- The ones I've seen have only been different in the way that one and 1

- I've done it. Multiple times, in different configurations, using

- To answer the question you asked: they are on different physical
- media. To answer the question you were trying to ask: the two
- interfaces on the gateway host have different IP addresses.
-
- As a bonus, I'll point out that multiple SLIP interfaces on a single
- host can share a single IP address, and are distinguished by the IP
- address of the destination. I'll confess to not having tried this
- particular configuration on a NetBSD box, but it works on other
- BSD-based IP stacks.

- You may or may not have been right. I pointed out that the answer to
- this question was apparently YES (after all, at worst it's a SMOP, and
- another poster reference his writeup on this subject), but that this
- was no longer a "simple" question, and the operation was probably more
- complicated than changing ISPs to one that didn't object to your
- registering your own network. Of course, if you're coat-tailing on a
- school or employer, that would involve actually spending money.

-
- And I wish that people who do not have sufficient understanding of a
- problem to know if an answer was correct would not pretend that they
- do.
