OK! I have a Class C in my ethernet!

No! It's dynamic created by PM.

OK!

OK! My network is 200.251.217.0, it's in ether0.
200.251.217.1 ( My Internet Gateway )

I think this is normal. Let's rip example:
1) In my pc rip say: "who has 200.251.217.67"? ( via ether0 )
my PM say: 200.251.217.237 have! And the route is dynamicly
created.
1) In PM rip say: "who has 200.251.217.67"? ( via ether0 )
my PM say: 200.251.217.237 have! And the route is dynamicly
created too.

I see that it's working because all broadcast an route questions are
solving via ethernet.

BUT! I'm not know if it's the best way to do this configuration.

OK! It isn't in the same subnets. Attention:
PM router: 200.251.217.237 - Last subnet of my class C.
Subnets that I routing: 200.251.217.64/28 and 200.251.217.96/27

I'm assing then addesses from 200.251.217.129 plus 30. All this IPs are
free and are unsing in ports S0-218.

> Do you have an address pool? Is it big enough?

No, I don't do this command but, I think that isn't the default,
I'll verify this.

> Do you have the ports set as assigned? Do you have an assigned address?

All IPs are dynamicly used from 200.251.217.219.
