Hi all, The following rules do not work anymore and block access to outside: ipfw add pipe 1 ip from 67.xxx.89.78 to any 80 out via xn0 ipfw add pipe 2 ip from any 80 to 67.xxx.89.78 in via xn0 ipfw pipe 1 config bw 1024Kbit/s queue 128 burst 2M ipfw pipe 2 config bw 1024Kbit/s queue 128 burst 2M Using these rules on the server, I can not surf the Internet through the server. In FreeBSD 9.x these rules worked. Doing: links http://www.any_website.com not work My Firewall rules: # ipfw show 00100 67191 13584242 allow ip from any to any via lo0 00200 0 0 deny ip from 127.0.0.0/8 to any 00300 0 0 deny ip from any to 127.0.0.0/8 00400 0 0 check-state 00500 0 0 deny ip from 192.168.0.0/16 to any in via xn0 00600 0 0 deny ip from 10.0.0.0/8 to any in via xn0 00700 0 0 deny ip from 172.16.0.0/12 to any in via xn0 00800 0 0 deny ip from 224.0.0.0/4 to any in via xn0 00900 0 0 deny ip from 255.255.255.255 to any in via xn0 01000 0 0 deny tcp from any to any in tcpflags fin,psh,urg recv xn0 01100 0 0 deny tcp from any to any in tcpflags !syn,!fin,!ack,!psh,!rst,!urg recv xn0 01200 0 0 deny tcp from any to any in tcpflags syn,fin recv xn0 01300 0 0 deny tcp from any to any in tcpflags fin,rst recv xn0 01400 0 0 deny ip from any to any in ipoptions ssrr,lsrr,rr,ts recv xn0 01500 78 2496 deny ip from table(99) to any in via xn0 01600 0 0 deny ip from table(1) to any 01700 276 16560 pipe 1 ip from 67.xxx.89.78 to any dst-port 80 out via xn0 01800 3 144 pipe 2 ip from any 80 to 67.xxx.89.78 in via xn0 01900 4 276 allow icmp from any to any icmptypes 3,11,12 02000 0 0 allow icmp from me to any icmptypes 0,8 keep-state 02100 1 75 deny icmp from any to any 02200 2226 298340 allow tcp from any to me dst-port 4321 in via xn0 setup keep-state 02300 1997 768000 allow tcp from any to me dst-port 995 in via xn0 setup keep-state 02400 1363 519377 allow tcp from any to me dst-port 25 in via xn0 setup keep-state 02500 733 549931 allow tcp from any to me dst-port 587 in via xn0 setup keep-state 02600 8952 8756999 allow tcp from any to me dst-port 80 in via xn0 setup keep-state 02700 2748 2125603 allow tcp from any to me dst-port 443 in via xn0 setup keep-state 02800 0 0 allow tcp from any to me dst-port 143 in via xn0 setup keep-state 02900 0 0 allow tcp from any to me dst-port 110 in via xn0 setup keep-state 03000 1094 360419 allow tcp from any to me dst-port 993 in via xn0 setup keep-state 03100 0 0 allow tcp from any to me dst-port 21 in via xn0 setup keep-state 03200 0 0 allow tcp from any to me dst-port 30000-50000 in via xn0 setup keep-state 03300 3558 1151840 allow tcp from me to any out setup keep-state 03400 6693 880724 allow ip from me to any out keep-state 65534 170 20283 deny log logamount 100 ip from any to any 65535 36 5424 allow ip from any to any When I remove the upload rule, navigation back to work: # ipfw delete 1700 links http://www.any_website.com work again. # uname -a FreeBSD mail.xxxxx.xxx.xx 10.0-STABLE FreeBSD 10.0-STABLE #2 r261419: Thu Feb 6 16:51:10 BRST 2014 root@mail.xxxxx.xxx.xx:/usr/obj/usr/src/sys/GONDIM amd64 It seems that something has changed and that stopped the bandwidth control.
