Ok -
My ISP is moving me off of SL/IP and onto PPP. So, I've got to brave
the waters and set everything up again.
I believe using pppd is pretty straight forward, and shouldn't present
me with too many problems... but, I have a question.
Right now, I use the following ipfw/natd rules to do some forwarding
and gateway stuff:
(from /etc/rc.conf):
natd_interface="sl0"
natd_flags="-m -u -dynamic -redirect_port tcp 10.0.0.11:telnet 6666 -redirect_port udp 10.0.0.11:telnet 6666"
And, from /etc/rc.firewall:
...
$fwcmd add divert natd all from any to any via ${natd_interface}
...
$fwcmd add 400 pass tcp from any to 166.82.177.48 7490
$fwcmd add 401 pass tcp from any to 10.0.0.10 7490
$fwcmd add 65000 pass all from any to any
So - now - how do I redo this using pppd? Basically, I'm asking what
the natd_interface should be. Is it tun0? Just what is the interface
in this case? I'd rather change a little as possible, so I'd like to
just get pppd working (kernel-mode ppp) with my current natd/ipfw
setup instead of using the ppp natd support...
- Thanks -
