Network Routing problem.,,

Greetings Friends,

We are plan to migrate N/W on our production.

For the test purpose one of the server make it 2 no's IP Address and 2 different G/W.

For ex:

1.IP:10.x.x.51
netmask:255.255.255.0
G/W :10.x.x.201 its running primary lan card.
-----------------------------------------------
I am planning to configure the second Lan card new IP and netmask , G/W
For ex :
1.IP:10.x.x.236
netmask:255.255.255.224
G/W :10.x.x.221
How can i make 2 G/W in single server.Please advice to me any one.For the testing purpose i want access both IP address from remote location.

Regards
Rajamani

Are these "xx.xx" values the same or
different? Why hide such potentially
important information? Are you afraid that
the Dread Pirate Roberts will attack your
systems if he learns your real (non-routable)
IP addresses?

How do you do that now?

Steven Schweda,

Ok, this is testing only.


lan0 IP :10.37.12.51
subnet :255.255.255.0
G/W :10.37.12.201

lan1 IP :10.39.17.224
subnet :255.255.255.224
G/W :10.37.12.225

Re: Network Routing problem.,,

vi /etc/rc.config.d/netconf and add the below lines to it.

ROUTE_DESTINATION[0]="10.37.12.51"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="10.37.12.201"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""

ROUTE_DESTINATION[1]="10.39.17.224"
ROUTE_MASK[1]=""
ROUTE_GATEWAY[1]="10.37.12.225"
ROUTE_COUNT[1]="1"
ROUTE_ARGS[1]=""

then
/sbin/init.d/net start

Re: Network Routing problem.,,

you should see the routes when you give the command
netstat -rn

ping the gw to check the connectivity

Re: Network Routing problem.,,

check your file
you have given the wrong IP

ROUTE_DESTINATION[0]="110.40.10.51"

it should read 10.40.10.51

How carefully did you look at this stuff?

> INTERFACE_NAME[1]=lan1
> IP_ADDRESS[0]=10.39.17.226
> SUBNET_MASK[0]=255.255.255.224

> DHCP_ENABLE[1]=0
> INTERFACE_MODULES[0]=""

I see "[1]", "[0]", "[0]", "[1]", "[1]",
"[1]", and "[0]".

> ROUTE_DESTINATION[0]="110.40.10.51"
> ROUTE_MASK[0]=""
> ROUTE_GATEWAY[0]="10.40.10.211"
> ROUTE_COUNT[1]="1"
> ROUTE_ARGS[0]=""

I see "[0]", "[0]", "[0]", "[1]", and "[0]".

Do you not understand what array subscripts
are or how they should be used here?

change the

to

ROUTE_COUNT[0]="1"

Re: Network Routing problem.,,

also as steven mentioned

> BROADCAST_ADDRESS[1]=""

change 1 to 0 accordingly.
you need to be carefull and try to understand what you doing.
