WAN Port Always goes down
@Clive_A I'm also getting this by the way. Is this a problem and how do I prevent this ?
also is this what you need from me for you to analyze ?
I have set my WAN/LAN1 port (where my computer is connected that has an IP address of 192.168.0.7 also has the omada software controller installed and where wireshark is installed and running as well) to mirror the WAN port where my ISP router/modem is connected.
also below are some more details if it can help
i have changed the subnets of the two ISP modem/routers like you've told me earlier by the way if you can notice

That UDP flood is a problem with your WAN. Someone seems to attack your network and that could be the reason why your WAN is down as it floods the network and the online detection got congested. (For the reason why UDP would affect Online Detection, read the KB about Load Balancing and Online Detection.
Hi @herbsss
Thanks for posting in our business forum.
I am not sure what you have configured but both WANs are on a private network. Not sure if you expose anything on the public Internet. This could be a false alarm as well. You might need to monitor this via Wireshark.

@Clive_A Hi, also wanted to consult you on these screenshots from my wireshark. If you see anything suspicious can you enlighten me please ? I apologize for not being so knowledgeable on this as I am new to this and really appreciate your help.
for reference
192.168.112.4 is the ip address of my er7206 assigned by my main ISP modem connected to my er7206 WAN port
192.168.113.2 is the ip address of my er7206 assigned by my secondary ISP modem connected to my er7206 SFP WAN port
if you need the full log, I can send it. it's 5gb I cn upload it via ftp
