index | next in thread | raw e-mail
I've switched from a DHCP cable modem to a PPPoE DSL modem and thus
started running ppp. I had trouble getting natd to work with ppp, so
I'm now using ppp's nat facilities...
but the rc.firewall rules for denying RFC1918 traffic on the outside
interface seem to block legitimate traffic from my LAN to the Internet
and back also. My solution is to put the following line above the
first "Stop RFC1918 nets ..." line in /etc/rc.firewall:
$fwcmd add pass all from any to any in via ${iif} keep-state
The questions: Will this generate a huge number of dynamic rules for
local traffic, and is there a better way to do this, preferably other
than trying to duplicate my rc.firewall in ppp.conf?
Thanks.
