Hello everybody! I've been having problems working with ppp -auto -nat myisp Everything works fine except that ppp dials unexpectedly. I read the ppp FAQ and I found this problem there. It says that to determ= ine the cause use the following line: set log +tcp/ip I certainly did and I got this cause from the log: Sep 21 09:13:03 BSDincep ppp[3291]: tun0: Phase: PPP Started (auto mode).= Sep 21 09:18:17 BSDincep ppp[3291]: tun0: TCP/IP: DIAL UDP: 10.0.0.1:138 = ---> 10.0.0.255:138 Sep 21 09:18:17 BSDincep ppp[3291]: tun0: Phase: bundle: Establish Sep 21 09:18:17 BSDincep ppp[3291]: tun0: Phase: deflink: closed -> openi= ng Sep 21 09:18:17 BSDincep ppp[3291]: tun0: TCP/IP: OUT UDP: 10.0.0.1:138 -= --> 10.0.0.255:138 Sep 21 09:18:17 BSDincep ppp[3291]: tun0: Phase: deflink: Connected! Sep 21 09:18:17 BSDincep ppp[3291]: tun0: Phase: deflink: opening -> dial= The second line seems to tell me that the dial triggers from an UDP packe= t with ip addresses that are not used in my LAN (192.168.1.255) Who is doing that? And how can I make the dial filter to deny this. I tr= ied the following with no result: # We don't want ICMPs to cause a dialup: set filter dial 0 deny icmp set filter dial 1 permit 0 0 # # or any TCP SYN or RST packets (badly closed TCP channels): # set filter dial 2 deny 0 0 tcp syn finrst set filter dial 3 deny 10.0.0.1 10.0.0.255 Thank you very much for your help.
