LAN OK, WAN OK, Won't pass data from LAN to WAN
Phone Case #: C6613856

CONFIG:
Static IP, No DHCP, Manualy entered Gateway Router IP & DNS server IP's.

LAN Connection Works:
Config/Status via browser works.  Answers pings to it's LAN & WAN
interface IP Addresses.

WAN Connection Works:
Diag reports successful connection to ISP gateway router & Pri DNS
server.  Verified by telnet to 520B and using ping to test connectivity
to ISP router & dns.

PROBLEM:
520B will not pass traffic between LAN and WAN. (cannot ping ISP from
computer on LAN)

The 520B is acting like its internal firewall is blocking all through
traffic.

Have tried various combinations of NAT enabler/disable, Firewall
enable/disable, etc.
Turned on error logging but nothing in the syslog messages has helped so
far.
