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 !!!!!!!!!
