that is correct

yes

will, if you're doing NAT, you can't give the PC a public IP

And

and it will soon lock up

the most common error, causing this problem is if under IP setup, you forget
to input a default router IP
the unit will work as a transparent bridge in this scenario, b/c the default
router is set at the PC end

a rather silly mistake, but still deadly

this.....

actually, Doug and Kevin are busy people, it's the responsibility of your
KarlNet reseller to fully support you

yes

well, here's two examples - open your configurators, and go to (these are
live ISP customers of mine, so if you #$#$% the settings, or modify them in
any way, I will hunt you down and scalp you)

sample NAT config
ip: 65.211.183.55
password: public

sample IP Routing config (/29)
ip: 65.211.183.52
password: public

>What is the correct way??

see above

another reason why your choice of KarlNet vendor is probably one of the most
important decisions that you make (hint: me)

otherwise, I guess you wait until some kind soul takes pity on you
