Problem:

I completly wiped every device and even the whole site. So this is on an absolute fresh setup and default settings out of the box.

When Creating a fresh VLAN (type: interface in the UI) clients on this vlan get the correct ip, default gw and dns. but cant reach anything .. not even the default gw.

My Setup

• OC200 v1 - Firmware 5.13.30.20
• ER605 v2.0 - Firmware 2.2.3
• TL-SG2428P v4.0 - Firmware v4.0.8
• EAP615-Wall(EU) v1.0 - Firmware 1.0.12
• 2x EAP653(EU) v1.0 - Firmware 1.0.12

I have two VLANs as follows:

(CLI output just for the forum. I'm configuring only via SDN web ui )

#show interface vlan 1
     vlan1 ports:2 3 4 5

I have configured a switch port only with VLAN10:

----snip----
TL-SG2428P#show running-config interface gigabitEthernet 1/0/16
!TL-SG2428P
interface gigabitEthernet 1/0/16
  switchport general allowed vlan 10 untagged
  switchport pvid 10
  no switchport general allowed vlan 1

  lldp med-status

• When I now connect a wired client to port 1/0/16, it successfully obtains the IP address 10.0.0.10.
  • Sometimes the client fails to receive an ip at all. seems kinda random
• However, the client CANNOT (!) reach its advertised default GW 10.0.0.1 via ICMP ping. No network connection is possible at all.
• A client from VLAN1, on the other hand, can reach the IP 10.0.0.1 via ICMP ping.

Screenshots  :

These are the routes which are created automatically. is route number 5 correct? Thought that the nexthop should be 10.0.0.1/24 instead.

Am i missing something?
