dial-on-demand, packet filtering, idle timeouts, etc). The IPX support is pretty much there but more work needs to be done in sys-bsd.c for the interface ioctls (Linux has a very different way of configuring IPX interfaces). Along the way some things have temporarily been lost due to very messy conflicts. I will recover them shortly when I can think clearer. The main one is the local:remote address override in pap-secrets and chap-secrets. Some other home-grown features (dns1,dns2) have been implemented differently. Microsoft's chap client auth hacks have been implemented. There are bound to be more rough edges... The changes for connect-max-retries doesn't fit well with the dial-on-demand code.
