LABEL DESCRIPTION
Content When you select IP in the Local ID Type field, type the IP address of your computer
in the local Content field. The ZyWALL automatically uses the IP address in the My
IP Address field (refer to the My IP Address field description) if you configure the
local Content field to 0.0.0.0 or leave it blank.
It is recommended that you type an IP address other than 0.0.0.0 in the local
Content field or use the DNS or E-mail ID type in the following situations.
When there is a NAT router between the two IPSec routers.
When you want the remote IPSec router to be able to distinguish between
VPN connection requests that come in from IPSec routers with dynamic
WAN IP addresses.
When you select DNS or E-mail in the Local ID Type field, type a domain name or
e-mail address by which to identify this ZyWALL in the local Content field. Use up to
31 ASCII characters including spaces, although trailing spaces are truncated. The
domain name or e-mail address is for identification purposes only and can be any
string.
My IP Address Enter the WAN IP address of your ZyWALL. The ZyWALL uses its current WAN IP

0.0.0.0.
The VPN tunnel has to be rebuilt if this IP address changes.
