I'm using user PPP. When I use the following rule set, I can ping out and in, and telnet out but NOT telnet into my box via tun0. When I use tcpdump to watch tun0, I don't see any packets for telnet coming in. Does anybody have any ideas? set filter in 0 permit icmp set filter out 0 permit icmp set filter in 1 permit udp src eq 53 set filter out 1 permit udp dst eq 53 set filter in 2 permit tcp src eq 23 estab set filter out 2 permit tcp dst eq 23 set filter in 3 permit tcp src eq 80 set filter out 3 permit tcp dst eq 80 set filter in 4 permit tcp dst eq 113 set filter out 4 permit tcp src eq 113 Thanks Mark -- ========================================================================= UNIX IS user friendly, it's just very choosy about who it calls a friend! ========================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
