Q4: I cannot access Internet and send/receive emails; what should I
do?
A4:
This problem mainly happens to users who use the PPPoE or
Dynamic IP Internet connection type. You need to change the MTU size
(1492 by default). In this case, go to “WAN Settings” to change the MTU
value from default 1480 to 1450 or 1400, etc.
Q5: How do I share resources on my computer with users on
Internet through the device?
A5:
To let Internet users access internal servers on your LAN such as
e-mail server, Web, FTP, via the device, use the "Virtual Server" feature.
To do so, follow steps below:
Step 1: Create your internal server, make sure the LAN users can
access these servers and you need to know related service ports, for
example, port number for Web server is 80; FTP is 21; SMTP is 25 and
POP3 is 110.
Step 2: Enter Port Forwarding (also called Port Range Forwarding on
some products) screen from device web UI.
Step 3: Complete the Start Port (also called External/Ext Port on
some products) and End Port (also known as Internal/Int Port on some
products) fields, say, 80-80.
Step 5: Input the internal server’s IP address. For example, assuming
that your Web server’s IP address is 192.168. 0.10, then simply input it.
Step 6: Select a proper protocol type: TCP, UDP, or Both depending
on which protocol(s) your internal host is using.
Step 7: Click Enable and save your settings.
