14.2.2 Policies 309
port 443 (HTTPS) to web proxy
This checkbox enables transparent HTTPS access to SX-GATE's web proxy.
Connections to any destination's port 443 will be redirected to the local port 8084.
This option is not available if transparent proxying, content
filtering or SSL interception has been disabled or user
authentication has been enabled in the web proxy configuration.
port 21 (FTP) to FTP proxy
Analogical to the previous option, this switch will redirect connections to port 21 to SX-
GATE's FTP proxy (port 2121).
port 5060 (voice over IP SIP) to SIP proxy
This switch affects packets corresponding to the Voice over IP protocol SIP. Regardless
of the destination IP, packets to TCP and UDP port 5060 will be delivered to the IP of
SX-GATE and so to the SIP proxy.
port 110 (POP3) to POP3/SMTP proxy
This option redirects connections to an Internet IP on TCP port 110 via SX-GATE's
POP3 proxy (port 8110).
port 25 (SMTP) to
Enable this option to intercept direct SMTP connections to the Internet and redirect
them to a service on SX-GATE. From the technical point of view, the destination IP of
connections to port 25 will be replaced by SX-GATE's IP.
mail relay server
Select this option to redirect the connection to SX-GATE's mail relay server. All
further processing is done by SX-GATE, just as if the sender didn't try a direct
Internet connection but delivered straight to SX-GATE.
SMTP proxy
This will forward the mail to SX-GATE's POP3/SMTP proxy (port 8110), which
in turn connects to the originally addressed mail server. If enabled, SX-GATE's
SMTP proxy will perform a virusscan on the outgoing mail. However the actual
processing of the message is done by the mail server as predetermined by the
sender.
port 53 (DNS) to DNS forwarder
Use this checkbox to pass DNS packets to SX-GATE's caching name server. Both,
TCP and UDP packets to port 53 will be affected.
