Description Evilham 2020-01-03 18:27:42 UTC
I just lost some time over this and didn't think of checking rc defaults or rc.conf, except when someone mentioned it on IRC.

There was a related bug for the handbook:

Having that patch in the handbook would have also saved me the surprise, as man ppp basically suggests that the NAT functionality is disabled by default, but starting ppp with rc.conf contradicts that.

I would think mentioning this behaviour with a hint to man rc.conf would be enough, this can be done under:


But would also be useful on the second paragraph of the description, where the -nat flag is introduced.

I am willing to propose a patch for this and to re-open 44443 and propose a patch for it too if this approach were acceptable.

FTR, this is what I was working on when I discovered this issue and would re-use bits of it as real-life examples of using ppp(oe) on FreeBSD.

(as of this bug report these are quite advanced drafts but require more editing)
