Model: T2600G-28TS(TL-SG3424)
Hardware Version: V3
Firmware Version: 180201

Hi, I'm a new user here,

I have a managed switch T2600G-28TS, and i must create 4 VLAN and, if possbile, i woudk like to use one (1) DCHP server and configure a DHCP server relay for each VLAN.

I follow this example:

https://www.tp-link.com/us/support/faq/2221/

but when I try to set the routed port, I have an error: The IP address conflicts with an existing one.

I have created 4 VLAN : 10, 20, 30 , 40.

Then i have assigned a specific port: VLAN-10: port  10 to 12, VLAN-20: port  13 to 16, VLAN-30: port  17 to 20, VLAN-40: port  21 to 24.

For each VLAN I have defined interface, for exmpale: VLAN-10  Inteface IP 192.168.10.1

 

Then I configured static rout for each VLAN (exmpale vlan 10)

 

Next step:

L3 FEATURES > DHCP Service > DHCP Server > DHCP Server: ENABLE

L3 FEATURES > DHCP Service > DHCP Server > Pool Setting : for VLAN-10....

then: L3 FEATURES > DHCP Service > DHCP Relay > DHCP Interface Relay 

and set for each VALN the IP of the DHCP SERVER, in my case ip is 192.168.0.111 and this is IP of my MODEM ADSL.

In the configuration of modem ADSL I haven't changed anything.

 

 

WHen I connect a PC on a port of VLAN 10, the system relase correctly IP and gateway (IP: 192.168.10.2, gateway: 192.168.10.1, DNS:8.8.8.8) but is not possible to navigate in internet, no ping out the subnet....

Where I wrong?

thank you.

It would so much easier to understand, if you put text cfg instead of pics.

Well, DHCP Relay is needed, when your DHCP-server exists in the same VLAN as a client, but in different subnet. 

When your DHCP-Server is in another VLAN, you must configure DHCP VLAN Relay.

 

Let us understand, why you want to have several VLANs. Maybe, it will be enough for you to configure only port isolation? I do not understand for now, why you need VLANs.

 

Otherwise, if you really want to have VLAN10, then you need to configure vlan interface, as you did for VLAN10, configure VLAN interface for VLAN1, which goes your ADSL Modem, configure static routes for modem and back.

thank you.,

I need to isolation the offices because the people that use the offices are members of different companies. I have 5 office, and I need to create a specific LAN for each office where the modem for internet is shared.

If possible I prefer to create 5 LAN with different class of Ip. (192.168.10.X ..... 192.168.20.X, .... 192.168.50.X)

The PC, printer, NAS must be isolated from office to office.

For example:

PC, NAS and printer of office A must be uses shared modem but cannot view the pc and other peripherical of other offices

What's your router? I think it's easier to configure it there.

Zyxel USG60 firewall with 2 wan port and 3 lan port

 

USG60 is also DHCP server for my network

As I know, usg60 supports everything you need. You can configure trunk port from your switch to your router. Configure several IP-interfaces on router, configure several DHCP-Servers there.
