howto start with gateway / router / masquerading
Hi there,
I have only basic knowledge in Unix but I'm eager to learn.
I have a new complex (for me) exercice and I have no idea how to start.
I have a regular network on witch I'm trying to plug another network.
Here is an image of the physical network.
All three networks work fine and all machines within the same network can communicate.
What I need is to set cassiopeia (a GNU/Linux Debian) to enable communication between networks:
Let me give more specific needs:
So far, I have set machines like this:
Now comes my question:
What should I install on cassiopeia (GNU/Linux Debian) to serve my needs? Is is a gateway, a router or what? Do you know free softwares? Do you know man pages to help me configure it?
Thanks for your help.
Santiago
I have only basic knowledge in Unix but I'm eager to learn.
I have a new complex (for me) exercice and I have no idea how to start.
I have a regular network on witch I'm trying to plug another network.
Here is an image of the physical network.
- On the left is the original, three-node, standard, home network (192.168.1.0 / 255.255.255.0): An internet box (192.168.1.1), my computer (192.168.1.32) and a server (cassiopeia 192.168.1.224).
- I've added two ethernet adapters to cassiopeia.
- One belongs to the top right network (172.16.199.0 / 255.255.255.0): a four-node network with cassiopeia (172.16.199.1) and 3 machines (172.16.199.151..153)
- The second belongs to the bottom right network (172.16.70.0 / 255.255.255.0): a two-node network that could host more machines but I'm laking a switch.
What I need is to set cassiopeia (a GNU/Linux Debian) to enable communication between networks:
- Set cassiopeia as gateway to the internet for 172.16.199.xxx
- Set cassiopeia as gateway to the internet for 172.16.70.1
- Set cassiopeia as a link between the two 172.16 networks
- When 172.16.70.151 requests something like 172.16.199.152, it stays in the top right network
- When 172.16.70.151 requests something like 172.16.70.1, it's routed to the bottom right network
- When 172.16.70.151 requests something like Google, it's routed to the internet box
- When 172.16.70.1 requests something like 172.16.199.151, it's routed to the top right network
- When 172.16.70.1 requests something like Google, it's routed to the internet box
- address = 172.16.199.151..153
netmask = 255.255.255.0
gateway = 172.16.199.1 - address = 172.16.70.1
netmask = 255.255.255.0
gateway = 172.16.70.254
What should I install on cassiopeia (GNU/Linux Debian) to serve my needs? Is is a gateway, a router or what? Do you know free softwares? Do you know man pages to help me configure it?
Thanks for your help.
