no Internet with host-only network(not NAT-wanna limit traffic via IPTABLES

I m using VMware-server-1.0.0-27828.i386 on a Suse 10.0 box.

Guest VM is win98.   I m using host-only networking (not NAT, coz I wanna limit traffic via IPTABLES). 

The 98VM gets default gateway (=vmnet1) via vmnet1-DHCP Server and can ping itself + vmnet1.

My Problem:

the 98VM does not have Internet access - even when disabling default SuSE Firewall.

Using script of 'dmair' ... (\[url]http://www.vmware.com/community/thread.jspa?messageID=340442[/url])

#! /bin/bash

IPT=/usr/sbin/iptables

_VMNET=192.168.230.0/24

_WIN98=192.168.230.128

IF_VMNET1=192.168.230.1

IF_PUB1=dsl0

IP_PUB1=0.0.0.0

$IPT -P INPUT ACCEPT

$IPT -P OUTPUT ACCEPT

$IPT -P FORWARD ACCEPT

$IPT -F -t nat

$IPT -F -t mangle

$IPT -F -t filter

$IPT -X

echo 1 > /proc/sys/net/ipv4/ip_forward

$IPT -t nat -A POSTROUTING -s $_WIN98 -o $IF_PUB1 -j SNAT --to $IP_PUB1

\#     $IPT -t nat -A POSTROUTING -s $_WIN98 -d IP.OF.INTERNET.HOST --dport port -o dsl0 -j SNAT --to-source IP.OF.HOST.ETH[/code]

... still no Internet.

Does anyone have advice for me ?
