P-660 series Support Notes

10. What is DDNS wildcard? Does the P-660 support DDNS wildcard?

Some DDNS servers support the wildcard feature which allows the hostname,
*.yourhost.dyndns.org, to be aliased to the same IP address as yourhost.dyndns.org.
This feature is useful when there are multiple servers inside and you want users to be
able to use things such as www.yourhost.dyndns.org and still reach your hostname.
Yes, the P-660 supports DDNS wildcard that http://www.dyndns.org/ supports. When
using wildcard, you simply enter yourhost.dyndns.org in the Host field in Menu 1.1
Configure Dynamic DNS.

11. Can the P-660's SUA handle IPSec packets sent by the IPSec gateway?

Yes, the P-660's SUA can handle IPSec ESP Tunneling mode. We know when
packets go through SUA, SUA will change the source IP address and source port for
the host. To pass IPSec packets, SUA must understand the ESP packet with protocol
number 50, replace the source IP address of the IPSec gateway to the router's WAN
IP address. However, SUA should not change the source port of the UDP packets
which are used for key managements. Because the remote gateway checks this source
port during connections, the port thus is not allowed to be changed.

12. How do I setup my P-660 for routing IPSec packets over SUA?

For outgoing IPSec tunnels, no extra setting is required.
For forwarding the inbound IPSec ESP tunnel, A 'Default' server set in menu 15.2.1 is
required. It is because SUA makes your LAN appear as a single machine to the
outside world. LAN users are invisible to outside users. So, to make an internal server
for outside access, we must specify the service port and the LAN IP of this server in
Menu 15. Thus SUA is able to forward the incoming packets to the requested service
behind SUA and the outside users access the server using the P-660's WAN IP
address. So, we have to configure the internal IPsec as a default server (unspecified
service port) in menu 15.2.1 when it acts a server gateway.

13. What is Traffic Shaping?

Traffic Shaping is a feature in the P-660. It allocates the bandwidth to WAN
dynamically and aims at boosting the efficiency of the bandwidth. If there are serveral
VCs in the P-660 but only one VC activated at one time, the P-660 allocates all the
Bandwidth to the VC and the VC gets full bandwidth. If another VCs are avtivated
later, the bandwidth is yield to other VCs after ward.
