network gateway and firewall providing NAT and
ipsec.  i have compiled kernel 2.4.17 with freeS/WAN version
1.91.   i have a source nat rule set up so my non-routable
addresses can use the gateway to reach the internet.  i did not use
the MASQUERADE target.

here is my Source nat rule

iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth1 -j SNAT --to
w.x.y.z

I also have some destination nat rules set up.
iptables -t nat -A PREROUTING -d w.x.y.a -p tcp -m tcp --dport 80 -j
DNAT --to-destination 192.168.1.48

There are about 5 additional dnat rules that are basically the same
so I won't list them.

the problem i am having is that the internal private subnet
(192.168.1.0/24) on my network is unable to bring up sites that
have been setup using dnat rules.  external users have no problem
viewing the sites i have set up dnat rules for.

any help would be greatly appreciated.

thanks
