I am extending our company network and invite comment
as to the 'most useful' / 'least hassle' addressing schema
+------------+
| routing |ng0
LAN a --+ host +---------------- internet
| A |
| +-------+
| |ng1 |
+------------+ |
-/-
WAN link
-/-
+------------+ |
| routing |ng0 |
LAN b --+ host +-------+
| B |
| |
+------------+
FWIW the internet link and the WAN link are via a frame relay
setup with netgraph, and nat -u is running on host A(ng0).
LAN a has a legal range 203...
Host A(ng0) has a legal ip 139...
LAN b is a RFC1918 net 192.168.1.0
I can setup the WAN link on a different RFC1918 net 192.168.2.0
and route accordingly
on A
ifconfig ng1 192.168.2.1 -netmask 255.255.255.0
route add -net 192.168.1.0 192.168.2.2
on B
ifconfig ng0 192.168.2.2 -netmask 255.255.255.0
route add default 192.168.2.1
_or_
I can just setup the routing tables with the interface names only
on A
route add -net 192.168.1.0 -interface ng1
on B
route add default -interface ng0
The Exam Questions ;-)
[1] If you were doing this WAN net, which method would you choose?
[2] Explain your choice?
TIA
