Model: OC200  
Hardware Version: V2
Firmware Version: 2.15.2 Build 20240410 Rel.31260

Hello everyone, I have a problem with my policy routing. I have 3 ISPs (WAN, WAN/LAN1, WAN/LAN2).


I created a VLAN (123), created a wireless network with this VLAN and routed it through WAN/LAN1.

At the moment, my WAN/LAN1 is offline, it should be, and I expect that there should be no Internet on my wireless network (VLAN123), because it is redirected through the WAN/LAN1 port, but the Internet works through WAN, or through WAN/LAN2, if WAN does not work.

Use the other WAN port, this checkbox is not selected.

The same problem with VLAN124 and the WAN/LAN2 port.

 

Load balancing has this setting

Hi  @Hank21 

today I did some more tests, and noticed that when WAN/LAN1 is offline, but has an IP address other than 0.0.0.0, then all the policy routing rules work as expected.

Hi @denis-odessit 

Have you also configured the Link Backup on Load Balancing? Try to disable the link backup and try again.

Hi @denis-odessit 

I just made the test with the configuration you provided and it works fine. That is, my VLAN 123 will lose Internet connection when the WAN/LAN1 offline, when the other VLAN is still having Internet connection via WAN and WAN/LAN2.

 

May I know the model and the firmware of your gateway? Please try to upgrade to the latest firmware and try again.

Hi @denis-odessit 

Could you share the IP address you got when you connected to the test SSID? Was it 192.168.101.x? Please help to share how you made the test. And if you tracert 8.8.8.8, will it be different when the WAN/LAN1 is online or offline?

  @Hank21 ,

if WAN/LAN 1 is online everything works as expected, when I connect to the test wifi I get the address 192.168.101.11, if you do a trace route when wan/lan1 is offline, the traffic goes through WAN, I see the WAN gateway ip on the second hop, if WAN and WAN/LAN1 are not working (offline), on the second hop I see the WAN/LAN2 gateway ip, but if all 3 ISPs are online, on the second hop I see the WAN/LAN1 gateway ip as expected.

 

My WAN/LAN1 is a Starlink, and on shore it doesn't work, it only starts working a few miles from shore, and when I'm on shore the Starlink doesn't receive CGNAT, and the WAN/LAN1 gateway has ip 0.0.0.0, there may be a problem in this?

Hi  @Hank21 ,

Looks like the problem is in Starlink, I'm currently at sea and my WAN (5G modem) is offline, I route traffic through the WAN and the internet is not working as expected. But in the same situation, when I’m on the shore and everything is the other way around, WAN is online and WAN/LAN1 is offline, it doesn’t work that way. But how to solve this now?

 

Sorry for my English, it's not my native language

The Starlink situation is weird.  In my SL days, 192.168.100.100 was the address of the dish itself, this really shouldn't be what's assigned to the WAN port of the Omada router.  

 

I assume you're using V2 (square dish) and bypassing the supplied router from Starlink?

 Hi @d0ugmac1,

I use Flat High Performance (maritime), when I'm in the port, I'm outside service address, and starlink gives me the address 192.168.100.100, and dishy has the address 192.168.100.1. I don't use a Starlink router at all

Hi @denis-odessit 

We tried to re-duplicate your real scenario and we found that the policy routing was working properly. Could you please help to double confirm whether there is any policy routing rule contains your test device that will allow it access the Internet via WAN or WAN1LAN2? According to your routing policy table, there are at least 2 rules contain the IP group as the source. You can provide the screenshots about the ipconfig result on your test device, and provide the screenshots of the IP group.

 

Besides, may I know how did you make the test? Did you only use the PING/tracert command to test? Could you try to access some websites and see when WAN/LAN1 offline, will you still able to access the Internet like searching something online? You can take the screenshots of the result as well.

 

Thanks for cooperation.
