Subnetting a home network, possible?

[POPone]

i'm trying to setup a subnet on my home network, is this possible with the conventional home small office routers? here's why.

I have my dsl connected to my main Netgear FVS318 router with VPN. So i have this setup with 192.168.1.1 address. Then i have a 3com OfficeConnect access point. I have another accesspoint where it's setup as a bridge, since theres no cat5 running to that room of the house. (The bridge works only with one computer on the other end, I tried setting up it with a switch but it doesn't work reliably.) So my fix now is i threw another Netgear router on the other end of the bridge, then I have two computers connected thru that router. Network traffic works fine, BUT because of NAT, i can't access the two computers behind the secondary router from the main network. (file sharing, printer sharing, etc). Is there a way to bypass the NAT on the secondary router?

Thanks in advance!

To bypass NAT on the secondary router from the main network, you will need to setup a static route in the static routing table on the main router.

You said that the internal address for the main router was 192.168.1.1......Let's assume that the secondary router (behind the bridge) as an EXternal address of 192.168.1.2 and an INternal address of 192.168.2.1 ....

You will need to configure a static route on the main router for the 192.168.2.0 network.

Should be 192.168.2.0 with a hop of (or gateway of) 192.168.1.2

If the main router has a static route table....the above line is the way it needs to be setup. Then, any node behind the main router's NAT will be able to see nodes behind the second router's NAT.

thanks for your response! is there anyway to subnet my main network of 192.168.1.1. So make the secondary external address of 192.168.1.129 then the internal of the secondary as 192.168.1.130 or something. reason being, i have the VPN setup as well, i need at 192.168.100.* addresses for the VPN to route properly. i briefly tried it with no luck, i guess i dont know how to subnet? i thought with a mask of 255.255.255.248 would give me 5 ips. but the router didn't like my settings.

Your network is 192.168.1.0 /255.255.255.0 just to let you know.

You try to subnet 192.168.1.0 using 255.255.255.248

Subnet zero 192.168.1.0-192.168.1.7 <---(Can't use, subnet zero)
subnet one 192.168.1.8-192.168.1.15 (can use *.9 to *.14) = 6h
subnet two 192.168.1.16-*.23
subnet three 192.168.1.24-*.31
subnet four 192.168.1.32-*.39
subnet five 192.168.1.40-*.47
subnet six 192.168.1.48-*.55
subnet seven 192.168.1.56-
...etc
The example on subnet one you can't use *.8 because thats the network address and *.15 is the broadcast address and so on for the others like subnet two you can only use *.17 to *.22 and so on....
Each subnet increment by 8 all the way up to 32 but you can only use 30.

Using 255.255.255.248 will give you up to 30 useable net with only 6 useable host IP. Depending on how much host you want to put into each subnet. That means if you have a total of 6 device or less you would use this but you would have to consider if your network will grow you might try to use another subnet like 255.255.255.240 which supports 14 device per subnet or 255.255.255.224 which supports 30 device per subnet and so on.

I don't quite understand what you mean when you said " i have the VPN setup as well, i need at 192.168.100.* addresses for the VPN to route properly." Can you be more clear about it please..
