You can also enter a remote secure gateway’s domain name in the
Secure
Gateway Address
field if the remote secure gateway has a dynamic WAN IP
address and is using DDNS. The P-792H v2 has to rebuild the VPN tunnel each
time the remote secure gateway’s WAN IP address changes (there may be a delay
until the DDNS servers are updated with the remote gateway’s new WAN IP
address).
Dynamic Secure Gateway Address
If the remote secure gateway has a dynamic WAN IP address and does not use
DDNS, enter 0.0.0.0 as the secure gateway’s address. In this case only the
remote secure gateway can initiate SAs. This may be useful for telecommuters
initiating a VPN tunnel to the company network (see
Section 12.9.12 on page 182
for configuration examples).
The Secure Gateway IP Address may be configured as
0.0.0.0
only when using
IKE
key management and not
Manual
key management.
Finding Out More
See
Section 12.9 on page 173
for advanced technical information on IPSec VPN.
12.1.3
Before You Begin
If a VPN tunnel uses Telnet, FTP, WWW, then you should configure remote
management (

) to allow access for that service.
