Synology Router RT2600ac User Manual

							 21 Chapter 8: Manage Local Network Connection
The chapter introduces various features to efficiently manage the local network.
Set up an IPv6 Router
By default, your Synology Router works as an IPv4 router assigning IPv4 \
addresses to client devices. It can also 
become a mixed IPv4/IPv6 router to assign IPv6 addresses.
To set up your Synology Router as an IPv6 router, go to Network Center > Local Network > IPv6.
Note: Only IPv6-supported devices can receive IPv6 addresses assigned by your\
 Synology Router.
Set up DHCP Services
As a DHCP (Dynamic Host Configuration Protocol) server, your Synology Router can assign dynamic IP 
addresses to DHCP clients (i.e. network devices) within your local network.
To find a list of DHCP clients and their network configurations (e.g. MAC and IP addresses), go to Network 
Center > Local Network > DHCP Clients.
To reserve the assigned IP addresses for the clients, go to Network Center > Local Network > DHCP 
Reservation.
Note: Your Synology Router can assign both IPv4 and IPv6 IP addresses. To assign IPv6 IP addresses to DHCP clients, please enable the IPv6 function at Network Center > Internet > Connection > Primary Interface > IPv6 setup first.
Set up Static Routes
A static route is a routing path manually configured to pass data to and from a specific destination service/device. 
The static route does not automatically change with the network configuration, and its routing information is not 
exchanged between other routers. 
Setting up static routes can benefit you in the following scenarios:
• When the network (e.g. a home local network) is small and may not grow\
 fast into a complex network
• When you do not wish to share routing information (e.g. IP addresses and network configuration) with other 
routers for security reasons
To set up static routes, go to Network Center > Local Network > Static Route.
Note:
1. We advise you not to use static routes when the network is large and comp\
lex, because maintaining static routes in this environment can be time-consuming.
2. You can set up IPv6 static routes after enabling the IPv6 function on you\
r Synology Router.
Set up IPTV & VoIP
The IPTV & VoIP services allow you to connect an STB (set-top box) or VoIP phone to your Synology Router for 
multimedia services from the ISP or for phone communication. Before using the services, you need to have\
 the 
VLAN ID provided by the ISP for the setup.
To set up the IPTV & VoIP services, go to Network Center > Local Network > IPTV & VoIP.

Router or eject the storage at Control Panel > Storage > Storage.
Define User/Folder Privileges
After external storage is established on your Synology Router, you can create shared folders for public use (e.g. 
“public”) and home folders for individual users.
To create shared folders, go to Control Panel > Storage > Shared Folder. There you can also set users’ access 
privileges to the folder.
To create users, go to Control Panel > User > User. There you can also set the user’s access privilege to shared 
folders.
Install & Manage Network Printers
Your Synology Router can become a printer server, allowing you to connect a non-networked printer to be shared 
with other devices. You can also set up Google Cloud Print to print out needed documents from\
 everywhere.
To install a network printer, please attach it to the USB slot.
To manage a network printer connected to your Synology Router, go to Control Panel > Device > Printer.
Note: Please refer to the compatibility list for supported network printers.
Install & Manage 3G/4G Dongles
With a 3G/4G dongle, your Synology Router can still provide Internet acc\
ess to client devices via a cellular 
network. 
To install a 3G/4G dongle to your Synology Router, please attach it to the USB slot.
To manage the dongle settings, go to Network Center > Internet > 3G & 4G.

from the target. 
• Normal connection: The response packet comes from the target instantly. 
• Slow connection: The response packet comes from the target with significant delay or with high variance in 
response times. 
Delayed or unresponsive targets may be due to the following:
• The target is busy dealing with huge traffic to and from other hosts/clients
• The target website/IP address is down/not working.
• The Internet/local network connection of your Synology Router is not properly configured.
• The ISP service is down.
If the problem is external to your Synology Router, you should consult your ISP or other relevant service providers 
for assistance.
To diagnose connection problems with Ping, please go to Network Tools > Ping.
Traceroute
Traceroute is a utility used to examine the Internet pathway taken to reach a specific destination. The physical 
route will be displayed on a Google Map, along with the time lapse spent\
 between two adjacent route points. 
With Traceroute, you can better understand how your traffic is being routed. 
To diagnose connection problems with Traceroute, please go to Network Tools > Traceroute.

s.
Does the router have SPI firewall?
Yes. SPI firewall is always enabled. No related management options are provided.  
						

							 30 Chapter 13: FAQ
Can the VPN Server package work on my router if I use IPv6 connection?
If the router provides IPv6 connection, you can only use VPN Server as a\
n OpenVPN server. The other types of 
VPN (PPTP and L2TP/IPSec) are not supported.
What can I do if I can't connect to the router via VPN connection?
Make sure you enable the VPN pass-through function and select the corres\
ponding options of the VPN protocols 
(PPTP, L2TP, IPSec) that you use.
Why does a message pop up notifying me I do not have a valid certificate when 
I visit certain HTTPS websites?
When you visit an HTTPS website, the website will continuously send a request to SRM for a valid certificate. If 
the website or some of its elements is in the block list, SRM cannot respond to the request with a valid certificate.
To work around this issue (due to the HSTS concerns), you can add the w\
ebsite to the allow list (at Network 
Center > Parental Control > Web-filter > Edit Allow List).
