Yes, the 126.96.36.199 is supposed to be the IP address of your FTP server
and "bge0" would be the network interface that is on the "other side
of the firewall" to the FTP server (the inteface into which FTP SYN
packets are first seen by the firewall when people want to connect
to the ftp srver.)
You should only need the one rule and no, it does not need to involve
the ftp-data port. That is managed by the in-kernel proxy.
