Hi,

Situation:
Users of Network A wants to browse an Intranet Page in Network B.

Where
1. Network A connects to Network B using WAN.
2. Intranet Page is hosted in Network B.
3. Intranet Page is using a local IP.

Question: Can users of Network A access the Intranet Page in Network B?

Thanks in advance.

 

you have to open the firewall or network address translator (NAT) to map a certain IP address that is accessible to Network A to the internal IP address (in Network B) of the web server.

for example, if Network A has IP block 10.0.0.0/8 and Network B has IP block 192.168.0.0/24 for its LANs. if Network A can connect to Network B, it's either Network A has access to the 192.168.0.0/24 block of Network B (via simple routing) or Network B has another set of addresses (e.g. 203.87.128.0/24) that both Network A and the internal Network B can access. if the latter, you'll need to map a certain 203.87.128.0/24 address to the internal web server's IP in Network B's 192.168.0.0/24 block. This is what is called "port mapping." So for example if Network A can access an IP 203.87.128.4 in Network B but cannot access the 192.168.0.0/24 block in Network B, have the router in Network B port-map 203.87.128.4 port 80 (HTTP) or whatever port to the internal web server's IP (e.g. it's 192.168.0.9) port 80 too.

Thanks for the reply cruizer. I'll try and keep you posted on the updates.
