How to: Allow internet access (use integrated NAT, manual IP replacing) |
NetCom has own NAT table. You can share your Internet (WAN) connection with other computers in your network. NetCom NAT works like showed on diagram:
For example you'r network topology and configuration equal to represented on this diagram:
• | Network: 192.168.0.0 |
• | Subnet mask: 255.255.255.0 |
• | Server internal address: 192.168.0.1 |
• | Server external address: 207.46.130.108 |
If you want to allow access to the Intenet for workstations with addresses 192.168.0.12 and 192.168.0.14, do the following:
1. ALLOW ALL
Create rule to allow all network traffic from all to all - (it must be always last item in rules list):
Packet action equal to Allow
2. 192.168.0.12
Create rule with allowed access for 192.168.0.12 from internal to external network:
Packet action equal to Allow
Packets direction equal to Incoming
Protocols equal to Any IP
Source IP equal to 192.168.0.12
Destination IP NOT in range 192.168.0.0 - 192.168.0.255
Replace source IP with you'r external IP (207.46.130.108)
Add data about packet to the NAT table [Enabled]
3. 192.168.0.14
Create rule with allowed access for 192.168.0.14 from internal to external network:
Packet action equal to Allow
Packets direction equal to Incoming
Protocols equal to Any IP
Source IP equal to 192.168.0.14
Destination IP NOT in range 192.168.0.0 - 192.168.0.255
Replace source IP with you'r external IP (207.46.130.108)
Add data about packet to the NAT table [Enabled]
4. CHANGE RULES ORDER
You must change order of rules to this:
1. 192.168.0.12 - allow access to Internet;
2. 192.168.0.14 - allow access to Internet;
3. ALLOW ALL - needed for normal work of Internet connection and local network.
7. ENABLE FILTERING
Select both adapters for filtering (internal and external). |
At this moment filtering started. |
That's all... |
NOTE: |
On client computers address of DNS-server(s) must be defined! |
