Hello Everyone,
I have a FreeBSD 6.1-RELEASE box that has two network cards (Dual
Homed?). Each card is on a different network, as following
(from /etc/rc.conf):
ifconfig_fxp0="inet 192.168.20.36 netmask 255.255.255.0"
ifconfig_rl0="inet 192.168.210.6 netmask 255.255.255.0"
defaultrouter="192.168.210.1"
route_servers="-net 192.168.2.0 192.168.20.1"
static_routes="net1 net2"
route_net1="-net 172.20.68.0 192.168.20.1 255.255.254.0"
route_net2="-net 192.168.2.0 192.168.20.1"
The fxp0 is connected to the outside world while the rl0 is connected to
the internal networks. I noticed whenever I ssh or try to telnet to port
25 on this box from 192.168.2.x for example, it delays the response by
something like 10 seconds, I even have a tcpdump of that!
Can someone explain what is wrong with my setup? Should I have routed
running? (I personally don't feel it is needed)
Thanks in advance for your help and guidance.
P.S. I got the above setup based on my understanding of the handbook, so
forgive me if I didn't understand it correctly :)
I believe the actual fault is that you don't understand how networks
are done, based on the /etc/rc.conf entries you've listed above.
I suggest that you pick up Computer Networks: A System Approach by
Peterson and Davie to pick up a basic idea of how networking and routing
works, and maybe consult <http://en.wikipedia.org/wiki/Classful_network>
as a basis for planning out how things will be done, in particular with
network addresses.
Providing netstat -nr" output would be beneficial as well when
troubleshooting issues with routing, as well as any firewall rules you
have in place.
