RAS, NAT, Port Forwarding

[onur]

hi, maybe someone can help me...

 

i want server 2008 to act as a router, so im running Windows Server 2008 with RAS, NAT.

 

i have also a SBS 2003 running.

all required ports are forwarded to the SBS.

(when everythig is running fine i want to run the SBS in HyperV Envirement)

 

the problem is, that port forwarding is only functional for external computers.

 

 

when i type:

www.sentek.org then this only works from outside computers.

(also it doesent works at home if i type the Internet IP Adress).

 

route print - gives this

Hi

the problem is, that port forwarding is only functional for external computers.

Do you mean, that SBS is not visible from computers in 192.168.0.0 network?

 

Maybe you set port forwarding to forward ports only from external interface (194.183.136.234), not internal?

[onur]

the server is visible from local network, no problem.,

 

and its true, i only set port forwarding for external interface, becouse the internal interface gives no option to forward...

 

with an harware router this configuration is making no problem.

 

if this is not possibel with microsoft, i will run an linux router in hyperV envireoment.

So what is your problem? Describe it more, please.

example:

internet IP: 168.x.x.x

NAT Server IP: 192.168.0.1

port 1234 should be routed to 192.168.0.50:1234

 

forwarding is working when i try this from outside (meaning - if you try this, it will work).

 

from the local network: forwarding is not working for (168.x.x.x:1234)

it doesent matter if i try it wiht domain:1234, or 168.x.x.x:1234

allways the same,

Look here, I have a problem I think like yours.

A website binded to *:80 on server doesn't opens from local network on address http://somedomain.net (which is binded to an Internet IP) and opens only on internal address (http://10.0.0.1)

I mean, it seems that Windows 2008 doesn't answers on packages from Internal network targeted to External IP.

I my example, it's from 10.0.0.x -> 81.x.x.x (10.0.0.1) and doesn't works

In your, from 192.168.x.x -> 168.x.x.x (192.168.0.50) and doesn't works too!

Maybe, additional network routes are required, unfortunately I don't know yet
