FIELD
Local Local IP addresses must be static and correspond to the remote IPSec router's
configured remote IP addresses.
Two active SAs can have the same configured local or remote IP address, but
not both. You can configure multiple SAs between the same local and remote
IP addresses, as long as only one is active at any time.
In order to have more than one active rule with the Secure Gateway Address
field set to 0.0.0.0, the ranges of the local IP addresses cannot overlap between
rules.
If you configure an active rule with 0.0.0.0 in the Secure Gateway Address
field and the LAN's full IP address range as the local IP address, then you
cannot configure any other active rules with the Secure Gateway Address field
set to 0.0.0.0.
Addr Type Press [SPACE BAR] to choose SINGLE, RANGE, or SUBNET and press
[ENTER]. Select SINGLE with a single IP address. Select RANGE for a specific
range of IP addresses. Select SUBNET to specify IP addresses on a network
by their subnet mask.
IP Addr Start When the Addr Type field is configured to Single, enter a static IP address on
the LAN behind your ZyWALL.
When the Addr Type field is configured to Range, enter the beginning (static)
IP address, in a range of computers on your LAN behind your ZyWALL.
When the Addr Type is configured to SUBNET, this is a (static) IP address on
the LAN behind your ZyWALL.
End When the Addr Type field is configured to Single, this field is N/A.
When the Addr Type field is configured to Range, enter the end (static) IP
address, in a range of computers on the LAN behind your ZyWALL.
When the Addr Type field is configured to SUBNET, this is a subnet mask on
the LAN behind your ZyWALL.
Port Start 0 is the default and signifies any port. Type a port number from 0 to 65535. You
cannot create a VPN tunnel if you try to connect using a port number that does
not match this port number or range of port numbers.
Some of the most common IP ports are: 21, FTP; 53, DNS; 23, Telnet; 80,
HTTP; 25, SMTP; 110, POP3
End Enter a port number in this field to define a port range. This port number must
be greater than that specified in the previous field. This field is N/A when 0 is
configured in the Port Start field.
Remote Remote IP addresses must be static and correspond to the remote IPSec
router's configured local IP addresses. The remote fields are N/A when the
Secure Gateway Address field is configured to 0.0.0.0.
Two active SAs cannot have the local and remote IP address(es) both the
same. Two active SAs can have the same local or remote IP address, but not
both. You can configure multiple SAs between the same local and remote IP
addresses, as long as only one is active at any time.
Addr Type Press [SPACE BAR] to choose SINGLE, RANGE, or SUBNET and press
[ENTER]. Select SINGLE with a single IP address. Use RANGE for a specific
range of IP addresses. Use SUBNET to specify IP addresses on a network by
their subnet mask.
