If both Ethernet ports are enabled, it is necessary to specif y which port is used in certain special
circumstances. Make the appropriate selections described below. C lick Apply changes.
Field
Field description Usage tips
IPv4 gateway
preference The IPv4 address to which the ISDN
Gateway will send packets in the absence
of more specific routing (see IP routes
configuration).
Therefore, it only makes sense to have
precisely one default gateway, even though
different default gateways may have been
configured for Ports A and B. Use this
option to decide which port's default
gateway configuration to use as the ISDN
Gateway's default gateway.
If Ethernet Port B is disabled, you
cannot specify that port as the
default gateway preference.
Selecting Port B as default gateway
preference then disabling Port B will
cause the preference to revert to
Port A.
IPv6 gateway
preference
The IPv6 address to which the ISDN
Gateway will send packets in the absence
of more specific routing (see IP routes
configuration).
As in the IPv4 case, it only makes sense to
have precisely one default gateway, even
though different default gateways may have
been configured for Ports A and B. Use this
option to decide which port's default
gateway configuration to use as the ISDN
Gateway's default gateway.
If Ethernet Port B is disabled, you
cannot specify that port as the
default gateway preference.
Selecting Port B as default gateway
preference then disabling Port B will
cause the preference to revert to
Port A.
