Gateway Problems help please

[Transcend]

Under System routing gateway. The gateway op1 gets an gateway i.p.

At first it has the name dynamic. After a reboot an  i.p address is put automatically in there. But it is not the right i.p. Adress. How can i change it to the i.p. address i want it to be?

The i.p. adress of a previous vpn connection appears there. And i have created a new one.

Any help would be great. Because of this my vpn does not work anymore :(

Gateway IP is automatically assigned when "dynamic" word is written.
Go System>Routing
New , choose OPT1 and put your gateway there.

Or go to Interfaces>OPT1 and put your gateway.

if that didn't work
try to put static IP for OPT1 interface not DHCP
