Have a look at man pages of route command.
Use
route delete default 1

but be sure if you are on a different network from you'r server you will loose connection from the server if you'r default route is active

If the interface and default gateway are configured by SAM it will also be in the file /etc/rc.config.d/netconf

If you only use a "route delete" command your default gateway will be set (as set in netconf) after a reboot.

So change the next part of the netconf file:
ROUTE_DESTINATION[n]="default"
ROUTE_MASK[n]=""
ROUTE_GATEWAY[n]="1.1.1.1"
ROUTE_COUNT[n]="1"
ROUTE_ARGS[n]=""

Activate the new netconf using /sbin/init.d/net start

Be aware of the warning in a previous reply, if you are using the gateway via a network session you wil loose the connection!.

hi

i thing the best solution is to modify the file /etc/rc.config.d/netconf

change the following lines
ROUTE_DESTINATION[n]="default"
ROUTE_MASK[n]=""
ROUTE_GATEWAY[n]="1.1.1.1"
ROUTE_COUNT[n]="1"
ROUTE_ARGS[n]=""

by this way your modification is permanent

Hi David,

It should be noted that if a non-default subnet mask was applied at route creation, it must again be stipulated in the route delete. The default mask is 255.255.255.0
Run
netstat -rvn
To see if a non-default mask is in play.

Rgds,
Jeff
