Network design / IP Addresing for local network
Hello Experts,
I'm looking at this trying to find ideas for simple ip scheme to be able to forward the public ip and access my end device over the net.
( 95.x.x.x /29 ) ----- ( T-1 ) ------pt to pt -------- (T-1) -------- ( End Device)

Mike, Thank you for quick response ! ! I agree with you on the most used ip's and the internal route forwarded will be an private.
My goal is to not complicate the routing portion of this config, so what would the t1 interaces and gateways be addressed to acheive this ?
adsl public ip : 95.x.x.x /29
router 1 ip :
router 1 gw :
router 2 ip :
router 2 gw:
end device ip :
end device gw:
Thanks again.

So you have 3 segments here
segment 1 Adsl to router 1
segment 2 router 1 to router 2
segment 3 router 2 to end-user devices
I would do something like this:
Segment 1 subnet 192.168.50.0/30 with
adsl internal ip: 192.168.50.1
router1 ip: 192.168.50.2
Segment 2 subnet 192.168.50.4/30
router 1 ip: 192.168.50.5
router 2 ip: 192.168.50.6
Segment 3 subnet 192.168.51.0/24
router 2 ip: 192.168.51.1
end user devices get dhcp 192.168.51.10-254 using gw 192.168.51.1
You will need to add routes to the adsl and router 1 so they know where to send packets bound for 192.168.51.0
segment 1 Adsl to router 1
segment 2 router 1 to router 2
segment 3 router 2 to end-user devices
I would do something like this:
Segment 1 subnet 192.168.50.0/30 with
adsl internal ip: 192.168.50.1
router1 ip: 192.168.50.2
Segment 2 subnet 192.168.50.4/30
router 1 ip: 192.168.50.5
router 2 ip: 192.168.50.6
Segment 3 subnet 192.168.51.0/24
router 2 ip: 192.168.51.1
end user devices get dhcp 192.168.51.10-254 using gw 192.168.51.1
You will need to add routes to the adsl and router 1 so they know where to send packets bound for 192.168.51.0

Very helpful Mike !
Does Telco normally provide the addressing for the point to piont circuit ? Haven't dealt too much with these.
Thanks.

I usually tell people to stay away from the low numbers that most people use by default on consumer routers. (i,e, 192.168.1.0)
Is this for a home network with few hosts:
I would recommend 192.168.50.0/24, 192.168.51.0/24 for a private scheme.
the exact subnet you pick is really based on the number of hosts you need on 1 LAN. Try to stay away from very large subnets to avoid alot of broadcast traffic if you will have many hosts....
