Subject: [FW1] static ip routing problem
Help !!!!
QUESTION:
who can help me with the following problem :
we
have build a wan with 3com linkbuilder II isdn router
andsuperstack II
hubs.
we have for example the following ip range in
use:
192.168.100.1 default gateway and superstack ii isdn
router
192.168.101.1 superstack II isdn
router
192.168.102.2
"
"
192.168.103.3
"
"
192.168.104.1
"
"
192.168.100.11 unix machine
192.168.100.15 cobalt cube with
isdn router to
ISP
This machine is also running DNS service for
the workstation on range 192.168.100.1
the other range's where
workstations are on have static ip
numbers. On router 192.168.100.1 we use
static route tables where all the subnets 101.1 102.2 are mentioned in the
tables. From all the subnets we can go to the unix machine on 192.168.100.11.
On range 192.168.100.??? through DNS al ip numbers for the workstations are
correctly distributed.
But now we have the following problem
:
When we add the following static route :
0.0.0.0 0.0.0.0
gateway 192.168.100.15
to router 192.168.100.1 , to force all the
internet trafic
to go to the cobalt cube (our ISP connection) , the default
gateway becomes chanced in the route tables from 192.168.100.1 to
192.168.100.15 , which causes the problem that the workstations which have to
access the unix machine can not find the unix box anymore. When we change the
default gateway back to 192.168.100.1 everything works fine. The
big problem is that it can happen every minute on the day. When we delete the
route 0.0.0.0 0.0.0.0 then we dont have the problem. But then the internet
connection wont work. I think it has something to do with RIP but I'm not
sure. Can anyone give me a helpfull hint or tip how to solve this
problem.
Thanks in advance
