not sure about X programs but there is always iftop or pktstat in
ports/net-mgmt if you just want something realtime (no good for graphing
etc though i'm afraid.) Some of the the plugins for things like
sysutils/gkrellm(2) do things like traffic graphs but you really dont
want them on a firewall. If you dont need absolute realtime then just
enable bsnmp on the internal interface and run something like mrtg or
cacti (or even a very quick and dirty script  using rrdtool via cron)
against it.
