I got a full load of 6.1p4 installed and all built. I have pppoe and ipfilter running almost perfect. Clients can use the machine (as a router) and get out perfectly! No issues with network performance at all. I am very pleased...until... I found out that the router itself cant get out 100%. My ipconfig is basically this: bge0 - 10.43.82.174 alias 10.43.82.171 - for bind9 views alias 10.43.82.51 - for bind9 views bge1 - connected to dsl modem well I cant even telnet from the machine to itself! 'destination unreachable' DNS requests from the server itself (to itself - it runs bind) are unanswered yet it is able to fully answer requests from internal or external clients...just not itself! If I use a public DNS server -or- use the IP of the machine I want to connect up to, the router is able to get out and uses the correct IP. I used the same configs from solaris on here (ipf.conf and ipnat.conf) and only needed to change sppp0 to tun0. this should take care of anything the machine itself needs: ============ipf.conf====================== # Pass LAN traffic to/from bge0 pass in quick on bge0 all keep state keep frags pass out quick on bge0 all keep state keep frags # Pass traffic to WAN and keep state pass out quick on tun0 proto tcp all flags S keep state keep frags pass out quick on tun0 proto udp all keep state keep frags pass out quick on tun0 proto icmp all keep state keep frags ========================================== I am totally baffled. Its like I am being blocked somehow but even with ipfilter WIDE open - traffic still wont pass. I am wondering if this is some quirk with the interface aliases...although running the basic same setup on solaris - it works perfectly. -JD
