Bond or Bridge or something else

Hello,

I searched on the web and didn't find a solution to my specific need. So I am asking for advice on this forum !

I have 2 seperated networks.

Network A with an ADSL router and access to Inteet used for teachers
Network B with a Cable router and access to Inteet used for students

Now I have a Ubuntu machine hosting a webserver. I would like this webserver to be accessible to both networks A & B.

So I installed two network cards in the Ubuntu machine and coected each one on a Network. eth0 on network A and eth1 on network B.

What must I do to configure this Ububtu machine so that the webserver can be accessed indiferently from both networks.

Must I Bond the interfaces? Must I Bridge the interfaces? Must I use another solution?

Can someone give me some advice on how to make this work?

Thank you.

Andrew
