Hi all,
Traceroute still won't work. I'm playing around with the rules and
wondering what's right and what's wrong with the traceroute rules. Can
anyone give me some starting points here?
/etc/pf.conf:
ext_if = igc0 # Extern interface
int_if = "{ igc1, igc2 }" # Intern interfaces
localnet = "192.168.2.0/24"
tcp_services = "{ smtp, domain, www, auth, http, https, pop3, pop3s }"
udp_services = "{ domain, ntp }"
email = "{ smtp, imap, imaps, imap3, pop3, pop3s }"
icmp_types = "{ echoreq, unreach }"
icmp6_types = "{ echoreq, unreach }"
nameservers = "{ 195.121.1.34, 195.121.1.66 }"
client_out = "{ ssh, domain, pop3, auth, nportntp, http, https, \
446, cvspserver, 2628, 5999, 8000, 8080 }"
Martians = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, \
10.0.0.0/8, 169.254, 0.0/16, 192.0.2.0/24, \
0.0.0.0/8, 240.0.0.0/4 }"
set skip on lo
# By default, do not permit remote connections to X11
