thanks for the reply, I've seen that the ftp_passive is enabled on squid by default, so it's no needed to enable. Later thinking about this again, Im going to try without squid as ftp proxy because it should be dificult to select only ftp trafic from the squid machine because is mixed on the same port with http trafic. So to solve the problem, I will send ftp conections through only one adsl, what makes ftp work without problems for a user inside the LAN conecting to an ftp server in passive mode. I will put this rules on pf.conf of the openbsd firewall. pass in on $int_if route-to ($ext_if1 $ext_gw1)} proto tcp from $lan_net to \ !vpn_net port 21 keep state #ports on ftp openbsd servers #acording to openbsd documentation pass in on $int_if route-to ($ext_if1 $ext_gw1)} proto tcp from $lan_net to \ !$vpn_net port >49151 keep state #ports in ftp passive servers #acording to wikipedia pass in on $int_if route-to ($ext_if1 $ext_gw1)} proto tcp from $lan_net to \ !$vpn_net port >1023 keep state I haven't try it yet, tomorrow let's see if it works. Any comment would be much appreciated.
