hi

does anyone have an idea how to solve my problem?

I have a redhat 8 box for routing between 3 segments:
eth0 Internet - 202.x.y.162/30
isp side 202.x.y.161/30
linux router side 202.x.y.162/30
eth1 DMZ - currently I turned it off.
eth2 Intranet - 192.168.1.0/24
linux router side 192.168.1.1/24 (as default gateway)
all Intranet workstations use win2000 OS.

I use ip masquerade/nat for ip forwarding.
#iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
#iptables --append FORWARD --in-interface eth2 -j ACCEPT

I also set my linux router as cache-only DNS (forward to ISP DNS).

when I tried to browse internet from linux router, everything is fine.

but when i tried to browse internet from win2000 client,
--> I can ping linux router or ip on internet
--> I can nslookup from win2000 cmd using linux router's dns.
but
--> I CANT browse any internet addr using IE.

any suggestions r welcome.

many thanks,
anton

am i to assume you have 3 nic's but are using 2?

eth2 Intranet - 192.168.1.0/24
linux router side 192.168.1.1/24 (as default gateway)

is your eth2 = 192.168.1.1 ?

what are your clients ip setup?
