How to move from public IP based network to private IP LAN but using WAP with public IP
Posted on 2007-04-10
There is probably a very simple answer to this question but I can't quite figure it out!
I have a network comprising of 3 pcs and a Mac, no server, on a workgroup, all with manualy assigned public IPs.
We have a block of 8 IPs for our use on a subnet of 255.255.255.248 and a default gateway in the same public IP range for all the offices to share.
The office is in a serviced office block and we access the default gateway using their wireless access point.
We want to install a server and move onto a local private network IP addressing system for our office.
That is, we would like our pcs, Mac and server to be on the 192.168.0.0/24 range behind a hardware firewall.
However, we can only access the internet through the wireless access point with its public ip as the default gateway.
So I am thinking that I will need to install a router which will have a private ip on the internal NIC as the internal default gateway address, but on the external wireless interface connecting to their wap it will have to have the original public ip default gateway on the 255.255.255.248 subnet??
If this is the case what would be the appropriate hardware to use for this setup?
I do hope this makes sense but I am very happy to clarify this if it doesn't.
I am awarding 125 points for the most useful suggestion, however if this question is more difficult to answer than I imagine I am happy to increase the points value.
Look forward to hearing your suggestions.
