DNS Server (for IPSec VPN) If there is a private DNS server that services the VPN, type its IP address here. The NBG-460N assigns this additional DNS server to the NBG-460N's DHCP clients that have IP addresses in this IPSec rule's range of local addresses. Local Policy A DNS server allows clients on the VPN to find other computers and servers on the VPN by their (private) domain names. Local IP addresses must be static and correspond to the remote IPSec router's configured remote IP addresses. Local Address 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. For a single IP address, enter a (static) IP address on the LAN behind your NBG-460N. For a specific range of IP addresses, enter the beginning (static) IP address, in a range of computers on your LAN behind your NBG-460N. Local Address End /Mask To specify IP addresses on a network by their subnet mask, enter a (static) IP address on the LAN behind your NBG-460N. When the local IP address is a single address, type it a second time here. When the local IP address is a range, enter the end (static) IP address, in a range of computers on the LAN behind your NBG-460N. When the local IP address is a subnet address, enter a subnet mask on the LAN behind your NBG-460N. Local Port Start 0 is the default and signifies any port. Type a port number from 0 to 65535. Some of the most common IP ports are: 21, FTP; 53, DNS; 23, Telnet; 80, HTTP; 25, SMTP; 110, POP3. Local Port 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. If Local Port Start is left at 0, Local Port End will also remain at 0. Remote Policy Remote IP addresses must be static and correspond to the remote IPSec router's configured local IP addresses. 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.
