I am at a lose to understand where in the Lucent Manual it says you should
enter a static route for the local ether0 subnet. I see lots of people doing
this, and they should not.
YOU SHOULD NEVER ENTER A STATIC ROUTE FOR THE LOCAL ETHER0 SUBNET.
YOU SHOULD ONLY ENTER A STATIC ROUTE FOR NEXT HOB ROUTES TO A REMOTE SUBNET.
Sorry for the shouting, but this really annoys me.
Once you enter it, it is a pain to get rid off.
Idiots guide to changing the ether0 IP address on any Lucent Portmaster
product:-
Example:-
If your ether0 address is currently 10.10.10.1 with netmask 255.255.255.0
and you wish to change it to 192.168.180.1 with netmask 255.255.255.0
Plug into console port. (You don't have to, but it is easier sometimes)
>set ether0 addr 192.168.180.1
>set ether0 netmask 255.255.255.0 (you have to enter this, even if it does
not change,this is the line which adjusts the routing table)
>save all (Good Idea but no need for a reboot)
The routing table will be changed to match the new IP address.
The entry for the local subnet should always have flag "NL".
NEVER do the following:-
add route 192.168.180.0/24 192.168.180.1 1
Now, the easiest way to get rid of the "NEVER DO" static route is as
follows.
>save all
>erase file routes
>reboot
I hope this helps some people.
