My FreeBSD Box is following:
_____________
| | ethernet card
| FreeBSD4.5|<================>Internet
| | (static IP)
+-----------+
Now my client needs dial-up to the box to get access
to internet.
_____________
Modem | | ethernet card
client =======>| FreeBSD4.5|<==============>Internet
dial-up | (gateway) |
+-----------+
For the FreeBSD server, it doesn't need a dial-up
configuration, and I have only one modem.
Could you tell me how to setup this gateway. Or any
ideas?
In this situation, should I add the following lines to
the rc.conf?
ppp_enable="YES"
ppp_mode="ddial"
ppp_profile="dialisp"
ppp_nat="YES"
Or before ppp running, add natd_enable="YES" to
running NAT instead of ppp_nat?
The last line of /var/ppp.log says:Jul 12 14:54:18
mail ppp[166]: tun0: Warning: 10.0.0.2: Cannot
determine ethernet address for proxy ARP
It seems "enable proxy" has some problem.
Best wishes!
