MultiCom Firewall User’s Manual 99
Your cabling is incorrect
Service Provider
Verify that your Internet Service Provider uses DHCP to configure your
connection to them. Other possible connections may be PPPoE or a static IP
configuration.
State: Trying to get address or State: failed or State: Assigned or State:
Expired
Your cabling is incorrect
Be sure that the WAN interface light on your MultiCom Firewall is green.
If it is not you either have the wrong cable, a faulty cable or the broadband
modem is not plugged in. Try switching cables and verify that the modem is
indeed turned on.
Your modem is not configured as a bridge
Your broadband modem must be configured as a bridge for you to connect
directly to your Internet Service Provider. Verify with the instruction
manual of your modem that it is indeed configured as a bridge. If the two
above steps are not showing a problem this may be your problem.
You changed the time on your firewall but did
not reboot.
The default date of your MultiCom Firewall is January 1970. DHCP works
on a lease system where IP configurations are good for a specified amount
of time. When the original lease runs out your MultiCom Firewall will
attempt to renew its IP configuration information but will erroneously report
that the IP configuration has expired (since the current date is now more
then 30 years in the future.) The easiest fix for this is to reboot the
MultiCom Firewall and it will make a fresh request using the new time.
Your WAN and LAN interfaces are using the
same IP address range
This will normally only happen office to office connections since the default
IP range of 10.0.x.x for your LAN network is never used on the Internet.
Check that the WAN network is not assigning address in the 10.0.x.x range
