I set the network config in dhcp, now it's working.
Therefore I don't know why it wasn't in manual...it was a routing issue.
Well now I can't add the repository
The documentation say:
export PKG_PATH="ftp://ftp.NetBSD.org/pub/pkgsrc/packages/NetBSD-<RELEASE-NUMBER>/<PORT>/All"
export PKG_PATH
But I get:
"export command not found"
