Help :) Configure IP addresses...

[Bojan123]

Ok... i'm newbie in this.

Router IP: 192.168.150.1
LAN addresses range: 192.160.150.x
Subnet mask: 255.255.255.0
Router gets IP from provider in range: 85.94.142.x

Now i want to configure each computer on network with different public IP address.

What do i need to set? Here is pics by default...


Help...

Hi Bojan123

if your provider assigns you a complete network, just configure this network as DMZ:

Code: Alles auswählen

DMZ IP Address:  85.94.142.1
DMZ Netmask:     255.255.255.0

and change the masquerading option for the default route to "masking intranet only". you can change this at ip-router -> routing -> touting-table by selecting the route with addresss 255.255.255.255 and netmask 0.0.0.0

because the DHCP server only assigns IP addresses from the intranet, you have to configure each host in the DMZ manually:

Code: Alles auswählen

Host IP address:  one address from your network (85.94.142.2 .. 85.94.142.254)
Host netmask:     255.255.255.0
Default gateway:  85.94.142.1 (the LANCOM)
DNS server:       85.94.142.1 (the LANCOM)
WINS server:      85.94.142.1 (the LANCOM)

I set this:

Code: Alles auswählen

if your provider assigns you a complete network, just configure this network as DMZ: 

Code:  ‹ Select ›  
DMZ IP Address:  85.94.142.1 
DMZ Netmask:     255.255.255.0  


and change the masquerading option for the default route to "masking intranet only". you can change this at ip-router -> routing -> touting-table by selecting the route with addresss 255.255.255.255 and netmask 0.0.0.0

I am sorry... but where i need to set this? Guide me...

Code: Alles auswählen

Host IP address:  one address from your network (85.94.142.2 .. 85.94.142.254) 
Host netmask:     255.255.255.0 
Default gateway:  85.94.142.1 (the LANCOM) 
DNS server:       85.94.142.1 (the LANCOM) 
WINS server:      85.94.142.1 (the LANCOM)

Hi Boran123

am sorry... but where i need to set this? Guide me...

this depends on the operating system that is running on the hosts (Windows/Linux/MAC-OS etc...).

Hi Bojan123

my problem is, that i don't have an english XP, but i can try..

start -> settings -> network (?) opens an explorer window that shows all your network adapters. do a right click on the LAN adapter and select "properties". In the properties dialog select "inetrent protocol (TCP/IP)" and press the "properties" button. In the next dialog you can enter IP address, netmask, gateway and DNS server.

To configure the WINS server (if needed) press "advanced" and select the WINS tab. On this tab press the "ADD" button configure the WINS server.

At last press OK on each dialog - that's all

Not working...

Code: Alles auswählen

Host IP address:  one address from your network (85.94.142.2 .. 85.94.142.254) 
Host netmask:     255.255.255.0 
Default gateway:  85.94.142.1 (the LANCOM) 
DNS server:       85.94.142.1 (the LANCOM) 
WINS server:      85.94.142.1 (the LANCOM)

is this correct? ...if i set Host IP address as 85.94.142.x ... then how will my computer act in LAN? what is his IP address? I don't get this part...

Hi Bojan123

i thought that you wanted a "normal" network structure - that means:

normal Workstations are placed in the intranet (behind the NAT) and
some Servers are placed in the DMZ (directly accessible from the internet)

for these servers you need static ip addresses (else they wer not accessible from the internet) from the public address range. i told you how to configure these servers.

To access the servers from your intranet you just address them by their public addresses.

as i see now, you want do do something else - you want some or all of your hosts in your intranet beeing accessible from the intranet.

This can be done by a N:N-NAT that maps the hosts from your intranet to the DMZ. The N:N-NAT ist confgured at IP router -> N:N-Mapping -> N:N-NAT table. Enter an new entry:

Code: Alles auswählen

Destination remote site: name of your internet connection, e.g. INTERNET
Original source address: 192.168.150.0
Netmask:                 255.255.255.0
Mapped source address:   85.94.142.0

this entry mapps your whole intranet to the DMZ. In this case you have to give all your hosts static addresses out of your intranet to be able to access them from the intranet.

AFAIK you should not do this beacause it is a high security risc - especially because you say, that you are a newbie

I don't need whole intranet, just 2 computers.
For example: one computer with IP Address: 192.168.150.18 and another 192.160.150.28

What's the settings for DMZ and for N:N-NAT now?
i'm sorry i bothering you

Hi Bojan123

you can leave the DMZ settings as they are, because the settings depend on what your provider assigns to you - all of my examples started on the assumption that your provider assigns a network with a netmask of 255.255.255.0. If you don't have a 255.255.255.0 network, than you have to change some addresses, depending on your real netmask.

For the N:N-NAT you just make two entries, one for each host, eg:

Code: Alles auswählen

Destination remote site: name of your internet connection, e.g. INTERNET
Original source address: 192.168.150.18
Netmask:                 255.255.255.255
Mapped source address:   85.94.142.18


Destination remote site: name of your internet connection, e.g. INTERNET
Original source address: 192.168.150.28
Netmask:                 255.255.255.255
Mapped source address:   85.94.142.28

Nothing my public IP address is still same.
Router is connected at: 85.94.142.125 and my client IP addess is still same.

[Bojan123]

Send it to my private messages.

Thank you.
