I also had this problem in 3.1-RELEASE. In fact, the problem is one of the reasons I upgraded this evening to 3.2. I am connected to my ISP (pacifier.com) via a dialup connection with a dynamically allocated IP address. Another strange thing is that I can telnet to pacifier and ftp *back* to my home machine just fine. Before you ask, my firewall configuration is "open": # ipfw show 00100 1516 174622 allow ip from any to any via lo0 00200 0 0 deny ip from any to 127.0.0.0/8 65000 6717 529654 allow ip from any to any 65535 0 0 deny ip from any to any I am doing *some* filtering in ppp.conf, but nothing on ports 20 and 21. I am denying inbound and outbound tcp and udp packets on ports 194 and 5190 through 5193 in the in and out filters. When I attempt an ftp, it eventually times out and says: ftp: connect: No route to host Here is part of the output of tcpdump -e -vv -i tun0: 22:08:41.452569 ip: ip34.van28.pacifier.com.1092 > pacifier.com.ftp: S 307640048:307640048(0) win 16384 (DF) (ttl 64, id 4398) 22:08:41.549604 ip: vancts12.pacifier.com > ip34.van28.pacifier.com: icmp: host pacifier.com unreachable (ttl 255, id 5268) I'm really stumped with this one, and I'd appreciate any help anyone would care to offer.
