Dear
people,
I have two machines Sun Solaris 7 with
ipfilter package in order to filter traffic from Internet. Last week I have
the machines connected to a cablemodem with IP fixed by MAC address and they
run OK.
But today I have to
change of ISP and reconnect using a cablemodem again. In order to get the
Sun machines assigned with an dynamic IP, I configured DHCP client in each
Sun. But they can't get an public IP assigned by DHCP yet, they have been
connected to the cablemodem since 2 hours, and they have the ipfilter
running...but the IP is not assigned !!!
Now I don't know if my
ipfilter rules are blocking the IP assignment in this DHCP client scenario,
so I want you to get your opinion. The rules are:
pass in quick on hme0
proto udp from any to any port = 67 #Only permit DGCP incoming traffic
pass in quick on hme0
proto udp from any to any port = 68 #Only permit DHCP incoming traffic
block in quick on hme0
from 10.0.0.0/8 to any
block in quick on hme0
from 172.16.0.0/12 to any
block in quick on hme0
from 192.168.0.0/16 to any
block in quick on hme0
from 127.0.0.0/24 to any
block in on hme0
all
pass out quick on hme0
proto tcp from any to any flags S keep state pass out quick on hme0 proto
udp from any to any keep state pass out quick on hme0 proto icmp from any to
any keep state
Special thanks !!!!!!!!!
