Setting cooperation with dynamic DNS server
On the
Dynamic DNS
tab, select a DDNS provider, enter DNS name for which dynamic record
will be kept updated and set user name and password for access to updates of the dynamic
record. If DDNS supports wildcards, they can be used in the host name.
Once this information is defined, it is recommended to test update of dynamic DNS record by
clicking on
Update now
. This verifies that automatic update works well (the server is available,
set data is correct, etc.) and also updates the corresponding DNS record (IP address of the
firewall could have changed since the registration or the last manual update).
If an error occurs while attempting to update DNS record, an error is reported on the
Dynamic
DNS
tab providing closer specification of the error (e.g. DDNS server is not available, user
authentication failed, etc.). This report is also recorded in the
error
log.
8.4 Proxy server
Even though the NAT technology used in
WinRoute
enables direct access to the Internet from
all local hosts, it contains a standard HTTP proxy server. Under certain conditions the direct
access cannot be used or it is inconvenient . The following list describes the most common
situations:
1.
To connect from the
WinRoute
host it is necessary to use the proxy server of your ISP.
Proxy server included in
WinRoute
can forward all queries to so called
parent proxy server
).
2.
Internet connection is performed via a dial-up and access to certain Web pages is blocked
(refer to chapter
). If a direct connection is used, the line will be dialed before the
HTTP query could be detected (line is dialed upon a DNS query or upon a client’s request
demanding connection to a Web server). If a user connects to a forbidden Web page,
WinRoute
dials the line and blocks access to the page — the line is dialed but the page is
not opened.
