Configuration Issue or Routing Issue ?

Model: EAP655-Wall  
Hardware Version: V1
Firmware Version: 1.3.1 Build 20240929 Rel. 44742(4555)

Hello People Much Smarter than Me .

 

I have an EAP655-Wall connected via ethernet cable to an SG2210P switch that switch is connected to my ISP's router. I have created a DHCP scope and vlan on the switch and tagged the vlan to the switch port that the EAP is connected to.

 

On the EAP I have created an SSID with matching vlan and additional added that vlan to one of the ethernet ports on the EAP, however I cannot get internet access from the SSID , although I can get a DHCP lease for any device that is connecting to the SSID or ethernet port.

 

So I am not sure if its just a routing issue or I am missing some additional configuration ?.

 

The details are (not real ip addresses)

 

Base network from ISP router = 192.168.1.0/24

SG2210P switch ip address = 192.168.1.4

EAP ip address = 192.168.1.5

 

dhcp scope on switch  = 192.168.10.0/24

vlan on switch = vlan 10  - interface ip address = 192.168.10.1

 

interface on switch  = untagged vlan 1, tagged = vlan 10

 

SSID on EAP is set to vlan 10

 

From my pc (192.168.1.x address) I can ping the vlan 10 gateway of 192.168.10.1 but not any dhcp addresses in 192.168.10.x

 

 

From a pc on vlan 10 (192.168.10.x address) I can ping anything in the 192.168.1.0x network, I cannot ping or access the internet (ping 8.8.8.8 fails for example)

 

Hopefully someone can help ?

  @GoKiwi 

Which device is the DHCP server for VLAN10? The switch or the ISP router?

We don't recommend having two DHCP servers in one network.

 

Please also share us the DHCP and IP settings on the switch.

I have moved the DHCP scope to a DHCP server in my 92.168.1.0 network - all is working as before  - I can still get a dhcp lease and can still ping across 192.168.10.0 and 192.168.1.0. 192.168.1.0 still has internet access where as 192.168.10.0 does not.

 

The switch is now a DHCP relay and the config from the switch is below

vlan 10
 name "10"

 

ip dhcp l2relay vlan 10
 

service dhcp relay
ip dhcp relay vlan 10 helper-address 192.168.1.25
 

interface vlan 10
  ip address 192.168.10.1 255.255.255.0
  no ipv6 enable
  ip helper-address 192.168.1.25
  ip dhcp relay default-interface
 

interface gigabitEthernet 1/0/4 - This is where the EAP is connected
  switchport general allowed vlan 10 tagged
  gvrp

  lldp med-status
  lldp snmp-trap
  power inline priority high

 

There is a static route on the ISP router - This allows me to ping across the two networks.

4 192.168.10.0/255.255.255.0 192.168.1.4 br0

 

(I dont have direct access to the ISP router)
