Greeting all,
I have a bit of a complicated question.
I have two ethernet devices, eth1 and eth2.
eth1 is where my internet comes from. It is in the form of 202.172.122.208/29.
It has another IP range, 202.172.122.72/29. What I want to be able to do is
route 202.172.122.72/29 to eth2, so that other machines can use those IPs,
any ideas on how to do this, I cannot work out how to do this.
You haven't made it too clear what exactly you are trying to do, from what i
gather this should work on your linux box
*cannot agree more*. Topology and better expression of scenario
requiring this helps always. This may be a convoluted solution to a
simple problem. I must add we are operating in relative vaccum here.
ip route add 202.172.122.72/29 dev eth2
Does your isp route 202.172.122.72/29 to you ?
eth2 has a DHCP server, which only gives out IPs 202.172.122.74 to
202.172.122.76.
seems to be outside subnet cited. *.72/29 is .72-.75* Only 2 addresses
can be served on DHCP from a subnet of 4.
eth1 is basically just hooked into my internet router, while eth2 is hooked
into a switch, and will be used for other computers.
If anyone could help me with this setup, I would more then appreciate it.
Thank you very much,
- Tim Groeneveld
You seem to want to use public IP addresses against mapping public to
private addresses. If so, why not just connect the router to the switch
and connect all computers to the switch? Will also be better to get a
combined /28 subnet. No private addresses? No need for firewall?
I would use the Linux machine to map the public addresses to private
addresses for specific services to a DMZ.
