Dear fellow network architects
Im plannig to connect two physical networks that both have very similar characteristics.
Each network has its own internet gateway (NAT router) and its own dhcp server.
Network A’s router is my trusty openSuse 10.3 box with two network interfaces (one facing the web, the other facing my lan). obiously it has routing between the two interfaces enabled, with masquerading.
Ip range is 10.0.0.0/24
Network B’s router is an ordinary router w/ a bunch of local ports and wireless access point functionality (linksys i think). the linksys router also is the dhcp.
Ip range is 10.0.1.0/24
machines from network A are not allowed to use network B’s internet gateway and vice versa.
what i want is: be able to connect from a machine in network A to a machine in network B (not over the internet) and vice versa.
What physical (wiring) and non-physical (software config.) changes do i need to make?
I was thinking that i’d need to place a router without NAT between the two networks, and maybe tell the internet gateways not to route any traffic directed to the other lan into the depths of the internet.
or would it be sufficient to get a third ethernet interface, add it to network A’s openSuse router and configure a bridge between it’s current local eth. interface and the to be added 3rd eth. interface?
thanks a lot in advance.
