The first test I tried was a ping to a valid internet host "ping 209.xxx.xxx.xxx", no response from the ping, tried the ping several times with no response but I would ctrl-c the ping command after 10-15 seconds thinking my network setup was incorrect. Checked my internet connection by pinging the same internet host from the FreeBSD gateway and the windows box, both pinged fine. Re-checked my setup, after several minuets of examining config files etc... everything looked fine. I then used ftp from the PB, and got a quick connection with no problems, tried the ping from the PB again, worked fine, installed Lynx from ports, http connects fines. Rebooted the PB and logged in via SSH, pings to the intranet and internet work fine. Just thought I would share this with the list, and if the problem shows itself again I will post again.
