A group of influential people would like to run SLIP from their homes
to machines behind the firewall. I've explained that this reduces network
security to the level of the weakest password, however this does not convince.
What are the worst forms of abuse that can happen via SLIP run "past" (or
around) the firewall? Can I somehow remove from the home machines the
capability of further extending the network in uncontrolled fashion? And
will enforcing modem callback substantially reduce the risk?
Thanks in advance
