In configurations where you are using the DHCP services
of the 3100 ICP controller and Network Address
Translation (NAT) on the WAN port, you should not need
to modify the 3100 ICP DHCP settings. The default IP
addressing on the 3100 ICP system is suitable for 90% of
all installations.
Ensure that your DSL service provider does not
block the use of other outgoing e-mail services
(Simple Mail Transfer Protocol). Some DSL service
providers block other outgoing e-mail services to
prevent network users from using their service for
e-mail spamming.
