Dual WAN issues on ER605 V2
Background
Model | Version |
ER605 V2 | 2.1.2 |
TL-SG2428P | 1.1.7 |
8 x EAP620 HD V2 (US) | 1.0.3 |
2 x EAP620HD V3 (US) | 1.0.2 |
2 x EAP245 V3 | 5.0.6 |
OC200 V1 | 5.7.6 |
I have 2 VLANs, VLAN ID 1 = Omada devices. VLAN ID 10 = customers.
WAN 1 is connected by PPPoE with a GPON converter. Likewise with WAN 2.
I do not have VPN profile on the system
No port forwarding
A few Switch ACLs to block intervlan traffics to Omada and Router interface from the customers VLAN.
All the devices above are adopted by Omada OC200 5.7.6. I have Dual WAN connected to ER605 V2. Load balance: 1 to 1. 250 up / 250 down on each WAN.
The issue is ER605 becomes unresponsive after the device is booted up with 2 WAN active after 5 minutes into operation. All the APs cannot connect to the internet. Neither can devices connected to LAN (VLAN ID 1)
I have tested this ER605 firmware 2.0.1, 2.1.1, 2.1.2.
- All will not work unless I unplugged the secondary WAN from the ER605.
- The system will require a reboot for it to be functional again.
I thought it was DHCP issues on the router but I can confirm all newly joined devices joined the system received an IP address and connected to Omada system with 0 issue other than no Internet.
What can I do other than disable one of the WAN? Is there an update to mitigate this issue?
