Hi, I'm having problems connecting to my freebsd box from my network, I've tried nearly everything without any success. I think its a problem with my firewall rules. I cannot ping/telnet/ftp into my freebsd machine. I can however connect to the outside world from the bsd box. How can I remove the default "deny" clause for the firewall in my kernel options? Here is my firewall table (ipfw): 00100 52 3640 allow ip from any to any via lo0 00200 0 0 deny ip from any to 127.0.0.0/8 65000 156 10249 allow ip from any to any 65535 0 0 deny ip from any to any I ran tcpdump on the freebsd machine, I think the kernel is receiving the connection requests, but is not passing it through the firewall. Outside network = p3.scully Freebsd mc = p1.scully 13:44:35.504743 p3.scully > p1.scully: icmp: echo request (DF) .. .. 13:45:03.509338 p3.scully > p1.scully: icmp: echo request (DF) 13:45:04.509438 arp who-has p1.scully tell p3.scully 13:45:04.509523 p3.scully > p1.scully: icmp: echo request (DF) 13:45:04.509645 arp reply p1.scully is-at a5:a5:a5:a5:a5:a5 13:45:05.509668 p3.scully > p1.scully: icmp: echo request (DF) .. .. 13:45:31.513951 p3.scully > p1.scully: icmp: echo request (DF) .. 13:45:33.569860 p3.scully.1040 > p1.scully.telnet: S 4274696198:4274696198(0) win 5840 <mss 1460,sackOK,timestamp 234528 0,nop,wscale 0> (DF) 13:45:34.514374 arp who-has p1.scully tell p3.scully 13:45:34.514498 arp reply p1.scully is-at a5:a5:a5:a5:a5:a5 13:45:36.564739 p3.scully.1040 > p1.scully.telnet: S 4274696198:4274696198(0) win 5840 <mss 1460,sackOK,timestamp 234828 0,nop,wscale 0> (DF) I've been breaking my head over this for a while now.. any help would really be appreciated.
